 Echinospermum. BORRAGINACE^E. 529 



15. E. fulvocanescens, Gray. 1. c. Differs from the preceding in the peren- 

 nial csespitose roots, softer silky-strigose hairiness of the leaves, and ferrugineous- 

 yellow hairs of the calyx : tube of corolla longer than the calyx, twice or thrice the 

 length of its own lobes (limb 3 or 4 lines in diameter) : nutlets granulate-rough- 

 ened. E. glomeratum, var. (?) fulvocanescens, Watson, 1. c. 



High mountains of Nevada, to New Mexico and Wyoming. Intermediate in aspect between 

 the last and the next. 



16. E. leucophaeum, A. DC. Perennial, and almost woody at base, a span to 

 a foot high in tufts, silvery-canescent and somewhat strigose : leaves lanceolate and 

 linear, acute : spicate-glomerate inflorescence and calyx hirsute and hispid with 

 whitish or yellowish hairs and slender bristles : tube of the (cream-colored or yel- 

 low!) corolla exceeding the calyx and twice or thrice the length of its lobes : style 

 very long : nutlets whitish, ivory-like, smooth and polished (1 to 2 lines long). 

 Myosotis leucophcea, Dougl. in Hook. 1. c. t. 163. 



Dry and barren interior region, from British Columbia to Southern Utah, reaching the bor- 

 ders of California near Mono Lake, Brewer. 



* * * * Nutlets narrowly ovate, affixed by their whole length to the subulate gyno- 

 base by a very narrow groove having a more or less widened base, one of them 

 ivithout lateral angles (as in 9 <* 10), the other three with their lateral angles 

 extended into a continuous broad and somewhat crenate or pectinate wing, rarely 

 all four winged. 



1 7. E. pterocaryum, Torr. Slender annual, hirsute, loosely branching : leaves 

 linear or the lowest spatulate : flowers in naked and mostly bractless geminate or 

 cymosely clustered spikes : calyx-lobes oblong or in fruit ovate, enclosing the nut- 

 lets : corolla minute, barely a line long. Bot. Wilkes Exp. 415, t. 13 B ; Watson, 

 Bot. King Exp. 245. 



Eastern side of the Sierra Nevada (Anderson, Watson, Lemmori), and through the dry interior 

 region, from the borders of British Columbia to New Mexico and the borders of Texas. Nutlets 

 a line and a half long ; the wing on either side as wide as the body, usually merely toothed, in 

 var. pcctinatum cut half-way down into narrow and crowded linear-oblong lobes. 



8. ECHINOSPERMUM, Swartz. STICKSEED. 



Calyx 5-parted, persistent, spreading or reflexed in fruit. Corolla short-salver- 

 form and with conspicuous arching crests at the throat. Short filaments, style, 

 ovary, &c., as in Eritrichium. Nutlets 4, erect, attached by their ventral angle for 

 most of their length to a subulate or broadly pyramidal gynobase, the sides sur- 

 rounded by one or more rows of rigid prickles with backwardly barbed (glochidiate) 

 tips, either distinct or confluent into a border or wing, the back unarmed or some- 

 times similarly prickly, forming a bur, which is carried in the wool and hair of 

 animals. DC. 1. c. 



A genus of about 30 species, mostly rather coarse and small- (blue- or rarely white-) flowered 

 weedy plants, abounding through Northern Asia, a few reaching Europe, one of which, E. Lap- 

 pula, is a naturalized weed throughout the Atlantic United States. We have also two or three 

 indigenous species. 



1. E. Redowskii, Lehm. Annual, roughish hirsute, a span to a foot or two 

 high, much branched : leaves linear, lanceolate, or the lower somewhat spatulate, 

 obtuse ; the upper becoming bracts of the loose leafy spikes : pedicels erect or 

 merely spreading, stout, shorter than the narrow and at length unequal lobes of the 

 calyx, which mostly exceed the fruit : corolla small, a line or two long, blue : nut- 

 lets bordered by a single row of subulate barbed prickles, their bases often broad- 

 ened and more or less confluent ; the back and sides thickly beset with irregular 

 sharp points or tubercles ; scar and gynobase sleiuler. E. Redowskii, var. occiden-
