 quibo, where the pounded stem is used for poisoning fish under the name of 

 Bastard Hiarry. Schomburgk, n. 52. 



The genus Loncho carpus, though numerous in species, and some 

 of them common in tropical America, is as yet so imperfectly known 

 that it is not easy to trace its immediate affinities. It appears to 

 connect the Galegece with the Dalbergiece. The flowers are very nearly 

 those of Tephrosia and Robinia, in which latter genus the early 

 writers comprehended many of the species, but the pod is said, in 

 most cases where it is known, to be indehiscent. If this be really 

 the case it should probably be removed to Dalbergieac. Among the 

 supposed species of Lonchocarpus the L. Amerimnum seems to be a 

 Platymiscium, and Kunth's genus Clyciridia should perhaps be 

 adopted for the L. sepium. The L. violaceus and L. punctatus are 

 remarkable from the mixture of round and oblong glandular dots in 

 their leaves, and form a separate section if not a genus. The three 

 new species enumerated above differ from most others by their inflo- 

 rescence, which is that of many Phaseole<e, but the flowers are pre- 

 cisely those of Lonchocarpus, and in the absence of the fruit it does 

 not appear advisable to separate them.
