PLEUROCOSPORA 



5 HYPOPITYS Adans. Fam. PI. ii, 443. 



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- 

 subulate ; anthers reniform, the cells completely confluent into 

 one, which opens by very unequal valves, the larger broad and 

 spreading, the other remaining erect and contracted. Style col- 

 umnar : stigma funnelform, glandular or hairy on the margin. 

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

 erous, small, scobiform ; the nucleus minute in the loose-cellular 

 coat. Only the following species known. 



H. lutea Dill. Monotropa Hypopitys L. Red yellowish or white 

 stems 6-12 inches high : bracts ovate-lanceolate, entire or slightly erose, 

 densely imbricated at the base, scattered above : flowers 3-20, in a loose 

 drooping at length erect raceme, 5-7 lines long, the terminal one 5-merous, 

 the others usually 3-4-merous. In forests, Brit. Columbia to California 

 and the eastern States. Europe and Asia. 



H. ftmbriata. Monotropa fimbriata Gray. Stems 6-12 inches high, 

 red or yellowish, somewhat hairy: upper scales and bracts obovate to cu- 

 neate, erosely or laciniately fimbriate: lateral flowers often 3-petalous and 

 6-androus : sepals spatulate, laciniate. In forests of the Cascade and Coast

Tribe 2 Pleuricosporese Gray Syn. Fl. ii, 18. Ovary ^-celled 

 or spuriously 4-5-celled: the 4 or 5 placentas parietal and 2-lamellate.

Low fleshy white or yellowish herbs with fimbriate scales arid 

 petals, and white flowers in a short terminal raceme. Calyx 

 complete, of 4 or 5 scale-like sepals. Corolla of 4 or 5 plain pet- 

 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. flmbriolata Gray 1. c. Stout and 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 petal? 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
