Puccinia panicicola sp. nov.

II. Uredinia amphigenous, numerous, scattered, oval, 0.1-0.3 
mm. wide by 0.2-0.4 mm. long, soon naked, pulverulent, dark 
cinnamon-brown, ruptured epidermis noticeable; urediniospores

III. Telia not seen. 
On Panicum molle Sw., Santiago de las Vegas, Cuba, March 
I, 1907 (type), March 6, 1903, C. F Baker; Cuautla, State of.

smaller, more strongly sculptured, and have thinner walls with 
fewer pores.
