 var. aretioides, Gray in Proc. Acad. Philad. 1863, 73 ; Watson, Bot. King, 241. Myosotis 

 nana, Torr. in Ann. Lye. N. Y. ii. 225. M. aretioides, Cham, in Linn. iv. 443. — Highest 

 Rocky Mountains of ("olorado, Utah, and Wyoming, and north-west arctic coast and 

 islands. Teetli 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. Tlie Rocky Mountain 

 plant is very near the P^uropean, but whiter-vilious. The form on the N. W. coast more 

 sparsely and less softly villous, passing into 



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

 on tlie stems, and tlie grey liairs commonly witli papillose-dilated base. — E. Chamissonis, 

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



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

 or spreading annuals (in South America some perennials), sparsely or mhiutely hirsute: leaves 

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

 and bractless. 



•1^ Flowers very small: corolla only a line long; the folds or appendages in its throat inconspic- 

 uous and smooth : 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 ventrally down to the 

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

 plebeium, Cham. & Schlecht. in Linn. iv. 446. — Aleutian Islands, Chamisso, Harrington. 



E. Calif ornicum, 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. 130 ; Watson, Bot. King, 242. Myosotis Californica, Fisch. & Meyer, Ind. 

 Sem. Petrop. 1835. — Springy or muddy ground, through California and Oregon to New 

 Mexico and Wyoming. Passes into 



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

 spatidate: 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. 



•i ^1— 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 j'ellow- 

 puberulent : inflorescence more racemose : most of the lower leaves opposite, merely sparsely 

 hirsute : calyx when young often ferrugineous-hirsute. 



E. Scouleri, 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 

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

 Chorisianum, plebeiutn, & part of Californicum, Gray in Proc. Am. Acad. viii. 397. — Compara- 

 tively dry soil, W. Oregon and California. Seems to pass into the next. 



B. Chorisianum, DC. At first erect, soon diffusely spreading or decumbent: larger 

 leaves 2 to 4 inches long: flowers in lax usually solitary racemes, many of them leafy- 

 bracted : pedicels spreading, sometimes filiform and 2 to 9 lines long, sometimes even 

 shorter than the calyx : corolla more funnclform, its ample limb 3 to 5 lines in diameter : 

 nutlets (half line long) minutely rugose-tuberculate ; the scar narrow. — Gray, Proc. Am.

 coast and the bays of Monterey and San Francisco. 



§ 2. Plagiobothrys, Gray, L c Nutlets broadly ovate-trigonous, incurved 

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

 of the concave or seemingly hollowed ventral face to a globular or short-conical 

 gynobase, by means of a salient caruncle-like portion, which at maturity separates
