TL;DR: The Tribe Termitomceteae (Jfilich) Singer has been placed within Tricholomataceae Heim ex Pouzar by Singer (1986), close to the Tribe Lyophylleae Kiihner ex Bas, based upon the presence of siderophilous granulation detected in the basidia.
Abstract: Termitomyces was described by Heim (1942a) for a group of termitophilous agarics found in central Africa The Tribe Termitomceteae (Jfilich) Singer has been placed within Tricholomataceae Heim ex Pouzar by Singer (1986), close to the Tribe Lyophylleae Kiihner ex Bas, based upon the presence of siderophilous granulation detected in the basidia Jiilich (1981) raised the group to family level, Termitomycetaceae, and placed it alongside Amanitaceae Roze and Torrendiaceae Jiilich in the Amanitales Jiilich Pegler (1986) preferred to accommodate the genus Termitomyces Heim within Pluteaceae Kotl & Pouzar, largely on the basis of the pluteoid habit, with densely crowded, free lamellae which rapidly decay, the pink spore deposit, the type of hymenial cystidia, and the basidiospores which often develop a wall-structure with two teguments and the presence of an open-pore hilum (Pegler & Young, 1971) The main difference from other genera in Pluteaceae lies in a hymenophoral trama with divergent, rather than convergent, hyphae in the basidiomatal primordia, together with the termitophilous association Singer (1945) separated Termitomyces microcarpus (Berk & Broome) Heim in order to propose a new genus, Podabrella, on the basis of the epigeous habit and lack of pseudorhizal development, and to which he added some neotropical, non-termitophilous species Zang (1981) examined some collections from Yunnan Province, P R China, and proposed a new genus, Sinotermitomyces, which may be separated from Termitomyces as follows:

TL;DR: Twelve species of the pantropical genus Parkia R.Br.
Abstract: Summary. Twelve species of the pantropical genus Parkia R.Br., which occur from NE India to Fiji, are enumerated and illustrated. They include petai (P. speciosa) which is eaten as a spicy vegetable in SE Asia. All belong to section Parkia, and they appear to be more closely related to the African species of this section than to the American ones. A key and distribution maps are given. Scattered references indicate that pollination is by both large and small pteropodid bats, and a variety of animals, including monkeys and birds, are potential dispersal agents.
TL;DR: The infrageneric classification of Allium proposed at the International Symposium on Taxonomic Problems and Genetic Resources of the genus Allium, held in Gatersleben in 1991, and published later in preliminary format within the proceedings of the conference, contains some new infragenersic taxa and combinations.
Abstract: The infrageneric classification of Allium proposed at the International Symposium on Taxonomic Problems and Genetic Resources of the genus Allium, held in Gatersleben in 1991, and published later in preliminary format within the proceedings of the conference (Hanelt, Hammer & Knuipffer 1992), contains some new infrageneric taxa and combinations. Their publication is validated as follows (compare Hanelt et al. 1992).

TL;DR: Three new species to the Turkish flora are described and illustrated; Allium turcicum, Bellevalia anatolica and Muscari anatolicum (Hyacinthaceae), adding to those species included in the most recent revision of Turkish geophytes in Flora of Turkey.
Abstract: Summary. Three new species to the Turkish flora are described and illustrated; Allium turcicum (Alliaceae), Bellevalia anatolica and Muscari anatolicum (Hyacinthaceae). Recent specimens collected by the authors and N. Stevens from Turkey included three undescribed geophyte species. This adds to those species included in the most recent revision of Turkish geophytes in Flora of Turkey (Davis 1984, 1988) and further demonstrates the importance of studying living material. Details of the collecting expeditions and voucher specimens for cytological work are given in the following paper (Johnson 1994).
TL;DR: A study was carried out of an area of 2500 m2 of cerrado vegetation in Mato Grosso State, Brazil which contained 187 individual trees of 26 species in 22 genera and 18 families of which the species with the highest importance value were Curatella americana and Lafoensia pacari.
