Plant purplish and glaucous when young. Stem simple, 1-2 feet high, clothed at the base 

 with several oblong imbricated scales. Leaves commonly 2, the petiole of the lowest di- 

 vided nearly to the base ; leaflets 1 -2i inches long and an inch or more wide, often obtusely 

 cunealc at the base, the lateral ones more or less oblique and nearly or quite sessile ; terminal 

 one petiolulate. Panicle small, racemose ; the peduncle arising from the base of the upper 

 leaf. Petals greenish-yellow, about twice the length of the sepals, obovate-lanceolale, ungui- 

 culale, with a reniform viscid scale on the inside at the base. Stamens scarcely one-third the 

 length of the petals ; filaments short and thick ; anthers ovate, opening, as in the greater part 

 of the family, bv two valves, formed by the separation, all around, of the face of each cell ; 

 the valves curving upward, and remaining attached by a small surface. Ovary ovoid, narrowed 

 at the base, obliquely beaked with the short style ; ovules 2, ascending. Pericarp extremely 

 thin, bursting soon after the impregnation by the growth of the young seeds, the vestiges 

 only remaining ; seeds naked, about the size of a large pea (one of them often abortive), glo- 

 bose, deep blue when ripe ; the testa somewhat fleshy, supported on a short thick funiculus : 

 albumen horny, of the form of the seed. 



Fertile rocky woods ; not uncommon. Fl. April - May. Fr. August. The root of this 

 plant is in some repute as a diuretic and bitter, but its powers have probably been overrated. 

 The roasted seeds have much the taste and odor of coffee, but I am not aware of their having 

 been much used as a substitute for that article.
