HYDROPHYLLACE/K. 



L. acicularis Greene. But 1 to 4 in. high, very slender, some- 

 what rigid, less pubescent than L. parvitiorus; leaf-segments linear- 

 acerose; corolla golden-yellow throughout, its tube slenderly filiform, 

 about 6 lines long, the obovate lobes not exceeding 1 line. 



Not common: Oakland Hills; Marin Co.; Napa Valley; Hoopa 

 Valley. Apr. -May. 



10. L. bicolor (Nutt.) Greene. Very near L. parviflorus but 

 dwarf, 1 to 3 in. high; leaves and bracts hispidulous-ciliate; limb 

 of corolla very short (1 to 1£ lines long) in proportion to the tube 

 which is 6 to 9 lines long, dull purple or pink with yellow throat. — 

 (Gilia tenella Benth.) 



Rarely collected, but doubtless overlooked for L. parviflorus: Hoopa 

 Valley; near Suisun; Marin Co.; Mt. Diablo Range; Loma Prieta 

 and southward to Southern California. 



11. L. ciliatus (Benth.) Greene. Rigid, 4 or 5 in. (rarely 1 ft.) 

 high; stems finely tomentose, the internodes long; leaves scabrous 

 and hirsute: flowers comparatively few; corolla G to 9 lines long, not 

 exceeding or often much exceeding the conspicuously hirsute-ciliate 

 bracts, deep rose-red, often fading white, the lobes 1 line long, seldom 

 more; calyx-lobes acerose.— (Gilia ciliata Benth.) 



Hills and mountain slopes, among Oaks and other trees: Coast 

 Ranges (Napa Co.. Mt. Diablo); Sierra Nevada; Southern California. 



91. HYDROPHYLLACE/E. Phacelia Family. 



Herbs or shrubs with opposite or alternate leaves. Flowers reg- 

 ular, 5-merous (except the superior ovary which is 1 or 2-celled), in 

 racemes or spikes (often scorpioid), or capitate, or solitary. Stamens 

 near the base of the corolla, alternate with its lobes. Styles 2, dis- 

 tinct, or more or less completely united even to the stigmas. Fruit a 

 1-celled capsule or partly or quite 2-celled by the intrusion of the 

 placenta? or their union in the axis; valves 2, rarely 4. Seed-coat 

 pitted, the cavities regular and honeycomb-like. 



Leaves (at least the lower) opposite, or alternate or radical in no. 1; ovary 

 and capsule 1-celled ; placentae expanded and forming a sac-like lin- 

 ing to the pericarp; style 2-cleft; ovary more or less hispid. 

 Stamens longer than corolla; flowers in head-like clusters; perennials. . . 



1. Hydrophyi.i.vm 



stamens shorter than corolla; flowers solitary or in racemes; annuals. 

 Calyx with a reflexed appendage at each sinus; seeds carunculate . . . . 



2. Nemophila. 



Calyx naked at the sinuses; seeds not carunculate . . 3. Ellisia. 

 Leaves alternate or mainly radical in no. 6; calyx appendages none. 

 Ovary and capsule 1-celled, or incompletely or completely 2-celled hy the 

 approximation or union of the linear or lanceolate placenta? (borne on 

 semisepta) in the axis; annual or perennial herbs. 

 Style 2-cleft, at least at apex; ovary more or less pubescent; flowers in 

 scorpioid racemes or spikes. 



Corolla blue, purple, or white, deciduous 4. Phacelia. 



Corolla yellow or cream-color, persistent 5. Emmenanthe. 



Style and stigma entire; ovary glabrous; corolla white; flowers; 



racemose 6. Romanzoffia. 



Capsule almost 2-celled, 4-valved, the valves bearing the dissepiments or 

 half-partitions on their middle; styles 2, distinct; shrubs with thick 

 leaves 7. Eriodictyon.
