Prosopis 



A species of Prosopis is common about Honolulu, nourishing 

 best in hot, dry situations, and having the same range as Acacia 

 farnesiana. By Hillebrand it is said to be' " Prosopis juliflora 

 DC. or P. dulcis, Kunth." It is certainly very distinct from the 

 species called juliflora in the southwestern part of the United 

 States, although it has a similar pod. The leaflets are short 

 and pubescent, as compared with the long, smooth ones of the 

 American plant. P. dulcis Kunth, is described as having a 

 torulose pod, which forbids its being a synonym of P. juliflora.

CAESALPINIACEAE. 

 CAESALPINIA L. Sp. PL 380. 1753, 

 Caesalpinia bonduc (L.) Roxb. Hort. Beng. 32. 1814. 



Guilandina bonduc L. Sp. PI. 381. 1753. 



Hillebrand unites this with Caesalpinia bonducella Even 

 the most casual examination of dried specimens shows that the 

 two are abundantly distinct. As opposed to bonducella, the 

 branches are more climbing, glabrous, armed with fewer, 

 shorter, and straighter prickles. The leaves are broader, 

 blunter, and smooth. The inflorescence is naked, and the flowers 

 fewer and much larger. It seems to be rare on the islands. 

 A single vine, for it grows much like a grape vine, was found 

 climbing over the limbs of a fallen Koa tree, on the main ridge 

 west of the Hanapepe river, Kauai, at an elevation of about 

 2500 feet.

Caesalpinia bonducella (L. ) Fleming, As. Res. 11: 159. 1810. 



Guilandina bonducella L. Sp. PI. Ed. 2. 545. 1763. 



In the valley of the Hanapepe river, Kauai, this species is 

 -common. In habit it is trailing rather than climbing. The 

 stems are numerous, twining and interlacing, so as to form an 

 impenetrable clump three or four feet high. The stems and 

 branches are pubescent, with short, tawny hairs, and provided 

 with numerous prickles, which curve downward. The leaf- 

 lets are comparatively narrow, acute, and pubescent beneath. 

 The inflorescence is heavily bracted, the flowers small and 

 crowded.
