Low fleshy scaly-bracted plants with red or yellow flowers in 
a_loose terminal raceme. Sepals 3-5, nearly equal, erect, decidu- 
ous. Petals 4-5, longer than the sepals, saccate at base. erect 
with spreading tips, deciduous. Stamens 6-10; filaments filiform-

Capsule ovoid, the columella thick and fleshy. Seeds very num-

the others usually 3-4-merous. In forests, Brit. Columbia to California 
and the eastern States. Europe and Asia. 
H. fimbriata. Monotropa fimbriata Gray. Stems 6-12 inches high, 
red or yellowish, somewhat hairy: upper scales and bracts obovate to cu-

Low fleshy white or yellowish herbs with fimbriate scales and 
petals, and white flowers in a short terminal raceme. Calyx

als resembling the sepals. Stamens twice as many as petals: 
filaments ligulate-filiform: anthers linear, apiculate, the cells 
opening from base to apex into two equal valves. Ovary strictly 
one-celled. Style columnar: stigma depressed-capitate, or some- 
what funnelform. Seeds ovate, with a smooth or polished coat. 
P. fimbriolata Gray 1. c. Stoutand erect, 3-10 inches high, glabrous 
or nearly so, clothed with imbricated scales; lowest scales ovate, firm, 
entire; upper passing into the narrower and lanceolate scarious margined 
and lacerate fringed bracts of the dense and erect cylindraceous raceme: 
sepals and petals white, oblong or oblong-lanceolate fimbriate-lacerate, 
not exceeding the bracts. In the Cascade and Coast Mountains of Oregon 
and the Sierra Nevadas of California 
P. longipetala. Stem rather slender, 4-6 inches high: scales well 
imbricated, lanceolate, more or less acuminate, laciniately toothed: flowers
