318 LILIACE3). 



unequal: perianth-tube fuunelform, not constricted, shorter than the 

 segments: stamens all antheriferous, their appendages forming a corona 

 that is connivent. Rocky hills, in the open country. March, April. 



* * Flowers rose-purple or pinkish. 



3. D. Californicum (Torr.), Wood. Scape 410 ft. high, in smaller 

 plants tortuous, in taller firmly twining by several abrupt turns, perianth 

 pink to rose-red, 68 lines long; lube 34 lines long and broad, hexag- 

 onal, the angles somewhat saccalely produced above the middle; segments 

 rotate, the very tips recurved: fertile stamens 3; anthers linear-sagittate; 

 appendages of these and the staminodia emarginate and ciliolate- 

 scabrous. Foothills of the coast ranges. May, June. 



* * * Flowers scarlet, but green-tipped. 



4. D. Ida-Maia (Wood). Scape not twining, but distinctly tortuous; 

 perianth-tube 1 in. long, scarlet, broadly tubular, somewhat 6-saccate at 

 the truncate base; segments short, spreading, chrome-green: fertile 

 stamens 3; staminodia and appendages of perfect stamens yellow. 

 Coast Range woods from Marin Co. northward. May, June. 



16. HOOKERA, Salisb. Scapes straight, firmly erect. Umbel few- 

 flowered, the pedicels firm and perianth erect. Perianth-tube thick, 

 opaque, turbinate; segments equalling the tube, spreading, or recurved 

 at tip. Filaments 6, stout, angular, inserted at the throat but prominent 

 down to the base of the tube; 3 antheriferous, the alternate 3 bearing 

 white-petaloid lamellae. Anthers basifixed. 



1. H. coronaria, Salisb. Scape stout, 1 ft. high: pedicels 3 10, 

 13 in. long: perianth 1 in. long or more, purple: anthers 45 lines 

 long, exceeding the oblong-lanceolate staminodia. Very common and gen- 

 erally distributed. May, June. 



2. H. minor (Wats.), Britten. Scape slender, 36 in. high: pedicels 

 26, mostly 1 3 in. long: perianth usually less than 1 in. long; limb 

 rotate: anthers 2 lines long, shorter than the retuse or emarginate stamin- 

 odia. Plains of the interior, if at all within our limits. 



3. H. terrestris (Kell.), Britten. Scape usually altogether subter- 

 ranean, only the umbel above ground: pedicels 2 30, slender, 34 in. 

 long: perianth less than 1 in.; limb rotate: anthers \%. lines long, 

 shorter than the yellowish emarginate staminodia, the margins of which 

 are revolute. Near the coast from San Francisco northward. June. 



17. CALLIPRORA, Lindl Slender scape and few broad-linear thin- 

 nish leaves from a depressed fibrous-coated corm. Flowers yellow, with 

 dark brown lines. Perianth-tube short; segments rotate-spreading. 

 Filaments, below their insertion (at throat of perianth) coalescent with 

 the tube and not obvious, free and broadly appendaged above it, all (6) 

 antheriferous; anthers versatile.
