180 POLEMONIACEAE 



the leaves often merely toothed; cauline leaves reduced and bract-like or the lowermost similar 

 to the basal; flowers loosely eymose-paniculate, borne on slender pedicels; calyx 1 to 2 lines long, 

 equaling corolla-tube to % or V^ as long, its teeth broadly lanceolate to triangular, usually very 

 acute, its tube with scarious intervals between the ribs ; corolla white to blue, purple, pink or red, 

 funnelform, 2% to 4 lines long, its tube equaling the throat to twice as long; corolla limb 1 to 2 

 (or 2%) lines broad. — Open sandy or clay valleys, flats and hillslopes, chiefly transmontane, 10 

 to 5000 (or 8000) feet: northern Colorado Desert; Mohave Desert and mountains on its north 

 side; San Joaquin Valley and its bordering westerly hills; southern Sierra Nevada in Kern Co.; 

 east side of the Sierra Nevada from Inyo Co. to Modoc Co. North to eastern Oregon and eastern 

 Washington, east to Colorado, south to Mexico. Apr.-July. 



The prevailing phase of var. sinuata (Gilia inconspicua Dougl.), here treated as almost wholly 

 transmontane and enjoying a very wide range, is a plant mth compact basal leaf rosette and 

 naked or nearly naked stems, the cauline leaves mostly reduced or bract-like, the corolla-tube 

 once to twice as long as the calyx. In plant size, in leafage, in inflorescence and in flower color 

 and size it is more variable, perhaps, than any other named variety in this group. The stems 

 usually branch low and the flowering commonly begins low, whereas in var. exilis the flowering 

 panicle tends to be elevated above the basal rosette on a naked stem. In the transmontane deserts, 

 var. sinuata is abundant and has developed an almost endless number of localized strains. 



The following citation of stations indicates the wide geographic range of what is here assem- 

 bled under this name, Gilia tenuiflora var. sinuata. Although so highly variable a subgroup, an 

 attempt has been made to include: (a) only plants with small corollas in which the tube is not 

 esserted from the calyx or only slightly exceeds it (rarely twice as long) ; and (b) for the most 

 part plants with leaves once pinnately di\dded, the segments narrow and entire or sometimes short 

 and toothed. Such plants approximate topotypes of the original Gilia sinuata Dougl. from the 

 inner Columbia River region. For California, mainly transmontane collections from the Mohave 

 Desert and along the east side of the Sierra Nevada to Modoc Co. are cited below, but a small- 

 flowered form also occurs in the San Joaquin Valley.

Var. cana (Jones) Jepson comb. n. Plants 2^/2 to 8 inches high, the stem stout, solitary but 

 often branched low, glandular-puberulent ; leaves % to IV2 inches long, typically very white- 

 woolly, the blades pinnately divided into ovatish lobes, the lobes erenate, cuspidate ; panicle small ; 

 corolla 6 to 9 (or 12) lines long, the limb and slender tube probablv blue and throat yellow. — East 

 slope of the Sierra Nevada, 7000 to 10,000 feet: Inyo Co. (Nine-mile Caiion, C. N. Smith 158; 

 Cottonwood Creek, Jepson 928; near Lone Pine, Jones; Guadalupe Caiion, S. W. Aiistin 453) ; 

 Alpine Co. (Ebbett Pass, ace. Eastwood) . This variety is, perhaps, no more than a densely woolly 

 form of var. latiflora, but it has a definitely exclusive and highly localized distribution. 



Var. latiflora Gray. Plants 4 to 14 inches high, usually bushy or diffuse and usually of 

 shorter stature than the species, the stems glandular-pubescent or puberulent or glabrous, pa- 

 niculately branched above, usually very floriferous but the flowers borne singly (not condensed 

 in close clusters or less commonly) ; leaves tomentulose or glabrate; calyx glandular-pubescent or 

 glabrous, 1 line long ; corolla blue, purple or lavender or pink, 4 to 6 or 7 lines long, its tube little 

 exceeding the calyx or often varying to 3 times as long, gradually passing into the usually narrow 

 throat, the limb 2 to 5 lines mde; corolla-throat wliite, often with yellow zone; corolla-limb 3 to 

 4 lines wide. — Plains and mesas, 2000 to 6000 feet: Inyo Co.; Tulare and Kern Cos. in the Sierra 

 Nevada; Mohave Desert; Colorado Desert. Apr.
