ing or producing distinct stolons; 

 sheaths compressed, strongly keeled, 

 usually 2 to 4 aggregate below; blades 



3 to 8 mm. wide, often short and nu- 

 merous on the stolons; spikes mostly 



4 to 6, 4 to 10 cm. long; spikelets 2 

 mm. long; lemma mucronate, short- 

 ciliate on the nerves. 91 (Eustachys 

 petraea Desv.) — Strands, sandy fields, 

 and open pine woods, Coastal Plain, 

 North Carolina to Florida and Texas; 

 tropical America. 



3. Chloris floridana (Chapm.) 

 Wood. (Fig. 758.) Culms slender, 40 

 to 80 cm. tall; sheaths compressed, 

 crowded at base but not paired or ag- 

 gregate at succeeding nodes; blades 3 

 to 7 mm. wide, somewhat narrowed 

 toward the acutish tip; spikes mostly 

 2, sometimes 1 or 3, 5 to 10 cm. long; 

 spikelets 3 mm. long; second glume 

 with an awn about 1 mm. long; lemma 

 with a slender mucro 0.5 to 1 mm. 



long, stiffly ciliate on keel and lateral 

 nerves. % {Eustachys floridana 

 Chapm.) — Dry sandy woods and 

 open ground, Georgia and Florida. 



4. Chloris neglecta Nash. (Fig. 

 759.) Differing from C. floridana in 

 having usually taller, stouter culms, 

 the leaves sometimes paired at the 

 lower nodes; spikes 3 to 8, mostly 4 

 to 6. % (Eustachys neglecta Nash.) 

 — Open sandy woods and swamps, 

 Florida. 



Chloris distichophylla Lag. Culms 

 about 1 m. tall; spikes several (as 

 many as 20), drooping, feathery; 

 lemma ciliate with silky hairs 1 mm. 

 long. % — Escaped from cultiva- 

 tion in southern California. A speci- 

 men from Bastrop, Tex., is probably 

 also an escape from cultivation; South 

 America.
