456 POLEMONIACEAE 



filaments subequaling anthers ; pistil of 4 carpels, stigma 4-lobed, included ; capsule 4-valved, 

 campanulately spreading on dehiscence. A remarkable species closely related to Leptodactylon 

 Watsonii A. Gray of the Rocky Mountains region. 



Dry rocky places, Canadian Zone; known only from a few localities in the San Jacinto Mountains, California. 

 Type locality: Tahquitz Peak, San Jacinto Mountains. May-July. 



11. GILIA Ruiz & Pav. Fl. Peruv. Prod. 25. 1794.* 



Annual, biennial or perennial herbs. Leaves alternate, entire or variously lobed and 

 dissected, often disposed in a basal rosette. Flower solitary on slender pedicels in the leaf 

 axils or in paniculately branched or thyrsoid inflorescences or congested in glomerules or 

 sessile in capitate heads. Calyx-lobes usually equal, cleft nearly to the base and often 

 flanked on the margins by a membrane, that of adjoining sepals often uniting to form a 

 pseudotube which becomes distended or ruptured by the growing capsule. Corolla funnel- 

 form to salverform, usually regular, blue, pink, red, yellow, or white. Stamens inserted 

 on the corolla-tube or the throat, often in the sinuses of the corolla-lobes, usually equal, 

 sometimes unequally inserted and unequal in length. Capsule 3-celled, the valves remain- 

 ing joined at the base and campanulately spreading on dehiscence. Seeds usually several 

 to many in a locule, rarely 1 or 2. [Named in honor of Filipe Luis Gil, a Spanish botanist.] 



A New World genus of about 40 species, most highly developed in California. Type species, Cilia laciniata 

 Ruiz & Pav. 



Plants perennial or biennial (see also G. Ripleyi). 



Corolla red, rarely pink or yellow, 20-30 mnu long; inflorescence a thyrsoid panicle. 



I. G. aggregata. 



Corolla white, 6-10 mm. long; inflorescence capitate congested. 2. G. congesta. 



Plants annual (except G. Ripleyi). 



Flowers in leafy-bracted glomerules at the ends of long naked branches, sometimes the lower solitary in the 

 axils; plants spreading or prostrate. 

 Leaves pinnatifid; flowers all in terminal clusters. o. G. polycladon. 



Leaves entire or irregularly toothed; the lower flowers solitary in the leaf-axils. 



4. G. depressa. 

 Flowers in panicles or heads or solitary in the axils of the leaves. 



Corolla funnelform or salverform. 



Flowers usually in well-differentiated inflorescences, usually not scattered and not solitary in the 

 leaf-axils, although sometimes the inflorescence leafy-bracted. 



Ovules solitary in the locules, rarely 2 to a locule; stamens unequally inserted on a long nar- 

 row throat. 5. G. gilioidcs. 

 Ovules several to many in each locule; stamens equally inserted on the tube or throat or in the 

 sinuses of the corolla-lobes. 

 Leaf-blades ovate or elliptic, the teeth aristate. 



Plant annual, corolla pink within, buff or white exteriorly. 



6. G. latifolia. 

 Plant perennial, corolla pink both within and without. 7. G. Ripleyi. 

 Leaf-blades variously pinnately lobed and dissected or cleft. 



Stems leafy, the cauline leaves becoming reduced only toward the apex; basal rosette 

 of leaves present or absent; flowers sessile to subsessile in capitate heads or in 

 few-flowered glomerules, sometimes solitary on slender pedicels. 



Corolla-lobes linear, rarely exceeding 1.5 mm. in width; flowers 6-8 mm. long, 

 sessile in dense, capitate inflorescences. 8. G. capitaia. 



Corolla-lobes oval, broader than 2 mm.; flowers 5-19 mm. long, sessile or sub- 

 sessile in capitate inflorescences or in few-flowered glomerules, sometimes 

 solitary on slender pedicels. 



Membrane of pseudotube usually colorless, broader than calyx-lobes; corolla 

 pale violet to deep blue-violet throughout; inflorescence S-SO-flowered, 

 rarely fewer; calyx-lobes acuminate, recurved in flower. 



9. G. achillcaefolia. 



Membrane of pseudotube always purple, narrower than calyx-lobes; corolla 

 blue to violet, with yellow tube and base of throat, and often 5 irregu- 

 lar purple spots in upper throat; inflorescence 1-S-flowered; calyx- 

 lobes acute, erect, not recurved in flower. 



Corolla 5-13 mm. long, just exceeding to 2 times as long as calyx; throat 

 narrow, yellow or often bearing 5 purple spots. 



10. G. miilticaulis. 



Corolla 10-19 mm. long, at least twice as long as calyx; throat broadly 

 expanded, always bearing 5 purple spots or a purple ring. 



II. G. tricolor. 



Stems usually not conspicuously leafy; cauline leaves much shorter than the basal; 

 basal rosette of leaves prominent; flowers long- or short-pedicellate, in few- to 

 many-flowered panicles. 



Basal leaves soft-pubescent with fine curled hairs or glabrous. 



Cauline and basal leaves with slender rachis and narrowly linear lobes which 

 are 2 to several times as long as the rachis is broad, or the basal leaves 

 simple, pinnately toothed or occasionally bipinnate, the lobes linear. 

 Calyx longer than corolla-tube, and at least one-half as long as corolla. 



12. G. ochroleuca. 



Calyx exceeded by corolla-tube, and less than one-half as long as corolla. 

 Inflorescence open-paniculate, the branches widely divaricate; co- 

 rolla-throat abruptly expanded and full ; corolla-tube pale 

 violet or yellowish. 13. G. Abramsii.