Abstract: A study was carried out of an area of 2500 m2 of cerrado vegetation in Mato Grosso State, Brazil. The quadrat contained 187 individual trees of 10 cm diameter or more of 26 species in 22 genera and 18 families. The species with the highest importance value were Curatella americana L. (Dilleniaceae) and Lafoensia pacari A. St. Hil. (Lythraceae). The plot was on acid sandy soil (73% sand) with a pH of 5.1. Phenological observations were carried out over a one year period and are presented in a diagram.

TL;DR: The genus Endostemon N.E.Br.
Abstract: Summary. The genus Endostemon N.E.Br., widespread in tropical Africa and with one species in India, is revised and 18 species, placed in 4 sections, are recognized. One new species, Endostemon albus A. J. Paton, Harley & M. M. Harley, and two new sections, sects Oblongi Ayob. ex A. J. Paton, Harley & M. M. Harley & Leucosphaeri A. J. Paton, Harley & M. M. Harley are described. Endostemon leucosphaerus (Briq.) A. J. Paton, Harley & M. M. Harley is transferred into Endostemon from Erythrochlamys Briq. The circumscription of Endostemon is discussed and the morphological and palynological differences between Endostemon and related genera are illustrated. Endostemon can be distinguished from related genera by its short, villous anthers which are attached to the corolla just below the throat, a small shield-like swelling near the base of the style just above the nutlets and by the pollen having short colpi and alternately wide and narrow mesocolpia. The phytogeography of the genus is discussed. There are two centres of diversity, Angola and the Somalia-Masai region, each having different components.
TL;DR: The new species described in this paper came to light during the preparation of the account of Eriocaulaceae for the "Flora of Ceylon", a large genus of about 400 species, whose taxonomy presents a number of special problems.
Abstract: The new species described in this paper came to light during the preparation of the account of Eriocaulaceae for the "Flora of Ceylon". Eriocaulon is a large genus of about 400 species, whose taxonomy presents a number of special problems. Vegetatively the species are mostly rather uniform, the majority having a basal rosette of narrow leaves, from which capitula arise on leafless scapes. However, dimensions of both leaves and scapes are much influenced by environmental factors, especially water level, in the marshy or aquatic habitats in which they grow. The capitula are packed with numerous tiny (often only 1 -3 mm) unisexual flowers, which are both complex and also more variable than has sometimes been recognized hitherto. An admirable discussion of the weight which should be awarded various characters, based on a very detailed study, can be found in Hess (1955). In particular, the relative dimensions of the floral parts can alter dramatically at maturity, and the arrangement of the sexes within the capitulum, whether mixed together or in separate bands, is certainly not as constant as has been supposed and may also depend to some extent on environment. For example, in E. ceylanicum Korn. the peripheral flowers are female in Simpson 9042 and male in Koyama 13516. In E. philippo-coburgi Wawra (syn. E. atratum K6rn. var. major Ruhland) the capitula are often entirely male. In recent years the morphology of the seed coat has been recognized as a useful taxonomic aid in Eriocaulaceae (Nair, 1987; Giulietti et al., 1988). During the course of this study nearly all the Eriocaulon species present in Ceylon have been surveyed, and SEM photographs of the seed surface structure of some of these species are included in this paper. In fact, seed morphology has been of great help in distinguishing species for the Ceylon Flora account as each species, or at least each species complex, appears to have its own unique and constant pattern, as already noted by Nair (1987). Although a high resolution microscope is required to discern fine detail, gross differences in colour and patterning can be seen with a hand lens. Seeds are ellipsoid or subglobose and their colour varies from yellow to a rich chestnut brown, the patternings often appearing as white flakes or striae
TL;DR: There are four species recognized in Hickelia, three of which are known from Madagascar; a fourth described here as a new species, H. africana S. Dransf.
