TL;DR: Based on extensive molecular, cytological, and morphological studies, most of the North American species of Arebas (Brassicaceae) are recognized herein as members of the genus Boechera.
Abstract: Based on extensive molecular, cytological, and morphological studies, most of the North American species of Arebas (Brassicaceae) are recognized herein as members of the genus Boechera. Morphological differences between the two genera are discussed, and species formerly placed in Arabis and not included here in Boechera are assigned to other genera. Thirty-two new combinations in Boechera are proposed: B. bodiensis (Rollins) Al-Shehbaz, B. breweri (S. Watson) A1Shehbaz, B. canadensis (L.) Al-Shehbaz, B. constancei (Rollins) Al-Shehbaz, B. cusickii (S. Watson) Al-Shehbaz, B. dispar (M. E. Jones) Al-Shehbaz, B. falcifructa (Rollins) Al-Shehbaz, B. fruticosa (A. Nelson) Al-Shehbaz, B. glaucovalvula (M. E. Jones) Al-Shehbaz, B. hastatula (Greene) Al-Shehbaz, B. hirshbergiae (S. Boyd) Al-Shehbaz, B. hogmanii (Munz) Al-Shehbaz, B. inyoensis (Rollins) Al-Shehbaz, B. johnstonii (Munz) Al-Shehbaz, B. koehteri (T. J. Howell) Al-Shehbaz, B. Iaevigata (Muhlenberg ex Willdenow) Al-Shehbaz, B. missouriensis (Greene) Al-Shehbaz, B. ophira (Rollins) Al-Shehbaz, B. parishii (S. Watson) Al-Shehbaz, B. patens (Sullivant) Al-Shehbaz, B. perstellata (E. Braun) A1Shehbaz, B. pinzlae (Rollins) Al-Shehbaz, B. platysperma (A. Gray) Al-Shehbaz, B. pygmaea (Rollins) Al-Shehbaz, B. rectissima (Greene) Al-Shehbaz, B. repanda (S. Watson) Al-Shehbaz, B. rigidissima (Rollins) Al-Shehbaz, B. rollei (Rollins) Al-Shehbaz, B. shortii (Fernald) Al-Shehbaz, B. stricta (Graham) Al-Shehbaz, B. subpinnatifida (S. Watson) Al-Shehbaz, and B. tiehmii (Rollins) A1Shehbaz. Three recently described species, Arabis c(zZderi C. A. Mulligan, A. murraya G. A. Mulligan, and B. glareosa Dorn, are reduced to synonymy of B. divaricarpa (A. Nelson) A Love & D. Love, B. Iyallii, and B. gunnisoniana (Rollins) W. A. Weber, respectively.

TL;DR: Comparative survey shows that Rohdea differs from eight species of Tupistra7 one species of Campylandra (C. aurantiaca), and two species of Gonioseypha (G. eucomoides) mainly by the degree of thickness of the perianth and in the shape and length of thePerianth lobes, so those species of the last three genera are here transferred to RohdeA.
Abstract: Comparative survey shows that Rohdea differs from eight species of Tupistra7 one species of Campylandra (C. aurantiaca), and one species of Gonioseypha (G. eucomoides) mainly by the degree of thickness of the perianth and in the shape and length of the perianth lobes. As these differences do not seem to deserve generic delimitation, those species of the last three genera are here transferred to Rohdea. As a consequence, the following 10 new combinations are proposed: Rohdea aurantiaca (Baker) N. Tanaka, Rohdea chinensis (Baker) N. Tanaka, Rohdea delavayi (Franchet) N. Tanaka, Rohdea emeiensis (Z. Y. Zhu) N. Tanaka, Rohdea ensifolia (F. T. Wang & Ts. Tang) N. Tanaka, RoAdea eucomoides (Baker) N. Tanaka, Rohdea jinshanensis (Z. L. Yang & X. G. Luo) N. Tanaka, Rohdea longipedunculata (F. T. Wang & S. Yun Liang) N. Tanaka, Rohdea tonkinensis (Baillon) N. Tanaka, and Rohdea verruculosa (Q. H. Chen) N. Tanaka.

