?Cassia stricta Schrank, Hort. Monac. i: pi. 34. 1819. 

 Chamaecrista virgata Greene, Pittonia 4:31. 1899. 



Type locality : Jamaica. 



Distribution: Jamaica. 



Illustrations: Bot. Mag. pi. 3435; Schrank, loc. cit. 



Linnaeus included, in his citations of synonyms of this species, 

 several others, but his description of it, together with his having 

 received a Jamaica specimen from the collection of Patrick Browne, 

 prior to his publication, as I am informed by Dr. B. Daydon 

 Jackson, Secretary of the Linnaean Society of London, show that 

 the name is to be restricted to the Jamaica plant. Subsequent 

 authors have confused it with species from other islands and from 

 continental tropical America. The identity of Cassia virgata Sw. 

 was established for me by Mr. William Fawcett at the British 

 Museum of Natural History. Cassia stricta Schrank, from the 

 illustration and the Jamaica habitat, appears referable here, but 

 Schrank's description of the plant is not altogether conclusive; 

 he says the root is annual.
