TL;DR: Historical information and a morphological study of living plants strengthen the view that sterile S. x townsendii arose in c.

TL;DR: Evidence so far suggests that there are distinct host-parasite relationships separating the two species and some examples are described, but the writer retains Z. melosirae and Z. planktonicum as separate species.

TL;DR: Special facets of structure are discussed in an attempt to correlate its organization with the influence of environment and to interpret its taxonomic significance.

TL;DR: In all 101 species and varieties of marine algae are mentioned for S. Tome and Principe, and a series of ‘seasonal coincidences’ likely to influence coastal marine conditions is described for the Gulf of Guinea.

TL;DR: A. incisum 2x is shown to be much more widespread and to be present in hill country, or occasionally in lowlands, from the Himalayas to South India inclusive, and contains a number of genetically determined biotypes differing slightly in morphology but behaving as members of one species when combined into hybrids.

TL;DR: Eight tree species of freshwater swamps are listed, together with a brief description of their adaptations repeatedly occurring in waterlogged soils, and two widely spread West African trees (Anthocleista nobilis, Xylopia staudtii) are described as species with well differentiated pneumatophores.

TL;DR: It is apparent that Chlaenosciadium is a distinct taxon which exhibits affinities with Centella of Drude's hydrocotylinae and Xanthosia, Pentapeltis and Schloenolaena of his Xanthosiinae, and there is a need for a re-evaluation of relationships within the subtribes of the Hydrocotyleae as defined by Drude.
