The new species is closely related to Onosma subulifolia Riedl from which it is distinguished. Onosma anatolica is readily distinguished from Onosma subulifolia by its sterile shoots, the green-grey stem indu...

Leaf ontogenesis is determinant for the establishment and regulation of its structural functional properties, in addition to being an excellent tool assignment different groups angiosperms. Even though importance leaf morphology anatomy taxonomic use well known, few studies have addressed processes ontogeny Melastomataceae. Herein, we sought define ontogenetic steps Trembleya phlogiformis, high...

A new Australian species of functionally dioecious bush tomato of Solanum subgenus Leptostemonum is described. Solanum ossicruentum Martine & J.Cantley, sp. nov., is thought to be allied with members of the problematic "Dioicum Complex" lineage, but differs in its short silvery indumentum, long calyx lobes, larger stature, and an unusual fruit morphology that may represent "trample burr" seed d...

Melanthiaceae s.l. comprises five tribes: Chionographideae, Heloniadeae, Melanthieae, Parideae, and Xerophylleae--each defined by distinctive autapomorphies. The most morphologically diverse tribe Melanthieae, now with seven genera, had not been subject to rigorous phylogenetic character study prior to the current series of investigations that also include an overview of the family. Data from o...

A new species from the wet miombo woodlands of Tanzania and Angola, Argyrella richardsiae Veranso-Libalah & G.Kadereit, sp. nov. (Melastomataceae, Melastomateae), is described and illustrated.
