Taxonomic revision of Phyllanthus (Phyllanthaceae) in Madagascar and the Comoro Islands IV: subgenus Anisonemoides section Pseudogomphidium and incertae sedis
This paper is the fourth part of the taxonomic revision of the genus Phyllanthus in Madagascar and the Comoro Islands. Here we treat Pseudogomphidium Ralim. & Cable sect. nov. consisting of nine species that we misplaced in the subgenus Gomphidium (Baill.) G.L.Webster in our previous paper. Two species are new...Ralimanana, Hélène ; Cable, Stuart

A new species of Myrsine (Primulaceae-Myrsinoideae) from New Guinea
Myrsine exquisitorum Utteridge & Lepschi (Primulaceae-Myrsinoideae) is described and illustrated as a new species endemic to the Western Highlands Province from Papua New Guinea. The new species is unique in the relatively large, almost orbicular leaves with entire margins, and the tetramerous flowers arranged in axillary fascicles without forming short...Utteridge, Timothy M.A. ; Lepschi, Brendan J.

Three new species segregated from Phebalium squamulosum subsp. squamulosum (Rutaceae) based on morphological and phytochemical data
Phebalium graniticola I.Telford & J.J.Bruhl, P. stellatum I.Telford & J.J.Bruhl and P. sylvaticum I.Telford & J.J.Bruhl are segregated as new species from Phebalium squamulosum Vent. subsp. squamulosum. Essential oil data support the recognition of these species as distinct. Distributions of the new species are mapped, and their habitat and conservation status discussed....Telford, Ian R.H. ; Sadgrove, Nicholas J. ; Bruhl, Jeremy J.

Comparative carpological study of Poikilospermum (Urticaceae) in relation to taxonomy
Fruit morphology and the anatomical structure of the pericarp, fruiting perianth, and seed coat were studied in 15 species of Poikilospermum, a genus whose position within the Urticaceae has long been controversial. Possible evolutionary trends of their transformation are suggested for both subgenera; plesiomorphies were found in P. oblongifolium and...Kravtsova, T. I. ; Moore, A. ; Wilmot-Dear, C.

Genera Palmarum - The Evolution and Classification of the Palms
Since the publication of the first edition of Genera Palmarum in 1987, there has been an explosion of interest in this quintessentially tropical flowering plant family. Palms tend to attract attention, perhaps because of their recognisable rather simple growth form, their ecological and economic importance, or indeed simply because of... -

From the frying pan: an unusual dwarf shrub from Namibia turns out to be a new brassicalean family
Tiganophyton karasense, an evergreen dwarf shrub, is described as a new species. A new genus and family are also proposed for it in the order Brassicales. Phylogenetic analysis of DNA sequence data indicate that Tiganophyton is sister to Bataceae/Salvadoraceae, and all three sister to Koeberliniaceae. First realized to be undescribed... -

A revision of the African genus Mesanthemum (Eriocaulaceae)
Mesanthemum is a genus comprising 16 species in the family Eriocaulaceae and is native to Africa and Madagascar. Eriocaulaceae are characterised by a basal tuft or rosette of narrow leaves and small flowers in heads. Mesanthemum can be recognised by diplostemonous flowers and fused glandular pistillate petals. While most Mesanthemum...Liang, Yuxi ; Phillips, Sylvia M. ; Cheek, Martin ; Larridon, Isabel
