Thomas5703 ( K[ K000043257]!), syn. nov.   Notes. –  Sabicea arachnoideawas described based on three very poor collections from Sierra Leone, and has never been recollected since. It is supposedly characterised by dense globose inflorescences, linear or filiform calyx lobes, and discolorous leaves with arachnoid indumentum beneath (HUTCHINSON & DALZIEL, 1931; HEPPER, 1963). A reexamination of the syntypesshows that the so-called inflorescences are actually leaf galls, which bear structures resembling calyx lobes at first sight – similar galls have been reported in  S. sciaphilanthasubsp. hirsutaZemagho, O. Lachenaud & Sonké(ZEMAGHO et al., 2017). In vegetative characters the syntypesof  S. arachnoideaare inseparable from  S. discolor, which has also been collected at Yonibana ( N.W. Thomas 5038, K) and it is therefore obvious that the two species are identical. Among the three syntypesof  S. arachnoidea, the most complete collection [ K000043317] is designated here as lectotype. Theoriginal description of  S. discolor(STAPF, 1905) is also based on three syntypes, as the author states: “near Monrovia and in the Sinoe Basin, Whyte. Also in the Gold Coastnear Akwapim, at  1400 feet, Murphy(herb. Johnson, 679)”. Oneof the  Whytecollections, which is slightly better than the others, is selected here as lectotype. 3470697313 K Whyte Liberia Sinoe Basin Sinoe Basin 14 291 K000043317 1 Sinoe lectotype 3470697335 1900-03 K Murphy Ghana Akwapim 14 291 K000043305 1 syntype 3470697319 K Whyte Liberia Monrovia 14 291 K000043318 1 Montserrado 3470697323 1914-11-11 K N.
