13. ODONTOSTOMUM Torr. Pacif. R. Rep. 4: 150. pi 24. 1857. 



Erect, glabrous herb with fibrous-coated corm, narrow mainly basal leaves and paniculate 

 flowers subtended by scarious bracts. Perianth tubular with a spreading or reflexed 6-parted 

 limb, white or yellowish, tardily deciduous, the segments oblong, about equalling the tube, the 

 outer 5-7-nerved, the inner 3-5-nerved. Stamens 6, inserted on the throat, alternating with 

 as many very short linear staminodia ; filaments very short, narrowly subulate ; anthers basi- 

 fixed, dehiscent at the summit. Ovary globose, sessile ; ovules 2 in each cavity, ascending ; 

 style filiform, slightly 3-cleft. deciduous. Capsule triangular-obovate, 3-lobed, loculicidally 

 dehiscent. Seeds solitary, obovate, with a close thin dark brown slightly rugose testa. [Greek 

 odous, tooth, and stoma, mouth, referring to the staminodia on the throat.] 



A monotypic genus peculiar to California.

Odontostomtim liartzvegi Torr. Pacif. R. Rep. 4: 150. 1857. 



Corm deep-seated, subglobose, about 25 mm. in 

 diameter. Stem 20-45 cm. high, simple below or usu- 

 ally paniculate from near the base ; leaves basal or 

 near the base, linear-lanceolate, 8-12 cm. long, 5-7 mm. 

 wide, the lower stem leaves similar, the upper be- 

 coming reduced to bracts subtending the panicle 

 branches ; bracts subulate about equalling the pedi- 

 cels ; pedicels slender, 3-5 mm. long, with a small 

 bractlet near the middle ; flowers rather numerous, 

 the tube cylindric, 5-6 mm. long, 12-nerved, the seg- 

 ments about equalling the tube, at length reflexed; 

 capsule about 4 mm. in diameter. 



Dry usually adobe hillsides, Upper Sonoran Zone: vicinity 

 of Redding south to Mariposa County in the Sierra foothills 

 and to Napa Valley in the Coast Range. A rather rare 

 plant, but sometimes locally abundant. Type locality: Sacra- 

 mento Valley, probably in Butte County. 



14. SCHOENOLIRION Durand, Joiirn. Acad. Philad. II. 3: 103. 1855. 



Stem naked or sparingly leafy, from a coated bulb. Leaves linear, flat. Inflorescence a 

 densely many-flowered sparingly panicled raceme, with small scarious bracts. Perianth white 

 or greenish, lax and becoming scarious, persistent, divided to the base into 6 distinct, oblong, 

 closely 3-nerved segments. Stamens 6, adnate to the base of the segments ; anthers versatile, 

 linear-oblong. Ovary ovate, very shortly stipitate ; style short, persistent ; ovules 2 in each 

 cavity. Capsule ovoid, broken by the slender persistent style, loculicidally dehiscent. Seeds 2 

 in each cavity, oblong, black. [Greek, meaning rush and lily.]

 inently 3-nerved ; stamens about equalling the seg- 

 ments ; anthers about 1 mm. long; capsule broadly
