Cenchrus Palmeri Vasey. Culm 9 to 18 inches high, 

 flattened below, branching, leafy: leaves puberulent, es- 

 pecially the inflated, conduplicate sheaths which are 

 ciliate on the margins, and with a ligule of rather long 

 white hairs; sheaths mostly as long as the internodes; 

 blade lanceolate - linear, 4-6 inches long. Spikes con- 

 sisting of 2 to 4, usually 3, large, roundish, closely ap- 

 proximate, purple spikelets, 1 to Ih inches in diameter, 

 including the spines, these are flattened toward the base, 

 the upper part slender, the longest 6-8 lines long, diminin- 

 ishing to the broad base, where a few are much smaller, 

 but there are no proper bristles. The base of the spines 

 and the body of the spikelets are closely pubescent. Each 

 spikelet contains 5 or 6 flowers. 



First collected by Dr. E. Palmer at Guaymas, Mex., in 

 1887, in company with a yellow-colored variety. The 

 present specimens are a young and small form, with the 

 spikelet half as large as the type, but otherwise the same. 

 Possibly it may be a distinct variety. — Common through- 

 out the southern part of the peninsula.
