IV. DESCRIPTIONS OF NEW SPERMATOPHYTES, 
CHIEFLY FROM THE COLLECTIONS oF g 
PROF. M. E. PECK IN BRITISH HONDURAS. 
By S. F. Buake. 
The new species here described, belonging for the most part to 
sympetalous orders, are based mainly on the extensive collections 
made by Prof. M. E. Peck in British Honduras from 1905 to 1907. 
A few other species are described from hitherto undetermined collec- 
tions made in Mexico, Costa Rica, and Nicaragua by C. F. suas 
Langlassé, Palmer, Pringle, Rose, and Tonduz. A new species : 
Danthonia from Mexico, described at the Gray Herbarium by
