cent calyx and stamens, at length bursting irregularly, or longi-

 ing, 6-12 inches long: leaves rounded-cordate with large rounded auricles, 

 dark green, not marked with white, 2-4 inches broad, rather sparsely pu- 

 bescent with short stiff hairs, obscurely crenulate and finely ciliate, on 

 sparsely hairy petioles 3-10 inches long, rema'ning green until the next 

 pair are mature; flowers solitary in the axils of the leaves and thus becom- 

 ing terminal, on slender peduncles 1-2 inches loner, dark brown, the ovate 

 lobes attenuate into slender appendages 1-3 inches long, more or less pu- 

 bescent : filaments stout, the free apex of the ronnective much shorter than 

 the anthers: styles united, equalling the stamens: seeds ovate, \% lines 

 long. In forests, Brit. Columbia to California. 



A. Hartwegl Watson Proc. Am. Acad x, 346. ? Rather stout, tufted, 

 more or less floccose-pubescent : leaves usually large, 2-6 inches long, 

 rather thick and marked with white above, nearly smooth, deeply cordate 

 with large rounded auricles, somewhat acuminate, finely ciliate, on woolly 

 petioles 4-8 inches long: peduncles 6-18 lines long : ovary about r> lines 

 broad, white w r oolly : lobes of the calyx ovate, narrowed to linear append- 

 ages 1-2 inches long: filaments rather stout, nearly free from the styles: 

 anthers about a line long, the produced connective setose, about a line long : 

 styles short, nearly distinct, scarcely equalling the anthers: seeds ovate,

PL Nov. Hoi. i, 350. (1810) 



Herbs shrubs or trees with alternate or opposite leaves with-

 terminal flowers. Calyx adnate to the base of the ovary or to 

 the disk, 3-5-lobed, the lobes valvate. Stamens as many as 

 lobes of the calyx and inserted near their bases, or opposite 

 them upon the lobes of an annular disk. Ovary 1-celled: 

 ovules 2-4:, pendulous from the summit of the central placenta. 

 Style cylindric or conic, sometimes wanting: stigma capitate. 

 Fruit a drupe or nut. Seed solitary, ovoid or globose, without

Glabrous perennial herbs, mostly parasitic on the roots of other 

 plants with alternate leaves and small perfect flowers in terminal 

 and axillary bractless cymes. Calyx campanulate, the base of 

 its tube adnate to the ovary, its limb 5-lobed, Stamens inserted 

 at the base of the calvx-lobes and between the lobes of the disk, 

 attached to the middle of the lobes by tufts of hairs. Anthers 

 ovate, 2-celled. Fruit drupaceous, crowned by the persistent calyx. 



C. umbellata Nutt. 1. c. Stems slender, very leafy, branched, 6-18 

 inches high : leaves oblong or oblong-lanceolate, pale green, acute or acut- 

 ish at both ends, sessile, ascending, 6-15 lines long, the lower smaller: 

 cymes several-flowered corymbose at the summit of the stems and often 

 axillary also: peduncles slender, 3-12 lines long: pedicels very short: calyx 

 greenish-white or purplish, about 2 lines high: style slender : drupe globose, 

 about 3 lines in diameter, crowned with the upper part of the calyx-tube
