I can find no specific distinction between the type specimens of E. platycephala

54. E. Monteiri, Hook. f. in Bot. Mag. t. 5534. Perennial. 
Primary stem about 1 ft. high and up to 13 in. (or perhaps more) in 
thickness, cylindric, tuberculate with the conical persistent leaf-bases, 
simple or with a few similar branches, fleshy, glabrous, leafy only at the 
apex, naked below, described as resembling “an old cabbage-stump, 
producing around the apex annual deciduous leafy flowering-branches 
6-12 lin. long_and 14-24 lin. thick, erect, terete, not tuberculate, 
glabrous, glaucous-green. Leaves all alternate, 2-6 in. long, {-1j in. 
broad ; those on the fleshy stems linear to spathulate-oblong, obtuse or

the middle into a petiole 1-4 in. long; those on the flowering branches 
‘sessile or very shortly petiolate, narrowly lanceolate or linear-oblong, 
acute or obtuse, apiculate, shortly cuneate at the base, or occ 
sionally like those on the fleshy stems, all glabrous on both sides, 
glaucous-green. Stipules none. Cyme terminal, umbel-like, 2-3- 
rayed, sometimes accompanied by solitary rays in the axils of the 
leaves below; rays at first 14-34 in. long, ultimately developing into 
dichotomous cymes up to 8 in. long. Bracts opposite, or those at the 
base of the umbel-like cyme 3 in a whorl, 3-24 in. lorg, $-1} in. broad, 
sessile, cordate-ovate, acute or tapering to a long point, glabrous.
