1. H. lanuginosa Nutt. Pine-sap. Stem fleshy, white or yellowish-red, mi- 

 nutely pubesi'eut. i to 10 inches high; scales and bracts ovate-lanceolate, entire or 

 slightly erose, imbricated below, scattered above; raceme ratlier dense; flowers 

 white; calyx and corolla hairy inside; style densely hairy below the stigma; ovary 

 4 or 5-celled. 



Deep humus of forests, 1000 to 4000 feet : IMendocino Co. to Siskiyou Co. North 

 to Canada, east to New England and Florida. June- Aug. 



Locs. — Mt. Sanhedrin, Hall 9483 ; betw. Acorn and Green Point ranch, Humboldt Co., Jepson

 tropa lanuginosa Michx., Fl. Bor. Am. 1:266 (1803), type from North Carolina. Hypopitys 

 finihriata Jepson, Man. 738 (1925), (f not H. fimbriata 

 Howell). The bracts and sepals are sometimes irregularly or 

 variably a little erose ; but since this character has no con- 

 stancy it seems to be, as to California plants, without signifi- 

 cance in the differentiation of a second species iu our area. m 



19. PTEROSPORA Nutt. 



Reddish-brown saprophytic herb with a single tall 

 stem arising from a thick ball of matted fibrous roots 

 and ending above in a many-flowered raceme. Calyx 

 deeply 5-parted, persistent. Corolla white, globular- 

 urnshaped, with 5 short recurved lobes, withering- 

 persistent. Stamens 10; anthers 2-a\vned on the back 

 near the base, longitudinally dehiscent. Ovary 5- 

 celled; stigma 5-lobed. Capsule depressed-globose, 

 5-lobed. Seeds innumerable, broadly winged from 

 the apex. — Species 1. (Greek jDteron, a wing, and 

 spora, a seed.) 



1. P. andromedea Nutt. PineDrops. (Fig. 314.) 

 Stem stout, fleshy, 1 to 3 (or 4) feet high, glandular- 

 pubescent throughout, bearing numerous lanceolate 

 or linear scales; raceme virgate, den.se at first; pedi- 

 cels slender, spreading, soon recurved ; calyx about % 

 as long as the corolla; corolla white, 2V2 to BY2 lines 

 long. 



Rich humus beneath pines, 4000 to 7500 feet, com- 

 mon : San Jacinto, San Bernardino and San Gabriel 

 mountains; Sierra Nevada from Tulare Co. to Modoc 



Co.; North Coast Ranges from Lake Co. to Siskiyou Co. North to Alaska, east to 

 Pennsylvania and Arizona, south to Mexico. June-July. 



Biol. note. — In such collections as have been made by us in the Sierra Nevada this species 

 appears to be monocarpic, but it is evidently polycarpic in the Rocky Mts., where it was studied 

 by D. T. MacDougal. He states that the short rootstock continues to send up flowering shoots "for 

 two or possibly three seasons" (Ann. Bot. 13:31).
