 Rocky Mountains of Colorado, Utah, and Wyoming, and north-west arctic coast and 

 islands. Teeth or spines of the nutlets not rarely with a few bristly points, so that they 

 would be glochidiate in the manner of Echinospermum if retrorse. The Kocky Mountain 

 plant is very near the European, but whiter-villous. The form on the N. W. coast' more 

 sparsely and less softly villous, passing iuto 



Var. Chamissonis, Herder, 1. c. A stouter form, with broader leaves imbricated 

 on the stems, and the grey hairs commonly with papillose-dilated base. — E. Chamissonis,

* * (Myosotidea.) Xutlpt^ not appendaged, ovate, oblong, or trigonous; low and mostly diffuse 

 or spreading annuals (in South -Vmerica some perennials), sparsely or minutely- hirsute: leaves 

 linear ; the lower commonly opposite : flowers white, some bracteate, others racemose or spicate 

 and bractless.

 uous and smooth : stems diffuse or decumbent, a span or so in length. 



B. plebeium, A. DC. Sparsely and minutely hirsute or glabrate : leaves lax (the larger 

 2 inches long and 2 lines wide) : flowers scattered, on pedicels shorter than the calyx, 

 which is open in fruit and the divisions foUaceous-accrescent : nutlets ovate-trigonous, a 

 line long, coarsely rugose-reticulated, glabrous, sharply carinate ventrally down to the 

 large ovate scar and dorsally only along the narrowish apex. — Gray, 1. c. Lithospermum

 "•E. Californiouin, DC. Slender, more or less hirsute: leaves mostly smaller and nar- 

 rower : stems flowering from near the base : flowers almost sessile, most or all the lower

Var. subglochidiatum, Gray. Slightly succulent : lower leaves inclined to 

 spatulate : nutlets when young minutely more or less hirsute or hispid, especially on the 

 crests of the rugosities, some of these little bristles becoming stouter and appearing glo- 

 chidiate under a lens! — Bot. Calif, i. 526. — E. California to Wyoming and Colorado. 



-1— -1— Corolla surpassing the calyx, with comparatively ample limb 2} to 4 or even b lines in 



diameter, therefore appearing 'rotate; the appendages in its throat conspicuous and yellow- 



puberulent; inflorescence more racemose: mo.st of the lower leaves opposite, merely sparsely 

 hirsute : calyx when young often ferrugineous-hirsute. 



— E. Soouleri, A.DC. Slender, mostly erect, a span to a foot high : leaves narrowly linear 

 (an inch or two long) : flowers in geminate or sometimes paniculate slender naked spikes, 

 most of them bractless : pedicels erect or ascending, from very, short to at most a line
