93, E. sepium, V. Z. Br. A shrub. Branches terete, forking, 
glabrous, perhaps subfleshy at the young parts, 3-3 lin. thick in the

long, broadly and shallowly cup-shaped, 3-34 lin. in diam., minutely 
puberulous outside, glabrous within, with 5 glands and 5 transversely 
rectangular fringed lobes; glands 1-1} lin. broad in their greater 
diam., transversely oblong or elliptic, entire, yellow. Ovary (immature)

J4. E. Rogeri, V.#. Br. A much-branched shrub, woody below, 
succulent at the younger parts, naked, bearing leaves at the ends of the 
young branches only, without spines, glabrous. Stems or main branches

the involucre, 4 in. in diam., subglobose, pubescent ; styles not seen. 
Seeds (immature) globose, 14 lin. in diam., smooth.
