Andropogon foveolatus, Del. 



The stems are slender at first, slightly decumbent at the base 

 and then erect, covered at base with silkily villous sheaths, branches 

 freely above before flowering, the lower portion of stems alone 

 being leafy. 



The leaf-sheath is somewhat scaberulous, partly green and partly 

 purplish, always shorter than the internode. The ligule is short, 

 truncate, hyaline and ciliate. Nodes are tumid and purplish with 

 a ring of hairs. 



The leaf-blade is linear, narrow, sometimes even filiform, 

 acuminate slightly cordate at the base, scabrid throughout with 

 a few scattered long bulbous-based hairs near the base to a 

 distance of less than Y 2 inch about it and varies from 2 to 4 

 inches in length.

I and 2. Sessile and pedicelled spikelets ; 3, 4, 5 and 6. the first, second, third 

 and the fourth glume, respectively, of the sessile spikelet ; 7. lodicules, anthers and ovary; 

 8, 9 and 10. the two glumes and the palea of the pedicelled spikelet. 



The spikes are solitary, I to 1% inch long exserted far above the 

 small spathiform leaf-sheaths, peduncles are capillary and scab- 

 erulous, pedicels and joints are somewhat flattened, and have along 

 both the narrow margins long, white, ascending hairs ; callus is 

 short with a ring of short white hairs. 



There are two kinds of spikelets, sessile and pedicelled, and both 

 are oblong-lanceolate and equal. The sessile spikelet consists of four
