TL;DR: The surface sculpturing of the pollen of some species of the taxonomically widely separated genera Harpalyce, Camoensia, Millettia, and of the monotypic Dahlstedtia, which have large red or white flowers adapted for pollination by birds or bats, is coarsely rugulate or verrucate.

TL;DR: Observations made on the anatomy of Phlomis and Eremostachys confirm previous views that the two genera are closely related, but characters such as trichomes and petiole structure can be used to distinguish species and groups of species.

TL;DR: A re-evaluation of Melanospora Corda and similar genera is presented, based mainly on new data obtained by SEM examination of the ascospores, and eight genera are accepted.

TL;DR: It is concluded that the majority of these microfossils derive from non-vascular plants of uncertain affinity which lived on land.

TL;DR: Information from morphology and palynology, together with anatomical, cytological and chemical data, is utilized to examine the status of the genus Phlomis and its close relatives Eremostachys and ParaphLomis, and strongly support the removal of the Chinese species, Ph lomis rolata, to the genus Lamiophlom is.

TL;DR: The view that E. incerta is not closely related to the southern African species is supported by differences in its cuticular ornamentation, lack of lipid bodies in the subsidiary cells, anomocytic stomata and prominent T-pieces at the guard cell poles.

TL;DR: A critical comparison of many characters suggests that the Rubiaceae tribe Anthospermeae is closely allied to the tribe Paederieae, and the genus Neogaillonia Linchevskii belongs to this tribe.

TL;DR: In this paper, the distribution of Trigonobalanus can be more simply explained using the Bering land-bridge as the source of the migration of the species from south-east Asia to Colombia.

TL;DR: Results indicate that growth and litter-fall are seasonal events, but timing varies with species and site, however, reproductive phenology is characteristic of a species, and varies little with time and place.

TL;DR: Taxonomic considerations confirm that the three genera are closely related to one another in the context of the eu-panicoid assemblage as a whole, and that the genus Neurachne itself, although it exhibits variation in photosynthetic pathway, is not amenable to further taxonomic subdivision.

TL;DR: The geographical distribution of the distinctive phenolics suggests a wide spreading of early Malus probably from south-east Asia as far as North America and a later diversification confined almost entirely to Eurasia.

TL;DR: Two cultivated species of commercial coca are now recognized: Erythroxylutn coca Lam.

TL;DR: Three morphological problems were investigated in three species of the Nyctaginaceae: epiphylly, phyllotaxis and placentation, finding no developmental evidence was found to support the derivation of the eight stamens from a two whorled pentamerous androecium.

TL;DR: Cladistic analysis shows Casholdia to display generalized engelhardioid fruit morphology, and adds to the mounting evidence indicating an early Palaeogene radiation of the Juglandaceae.

TL;DR: British Umbelliferae form a natural cohesive taxon, having patterns of habitat distribution, reproductive biology and life-history that distinguish them from other British dicotyledons.

TL;DR: Observations of pollinator behaviour indicate that butterflies frequently move to another plant after visiting one inflorescence, Thus there is a large degree of outcrossing in practice.

TL;DR: Fifty-seven species are endemic to Ceylon and 28 non-endemic species are absent from India, and lists of these and other phytogeographical groupings are given.

TL;DR: It is suggested that increasing numbers of accidental or deliberate fires started by settlers and later inhabitants may have caused the increase in flowering in a population of Xanthorrhoea johnsonii.

TL;DR: All previously reported chromosome counts for Umbelliferae of tropical and southern Africa are summarized and new counts on 35 taxa in 14 genera provided, mostly from Malawi or South Africa.

TL;DR: Anatomical characters do not support any major grouping of species within Chionanthus and provide further evidence that the sections, Eulinocitra and Ceranthus, are untenable.

TL;DR: The arrangement of lateral insertions of Stigmaria ficoides can be considered as a phyllotactic pattern made up of parastichies and orthostichies, which makes deductions about the growth and homology of stigmarian axes.

TL;DR: The genus Merremia is found in the tropical regions of both hemispheres and the climbing species with fast growth rates can become troublesome weeds of cultivation and forestry.

TL;DR: Fourteen binomials are here considered as synonyms of P. tectorius, but several of them warrant retention at varietal rank.

TL;DR: The genera of the Veratreae, a tribe of the Melanthioideae, have many features in common: there are usually many ovules, except for Amianthium, arranged in 2 -4 longitudinal placental rows per carpel; all are bitegmic, basipetal, and campylotropous.

TL;DR: The hybrid material was intermediate between the parental species, and sometimes displayed aberrant trichomes that were contorted in contiguous pairs, as a means of discriminating the three taxa, and in relation to the ecological distributions of the species.

TL;DR: The petiole anatomy of 79 specimens representing 64 species of Baphia has been examined in this article, which provides supporting evidence to be used in the infra-generic classification.