TL;DR: A new species, Ephedra rituensis Y. Yang, D. Fu & G. Zhu, is described and illus- trated and should be as- cribed toEphedra sect.
Abstract: A new species, Ephedra rituensis Y. Yang, D. Z. Fu & G. Zhu, is described and illus- trated. This species is similar to Ephedra interme- dia Schrenk & C. A. Meyer in having bi- or tri- ovulate cones, and to E. saxatilis Royle ex Florin in having strong and well-developed woody stems and branchlets. It differs from E. intermedia mainly by the shorter micropylar tube straight or slightly curved and the less connate bracts of the upper- most whorl of female cones, and from E. saxatilis by the longer micropylar tube, the bi- or tri-ovulate female cones, more pairs or whorls of bracts, and the smaller seeds. The new species should be as- cribed to Ephedra sect. Pseudobaccatae Stapf since its female cones bear fleshy bracts at maturity.

TL;DR: A new species of Pinus fragilissima Businsky, described from southeastern Taiwan, appears to be most closely related to E luchuensis Mayr, endemic to the Nansei Islands, and to P taiwanensis Hayata, which is circumscribed here as a Taiwan endemic with the exclusion of superficially similar but probably unrelated mainland Chinese pines.
Abstract: Pinus fragilissima Businsky (Pinaceae), a new species of Pinus subg. Pinus, is described from southeastern Taiwan. Comprised of trees with very sparse crown and fragile, symmetrical, S9 cm long cones with often flat apophyses, it appears to be most closely related to E luchuensis Mayr, endemic to the Nansei Islands, and to P taiwanensis Hayata. The latter is circumscribed here as a Taiwan endemic with the exclusion of superficially similar but probably unrelated mainland Chinese pines. These three allied species are classified here as the sole representatives of Pinus subg. Pinus ser. Luchuenses E. Murray.

Abstract: Mostuea muricata, an American species from a predominantly African genus, is described, illustrated, and compared with the African M. brunonis and the American M. surinamensis, from which it is distinguished mainly by its muricate fruits and rugose, glabrous, and viscose seeds. This species was collected in the Brazilian states of Mato Grosso and Sao Paulo, and its finding represents a southward extension of the range of Mostuea in South America, before now known only in Suriname and northern Brazil. RESUMEN. Se describe y ilustra Mostuea muricata, una especie americana de un genero principalmente africano. Se la compara con la especie africana M. brunonis y con la especie americana M. surinamensis, de las cuales se diferencia especialmente por sus frutos muricados y sus semillas rugosas, glabras y viscosas. Esta especie fue colectada en los estados brasilenos de Mato Grosso y Sao Paulo, y su hallazgo representa una extension austral del area geografica del genero en Sudamerica, que hasta ahora se conocia solo en Surinam y el norte de Brasil.
TL;DR: The newly described Casearia guevarana has an undivided style free stamens, and free interstaminal disc lobes and is subdivided into six sections, the largest and only one to occur outside of the Neotropics, is section CasearIA.
