 Rocky Mountains of Golorado, Utali, and Wyoming, and nortli-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 Eeldnospermuin if retrorse. The Rocky Mountain 

 plant is very near the P]uropean, but whiter-viilous. The form on the N. W. coast moi'e 

 sparsely and less softly villous, passing into 



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. Ciianussonis, 

 DC. 1. c. Myosotis villosa, Cham. 1. c. — Island of 8t. Paul. (Adjacent Asia.) 



* * (Myosotidea.) Nutlets not appendaged, ovate, oblong, or trigonous: low and mostly diffuse 

 or spreading annual^^ (in Soutli America some perennials), sparsely or minutely iiirsute : leaves 

 linear; tlie lower comniunly opposite : Howers white, some bracteate, otliers racemose or spicate 

 and bract less. 



-K- Flowers ver\' small : corolla only a line long ; the folds or appendages iu its throat inconspic- 

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



E. 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 foliaceous-accrescent : nutlets ovate-trigonous, a 

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

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

 plebeium, Cham. & Schlecht. in Linn. iv. 44G. — Aleutian Islands, Chainisso, Uarrimjton. 



E. Californicum, 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 

 accompanied by leaves or bracts, at length scattered : calyx lax or open in fruit : nutlets 

 ovate-oblong, transversely rugose and minutely scabrous or smooth, small ; the scar almost 

 basal. — Prodr. x. 180 ; Watson, Bot. King, 242. Myosotis Californica, Fisch. & Meyer, Ind. 

 Seni. Petrop. 18o5. — Springy or muddy ground, through California and Oregon to New 

 Mexico and Wyoming. Passes into 



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. 52(5. — E. California to Wyoming and Colorado. 



+ — H- Corolla surpassing the calyx, with comparatively ample limb 2^ to 4 or even 5 lines in 

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

 puberulent: inflorescence more racemose: nio^^t of the lower leaves opposite, merely sparsely 

 hirsute : calyx when young often ferrugineous-hirsute. 



E. Scouleri, A. DC. Slender, mostly erect, a sjjan 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 

 long: calyx erect in fruit: nutlets rugulose, glabrous, half line long; the scar small. —

§ 2. Plagiop.otiirys, Gray, 1. c Nutlets broadly ovate-trigonous, incurved 

 (the narrowed tips conniving over tlie short style), rugose, attached by the middle
