Described from a small branch and some fruiting cymes, accompanied by an 
excellent photograph. Besides the difference in the branches, the long cyme-peduncles 
and small.fruit readily distinguish this from its allies. 
170. BE. grandis, Lem. /ll. [/ort. iv. Miscell. 101, 107. Arborescent, 
15-20 (or probably more) ft. high, leafless, spiny. Branches fleshy, 
usually whorled, curved-ascending or suberect, usually 6- (sometimes 5-) 
angled, 3-8 in. in diam. and 1-5 in. from angle to angle, constricted 
into elliptic or more or less conical joints mostly 3-8 but sometimes up 
to 18 in. long, glabrous, deep green; angles wing-like, with triangular 
or ultimately broadly concave channels 3-14 in. deep between them, 
even or very faintly sinuate-toothed along the margins. Leaves rudi- 
mentary, scale-like, 1-1} lin. long, deltoid-ovate, acute, with smaller 
obtuse scale-like stipules at their base, soon deciduous. Spines usually 
1-3 lin. long, sometimes nearly obsolete, in pairs 5-11 lin. apart, 
diverging, on rhomboid-orbicular or rhomboid-ovate horny shields 2-3 
lin. long and 2-23 lin. broad, both spines and shields at first green, 
becoming light rusty-brown and finally grey. Flowering-eyes touch- 
ing the apex of the shields. Flowers and fruit not seen.—Z. abys-

the tips of the branches, nearly sessile, about 23 lin. in diam., cup-shaped, 
with 5 contiguous transverse entire glands. :
