GRAMINE^E. 235 



Uralepsis. Nutt. 3. 2. 

 U. aristulata. Nutt. Taken also from Aim. Glumes 2, 

 shorter than the florets, including 2-3 flowers; palese 2, very 

 unequal, villous on the margins ; florets standing on short stems 

 in the glumes ; panicle simple. The culms are cespitose or 

 growing in dense clusters, with axillary and terminal panicles, 

 scarcely extending beyond the sheaths ; sea-coast, and sandy 

 .fields ; New Bedford ; August. The plant secretes a viscid, sour 

 matter, of strong taste. Torrey. 



Kceleria. Pers. 3. 2. 



Glume 2-3-flowered, 2-valved, beardless ; valves shorter 

 than the lowest floret ; paleae 2 ; spikelets compressed. 



Named after Professor Koehler of Mayence, a writer on the 

 Grasses ; rather handsome plants. Loudon. 



K. Pennsylvanica. DC. Grows in rocky woods, 2 feet 

 high, with a long panicle, flat leaves, and soft, pubescent sheaths ; 

 May and June. 



K. truncata. Tor. Is 2 feet high, slender, with a branching 

 panicle, loose ; palese smooth ; dry woods ; June. 



Var. major. Tor. Has a large spreading panicle, and broad- 

 linear, long leaves. 



Both species taken from Aira, and not very abundant. 



Alopecurus. L. 3. 2. Fox-tail Grass. 



Named from the Greek for fox and tail, from the resemblance 

 -of its spike of flowers to the tail of that animal. The common 

 Timothy Grass has a similar appearance, and is often so called, 

 though its spike does not so much resemble the tail of a fox ; and 

 it is a very different plant, and should not trespass on the appro- 

 priate name of this plant. 



Only 3 species of Alopecurus are known in this country ; 

 A. pratensis, L., Meadow Fox-tail Grass, is found in rather more 

 wet situations than A. geniculates, L. ; both are somewhat pro- 

 cumbent. A. aristulatus, Mx., has very short awns ; grows 

 near Boston. They afford good food for cattle.
