 Leaves (or some of them) pinnately parted with the divisions incised or 

 parted. 

 Stamens exserted; capsule 1-celled. 

 Leaves with innocuous teeth; flowers creamy white, 4-merous . . 



12. a. cotulxfolia. 

 Leaves with pungent teeth, the terminal leaflet spatulate-dilated; 

 capsule J-seeded . . .13, O. pubeacens. 



Stamens not exserted. 

 Seeds 8 to 12 in each cell ; herbage strongly mephitic-scented . . 



11. <-'. squarroxa. 

 Seeds 4 in each cell; herbage honey-scented . . .15. a. mtllita. 



Leaves merely pinnatifld or incised or many of them entire. 

 Capsule several-seeded. 

 Erect slender plants; bractlets laciniately cleft, especially toward 



the base 16. G. heterodoxa. 



Low verjf rigid and spiny plants ; bractlets dilated and with strong 



marginal spines 17. G. atractyloides. 



Cells of capsule 1-seeded ; corolla 6 or 7 lines long; bractlets, especially 

 the inner ones, lanceolate-cleft at apex ... 18. (;. viscidula. 



1. G. gracilis Hook. Three to 8 in. high, either simple or 

 "branched above; herbage pilose-puhescent, the hairs often gland- 

 tipped; leaves opposite, oblong to lanceolate, entire; inflorescence 

 cymose and terminal; calyx cylindrical, 3 or 4 lines long, much dis- 

 tended in fruit by the globose capsule, the short teeth accrescent; 

 tube of corolla yellow, surpassing the calyx, the limb 1 to IJ lines 

 broad, its lobes i-oundish, emarginate; stamens unequally inserted; 

 seeds 1 in each cell, with a rather broad thin margin. — (CuUomia 

 gracilis Dougl. Microsteris Californica Greene.) 



Inconspicuous but rather common on low hills of the Coast Ranges 

 and in the Sierra Foothills. Mar.-Apr. 



2. G. gilioides (Benth.) Greene. Loosely branching, erect or 

 diflfuse, 8 to 20 in. high; radical and lower leaves pinnately parted 

 into narrowly oblong or lanceolate divisions, or all so divided, or the 

 upper palmately divided into 3 to 5 obovate or lanceolate divisions; 

 corolla 4 to 6 lines long, salverform, blue-purple; stamens unequally 

 inserted; capsule globose; seeds 1 or 2 in each cell. — (Collomia 

 gilioides Benth.) 



Mostly at higher altitudes in the mountains: Coast Kanges; Sierra 

 Nevada; Southern California. June. Leaves exceedingly variable. 



3. G. multicaulis Benth. Branching from the base, 9 to 14 in. 

 high, glabrous; leaves pinnately parted into 5 to 9 linear and entire 

 or toothed lobes; flowers subsessile or the clusters loose, in either case 

 few-flowered, the pedicels 1 to 4 lines (rarely 1 in.) long; calyx-teeth 

 erect or recurved in fruit; corolla deep or pale blue, its proper tube 

 shorter than the calyx, the funnelform throat longer than the obovate 

 lobes; stamens unequally inserted; capsule ovoid.
