 ^fein stem 5-7 lines t ick, branches 3-4-| lines thick, with inter- 

 nodes f-l inch long, and more or less thickened at the nodes, glab- 

 rous, brovm under cultivation, nale grey v;hen imported. United

 base, thence gradually tapering to a sub-obtuse apex, channelled 

 down the face, obtusely keeled dovm the back; the free leaves s-ls 

 inch long, 3-4 lines broad at the base, thence tapering to a sub-

 p. 182. — A shrublet 10-lS inches high. Stems and branches 3-7 

 lines thick, v/ith internodes 5-13 lines long; and constricted at 

 the nodes, glabrous, at first green or reddish-brovm, becoming 

 pale grey with age. United pairs of leaves forming cylindric bod-

 ending in a pair of horizontally spreading or recurving leafy tips 

 1-2 inches long and 2-3 lines broad at the base; the free leaves 

 i-2 inches long, 3-5 lines broad and 3-4 lines thick at the base, 

 thence tapering to a sub-obtuse point, slightly concave above, 

 obtusely keeled beneath; all v/hen young covered with minute, glit- 

 tering, v/atery papulae, those on the keel and edges larger than the
