Gilia. POLEMONIACE^E. 489 



3. GILIA, Ruiz & Tav. 



Corolla funnelform, salverform, or sometimes short-campanulate or rotate, regular. 

 Stamens equally inserted in the tube or throat of the corolla ; the mostly slender 

 filaments sometimes unequal in length, not declined. Ovules and seeds several or 

 few or rarely solitary in each cell. Seed-coat, with few exceptions, mucilaginous 

 when wetted, and in many with uncoiling spiral threads. Herbs or suffrutescent 

 plants ; with either opposite or alternate and simple or compound leaves, many 

 species with showy flowers. 



A somewhat polymorphous genus, of nearly 70 species, belonging to the United States west of 

 the Mississippi, excepting one species to the east of it and two or three in extra-tropical South 

 America : several cultivated for ornament. Our species blossom in spring, except in the higher 

 mountains. 



I, All or most of the leaves opposite at least on the main stems, sessile and palmately 

 parted or rarely entire. (Seeds more or less mucilaginous in water, but with no 

 spiral threads.) 



1. Corolla from short-funnelform to almost rotate ; the lobes obovate : filaments 

 slender : anthers oval : ovules many or sometimes few in each cell : low or 

 slender loosely and mostly small-flowered annuals : the leaves with divisions 

 filiform or setaceous, appearing as if whorled, or in the last species entire. 

 DACTYLOPHYLLUM, Benth. ( Dactylophyllum & Dianthoides, Benth.) 



* Floivers short-pedicelled or almost sessile in the forks of the stem : corolla campan- 



ulate, its lobes entire : leaves ^-parted. 



1. Gr. demissa, Gray. Diffusely much branched, rather rigid, barely a span 

 high, profusely-flowered : lobes of the leaves acerose, half an inch long : lobes of 

 the 5-parted calyx subulate, scariously margined below, unequal, the longer equal- 

 ling the white 5-lobed corolla : stamens included : ovules few in each cell. Proc. 

 Am. Acad. viii. 263. 



Southeastern borders of the State, near Fort Mohave, Dr. Cooper. Also Southern Utah, Mrs. 

 Thompson, Parry. Upper leaves often alternate. 



* * Floivers on capillary or filiform pedicels, loosely paniculate : corolla from rotate 

 to short-funnelform, its lobes entire : leaves 3 - 1 -parted, those of the branches fre- 

 quently alternate. 



2. G. liniflora, Benth. Erect, or at length diffuse, in the largest forms a foot 

 and a half high, almost glabrous : divisions of the leaves nearly filiform, Spurrey- 

 like, about an inch long : flowers loosely panicled : corolla white, rotate when fully 

 open, from 10 to 6 lines in diameter, twice or thrice the length of the calyx, 

 5-parted down to the very short tube : filaments pubescent at base : ovules 6 or 8 

 in each cell. Bot. Mag. t. 5895. 



Var. pharnaceoides, Gray, is similar except in the reduced size, in the smaller 

 forms a span high, with capillary branches : the (sometimes pale flesh-colored) 

 corolla about 4 lines in diameter. G. pharnaceoides, Hook. Fl. ii. 74, t. 161. 



Not rare through the western part of the State, in both forms : the small variety extending to 

 Oregon and Utah. 



3. Gr. pusilla, Benth. Small, 2 to 6 inches high, at length diffuse, often 

 scabrous-puberulent : divisions of the leaves filiform-subulate or acerose, less than 

 half an inch long, shorter (mostly much shorter) than the scattered capillary pedi- 

 cels : corolla nearly white, or purplish with yellow throat, between rotate and short- 

 funnelform ; its lobes broadly obovate : filaments nearly glabrous at base : ovules 3 

 to 5 in each cell. Corolla 1 to 2 lines long and little exceeding the calyx, in the 

 form answering to the Chilian species.
