The Grisebach specimen is from Wright, 1860-64, without number. In the Gray 
Herbarium is a Wright specimen without number, with an 1860-64 label, and two 
specimens numbered 745 from eastern Cuba, one collected in 1856-57, the other 
in 1859. 
This species is similar to FE. pilosa (L.) Beauv., but the spikelets are larger and 
broader.

The Grisebach specimen is labeled ‘Sandy sea-beach, Cananova, July 15,”’ no. 
280, 1865. In Sauvalle’s Flora Cubana this is numbered 3823, which is apparently 
correct. The specimen in the Gray Herbarium is numbered 3823.
