TRIANDRfA. DIGYXIA. 77 



erec!, vaUes linear, subulate, awiiiess, each with a single 

 nerve, larger than tlie flosculi; corolla valves, small, ovate, 

 obtuse, smooth, the outer o-nerved, the inner 2. Stamens 

 and styles very short, purple. 



On the banks of the Missisippi, near Xew Orleans. 



This is probably the Eleusiiie 7nucro7iata of Mr. Elliott; 

 but he remarks that tiie glumes of the corolla are hairy, 

 and the stipules beaiikd, neither of which particulars ap- 

 pear to exist in the present plant. As the valves of the ca- 

 lix are not mucionaie it cannot but be improper to apply 

 Michaux's name to this species, which may be probably 

 distinct. To this genus belongs the E'eufiiiie JiUformi-s of 

 Persoon, growing in ihe tropical regions of America, and 

 nearly allied to the present species, having also the same 

 kind of glandular pubescence, and we may probably add 

 the Eicusine vivgata of Jamaica. 



109. CllLORIS. Sivartx. 



Flowers poIyganKjiis. Spikes di^^itate, iini- 

 laterai. — Calix S-valved, 2 to 4-llowered; valves 

 carinate, with or without an awn: (flowers dis- 

 similar, the aborcive llorets pedicellate.) 



The habit of this genus is similar to Eleushie, but the 

 ft-i tile flowers, particularly in C. pefnea are coriaceous, 

 and gibbouslv carinated, so as to appear transversely seat- 

 ed in the calix; the fiower glum.es when in seed, greatly 

 exceed the calix in Lngth, and are of a dark brown co- 

 lour, the heruiaphiofiite terminated by a shoi-t cusp, tlie 

 neuter or male flower being inflated and obtuse, like the 

 rudiment in J\ielica; the outer valve of the calix from its 

 eniargmation, has a cuneate obcordate appearance, with 

 the n iddle neive terminated by a short awn; the seed is 

 naked, triquetrous, and smooth. 



Spfcies. 1. C pett'ita. 2. mitcronata. In this species 

 tlie fiovvvrs are a^so transversely seated in the calix, but 

 not distinctly coriaceous; the seed is very unequally 3- 

 sided, scabrous, naked, and compressed. This structure 

 oftl-.esefd appears to indicate some ainnuy to Eleusine 

 Indica, but the habit is widely distinct. 



110. ATHEROPOGON. Muhknhcrg, 

 Flowers polygamous, in unilateral spikes. — 



Calix 2-valved, 2-fl'»wered, inner valve almost 

 setitbrm. Hermaphrodite corolla 2-valved, ex-
