6. STILLINGIA, Garden. 

 Flowers monoecious, in the axils of conspicuously 2-glandular bracts, in terminal 

 or rarely axillary spikes which are pistillate at base : involucre, petals and disk 

 none. Calyx imbricate in the bud ; the staniinate 2 - 3-cleft or 3-parted, the pistil- 

 late 3-parted or wanting Stamens 2 or 3, distinct or nearly so, central ; filaments 

 exserted ; anthers erect in the bud, with adnate rounded cells. Ovary 3-celled, 

 3-ovuled : styles 3, filiform, entire. Lobes of the capsule deciduous from a stout 

 horizontal 3-horned base [fn/nophore), often without a central column. Seeds 

 smooth or roughened, usually carunculate. Radicle equalling the broad cordate 

 cotyledons. — Smooth herbaceous or woody perennials, or some annual ; leaves 

 alternate, usually serrate, often 2-glandular at base ; pistillate ilowers solitary, the 

 staniinate 1 to 3 in each bract. — Miill. Arg. in DC. Prodr. xv''. 1155. Gymno- 

 stillingia, :Mu11. 1. c. 1163. 



Tbe genus as defined by Miiller inchides alwut a dozen widely scattered species, all perennials, 

 of wbicli two are found on the Atlantic coast, one of tbeni ranging west into New Mexico and 

 Nortbern Mexico. ]]i<i ^ennn Giiiunos/i/liiKjia, to wbicb tbe following species migbt be referred, 

 was founded upon two shrubby jilants of Mexico and Guatemala, but the cbaiacteis by which he 

 distinguishes it (the want of a calyx in the pistillate flowers, the solitary staniinate flowers, and 

 tbe ecarunculate seed) seem hardly sufficient for more than a sectional or subgeneric division. 

 The closely allied Schasfiania, Spreng., is distinguislied cliiefly by the absence of the gynophore. 



* Perennials: spikes fermiiial: leaves narrow, entire or neartt/ so. 



1. S. linearifolia, Watson. Herbaceous, bmnching from the somewhat woody 

 base, a foot higii or more: stems and branches slender, terete, ascending: leaves 

 linear, entire, or rarely very obscurely glandular-toothed, acute, a half to an inch 

 long : spikes very slender, open, 1 to H inches long, with 2 to 7 scattered pistillate 

 ilowers below : bracts very small, ovate, acute, minutely glandular on each side, 

 I -(lowered : staniinate fiowers very small; calyx turbinate: stamens 2: pistillate 

 calyx none : capsule li lines in diameter; the horns of the gynophore rather tliin, 

 and central column often persistent : .seed round-ovato, acute, a lino long, smooth, 

 somewhat viscid, not carunculate. — Proc. Amer. Acad. xiv. 297.

2. S. paucidentata, Watson. Herbaceous, the stout angled stems branching 

 above : leaves linear, acuminate, an inch or two long with 2 or 3 setaceous teeth ou 

 each side usually near the base : spikes slender, but stouter and denser than in the 

 last, with similar bracts and fiowers ; the pistillate fiowers more crowded : capsule 

 2 lines in diameter, with very prominent gynophore : seeds IJ lines long, oblong- 

 ovate, acute and slightly carunculate, smooth. — Proc. Amer. Acad. xiv. 298.
