166 CONTRIBUTIONS FROM THE NATIONAL HERBAEILTM, 



The five Porto Ilican species of this genus belong to four different sections. C, 

 bonduc and C. crista are included in section 1, Guilandina. They are aculeate, 

 scandent shrubs with membranous leaflets and echinate legumes, 



C. sepiaria belongs to section 3, Sappania. It is a prickly climbing shrub with 

 seeds that are as long as widCj and glabrous legumes. 



C. pulcherrima, a shrub with beautiful fragrant flowert^s, is contained in section 4, 

 Caesalpinaria. The long-exserted anthers and small membranous leaflets are also 

 noticeable. 



C. gilliesii, worthy of notice on account of its minute leaflets and lanceolate 

 legumes, is included in section G, Erythrostemon.

Every part of the plant (root, leaves, seeds, bark) is valuable medicinally. There 

 appears to be a difference of opinion regarding the properties of the roots, but all 

 authors agree in extolling the virtues of the seed. For making bracelets, necklaces, 

 and rosaries the seeds are much used, and in some countries the children use them

for marbles.
