part ; lobes % lin. long, } lin. broad, erect, oblong-ovate, obtuse and 
slightly emarginate at the apex, glabrous. Coronal-lobes 1-1 lin. long, 
arising at the base of and about as long as the pollen-bearing part of 
the anthers, erect, thin in the dried state, closely applied to the backs 
of the anthers and easily overlooked. Staminal-column arising from 
the base of the corolla, 1 lin. long; filament part 2 lin. long, rather 
stout ; anthers erect, subquadrate in the adnate basal part, which has 
very small projecting horny wings; pollen-bearing part free, oblong, 
terminated by short oblong-lanceolate acute connivent membranous 
appendages exceeding the coronal-lobes. Style not produced beyond 
the anther-appendages ; terminal part conical, acute. 
Nile Land. British East Africa: Rabai Hills, near Mombasa, Taylor ! 
This species is very distinct from all the other African members of the genus, 
and may: be best likened to M. verruculosa, Decne., from Madagascar, from which it 
differs in its foliage and distinct filamental part to the staminal-column.

Corolla subrotate; tube $—} lin. long, broadly campanulate ; lobes 
1}—1? lin. long, 1 lin. broad, widely spreading, ovate, obtuse, glabrous 
outside, puberulous within, green. Coronal-lobes 1} lin. long, erect, 
overtopping the staminal-column, and adnate to it at their lower part, 
free above, concave on the back and winged on each side at the base, 
the middle part laterally compressed into a broad oblong wing-like
