Fructus niger, 3 mm. longus, baccatus, quinque-carpel- 
latus. 
Saurauia Comitis- Rosset appears to have no close allies 
among the known species of Mexico and adjacent parts 
of Middle America. It is easily distinguished by its ex- 
tremely thick and coriaceous leaves, as well as by a num- 
ber of less conspicuous vegetative and floral characters. 
The common name of Saurauia Comitis-Rossei is re- 
ported by Reko to be “‘mameyito.’’ In southern Mexico, 
this name refers to a number of species of Saurauia and 
other genera with small, edible fruits. 
At the request of the collector, I have named Saurauia 
Comitis- Rosset in honor of the Earl of Rosse in recogni- 
tion of his active and enthusiastic interest in Mexican 
horticulture.