Abstract: Casearia guevarana, a new species of Flacourtiaceae from the coastal dunes of the Natural Reserve "E1 Morro de la Mancha," from the states of Veracruz and Tabasco, Mexico, is described and illustrated. Its affinities with the closely related species C. aculeata Jacquin and C. obovata Schlechtendal are discussed. This new species differs from its congeners by having broadly obtuse leaf apices, large, six-channeled fruits, and larger more numerous seeds. RESUMEN. Se describe como nueva a Casearia guevarana (Flacourtiaceae) de las dunas costeras de la Reserva Natural E1 Morro de La Mancha, Veracruz y Tabasco, Mexico. Esta nueva especie esta cercanamente relacionada con Casearia aculeata Jacquin y C. obovata Schlechtendal, de las que se distingue por presentar el apice de las hojas ampliamente obtuso, frutos 6-acanalados y de mayor tamano, con semillas mas grandes y mas numerosas. Ke words: Casearia, coastal, dunes, Flacourtiaceae, La Mancha, Mexico, Tabasco, Veracruz. In 1998, during an inventory of trees and shrubs associated with an evergreen seasonal rainforest at the Nature Reserve and Clenter for Coastal Research at La Mancha ((LICOLMA) in Veracruz! Mexico, a tree rarely seen in the middle stratum of the forest was sampled and reported. At the time, this tree was totally lacking reproductive structures so that it was only possible to classify it with any certainty to the genus Casearia (Flacourtiaceae). However, during two years subsequent to this initial find, flowers (2000) and fruits (2001) were obtained. After having examined and compared vouchers of C. aculeata and C. obovata with those recently collected from the Natural Reserve of La Mancha, it NOVON 13: 30-33. 2003. was found that they corresponded to an undescribed species. Based upon this additional information this specimen was considered to represent a nez species. Its detailed description is reported below. Caseflria Jacquin is a pantropical genus of about 180 species of trees and shrubs. It is most diverse in (sub)tropical Central and South America, where some 75 species occur, including 8 in Veracruz. The genus is subdivided into six sections, the largest and only one to occur outside of the Neotropics, is section Casearia. Three of the sections are represented in Veracruz: sect. Crateria, sect. Pipcerea, and sect. Case(lria. Section Casearia is further divided into six informal groups, three of which occur in Veraeruz i.e. Nitidae Aculeatae, and Decandrae. The newly described Casearia guevarana has an undivided style free stamens, and free interstaminal disc lobes. These characters place the species in Casearia sect. Casearia. The following characters place the species in section Casearia, group Aculeatae; an undivided style, at times obsolete, and capitate stigma; plants generally with spines, at times not present in herbarium vouchers; and stamens generally 8, flowers more or less tubular, base oltuse-truncate often slightly swollen just before flowering. Two other species of the Aculeatae group occur in Veracruz, C. aculeata and C. obov-
TL;DR: A novelty of Mesoamerican Jacquinia (Theophrastaceae) species with white, yellowish, or cream-colored flowers is presented and a key for their identification is provided.
Abstract: AE9STRACT. A synopsis of Mesoamerican Jacquinia (Theophrastaceae) species with white, yellowish, or cream-colored flowers is presented. A key for their identification is provided. All of these species are restricted to northern Mesoamerica. Among these taxa Jacquinia sak-lol Carnevali, HernandezAguilar & Tapia-Munoz, from the state of Quintana Roo in the Mexican Yucatan Peninsula, is proposed as new. The new entity is described and illustrated. The proposed novelty is related to Jacquinia paludicola Standley, but it is a shrub and features smaller, more coriaceous leaves with a revolute margin and larger flowers.
TL;DR: A new species of Tillandsia is pro- posed, most similar to T. brachycaulos in flower and bract color, but the elongated inflorescences resemble those of T. balbisiana, although the branches are much shorter.
Abstract: A new species of Tillandsia is pro- posed. It is similar to Tillandsia brachycaulos Schlechtendal and Tillandsia balbisiana Schultes f., two sympatric species. The new species is most similar to T. brachycaulos in flower and bract color, but the elongated inflorescences resemble those of T. balbisiana, although the branches are much shorter.
TL;DR: In this article, the reinstatement of M. viminea Greene at the specific rank is supported on the basis of distinctive morphology and biological isolation, and a key is included to separate M. stoneana from all of the perennial Monardella species known to occur in San Diego County, California.
