12 Britton: Studies of West Indian plants 



29. Chamaecrista Chamaecrista (L.) 



Cassia Chamaecrista L. Sp. PI. 379. 1753. 



Cassia diffusa DC. Mem. Soc. Hist. Nat. Gen. 2: 130. 1824. 



Cassia smaragdina Macf. Fl. Jam. 1: 347. 1837. 



Chamaecrista diffusa Britton, Ann. Missouri Bot. Gard. 2: 41. 



I9I5- 



Type locality : Curacao. 



Distribution: Bahamas; Jamaica; Cuba; ? Hispaniola; Porto 

 Rico; St. Jan; St. Croix; St. Kitts; Guadeloupe; Grenada; Curacao; 

 Margarita. 



Illustrations: Breyn, pi. 24; Schrank, Hort. Monac. pi. 33. 



The species has been much confused with the annual C. 

 nictitans of eastern continental North America. 



The recognition of the plant of Curacao as typical Cassia 

 Chamaecrista brings C. diffusa into its synonymy.
