C. megarrhiza, Parry. Root very large (inch or two thick, often a foot long), conical or 

 fusiform : radical leaves spatulate to dilated-cuueate, 2 to G inciies long including tlie long 

 wiug-petioled base, ecjualliug or surpassing the cyniosely fe\v-several-Ho\vered scapes ; tiiese 

 bearing mostly two or rarely more alternate spatulate to linear leaves tapering below as if 

 petioled, or occasionally opposite, or reduced to scarious bracts. — Parry in Wats. Bibl. Index,

* * * Subterranean stems (whether cormatose or caudicose) unknown : cauline leaves sub- 

 opposite, narrow : pedicels elongated, the lowest subtended by a short relatively broad ovate- 

 lanceolate bract : sepals unequal, narrow and attenuate. 

 C* Bodini, Holzinger. Slender .stems 4 to 6 inches high, mostly 2-leaved below the middle : 

 leaves narrowly linear, unequal, about 2 to 3 inches in length, a line or less in breadth •. lower 

 pedicels 1^ to 2 inches long : calyx spathaceous; the lanceolate attenuate sepals 4 to 5 lines

§ 1. Rhizomatose ; the flowering stems, bearing a pair of broad sessile leaves 

 below the racemiform mostly bractless inflorescence, and the long-petioled radical 

 leaves from creeping little-thickened rootstocks : petals obovate and emarginate 

 or obcordate, rose-color or white : pedicels in fruit erect or ascending. 



M.* sarmentosa, Rorinson, n. comb. About a span high from creeping filiform rootstocks 

 or stolons moderately thickened at the crown : radical leaves obovate-spatulate, mostly obtuse, 

 half inch or more long, abruptly contracted into a longer petiole with no scarious dilated 

 base ; cauline ovate or orbicular, closely sessile : flowers few : petals broadly obovate, emar- 

 ginate, a third to half inch long, 3 or 4 times the length of the sepals. — Cla>/to)7)a sarmen-
