NAVARRETIA PO^MONIACEJE 457 



white-pubescent: calyx pubescent, the teeth all spinose- tipped and toothed, 

 very unequal : corolla pale blue, with filiform tube and funnelform throat ; 

 not exceeding the bracts : stamens about equalling the oblong corolla-lobes : 

 capsule obovoid few-seeded: seeds winged. Southwest Oregon. 



N. intertexta Hook. Fl. ii, 72. Gilia intertexta Sleud. Neither vis- 

 cid nor glandular: stem erect, simple or widely branched, 4-8 inches high, 

 rather stout; leaves nearly glabrous with divaricate acerose spinescent di- 

 visions sparingly divided or simple : flowers densely glomerate : tube of the 

 calyx and base of the bracts strongly villous with white spreading hairs ; 

 its unequal spinescent and entire lobes equalling the white corolla : ovules 

 and seeds 3-4 in each cell. In damp places, Brit. Columbia to California 

 and the Rocky Mountains. 



N. Snksdorfii. Low and depressed, or erect, 1-3 inches high, much 

 branched ; leaves linear, an inch or two long, entire or with a pair or two 

 of linear lobes near the base, not spinose: flowers m dense globular heads, 

 the subtending bracts bipinnate with spinose lobes : lobes of the calyx shor- 

 ter than the cylindraceous tube, which is but slightly contracted at the 

 sinuses; the smaller ones entire : corolla white, barely exceeding the calyx : 

 stamens as long as the corolla: capsule very thin, 3-seeded : seeds oblong. 

 Low grounds, Falcon Valley, Klickitat Co. Washington. Distributed by 

 Mr. Suksdorf. as Gilia minima, from which it differs in its dense heads and 

 3-lobed calyx-teeth. 



N. minima NuU. PI. Gamb. 160. Depressed, often forming broad 

 tufts, %-2 inches high glabrate: leaves acicular with simple and 

 few divisions: flowers in small loose heads the subtending bracts spinosely 

 pinnate : tube of the calyx white-hairy in the broad sinuses, as long as the 

 spinose entire lobes which equal or exceed the white corolla : ovules 1-3 

 in each cell : capsule oblong-obovate, attenuate below. Interior of Oregon 

 and Washington to Arizona and Nebraska. 



X. Breweri Greene 1. c. 137, Gilia Breweri Gray, Erect or at length 

 much branched and diffusely spreading, 1-10 inches high, very minutely 

 glandular-puberulent throughout : leaves with mostly simple acicular-sub- 

 ulate divisions : flowers in lax glonqerules ; the subtending bracts similar 

 to the leaves : tube of the calyx a line long, 2 or 3 times shorter than the 

 unequal entire lobes : corolla yellow, the slender tube equalling the calyx : 

 stamens and style equalling the oblong corolla- lobes : ovules 1 or 2 in each 

 cell. Southeastern Oregon to Wyoming, Nevada and California. 



X. leucocephala Benth, PI. Hartw. 160. Glabrous except some woolly 

 pubescence at the summit of the stem and scarious ralyx-tube: stem slen- 

 der, 4-10 inches high, seldom rigid: leaves soft, their often simple divisions 

 slender-spinulose : flowers in rather small heads, the subtending braci s with 

 barely pungent divisions : calyx-tube contracted at the sinuses, about equ- 

 alling the subula'e entire lobes: corolla white, longer than the calyx: sta- 

 mens exserted : ovules 2 in each cell. In wet places, southern Oregon to 

 California 



* * Leaves simply pinnatifid or incised or many of them entire. 



N. divaricata Greene 1, c. Gilia divaricata Torr. Stem slender, 1-6 

 inches high divaricately branched not glandular- viscid but glabrate : leaves 

 slender and filiform, or the upper with acerose divisions and passing into 

 the bracts of the small heais which are palmately 3-5-cleft: calyx woolly- 

 pubescent; the scarious tube much shorter than the unequal entire lobes : 

 corolla rather slender, 3-4 lines long ; the slender tube about equalling the 

 calyx-teeth: stamens included: ovules 5-7 in each cell. Washington to 

 California, in the high mountains. 



N. atractyloides H. & A. Bot. Beech. 368. Pubescent and very viscid :
