Root fibrous, not creeping. Stems several, a foot high, round, 

 leafy j decumbent at the base. Whole plant slightly glaucous, 

 smooth. Leaves tapering to a sharp point. Stipula rather short, 

 obtuse, notched ; that of the upper leaves often pointed. Panicle 

 erect, with several series of half-whorled, angular, slender, rough 

 branches, rigidly bent downward in a very remarkable m';inner. 

 Spikelets linear, while young somewhat elliptical, variegated 

 with purple. Florets smooth and shining, rarely more than 5, 

 slightly distant. Outer valve of the corolla quite cylindrical, 

 without any keel, but marked with 5 blunt, more or less evi- 

 dent, ribs, which are commonly purple, and the interstices glau- 

 cous ; the point is abrupt and membranous j inner valve slightly 

 notched. Nectary deeply cloven. Styles short. Stigmas large 

 and densely feathery j according to Mr. Curtis "branched."

G. caninum maritimum paniculatum. lb. 410. 



In salt marshes on the coast, frequent. 



Perennial. July — Oct. 



Root creeping, by which it differs essentially from the last. Herbage 

 more glaucous. Leaves involute, sharp-pointed, with rather 

 tumid sheaths and a short stipula. Branches of the panicle 

 spreading whilst in flower, then erect, rarely divaricated, never 

 deflexed. Florets quite cylindrical, rather pointed, but not con- 

 stantly so, their five ribs less evident than in the last-described.
