A member of the nictitans group but remarkable for its erect habit 

 and sessile petiolar gland. I take pleasure in dedicating the species 

 to Dr. Millspaugh, who has very kindly permitted me to determine 

 the large and interesting collection of Cassia and Chamaecrista col- 

 lected by him in the West Indies.

HvEmatoxylon Campechianum Linn. Sp. PI. 384. 



Plentifully planted as a hedge in the suburbs of San Domingo 

 city (822, 824), largely introduced into Jamaica and Grand Cayman 

 (1369, 1 371) where it is now scattered all over the interior of the latter 

 island forming, with Psidium Guajava, the main portion of the 

 "brush" with which the old lands and fields are so heavily clothed.
