* Tj^icdl Claytonia. (Spring Beauty.) Cor mose ; the slender 2-leaved stems and sparse 

 and few radical leaves (rarely coetaneous) from a deep globular corm : leaves linear to 

 oblong : petals light rose, usually with deeper-colored veins : few-seeded capsule S-valved- 

 frora top ; the valves chartaceous and more or less conduplicate in age, persistent : race 

 miform inflorescence mainly bractless : flowers (produced in early s))riug) lasting for a 

 few days:. pedicels recurved or drooping in fruit : seeds lenticular, rather narrow-edged, 

 very shining. Species almost confluent in a series. 



C. Virginica, L. A span or two high from a deep and rather large globular compressed 

 corm : leaves linear-lanceolate or linear, 2 to 6 inches long including the gradually tapering 

 base or margined petiole, 1 to 4 lines broad : raceme rather long-peduncled, at length 

 rather many-flowered : petals often half inch long. — Spec. i. 204 ; Lam. 111. t. 144, f. 1 ;

C. Caroliniana, Michx. Lower and fewer-flowered : leaves oblong, oblong-lanceolate, or 

 somewhat spatulate, with blade an inch or two long, abruptly contracted into a margined 

 petiole of same or scarcely half the length : flowers rather smaller. — Fl. i. 160; Ell. Sk. i.

C. lanceolata, Pursh. A span high from a globose corm : leaves oblong or lanceolate, 

 half to inch and a half long; radical (rare) long-petioled ; cauline sessile either by broad or 

 narrowed base : inflorescence few-several-flowered, subsessile between the leaves or short- 

 peduucled : petals emargiuate or almost obcordate. — Fl. i. 175, t. 3 (a large form) ; Plook.

C. umbellata, Watson. An inch or two high from a subglobular or obversely napiform 

 corm : radical leaves unknown ; cauline fleshy, obovate, half inch or more long and con- 

 tracted into a petiole of equal or greater length : inflorescence subsessile and umbelliform, 

 few-several-flowered: petals obovate, entire : seeds comparatively large. — Bot. King Exp.

* * Caudicose; a rosulate cluster of radical leaves surrounding scapiform flowering stems, 

 directly from the very thick crown or perpendicular caudex surmounting the thick and 

 fleshy tap-root : wing-margined petioles of the radical leaves scarious-dilated and mostly 

 as if sheathing at base : no sarmentose shoots or offsets : inflorescence racemiforra or sub- 

 cymose, with or without some small scarious bracts : petals white or pale rose-color, 3 to 5 

 lines long, apparently not ephemeral.
