96 LILIACEAE. 



flowers many, pink, on pedicels 2-3 cm. long; perianth segments ovate, acum- 

 inate, 10-12 mm. long; ovary only obscurely crested. 



In stony open places, British Columbia to California and Utah. 



109. CALOCHORTUS. Mariposa Lily. 



Branched or simple herbs with coated corms; leaves narrowly 

 linear; flowers large, showy, peduncled; perianth-segments sepa- 

 rate, spreading, whitish, purplish or variegated, the three outer 

 sepal-like, narrow, the three inner petal-like, gland-bearing, and 

 bearded or spotted within; stamens 6, hypogynous; ovary 3- 

 celled; ovules numerous. 



Sepals each with a conspicuous pit at base; anthers apiculate. 



Pit round; anthers as long as the filaments. C. subalpinus. 



Pit linear; anthers shorter than the filaments. C. lobbii. 

 Sepals without a pit at base; anthers acute. 



Gland of each petal covered by a scale. C. purdyi. 



Gland of each petal naked. C. tolmiei. 



Calochortus subalpinus Piper. Stems flexuous, 15-20 cm. high ; leaf 3-8 mm. 

 wide; sepals lance-ovate with a conspicuous round purple pit at base; petals 

 cream-colored, sparsely bearded, except near the tip, the gland bordered above 

 by a narrow entire scale; anthers long-apiculate, equalling or longer than the 

 filaments. 



In subalpine meadows, Mount Adams and southward. 



Calochortus lobbii (Baker) Purdy. Very similar to C. subalpinus; pit 

 at base of each sepal linear; petals bearded to the tip; anthers apiculate, shorter 

 than the filaments. 



Cascade Mountains of Oregon; perhaps not distinct from C. subalpinus. 



Calochortus purdyi Eastwood. Stems 20-40 cm. tall, usually branched; 

 leaves linear-lanceolate, flat, 10-12 mm. broad; sepals narrowly ovate, acumin- 

 ate; petals broadly obovate, dirty- white or purple-tinged, bearded on the 

 inner surface, the shallow honey-pit covered by a densely hairy narrow scale. 



In grassy meadows, rare. Seattle, Piper, and in the Willamette Valley, 

 Oregon. 



Calochortus tolmiei Hook. & Arn. Stems about 30 cm. high, simple or 

 branched; leaves 10-12 mm. broad; sepals oblong-lanceolate, acuminate; 

 petals yellowish, tinged with purple, bearded, the deep gland near the base 

 without a scale, but bordered above by a fringe of reflexed hairs; anthers acute. 



Willamette Valley, Oregon. It is not clear that C. tolmiei and C. purdyi 

 are really distinct. 



110. LILIUM. 



Perennial herbs with scaly bulbs and simple stems with numer- 

 ous alternate or whorled narrow sessile leaves; flowers one to 

 several, large, showy, erect or nodding; perianth funnelform or 

 bell-shaped, the 6 segments spreading or recurved; anthers 

 linear, versatile; style elongated; stigma 3-lobed; capsule sub- 

 cylindric; seeds numerous, in 2 rows in each cell. 



Flowers orange with purplish dots. L. columbianum . 



Flowers white, becoming purplish. L. washingtonianum.
