Blood-root. 



Calyx of 2 ovate sepals, slightly imbricated in aestivation, 

 caducous. Petals 8 to 12, obovate-oblong or spatulate, im- 

 bricated in two or three series, hypogynous, spreading, the 

 innermost often narrower, early deciduous. Stamens about 

 24, hypogynous, much shorter than the petals : filaments 

 filiform, short : anthers oblong-linear, innate, the cells 

 opening longitudinally by a marginal and obscurely extrorse 

 line. Ovary oblong, one-celled, with two parietal placentas : 

 style short, columnar : stigma broad, sulcate - two-lobed, the 

 lobes alternate with the placentae. Ovules very numerous, 

 horizontal in several rows on the two placentae, anatropous. 



Capsule oblong, somewhat compressed, herbaceo-coria- 

 ceous, many-seeded, pointed by the short persistent style, 

 two-valved ; the valves separating from the replum formed 

 of the two intervalvular filiform placentas. Seeds horizon- 

 tal, obovoid, with a smooth crustaceous testa, the raphe 

 strongly crested. Embryo minute at the base of the fleshy 

 albumen, cordate. 



Herb with a large branching tuberous rhizoma, surcharg- 

 ed with orange-red juice, sending up in earliest spring, from
