196 BORRAGmACE^E. Eritrichium. 



+- Tube of the corolla not longer than the calyx and little if any longer than the lobes; a ring of 

 10 small scales or glands above the base within : anthers oval or oblong : style rather short. 



++ Nutlets margined all round with a firm entire wing : plant setose-hispid ; corolla small. 

 B. holopterum, Gray. About a foot high, perhaps from an annual root, loosely pan- 

 iculate-branched, rather slender : leaves linear, an inch or so long, very rough with the 

 papilliform bases of the rigid short bristles • paniculate spikes rather few- and at length 

 loosely flowered: calyx and corolla about a line (and the former becoming 2 lines) long: 

 immature nutlets ovate-trigonous, a line long, muriculate on the convex back, abruptly 

 wing-margined (the wing nearly the breadth of the dorsal disk), attached for nearly the 

 whole length to the conical-subulate gynobase. — Proc. Am. Acad. xii. 81. — Ehrenberg, 

 Arizona, Palmer. 



"E. setosissimum, Gray. Stem robust, 2 feet or more high from an apparently biennial 

 root, nearly simple, very hispid (as is the whole plant) with long and stiff hut slender 

 spreading bristles (with or without papilliform base), also cinereous with fine spreading 

 hairs : leaves lanceolate-spatulate, the lower 4 or 5 inches long (including the tapering base 

 or margined petiole) : spikes in fruit elongated (3 or 4 inches long), dense and strict in a 

 naked thyrsus : corolla 2 or hardly 3 lines long : anthers on short and thickened inflexed 

 filaments ; fructiferous calyx fully 3 lines long ; the lobes oblong-lanceolate, carinate by a 

 strong midrib : nutlets obcompressed, almost 3 lines long, broadly ovate in outline, dull, 

 merely scabrous on the back ; the conspicuous wing much narrower than the disk and ex- 

 tended round the base ; the scar narrow at base : gynobase elongated-subulate. — Proc. 

 Am. Acad. 1. c. — Shores of Fish Lake, Utah, at the elevation of 8,700 feet, L. F. Ward. 

 Known only in fruiting specimens, which so much resemble E. glomeratum, var. virgatum, 

 that intermediate forms may occur, and the great size, flatness, narrow-based scar, and con- 

 spicuous wing of the nutlets may prove inconstant. 



•H- ++ Nutlets acutely triangular, wingless. 



' B. Jamesii, Torr. A span or two high from a perennial root, rather stout, branched 

 from the hard or lignescent base, canescently silky-tomentose and somewhat hirsute, be- 

 coming strigose-hirsute or even hispid in age : leaves oblanceolate or the upper linear, 

 obtuse : spikes somewhat panicled or thyrsoid-crowded, moderately elongating, bracteate : 

 limb of the short and broad corolla about 3 lines wide : fruiting calyx mostly closing over 

 the depressed-globular fruit, which consists of 4 closely fitting very smooth and shining 

 broadly triangular nutlets (hardly higher than wide). — Marcy Rep. 294, & Bot. Mex. Bound. 

 140 ; Gray, 1. c. E. muUicmde, Torr. 1. c, a more hispid form. Myosotis suffruticosa, Torr. 

 in Ann. Lye. N. Y, ii. 225. — Plains and sandy shores, western borders of Texas and New 

 Mexico to Arizona and Wyoming. — Nutlets almost exact quarters of a sphere, or with 

 angles more acute and sides rather concave, attached by the inner angle, also with a 

 short transverse scar at base. 



"■E. glomeratum, DC. A span to a foot or more high from a biennial root, greyish-hirsute 

 and hispid : leaves spatulate or linear-spatulate : inflorescence thyrsiform and mostly dense ; 

 the short and often forked lateral spikes at length commonly exceeding the subtending 

 leaves : calyx very setose-hispid : limb of the corolla 3 to 5 lines in diameter : the crests 

 truncate : nutlets forming an ovoid-pyramidal fruit ; each triangular-ovate, sparsely more 

 or less tuberculate-rugose on the back (a line long), with sharp lateral edges, and sulcate 

 ventral angle extending into a broad basal scar. — Watson, Bot. King, 242, t. 23 ; Gray, 1. c. 

 Cynoghssum glomeratum, Pursh, Fl. ii. 729. Myosotis glomerata, Nutt. Gen. i. 112 ; Hook. Fl. 

 ii. 82, 1. 182. Rochelia glomerata, Torr. Ann. Lye. N. Y. 1. c. ; Nutt. in Jour. Acad. Philad. vii. 

 45. E. glomeratum, vilt. hispidissimum, Torr. Bot. Mex. Bound. 140, may be taken for nearly 

 the original of Nuttall and Bradbury, of the Upper Missouri. — Plains of S^katchewan 

 to New Mexico and Utah. Two varieties mark the opposite extremes. 



— =" Var. humile, Gray. Barely a span high, often tufted on an apparently perennial 

 root : pubescence less hispid and generally cancscent, at least the lower leaves ; these 

 spatulate, an inch or more long : thyrsus spiciform : pubescence and bristles of calyx 

 either whitish or tawny yellow. — Proc. Am. Acad. x. 01. — Rocky Mountains from the 

 British Boundary to Utah, at 8000 feet, and higher parts of the Sierra Nevada, California. 

 Passing on one hand into the typical form, on the other approaching the next species. 



Var. virgatum, Porter. Very hispid, not at all canescent : stem strict, a foot or 

 two high, flowering for most of its length in short and dense nearly sessile clusters, which
