i70 TRIANDRIA D! GYNTA, 



Root annual. Stem 6—12 inches long, erect, geniculate near U 

 foot, columnar, glabrous. Leaves 2 — 3 uiclies long, subulate, concave, 

 not keeled, glabrous on the under surface, scabrous on the upper, and 

 along the margins ; sheaths nearly as long as flie joints ; stipules mem. 

 branous. Panic te equal, not seciind. Spikes 4— 7-flo\vered, nearly 

 sessile. Calyx '■Z valved, valves unequal, very small, linear-Ianceoiite, 

 ac^te. Corolla 2 valved; exterior valve concave, hairy, particularly 

 near the summit, terminating in an awn twice as long as the valve; the 

 interior valve membranous, lanceolare, unawned,with the back impress- 

 ed, as is the case in all spikes with distichous flowers. Filament ouei 

 scarcely longer than tlie germ. Str/les 3, yery short. Stigmas plu* 

 mose, white. Seed oblong acute. 



^ Of this plant, as of theT. tenella, Ihave never seen the stamens or 

 pistils uncovered by the corolla, yet I have no doubt but that at some 

 particular hour, or in some peculiar temperature, these organs are ei» 

 posed to the influence of the atmosphere. 



I once considered this plant as distinct from the Linnsean F. mpr- 

 us, and named it F. monandra; the description however of Lamarck 

 in the Encyclopedie Methodique renders it probable that it is the same: 

 the only circumstances which still occasion any doubt, the hairy coroN 

 la and solitary filaments, are omitted in his description. 

 Grows in very dry soils.

Hoot fibroug, perennial. Stem i2 — 18 inches high, slender, gli^* 

 brous. Leaves linear, almost filiform, 5—4 inches long, slightly sca- 

 brous? shcatfis nearly as long as the joints; stipule membranous, trun- 

 cate. Spikes terete", tapering to tne summit but not compressed** 

 in F. tenella. Valves of the calyx unequal, very acute; keel serru- 

 late. Exterior valve of the corolla terminjitin- in an awn ab<?«t •' 

 own length; interior valve small lanceolate, with the margin slig'HiJ 

 reflexed. Styles very short. Stigmas feathered, white. 



Near to F. spicata, Pursh. The upper or interior Horets are sn^J 

 ter at first than the exterior by which they appear to be envelope f 

 but gradually extend with age.
