LILIACE.E. 319 



1. C. ixioides (Ait. f.). Scape a foot high: leaves 2: filaments alter- 

 nately long and short, all bifurcate at the winged summit, the oblong 

 anther on a cusp in the middle between the forks. From below San 

 Francisco northward, in the Coast Range. May. 



2. C. lugens (Greene). Like the preceding in size and general 

 appearance, but the broad appendages of the filaments rounded, not forked, 

 at summit: perianth deep saffron-color within; exteriorly the entire tube, 

 'and midvein of the, segments, dark brown approaching black. Yaca 

 Mountains; collected only by the author. May. 



18. TRITELEIA, Douglas. Vegetative organs as in Calliprora. 

 Flowers blue, or bluish. Perianth-tube funnelform or turbinate, not 

 inflated or angular or saccate though thin. Stamens 8, all antherif erous ; 

 filaments coalescent with the upper portion of the perianth-tube, reap- 

 pearing near the base in the form of thin but prominent crests; anthers 

 small, versatile. Ovary on a slender stipe. 



1. T. laxa, Benth. Scape 12 ft. high: umbel 10 30- flowered: 

 perianth \% in. long, funnelform, pale to deep violet, cleft nearly to the 

 middle: filaments free for a line's length above the insertion; anthers 

 ovate-lanceolate, 2-lobed at base, erect, though fixed near the middle: 

 stipe of ovary ^ in. long. Very common in fields and on open hillsides. 

 May, June. 



2. T. peduncular is, Lindl. Scape 13 ft. high: umbel 15 30-flow- 

 ered; pedicels very long, often 610 in.: perianth broad-funnelform, pale 

 rose-purple to nearly white, 1 in. long, cleft below the middle; segments 

 widely spreading; anthers oblong-linear, retuse at summit. Wet banks 

 of streams and in springy places. June, July. 



19. HESPEROSCORDUM, Lindl. Sufficiently differentiated, as a 

 genus, from the preceding, by its rotate-campanulate perianth cleft to 

 the middle, the segments taking no angle of divergence of their own (not 

 spreading), and filaments deltoid-dilated and monadelphous below; the 

 anthers basifixed and erect. 



1. H. lactenm, Lindl. Scape slender, 12 ft. high; perianth 5 8 

 lines long and as broad, white, with green veins, or sometimes with a 

 tinge of lilac: stamens all alike: capsule short-stipitate. Plentiful in 

 rather low rich soils. May, June. 



20. MUILLA, S. Wats. Somewhat succulent scape and semiterete 

 leaves from a coated corm. Umbel with several narrow scarious bracts. 

 Perianth-segments and stamens 6 each and distinct or nearly so, white 

 or greenish. Genus differing from all the foregoing umbellate-flowered 

 genera in that the pedicels are not jointed under the perianth, and from 

 Alliurn in that the plants are destitute of alliaceous properties.
