Mr. Baker (Journ. Linn. Soc. lc.) regards A. scaber, 
Lowe, as a variety of A. umbellatus, but Webb and 
Berthelot do not; and I fail to find sufficient characters 
whereby to distinguish it. The cladodes attain a greater 
length under cultivation than I find them to be in any 
specimens preserved in the Kew Herbarium. 
Descr. — Stem slender, climbing, woody and _ terete 
below ; branches flexuous, drooping, angled and grooved ; 
internodes short, angles of the branchlets minutely 
scaberulous. Leaves minute, deltoid, or 0. Cladodes in

or filiform, tips rounded or pungent, terete, or obscurely 
angled, smooth or sparsely scaberulous, very dark green. 
Flowers three to six in an umbel at the tips of the branch- 
lets, with often a few axillary in the fascicles of the cladodes, 
white; pedicels one-third to half an inch long, jointed 
considerably below the middle; bracts minute. Perianth 
- campanulate ; segments narrowly oblong, obtuse, recurved, 
one-third of an inch long. Filaments inserted above the

black—J. D. H.