Abstract: Monardella stoneana (Lamiaceae), a narrow endemic from northern Baja California, Mexico, and southern San Diego County, California, is described and illustrated. Differences in leaf and bract morphologyS pubescence, stem glands, and habitat separate it from M. Iinoides A. Gray and M. Odoratissima Bentham, apparently its closest relatives. The reinstatement of M. viminea Greene at the specific rank is supported on the basis of distinctive morphology and biological isolation. A key is included to separate M. stoneana from all of the perennial Monardella species known to occur in San Diego County, California.

TL;DR: New rank is proposed for Epipactis humilior, formerly treated as a variety of E. helleborine, which distinctly differs from the latter by having a slender, creeping, elongated rhizome, ovate-lan- ceolate or lanceolate leaves 2-3 cm wide and scarcely or slightly scabrous adaxially.
Abstract: New rank is proposed for Epipactis humilior (Tang & Wang) S. C. Chen & G. Zhu and E. helleborine (L.) Crantz var. tangutica (Schlech- ter) S. C. Chen & G. Zhu. Epipactis humilior was formerly treated as a variety of E. mairei Schlech- ter, but distinctly differs from the latter by having a slender, creeping, elongated rhizome, ovate-lan- ceolate or lanceolate leaves 2-3 cm wide and scarcely or slightly scabrous adaxially. Epipactis helleborine var. tangutica is characterized by pos- sessing on the epichile two much larger fleshy calli rather than small semiorbicular warty lamellae seen in E. helleborine.
TL;DR: Cipura gigas is a new species of this Neotropical genus of nine species that extend from Paraguay in the south to Cuba and Mexico in the north and is restricted to the Orinoco basin of eastern Colombia and adjacent Venezuela.
Abstract: Cipura gigas is a new species of this Neotropical genus of nine species that extend from Paraguay in the south to Cuba and Mexico in the north. Apparently most closely related to the widespread C. paludasa, C. gigas is distinguished by its height (50-100 cm), the large bulb (ca. 3 cm diam.) with resinous tunics, basal leaves that are mostly S10 mm wide, lilac-purple flowers, and the inner tepals that form a narrow-mouthed urn-like cup 1> 13 mm long. The species is restricted to the Orinoco basin of eastern Colombia and adjacent Venezuela. We provide a revised key to the genus.
TL;DR: Notopleura (Bentham & Hooker f.) Bremekamp is a Neotropical genus of about 100 species that was formerly included in Psychotria, but differs from that in its low succulent habit, stipules with a single usually glandular interpetiolar appendage, and terminal or often pseudoaxillary inflorescences.
Abstract: Notopleura (Bentham & Hooker f.) Bremekamp is a Neotropical genus of about 100 species that was formerly included in Psychotria, but differs from that in its low succulent habit, stipules with a single usually glandular interpetiolar appendage, and terminal or often pseudoaxillary inflorescences. Notopleura is widely distributed in wet habitats and includes two subgenera: subgenus Notopleura, which comprises terrestrial, usually unbranched plants and includes most of the species in the genus, and subgenus ViscogogaS which comprises epiphytic, usually branched plants.

Taylor of Ecuador, which has again been confused with N. aggregata; and N. zarucchiana C. M. Taylor of montane Colombia, which has also been confused with N. macropodantha. Also in subgenus Notopleura, the correct names and their authorship are discussed for the species N. Iongipedunculoides (the formal new combination made here), N. Iongissima Bremekamp, and N. micayensis. In subgenus Viscagoga five new species are described and illustrated: N. bahiensis C. M. Taylor, which is similar to N. multiramosa (Steyermark) C. M. Taylor; N. cocleensis C. M. Taylor from western Panama, which has been confused with N. guadalupensis (DC.) C. M. Taylor; N. elegans C. M. Taylor from Costa Rica and western Panama, which has also been confused with N. guadalupensis; N. episcandens C. M. Taylor & Lorence from eastern Panama, which has been confused with N. maxonii (Standley) C. M. Taylor; and N. vargasiana C. M. Taylor from Ecuador, which again has been confused with N. guadalupensis.
