This variety differs from E spinulosum, subsp. africanum, in the narrower lateral 
incisions, the larger polar lobe, and in the much stronger and more acute granules.

The nearest species to this is Euasiram spicatum, W. B. Turn., from which it is 
distinguished by the closed and very narrow sinus, and by the broad lateral lobes with retuse 
margins. ‘The lateral incisions on either side of the polar lobe are much deeper and not so 
open, and the spines, as well as being fewer in number, have quite a different arrangement. 
The central protuberance is also less granulate than in Æ. spicatum.

Hab. With the preceding species. 
The form of this species that we observed differed from that described by Turner in 
having a closed sinus and stronger less acute spines; moreover, the central protuberance 
possessed one ring of 7-9 subrectangular granules and a few central ones. On each 
side of the central protuberance and well within the lateral lobe is a smaller protuberance 
surmounted by about 3-5 short spines. This feature, which is especially noticeable in 
vertical view, does not appear to be present in typical E spicatum. We might have 
placed this plant with equal reason under E. ZHieronymusii, Schmidle, in Engler's Bot. 
Jahrbüch. xxvi. 1898, p. 42, t. 2. fig. 35. It seems to us to be a form which is 
intermediate between E. spicatum and E. Hieronymusii. It possesses the lateral lobes 
of the latter, but the slightly retuse polar lobe of the former species. The spines,
