296 MONOTROPACEAE 



1. Sarcodes sanguinea Torr. Snow Plant. Fig. 3666. 



Sarcodes sanguinea Torr. Smiths. Contr. 6': 18. pi. 10. 1853. 



Stem stout, 2-6 dm. high, often slightly decumbent at base, arising from a thick fleshy mat 

 of roots. Leaves ciliate on the margins, the lower ovate to ovate-lanceolate, 2-3 cm. long, the 

 upper strap-shaped and 5-10 cm. long; bracts conspicuous; sepals broadly lanceolate, 10-15 mm. 

 long; corolla slightly exceeding the calyx, red, glabrous, the lobes rounded, undulate; capsule 

 depressed-globose, 5-lobed, 1-2 cm. broad, subtended by the persistent calyx. 



Coniferous forests. Arid Transition Zone; Cascade Mountains, southern Oregon, south to southern California. 

 Type locality: probably on the Yuba River, California. May-June. 



6. PITYOPUS Small, N. Amer. Fl. 29: 16. 1914. 



Saprophytic herb with white usually glabrous herbage. Stem simple, clothed with 

 crowded or approximate, erect, scale-like leaves, and terminated by a dense bracteate 

 spike or spike-like raceme. Sepals 4 or rarely 5, distinct, persistent. Petals of the same 

 number as sepals, distinct. Stamens twice as many as petals, included ; filaments slender, 

 pubescent ; anthers short, about as broad as long, the sacs opening from the base by longi- 

 tudinal slits. Ovary ovoid, 1-2-celled, with parietal placentae, 4-5-lobed, each lobe with 

 2 ribs ; style cylindric, about as long as the ovary, pubescent ; stigma strongly depressed. 

 Fruit somewhat fleshy, ovoid, 1-celled. [Name Greek, meaning pine and foot in refer- 

 ence to the habitat of these plants.] 



A monotypic genus of the Pacific States. 



1. Pityopus calif ornica (Eastw.) Copel. f. Pityopus. Fig. 3667. 



Monotropa calif ornica Eastw. Bull. Torrey Club 29: 75. 1902. 



Fityopus oregona Small, N. Amer. Fl. 29: 16. 1914. 



Monotropa Hypopitys var. calif ornica Domin, Sitzber. Bohm. Ges. Wiss. Prag. Classe 1915: 24. 1915. 



fityopus californica Copel. f. Madrono 3: 155. 1935. 



Stem rather stout, 10-15 cm. high, glabrous. Leaves deltoid to triangular-lanceolate below, 

 becoming lanceolate on the upper part of the stem, entire or erose ; bracts similar to the upper 

 leaves, shorter than the flowers ; sepals rhombic-oblanceolate to linear, about 12 mm. long ; petals 

 equaling or slightly longer than the sepals, oblong-obovate, pubescent within. 



Deep coniferous woods, Canadian Zone; Cascade Mountains, Oregon, south to Fresno County, California, and 

 in the Coast Ranges from Curry County, Oregon, to Marin County, California. Type locality : dense forest north 

 of Mount Hood, Oregon. June-Aug. 



7. PLEURICOSPORA A. Gray, Proc. Amer. Acad. 7: 369. 1868. 



Saprophytic herb with white or brownish herbage. Stem simple, terminated by a 

 short spike-like raceme. Leaves scale-like, approximate or scattered. Flowers subtended 

 by broad, conspicuous bracts. Sepals 4 or 5, distinct, persistent. Petals as many as sepals, 

 persistent. Stamens 8 or 10, with slender, glabrous filaments; anthers dehiscing by a 

 longitudinal slit. Ovary ovoid, 1-celled, with parietal placentae; style short, stout; stigma 

 depressed-capitate. Fruit a berry, ovoid, 1-celled. not lobed. [Name Greek, meaning at 

 the side and seed, in reference to the parietal placentae.] 



A genus of 1 or possibly 2 species of the Pacific Coast of North America. Type species, Pleuricospora fimbrio- 

 lata A. Gray. 



1. Pleuricospora fimbriolata A. Gray. Pleuricospora or Fringed Pine-sap. 



Fig. 3668. 



Pleuricospora fimbriolata A. Gray, Proc. Amer. Acad. 7: 369. 1868. 



Stem rather stout, 10-25 cm. high, glabrous. Leaves thick, ovate to ovate-lanceolate, the 

 lower entire or erose, the upper fimbriate ; flowers in a rather loosely flowered or dense spike, or 

 narrow raceme; bracts similar to the upper leaves; flowers erect or ascending; sepals ovate- 

 lanceolate to linear-lanceolate, 6-9 mm. long, erose-fimbriate acuminate and involute; petals 

 narrowly elliptic to oblong-lanceolate, about equaling the sepals, entire or sparingly fimbrillate. 



Coniferous forests, Transition and Canadian Zones; British Columbia to Central California. Type locality: 

 Mariposa Grove, California. June-Aug. 



Pleuricospora longipfetala Howell, Fl. N.W. Amer. 429. 1901. This apparently local species may not be 

 distinct from the preceding. It is characterized by the more slender inflorescence, fimbriate lower leaves, and 

 more especially by the spatulate petals which exceed the sepals, and are usually fimbriate at the apex. Known 

 only from collections made near the hot springs, Clackamas County, Oregon. 



8. HEMITOMES A. Gray, Pacif. R. Rep. 6^:80. 1858. 



Fleshy saprophytic herbs, flesh-pink turning brown in age, the stems simple, often 

 mainly subterranean. Leaves scale-like, imbricated, at least below. Flowers in a short 

 dense terminal spike or in a dense corymbiform head, subtended by broad bracts. Sepals 

 2 or 4, narrow. Corolla tubular-campanulate, often slightly constricted at the throat, 

 pubescent within, 4-6-lobed. Stamens 8-10; filaments slender, long-pubescent; anthers 

 oblong, erect on the filaments, dehiscing by a longitudinal slit. Ovary 1-celled, with 4-5 

 two-lobed placentae; style pubescent; stigma depressed-capitate, subtended by a tuft of
