Ctenium Chapadense Doell, Mart. Fl. Bras. 2: Part 3, 7 3. 1878. 
This plant was found growing plentifully by the writer this 
Summer in the flat woods at Lake City, Florida, no. 2212. A. H. 
Curtiss collected the same in East Florida in 1875; his no. 4058 
also appears to be this plant. It was also secured by Fredholm 
in Duval Co., Fla., in 1893, no. 313. : 
It differs from C. aromatica (Walt.) Scribn. (Ctenium —"* 
canum Spreng.) in its more slender habit and narrower spikes ; 
smaller spikelets divergent from the rachis, not oe the 
Scales narrower and very acute; the awns more delicate and much 
longer.
