А very variable species in respect of the form and size of the leaves, presence or absence of spines, &e. 
In Col. Grant's plant the extremities are unarmed or with short slender spines: leaves broadly elliptical 
or obovate, obtuse or apiculate, 2-24 inches long, on petioles 3-$ inch, drying а pale ashen green. 
[Small tree, often met with, but rarely in fruit or flower: Тһе leaves are of a vivid green colour upon 
both sides, without gloss; their edges are sharp; when rubbed they smelllike fresh hay or sorrel, 
The upper parts of the stem and the petioles are pink. Spines in the axils of the leaves are pink ; but 
later, when below each branch, they become of a brown-grey colour. Calyx green; corolla white.
