NAVARRETiA POLEMONIACEAE 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 Steud. 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. Suksdorfii. 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 in dense globular heads, 

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

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

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

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

 oblong. Low grounds, Falcon Valley, Klickitat Co., Washington. Dis- 

 tributed by Mr. Suksdorf as Gilia minima, from which it differs in its 

 dense heads and 3-lobed calyx-teeth. , 



N. minima Nutt. 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. 



N. 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 aciculan-sub- 

 ulate divisions : flowers in lax glomerules ; 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. 



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

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

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

 sions slender-spinulose : flowers in rather small heads, the subtending 

 bracts with barely pungent divisions : calyx-tube contracted at the sinuses, 

 about equalling the subulate entire lobes : corolla white, longer than the 

 calyx : stamens 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. Stein 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 heads 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 : 

 rather stout 6-8 inches high, very rigid, especially the leaves and bracts ;
