Setaria rariflora Presl, Rel. Haenk. 1: 313. 1830. Not Setaria rariflora Mikan, 

 1821. "Hab. ad Acapulco." The type, in the herbarium of the German University 

 at Prague, is the small form like 

 the variety pauciflora . 1 1 is labeled 

 "Mexico. H."

Setaria liebmanni Fourn. Mex. 

 PI. 2: 44. 1886. "Manantial, au- 

 gusto (Liebm. n. 389)." The type 

 specimen, in the Copenhagen 

 Herbarium, consists of a culm with 

 several broad blades and a panicle 

 about 20 cm. long from which most 

 of the spikelets have fallen. The 

 label reads, "PI. Mexic. Liebm. 

 Gramineae n. 389. S. Liebmanni 

 (scripsit Fournier) Manantial. 

 8/41." The locality is uncertain, 

 but it must be in Veracruz since 

 Liebmann did not go outside of 

 that state during 1841.

 collection, is a small formjwith blades 5 to 7 mm. wide, and panicles 5 to 9 cm. 

 long, narrow, few-flowered, the branches mostly not over 5 mm. long, a few as much 

 as 1 cm. long.
