§ 2, Nutlets ovate-triquetroas, straight, at maturiti/ ivhitish, smooth and polished, 

 attached by the louver part of the sharp inner angle, the scar narrow, all three 

 faces fiat or nearly so. 



6. A. vernicosa, Hook. <fe Ai-u. Sparsely bristly, simple or loosely hranclied, a 

 foot or two high : Iraves from linear to ovate-lanceolate : corolla light yellow, 4 or 

 5 lines long, ami the limb 2 lines in diameter ; the tube longer than the liuear-lun- 

 ceolate calyx-lobes : nutlets shaped like a grain of buckwheat. 



Var. grandiflora, Gvaj. liobust, more hispid, and remarkably large-flowered ; 

 the more exserted and somewhat funnelform tube of the corolla nearly half an inch 

 long, and the ample limb broader : calyx-lobes often combined, so as to appear 

 as 3 or 4 : nutlets broader, and rather concave on the back. — A. grandifiora, Klee- 

 berger, ined. (Stamens low on the tube, and style very long, in the specimen ; 

 while in those know^n of A. vernicosa the stamens are borne in the throat.) 



Western part of the State, probably near Monterey, Coulter, Dourjlas. The remarkable variety, 

 which may be quite distinct, at Antioch, Kellogg. 



7. ERITRICHIUM, Sdirader. 



Calyx 5-parted and persistent (one species excepted), erect or closed in fruit. 



Corolla salverform with tube mostly short and not exceeding the calyx, with or 



without arching crests in the throat; the rounded lobes imbricated in the bud. 



Filaments short. Style short or sometimes long : stigma minutely capitate. Ovary 



of 4 lobes. Nutlets 4, or sometimes by abortion fewer, usually ovate and more or 



less triangular, coriaceous or cartilaginous, destitute of wings or appendages except 



in one species, attached by the inside of the base or some part of the ventral face 



or angle to a convex, pyramidal, or more elevated and even subulate receptacle 



(gynohase), which when slender is usually called the base of the style. — ISfostly 



hispid or hairy herbs, mainly annuals, with usually small or minute and either 



bracteate or bractless flowers, which are white in all our species, except No. 15 ; the 



leaves narrovr. — Gray, Proc. Am. Acad. x. 55. EritricMum, Plagiobothrys, & 



Krynitzkia, Fischer & Meyer ; A. DC. Prodr. Plptocalyx, Torr. 



A rather large genus, of N. America, N. Asia, &c., one extending into the Alps of Europe, a 

 few South American. The greater part of our species inhabit the region stretching from llupert's 

 Land to Texas and westward. 



§ 1. Nutlets attached by the inside of the base only to a slightly elevated receptacle : 

 small or loiv and diffuse or spreading annuals, more or less hh^sute, with linear 

 leaves, the lower ones oftener opposite: flowers with or without bracts : fruiting 

 calyx rather open, except in No. 2. 



1. E. Chorisianum, DC. Diffusely branching or at length decumbent stems a 

 span or two long : leaves broadly or narrowdy linear (1 to 3 inches long, 1 to 4 

 lines wide) : flowers loosely racemose, on spreading pedicels which are generally 3 

 to 5 times longer than the calyx, both yellowish-hirsute Avhen young : corolla with 

 lobes longer than its tube and much surpassing the calyx ; the limb 2 to 4 lines in 

 diameter ; yellow crests in the throat conspicuous : nutlets roughish, somewhat 

 keeled dowai the back. — Myosotis Chorisiana, Cham. & Schlecht. Eritrichium 

 connatifolium, Ivellogg, Proc. Calif Acad. ii. 103, fig. 51. 



Wet ground, shores of San Francisco Bay and south to Monterey. Known by the pedicels, of 

 which the earher and longer are usually half an inch long, but the later ones much shorter. 



2. E. Scouleri, A. DC. Slender, generally upright, a span to a foot high : 

 leaves narrow : flowers rather crowded in naked spikes (these often in paii-s), 

 the lowest leafy-bracted, the rest* bractless : pedicels very short and nearly erect,
