 from the axils of the upper leaves. Bracts sessile, f-lj in. long, \-\ in. 

 broad, ovate, oblong-ovate or ovate-lanceolate, acute, subtruncately 

 rounded at the base. Involucre shortly pedunculate, excluding the 

 glands, about 1 lin. in diam., somewhat pear-shaped, glabrous outside 

 and within, with 4 glands and 5 oblong-ovate or subquadrate slightly 

 notched and minutely ciliate lobes ; glands |-| lin. in their greater 

 diam., crescent-shaped, with 2 linear horns J lin. or perhaps more long, 

 often toothed at the apex. Capsule exserted, about 2 lin. in diam.,

Tliis is very closely allied to E. schimperiana, Scheele, and structurally is only 

 distinguishable by tlie larger horns of the involucral glands ; possibly it may be only 

 a form of that species and like it varies very much in stature and appearance, some 

 of the specimens from the moister regions near the Equator being much larger than 

 those from Abyssinia, whilst others are identical with them. Pax has described it 

 as perennial, but his type specimens and all others that 1 have seen with roots are 

 annual.
