1. ZYGADENUS Michx. Zygadene. 



Stems simple, scale-like, from a tunicated bulb, gla- 

 brous and somewhat glaucous, with linear mostly basal 

 leaves and greenish-w^hite flowers, in a raceme or panicle. 

 Perianth nearly rotate, segments ovate to oblong-lanceo- 

 late, with a green glandular spot at the narrowed base. 

 Stamens free from the segments and about equaling 

 them; filaments subulate. Styles distinct, persistent. 

 Capsule deeply 3-lobed. Seeds brownish, angled. 



1. Z. fremontii Torr. Bulb oblong, 2-5 cm. long, with dark 

 coats; stems 4-8 dm. high; basal leaves 2-4 dm. long, 1.5-2.5 cm. 

 broad at the base, somewhat falcate-curving; stem leaves few, 

 shorter, sheathing at the base; flowers few to many in a raceme or 

 panicle; lower pedicels 2.5-4 cm. long; segments 8-14 mm. long, 

 the outer not clawed, the inner with a broad claw; gland greenish 

 yellow, toothed on its upper margin; stamens about as long as the 

 segments; capsule oblong, about 2 cm. long. 



Occasional on the northern slope of the Santa Monica Mountains 

 and Verdugo Hills. April. 



2. CHLOROGALUM Kunth. Soap-plant. 



Stems from a fibrous-coated bulb, tall, almost leafless, 

 paniculately branched above, the branches loosely race- 

 mose. Basal leaves tufted, long-linear, the stem leaves 

 much reduced. Bracts small and scarious. Pedicels 

 jointed at the summit. Perianth white or purplish, per- 

 sistent and at length twisted over the ovary, its segments 

 distinct, ligulate, spreading, with 3 closely approximate 

 nerves down the middle. Stamens 6, inserted on the 

 base of the segment; anthers versatile. Style long-fili- 

 form, slightly 3-cleft. Capsule broadly turbinate, 3- 

 valved, loculicidal. Seeds 1 or 2 in each cell, obovate, 

 somewhat rugose. 



1. C. pomeridianum (Ker.) Kunth. Bulbs large, about 1 dm. 

 long, densely and coarsely fibrous-coated; stem and spreading 

 panicle 6-15 dm. high; leaves 2-5 dm. long, 12-30 mm. broad, 

 carinate and undulate; pedicels slender, about 6 mm, long; perianth
