4. CALOCHORTUS, Parsh. Stem branching, from a membranous- 

 coated corm (or this rarely fibrous-coated). Leaves few, linear-lanceolate, 

 the radical 1 or 2 much larger than those of the flexuous stem. Perianth 

 deciduous, of 6 more or less concave segments; the 3 outer small, com- 

 paratively colorless and therefore true sepals. Petals broadly cuneate- 

 obovate, usually with a glandular pit near the base, this apt to be hidden 

 by long hairs. Stamens 6; anthers erect, basifixed. Ovary triquetrous, 

 3-celled; stigmas sessile, recurved. Capsule membranaceous, 3-angled 

 or -winged. Seeds oo , in 2 rows in each cell, flattened; testa thin. 



* Flowers nodding, subglobose with concave petals; capsule broad, 

 obtuse, nodding. 



1. C. albas, Dougl. Glaucous, 1 — 2 ft. high, almost paniculately 

 branching: radical leaves 1 — 2 in. wide: petals pearly-white, with a leaden- 

 lavender tinge outside, round-ovate, 1 — 1J£ in. long, bearded above the 

 gland with long white hairs; gland lunate, shallow with 4 transverse im- 

 bricated scales fringed with short hairs: anthers linear-oblong, obtuse, 

 mucronate: capsule ] — 2 in. long, J£ — 1 in. wide. — Shady banks in the

2. C. pulchellus, Dougl. Half as tall as the last, more branching 

 and floriferous: radical leaf equalling or exceeding the stem: sepals 

 greenish-yellow, 8 — 12 lines long, nearly equalling deep yellow oblong- 

 ovate aculish petals, these glandular-ciliate, and with scattered short 

 erect yellow hairs ; gland a deep pit, produced upward and covered by 

 stiff appressed yellow hairs: anthers broad, obtuse or acutish: capsule 

 elliptical. — Cool summits of the more elevated Coast Range hills and 

 mountains, in shade of thickets.

3. C. Maweanus, Leichtl. Stem low (3— 10 in. high), 3 — 6-flowered: 

 glaucous leaves surpassing the stem: petals white to purplish-blue, 

 exceeding the purplish sepals, broadly obovate, acute, somewhat arched 

 and pitted, the broad naked claw with a transverse semicircular scale, the

4. C. lilacinns, Kell. Stem 4— 8 in. high: leaves long and broad :Jt.
