107. E. spartaria, V. £2. Br. A succulent leafless shrub 3 ft. high, 
dichotomously or trichotomously branched. Stems or main branches 
4-1 in. thick, with lateral suberect branches often 1 ft. or more long and 
31 lin. thick, flowering branchlets 4—2 lin. thick, all articulated at their 
origin, terete, ending in 2-4 times forked cymes, glabrous. Leaves

deciduous, 1-1} lin. long, }-} lin. broad, spathulate, with the dilated 
‘part transversely rhomboid to suborbicular, very obtuse, often apiculate,

deep, scarcely narrowed to the base, cup-shaped; of the female plant 
2 lin. deep, distinctly narrowed to the base, funnel-shaped, glabrous

verse ciliate lobes; glands }—2 lin. in their greater diam., transversely 
oblong,entire. Ovary nearly exserted from the involucre, erect, 3-angled, 
glabrous ; styles 4 lin. long, stout, united for half their length and rising

and seeds not seen.

This is closely allied to E. ephedroides, E. Meyer, of South Africa, and evidently 
the tropical representative of it, but the main branches seem to be longer, straighter 
and rather stouter, giving the plant a different appearance and the styles are not free 
and spreading directly from their base as they do in E, ephedroides.
