A new species and a new combination in Phaeostemma (Apocynaceae, Asclepiadoideae, Gonolobinae)

Abstract: Phaeostemma surinamensis Morillo & Krings, sp. nov., a new species of Apocynaceae (Asclepiadoideae, Gonolobinae) is described and illustrated, and the new combination Phaeostemma fucata (Woodson) Morillo & Krings, comb. nov., is made. The new species, known only from a lowland wet forest of Suriname, seems to be closely related to P. fucata, which is an endemic to Ptari-tepui, a sandstone mountain in the southeastern edge of the Venezuelan Guayana.

“…Distinct staminal corona elements are also found in T. cubensis; they are more reduced in T. fuscula, separating the latter and Anemotrochus from Matelea s.str. as currently circumscribed by Morillo (2012) and Morillo & Krings (2014). Further characters possibly segregating the new genera from Matelea s.str.…”

“…Matelea sensu Woodson comprises at least 260 species, and several attempts have been made to describe smaller natural genera (e.g. Stevens 2001;Morillo 2012Morillo , 2013Morillo , 2015Morillo & Krings 2014). However, as Krings (2011: 730) stated, "The synorganization of androecium and gynoecium appears to have facilitated such a myriad of gynostegial structural variation … that it is at times difficult to discern relationships, much less morphological synapomorphies, in the absence of a resolved phylogeny".…”
