6(3 PHANEROGAMIA. 



Hab. Oahu, Sandwich Islands ; on the coast near Honolulu. Also 

 gathered by Lay and Collie, Barclay, and Meyen. 



Plant herbaceous, clothed with a viscous pubescence ; the stem, petioles, 

 and midrib of the leaflets sparsely aculeate with small and weak 

 prickles; the stipular ones stronger. Cauline leaves of 5 leaflets, 

 which are oblong-lanceolate, one to 2i inches long, and cinereous on 

 both surfaces with a short and close viscid pubescence. Floral leaves 

 ovate, slightly cordate, small, on short petioles, shorter than the very 

 pubescent and somewhat setose-hispid viscous pedicels. Calyx hairy 

 and viscous like the pedicels. Petals apparently white, 3 lines long, 

 obovate-oblong, on short claws. Pod 1J to 2 inches long, about 2 

 lines in diameter, smooth and glabrous, terete, crowned with a thick 

 subsessile stigma, raised on a filiform glabrous stipe (the carpophore) of 

 its own length, or very little shorter. 



This species is certainly to be distinguished from Cleome spinosa 

 (with which it has been confounded), by its pubescent leaves, and the 

 proportionally longer stipe; as long as the pod itself in most specimens 

 that I have seen, or a little shorter in the single specimen in the col- 

 lection of the Exploring Expedition. The pod is only half the length 

 of that of O. pungens.

Hab. Above Obrajillo, Andes of Peru : common. 



Accords well with the figure in Delessert's Icones, or perhaps with 

 the pruinose-glandular pods a little shorter. The calyx is persistent 

 in one of the specimens, but deciduous in the other. 



3. Cleome diffusa, Banlcs, in DC. I. c. 

 Hab. Rio Janeiro, Brazil : common in open places.
