There is a great approximation of characters between this and 
the two preceding species, and more especially with the latter, the 
principal difference consisting in its ovary, which is represented 
as being 3-locular, — a difference which it must be remembered 
exists also in Trevoa. Contumasay, where it is found, is scarcely 
4° south of Guayaquil. Its branchlets are glaucous, and obso- 
letely pubescent, as well as sub-4- gonous; its spines are hori- 
zontal and opposite, sometimes a little alternate, and from 10 to 
20 lines long; its leaves are said to be not quite an inch long, 
on a petiole 1 line in length, but they are now wanting in the 
specimen. Kunth observes that the leaves are very deciduous, 
and that the specimen he examined was almost aphyllous, look- 
ing quite like a Colletia ; the same may be said of S. pauciflora. 
The floriferous branchlets are about the length of the spines, 
spring from below them, and are more slender and flexible : the 
flowers (1 or 2) are sessile in the opposite axils of the nodes, 
which are about a line apart ; they are very minute, scarcely 
more than a half-line in length and the same in diameter*.
