104 LIL1ACEAE. 



Mt. Bamilton (R. L. Pendleton); Mt. Diablo; Pope Valley. 



5. A. lacunosum Wats. Scape 3 to 6 in. high; bulb-coats light colored, 

 thick and distinctly pitted by the quadrate or transversely oblong reticulation, 

 the outline of the cells very minutely sinuous; umbels 10 to 20-flowered, the 

 pedicels 3 to 5 linos long; bracts broadly ovate, tipped with a slender-subulate 

 point; flowers small (3 lines long); perianth-segments oblong-lanceolate, or 

 oblong, acute, a little exceeding the stamens; filaments narrowly deltoid below; 

 ovary-cells with an obtuse thickened ridge toward the summit on each side. 



Mariposa Peak, Santa Clara Co., Brewer; Mt. Hamilton, R. L. Pendleton. 



6. A. serratum Wats. Bulb-coats with a distinct close horizontally serrate 

 reticulation; bracts narrowly acuminate; perianth-segments pink, broadly ovate- 

 Lanceolate, 4 to lines long, acute or somewhat acuminate, nearly straight 

 and rather rigid, the inner narrower, somewhat shorter and rarely serrulate; 

 filaments all with a narrowly deltoid base; crests very narrow, central. 



Low hills. 



7. A. attenuifolium Kell. Bulb-coats commonly reddish, with a delicate trans- 

 versely sinuate or serrate reticulation, the vertical lines especially also minutely 

 sinuous; scape slender, 6 to 13 in. high; leaves narrow and becoming convolute- 

 filiform above the sheathing base; bracts 2, short, abruptly acute; umbel erect, 

 usually dense; pedicels 25 to 35, 3 to 8 lines long; flowers white or nearly so, 

 the oblanceolate acuminate segments 3 or 4 lines long, more or less exceeding

North Coast Ranges and Sierra Nevada. Var. monospermum Jepson. 

 Scapes in clusters of 2 to 4; bracts 3; capsule by abortion 1-celled and 1 -seeded.

10. CAMASSIA Lindl. 



Acaulescent plants with linear leaves, slender scapes from a tunicated bulb, 

 and dark blue or nearly white flowers in a simple raceme. Bracts scarious. 

 Pedicels jointed at the summit. Perianth-segments 6, distinct, oblanceolate, 

 somewhat spreading. Stamens 6, on the base of the perianth, shorter than the 

 Begments; anthers versatile. Style filiform, slightly 3-cleft at apex, the lower 

 part persistent. Capsule 3-lobed, loculicidally 3-valved. Seeds several in each 

 cell. (Quamash or camass, the name of the northwest Indians.) 



1. C. esculenta Lindl. Camass. Scape stoutish, 1 to 2% ft. high; flowers 

 blue; perianth-segments unequal, spreading irregularly in 2 sets of 3 each, 

 nearly 1 in. long, not twisted over the obtusely angled capsule. 



Wet meadows, Santa Rosa and Napa valleys and northward to Washington. 



('. i.kk iiti.ixii Wats. Flowers dark blue to white; perianth-segments spread- 

 ing regularly in a perfect star, withering over the capsule like a bon-bon. 

 at length deciduous as a whole; capsule oblong-obovate, slightly notched at 

 apex.— Bed Mt. near Ukiah, Purely, and northward to Washington. 



11. CHLOROGALUM Kunth. 

 St. in from a tunicated bulb, tall, almost leafless, branching above into a 

 spreading panicle, the branches racemose and sparingly branched or simple. 



Leaves of the radical tut't long-linear, those of the stems very much reduced. 

 Bracts small and scarious. Pedicels jointed at the summit. Perianth white 



or pinkish, persist mt ami at length twisted o\ er the ovary; segments 6, distinct, 



spreading, ribbon-like, with :\ distinct but closely approximate nerves down the 

 middle. Stamens ti, rather shorter than the segments and inserted on their
