*Paiiicum capillare L., var. flexile Gattinger, is either one of the 

 forms of P. capillare, or an annual variety of P. autumnale Rascoe, 

 which it resembles greatly, especially in smoothness and form of 

 spikelets. It is very smooth above, with some hairs on the lower part 

 of culm and leaves; culm very slender, panicle rather small, and 

 branches not spreading until the mature spikelets are ready to drop 

 off; leaves linear, gradually attenuate, of a pale green color. It abounds 

 in the cedar glades, and is rarely seen outside of them.
