A striking species, the bright scarlet or orange yellow corolla- 

 limb attaining 6 cm. in diameter. This is notably in keeping with 

 the fact that the calyx-lobes are not modified into an attractive 

 lamina, the function of attraction being performed by the corolla 

 (v. ante, p. 233). 



/3 rotundifolia Wernham, var. nov. Foliis parvis suborbicu- 

 laribus ca. 3 cm. x 2-5 cm. vel oblongis 3-5 cm. x 2-5 cm. petiolo 

 4 mm. longo.

The species may include other varieties. The following speci- 

 men, described as a small tree, is probably referable to the same 

 species, but it bears fruits only and no flowers. If so, it may be 

 regarded as the following variety : — 



y psilocarpa Wernham, var. nov. Pedunculis longiusculis, 

 calycis lobis brevioribus, fructu oblongo glabro.

A lowly shrub, according to the description nearly related to 

 M. elegans, I have not seen a specimen.

Eemarkable for the very ample calyx-lobes, attaining 2 cm. x 

 1 cm., and the stout corolla-tube, over 6 mm. in the widest part. 

 As Hiern suggests (Fl. Trop. Afr. iii. 71), this may prove to be 

 .V. rufa A. Eich. in Mem. Soc. Hist. Nat. Par. v. 246 (1829).

Sierra Leone. It has been suggested that this may prove to 

 be the same as M. grandiflora Benth. (see previous species). 

 The original description is altogether inadequate.
