9. N. lobbii Gray. (Fig. 407.) White-woolly plant; stems creeping, woody, 

 bearing many ascending branches 3 to 8 inches long ; leaves entire, of 2 kinds, those 



of the vegetative shoots rather crowded, dark 

 green, their blades linear or nairow-oblaneeo- 

 late, more or less revolute, % to 1 inch long, 

 sessile, with a short branchlet or dense fascicle 

 of smaller leaves in the a'^rils ; leaves of the 

 flowering shoots scattered, their blades oblan- 

 ceolate to spatnlate, white-wooUy beneath, 

 densely villous above, 1 to 2^4 inches long, 

 narrowed to base bnt scarcely petioled; flow- 

 ering shoots bearing sessile or shortly pe- 

 dnneled clusters of flowers in their uppermost 

 axils ; calyx-lobes narrowly linear, ^2 as long 

 as corolla ; coroUa purple, narrow-funnelf orm. 

 4 to 5 lines long; ovary densely and style some- 

 what hairy; ovules 2 to 8 to each placenta; 

 capsule 4 to 14-seeded, the seeds large (34 line 

 long) , densely papillate. 



Rocky, sandy or red-volcanic soil of slopes 

 and ridges. 4000 to 7000 feet: North Coast 

 Ranges in Trinity Co. and southwestern Sis- 

 kiyou Co. ; northern Sierra Nevada from El- 

 dorado Co. to Shasta Co. East to western 

 Nevada. June-July. 



Morphological note. — The leafy shoots or branch- 

 lets are of two kinds. Tegetative shoots and flowering 

 shoots. The vegetative shoots bear glandular and 

 dark green narrow leaves. The flowering shoots arise 

 terminally the next year from the vegetative branehlets and bear whitish leaves that are of a dif- 

 ferent shape and are broader. The two types of foliage shoots thus appear in regular alternation. 

 The running rootstoeka, 1 to several feet long, give rise to colonies. 



The corolla-tube is angled in full anthesis. in the bud it is deeply grooved outside opposite 

 the corolla sinuses (between the rounded angles of the tube) . In these grooves of the coroUa-tube 

 the slender ealyr-lobea lie. The included stamens, 3 long and 2 short, are adnate at base of eoroUa- 

 tube for 1 line, the adnate part of the filament strongly in relief and very narrowly winged on 

 both sides. The capsule is first loculicidally, then septieidally dehiscent, which is a character of 

 the genus Eriodietyon. This species is, thus, a connecting link between Xama and Eriodictyon and 

 on technical grounds rests about as well in one genus as the other.
