tions with the central axis, from which the placentae are pendulous. Seeds verj^ 

 numerous, ovoid, with a thin nearly close coat, apiculate at base, and at apex bear- 

 ing a broad hyaline and reticulated wing-like appendage, many times larger than 

 the seed itself. — Nutt. Gen. i. 386 ; Lindl. Collect, t. 5. — Single species. 



1. P. andromedea, Nutt. A stout, purplish-brown or chestnut-colored and 

 clammy-pubescent herb, 1 to 3 feet high : the lanceolate scales or bracts small, 

 crowded at the base, scattered above : raceme long, virgate, many-flowered ; the 

 spreading and recurved pedicels slender, as long as the linear scarious bracts : 

 corolla white, a quarter of an inch long, somewhat viscid : capsule a third of an inch 

 in diameter. 



In dry soil, under pines or other coniferous trees and oaks, from Monterey northward, extend- 

 ing to British Columbia and through the Northern Atlantic States. 



17. SARCODES, Ton-. Snow-Plant. 



Calyx of 5 oblong erect sepals, shorter than the corolla, persistent. Corolla 

 cylindraceous-campanulate, moderately 5-lobed, the lobes little spreading, persistent. 

 Stamens 10, included, glabrous : filaments slender : anthers linear-oblong, attached 

 l)y the outside a little above the base, not appendaged, the 2 cells united through- 

 out and with a very narrow connective, opening by the whole obliquely truncate 

 apex. Ovary 5-lobed, 5 -celled : style columnar : stigma capitate, slightly 5-lobed. 

 Capsule fleshy ; the thick placentae adnate to the axis for their whole length. Seeds 

 very numerous, oval ; the coat cellular-reticulated, but closely fitted to the nucleus, 

 except a conical protuberance at the apex. — Torr. PL Fremont, in Smithsonian 

 Contrib. 17, t. 10. 



1. S. sanguinea, Torr. 1. c. A stout fleshy herb, a span or two in height, of a 

 bright red color, more or less glandular-pubescent, thickly clothed, at least up to the 

 raceme, with firm fleshy scales ; the lower ones ovate and closely imbricated, the 

 upper gradually more scattered, narrower, and passing into the linear bracts, which 

 mostly exceed the flowers, their margins glandular-cihate : pedicels erect, at least 

 the upper ones short : corolla half an inch long, rather fleshy, glabrous. 



In coniferous forests, especially those of Sequoia and Abies, through the Sierra Nevada from 

 4,000 to 9,000 feet, shooting fortli and flowering as soon as the snow melts away. 



18. MONOTROPA, Linn. Indian Pipe. Pine-Sap. 

 Calyx of 2 to 5 lanceolate often loose and dissimilar bract-like scales, deciduous. 

 Corolla of 4 or 5 erect spatulate or oblong scale-like petals, wliich are gibbous or 

 saccate at base, tardily deciduous. Stamens twice as many as the petals : filaments 

 filiform-subulate : anthers more or less reniform, transverse upon the apex of the 

 filament ; the cells more or less confluent into one, opening across the top. Style 

 columnar, tubular, more or less dilated at the apex into the disk-like or somewhat 

 funnelform obscurely 4-5-crenate stigma. Disk confluent with the. base of the 

 ovary, bearing 8 or 10 deflexed teeth. Capsule ovoid, 4-5-celled: the thick pla- 

 centaj covered with innumerable minute loose-coated seeds. — Low fleshy-scaly herbs, 

 white or reddish, turning brownish ; the clustered and loosely scaly stems rising 

 from a ball of matted fibrous roots ; the flowering summit at first nodding, becom- 

 ing erect in age. — Two or three species, of two well-marked subgenera, by many 

 received as genera ; but the difl'erences are rather unimportant.
