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 E. pilosa (L.) Beauv., but the spikelets are larger and 

 broader.

Spikelets 15 mm, or more long, 7 to 10 mm. wide 1. U. paniculata. 



Spikelets 2 to 3 mm. long, 1 to 2 mm. wide 2. U. virgata.

 Wright 2823 [error for 3823]. 



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.
