 this species is essentially distinct from the following one.

A low-growing tree, again and again branched alternately, ulti- 

 mate branches 4-6 in. long, terete, slightly flexuous, stoutish, yel- 

 lowish, striolate, with axils |-f in. apart ; leaves rhomboidally 

 oblong, the terminal angle much longer than the two lateral ones, 

 cuneate at the base, the three angles sharply spinescent, rigidly cori- 

 aceous, very glabrous, generally plicate, above of a yellowish colour, 

 nearly concolorous beneath, inferior nerves ascending, the upper 

 nerves more patent, all arcuately conjoined within the margins, 

 with semi-immersed transversely reticulate veins, all with the 

 midrib prominulent and stoutish, 1^-2 in. long, 1|— 1£ in. broad, 

 including the lateral spines, on a plano-convex petiole 1-1| line 

 long ; inflorescence axillary, consisting of a bifid peduncle 3 lines 

 long, cinereo-velutinous, each branch bearing about 10 small con- 

 gested flowers about 1 line broad, with a construction detailed 

 in the generic character. 



I collected this plant in May 1825, making a drawing and an 

 analysis of its flowers in their living state during my stay there : 

 the plant is mentioned in my ' Travels,' i. p. 106.
