Baissea

The genus Baissea is restricted to continental Africa and belongs to tribe Baisseeae , which also includes the genera Motandra A. DC. , Oncinotis and Dewevrella De Wild. ( ENDRESS et al., 2018). Characters of the tribe include a lianescent (or rarely suffrutescent) habit, small flowers with a right-contorted corolla aestivation, anthers tailed at base, presence of a disk, fruits in narrow paired follicles, and seeds with an apical tuft of hairs. Additional characters of Baissea are the subsessile stamens included in the corolla tube (or with only the tips exserted), anthers with straight and acute basal tails, and the absence of coronal appendages. The genus was revised by VAN DILST (1995) , who recognised 18 species.

In the current paper a distinctive new species from Gabon, Baissea atrobrunnea O. Lachenaud , is described, and three species are resurrected from synonymy: B. concinna Stapf ex Hutch. & Dalziel, B. congensis (R.D. Good) Jongkind , and B. subsessilis (K. Schum.) Stapf ex Hutch. & Dalziel. The last two were previously included in B. campanulata (K. Schum.) De Kruif , while B. concinna was regarded as a synonym of B. lane-poolei Stapf.
