Type in the IT. S. National Herbarium, No. 1,114,896, collected in 

 pine forests at Hacienda Monserrate, Chiapas, September, 1923 ; 

 Purpus No. 9246. Closely related to S. purpurata Blake, of Jalisco, 

 which has the leaflets conspicuously pilose-setose on the margin, and 

 fruit with a terminal style. In S. eciliata the leaflets are weakly pilose- 

 ciliate, and the style is borne slightly below the level of the rounded 

 highest point of the fruit, so that it appears to be lateral.
