2. L. texana. 

 Perennials, the stems from a thick root-crown; racemes leafy-bracteate only at base, the bracts 

 above the base minute; calyx in fruit shorter than the pedicels; pedicels in fruit recurv- 

 ing or deflexed; nutlets united half-way up by the ventral keel to the pyramidal gynobase. 

 Dorsal face of the nutlets minutely papillate or naked or beset with a few very short (% to 

 % line) scattered prickles, its border armed mth a row of conspicuously flattened 

 prickles. 

 Eacemes several to many, borne in the leaf-asUs along the upper part of the stem and 

 thus forming a panicle ; blades of basal leaves long-oblong to lanceolate, oblan- 

 ceolate or linear, their pubescence dense or thin. 

 CoroUa blue, the limb 1^4 to 6 lines broad, the tube not exceeding the calyx. 



Corolla 3 to 4 lines broad ; marginal prickles of nutlets united at base to form 

 a narrow wing, rarely a few prickles distinct. 

 Herbage hispid with spreading hairs; stamens inserted about middle of 

 corolla-tube; corolla 4 lines broad; North Coast Ranges and 



Sierra Co 3. L. setosa. 



Herbage strigose or mostly so ; stamens inserted above middle of corolla- 

 tube; corolla 3 lines broad; transmontane in Lassen and Modoc 



Cos 4. L. arida. 



Corolla mostly 1% to 3 lines broad; stamens inserted on upper part of coroUa- 

 tube. 

 Leaves thinly soft-pubescent; corolla usually 2 to 3 (or 4) lines broad; 

 marginal prickles of nutlets united at base to form a narrow wing; 



Sierra Nevada and North Coast Ranges 5. L. florihunda. 



Leaves densely roughish-puberulent ; corolla l^^ to 2 lines broad; marginal 



prickles of nutlets distinct to base or nearly so ; White Mts 



6. L. coerulescens. 



Corolla white, the limb 6 to 9 lines broad, the tube 1% to 2 times as long as the 



calyx; stamens inserted on lower part of coroUa-tube; North Coast Ranges. 



7. L. iella. 



Racemes 2 or 3, terminal and nmbellately erect, or sometimes only 1; blades of basal 



leaves elliptic or elliptic-ovate, the scattered minute short hairs arising from 



minute dark dots ; Mt. Whitney region 8. L, sharsmithii. 



Dorsal face of the nutlets beset all over with prickles, the prickles 1% to 2% lines long at 

 maturity, less broadly dilated. 



Corolla white, the limb 3 to 6 lines broad, the tube not exceeding the calyx 



9. L. calif ornica. 

 Corolla blue or sometimes pink, the tube 1% to 2 times as long as the calyx. 



Limb of corolla 5 to 7 lines broad ; corolla-crests hairy ; leaves velvety -pubescent 



10. L. velutina. 

 Limb of corolla 3 to 4 lines broad; corolla-crests papillate-roughened but not hairy; 

 leaves thinly hispidulose, the hairs arising from minute dark pits or half- 

 craters _ 11. L. nervosa. 



1. L. redowskii Greene. Steins 1 or few from the base, erect or diffuse, panieu- 

 lately branched above, 8 to 14 inches high; herbage puberulent and spreading- 

 hirsute; leaf -blades linear to very narrowly lanceolate, % to li/4 inches long, sessile 

 or the lower and basal narrowed into petioles ^4 to as long ; racemes bracteate with 

 very small leaves ; calyx longer than the pedicels, the narrowly lanceolate segments 

 not recurved in fruit; corolla blue, II/2 to 1% lines long, the tube a little shorter 

 than the calyx, the throat with conspicuous crests ; stamens inserted about middle 

 of corolla-tube ; nutlets 1 to 1^4 lines long, the dorsal area ovate, sharply tubercu- 

 late, bordered by a single row of barbed prickles, the prickles distinct at base or 

 sometimes joined by a narrow margin.