Abstract: Summary. The bamboo genus Hickelia A. Camus is revised and a key to the species is provided. Pseudocoix A. Camus, a genus from Madagascar, is shown to be synonymous with Hickelia, and its single species is transferred to Hickelia as H. perrieri, a new combination. Altogether there are four species recognized in Hickelia, three of which are known from Madagascar; a fourth described here as a new species, H. africana S. Dransf., is found in Tanzania. Morphology of branching, inflorescences and spikelets is discussed. An extended description of H. madagascariensis is presented. Hickelia is considered to be related to Nastus Juss.
TL;DR: These are here described outside of the context of the proposed Botanical Inventory in accordance with the Inventory's requirements.
Abstract: During work on a botanical inventory of Brunei Darussalam, a collaborative programme between Forestry Department Brunei Darussalam and the Royal Botanic Gardens, Kew, it became apparent that two new species of Schismatoglottis and a new species of Homalomena were represented among the collections at Kew (K), Edinburgh (E), Aarhus (AAU), Leiden (L) and the Forestry Department, Brunei (BRUN). These are here described outside of the context of the proposed Botanical Inventory in accordance with the Inventory's requirements.
TL;DR: The chromosome numbers of three new taxa, (one Alliaceae and two Hyacinthaceae) from Turkey are reported, together with the first chromosome record for the Turkish endemic, Muscari discolor, 2n = 18, (2x).
Abstract: The chromosome numbers of three new taxa, (one Alliaceae and two Hyacinthaceae) from Turkey are reported, together with the first chromosome record for the Turkish endemic, Muscari discolor, 2n = 18, (2x). The new taxa are Allium turcicum 2n = 16, (2x); Bellevalia anatolica 2n = 8, (2x); and Muscari anatolicum 2n = 18, (2x) and 2n = 36, (4x). One individual of A. turcicum was found to have an extra chromosome, 2n = 17 (16 + 1), a rare case of trisomy.

TL;DR: Although only known from plants cultivated in Munich and Kew, the species described here is highly distinctive and has significant horticultural potential; therefore it deserves recognition.
Abstract: The genus Scindapsus Schott (1832) contains about 35 species occurring from northeastern India to western Polynesia. The genus is divisible into two informal groups based on vegetative morphology. Some species, e.g. S. altissimus Alderw. (Alderwerelt van Rosenburgh 1922), are huge few-stemmed climbers reaching the canopy of emergent trees and commonly exceeding 60 m in height. However, most species are diffuse climbers, usually occuring on small trees or rock faces, and seldom exceeding 5 m in height. The species described here belongs to the second group. Although only known from plants cultivated in Munich and Kew, it is highly distinctive and has significant horticultural potential; therefore we believe it deserves recognition.
TL;DR: The gross morphology is discussed; features of the trimerous flowers and the endocarps composed of three fused pyrenes indicate that Rosselia belongs in the tribe Canarieae, followed by Protieae, and the pollen is found to be a distinctive type dissimilar to all known pollen types in the Burseraceae.
Abstract: Summary. A new genus of Burseraceae, Rosselia Forman, is described. Its single species R. bracteata Forman is known from only two collections made on Rossel I. in the Louisiade Archipelago off the southeastern end of Papua New Guinea. The genus is distinctive in the conspicuous foliaceous bracts borne along the elongate inflorescences. The gross morphology is discussed; features of the trimerous flowers and the endocarps composed of three fused pyrenes indicate that Rosselia belongs in the tribe Canarieae. The anatomy of the leaf and young stem is described and the presence of features typical of Burseraceae is confirmed. A comparison is made of four significant anatomical characters of Rosselia and their distribution in the rest of Burseraceae; the greatest resemblance is found to be with tribe Canarieae, followed by Protieae. The pollen morphology is described and the pollen is found to be a distinctive type dissimilar to all known pollen types in the Burseraceae. Certain features, however, notably the lalongate, costate endoapertures, occur in other genera of the family. The unusual pollen of Rosselia is considered in the light of other pollen types unique to particular genera of Burseraceae. Reasons for the disparity of the pollen of Rosselia within the family are suggested.
