3 The possible location of the authentic specimens is in “Musa” ( Forsskål 1775: 103), West Yemen, probably Ta’izz governorate, near Mocha [“Taaes, Musa vicus Mochhae proximus” ( Forsskål 1775: 90)].

Typification of Orygia mucronata :—The specimen cited is certainly part of the original Peters’ collection. The authentic material at B has been missing, perhaps, since the mid-1940s (Robert Vogt, pers. comm.). The specimen at K bears a perennial herb or a subshrub collected in the early reproductive stage with two unripe fruits and many flowers. Despite this, the seeds distinctly possess the papillae-like outgrowths on the seed surface like in C. decumbens . Klotzsch (in Peters 1862–1864) distinguished O. mucronata from O. decumbens s. str. in several characters (suffruticose habit, absence of the petals, and different number of stamens). The restricted number of flowers on the authentic specimen or lack of additional material does not allow a precise confirmation of Klotzsch’s conclusion about the total absence of petaloid staminodia in all perennial individuals of Corbichonia from East Africa. Further field investigations need to clarify whether perennial forms of C. decumbens from Eastern Tropical Africa ( Ethiopia, Kenya, Tanzania, and Mozambique) are distant from annual Corbichonia , or whether C. decumbens can form both annual and perennial life forms. However, such suffruticose individuals are seen on the specimens from diverse African or Asian locations. The synonymization of Corbichonia decumbens with Orygia mucronata can still be accepted, but with some doubt.
4 Described from East India without precise location: the type specimens of G. trianthemoides are not known, but determinations of B. Heyne were seen at Kew herbarium.
