Type in the U. S. National Herbarium, No. 1,145,291, col- 

 lected on banks of the Yara River, Oriente, August 14, 1922 

 (E. L. Ekman 14852). 



Related to R. calophylla Standley,* but evidently distinct

 in July, 1922, by Brother Leon. Dr. Ekman also obtained it in 

 August, 1922, at Arroyo Corojo, Nagua, Oriente (No. 14729).

KaUstr.oemiu cariba< rban, Symb. Ant. 8:319. 1920. Not 

 K. caribaea Rydberg, 1910. 



A diffusely branched herb, somewli.it woody at the base; 

 stems spreading, 2-3 dm. long, with coarser spreading and finer 

 more appressecl hairs, terete; stipules linear-oblong, 2-3 mm. 

 long, tardily deciduous; leaves I 1.5 cm. long; petioles 2-3 mm.

 Fuertes 418 (herbarium of the New York Botanical Garden); 

 also collected at Rincon, October 191 1, Fuertes 1352. 



The two numbers cited were determined by Urban as K. 

 caribaea and included under that name in his Flora Domingensis, 

 but it differs in the hoary pubescence, the small leaflets, the small 

 petals, scarcely half as long as in K. caribaea, the short peduncles 

 and short beak on the small fruit. It approaches more K. carta 

 Rydberg, from ( "uracao.w it h which it has the following characters 

 in common: small leaflets, short peduncles, small petals ami 

 fruit, and short beak; but it is more canescenl, more branched, 

 with shorterinternodes and smaller lea\ es.and the beak different, 

 not at all swollen.
