Echinospermum. BORRAGINACE^E. 189 



* Racemes panic-led, leafy -bracteate onlj' at base, minutely bracteate or bractless above: slender 

 pedicels recurved or deflexed in fruit : calyx-lobes lanceolate or oblong, shorter than the fruit, 

 and at length refiexed under it: scar of the nutlets ovate or triangular, medial or infra-medial: 

 gynobase short-pyramidal : biennials or annuals, some perhaps perennials, pubescent or hirsute, 

 not hispid. 



*- Corolla short-fiinnelforin (blue) ; the tube surpassing the calyx, about the length of the lobes. 

 E. diffusum, Lelim. A foot or so high : leaves oblong-lanceolate ; or the lowest spatu- 

 late, narrowed at base into long wing-margined petioles ; the upper sessile, from oblong- 

 lanceolate to ovate or cordate, passing into small bracts : racemes commonly loose and 

 spreading : fruiting pedicels 3 to 5 lines long : limb of the bright blue corolla from half 

 inch in diameter to much smaller : style slender: fruit a globose bur; the nutlets 3 lines 

 long, densely nuiriculate-scabrous, rather sparsely armed throughout with long and flat- 

 tened prickles ; the scar large and broadly ovate : gynobase broadly pyramidal. Pug.

 deflexnm, \ar.floribitndnin, Gray, Bot. Calif, i. 541, in part. Open woods, &e., Oregon, and 

 California, along the Sierra Nevada, where it is common. 



4 -t Corolla rotate (from blue to nearly white); its tube shorter than the calyx and the lobes. 



E. floribundum, Lelim., 1. c. Rather strict, 2 feet or more high, or sometimes smaller : 

 leaves from oblong- to linear-lanceolate ; the lowest tapering into margined petioles : 

 racemes numerous, commonly geminate and in fruit rather strict : nutlets with elongated 

 triangular back naked (2 lines long), merely scabrous ; and the margin armed with a close 

 row of flat subulate prickles, their bases often confluent; scar smaller and narrowly ovate.

 1. c., mainly. E. subdecitmbens, Parry in Proc. Davenport Acad. i. 148, a small form, said to 

 be perennial. Lake Winnipeg to British Columbia, and south to New Mexico and Cali- 

 fornia. Limb of corolla varying from 2 to 5 lines in diameter. 



E. deflexum, Lelim. Diffusely branched, a foot or so high : leaves from oblong to 

 lanceolate : racemes lax, loosely paniculate : flowers soon sparse, smaller than in the pre- 

 ceding : nutlets smaller, and the mostly naked back (a line long) broader. Asper. 120, &

 katchewan, and Winnipeg Valley, Druminoiid, Bourgeau. Brit. Columbia, Li/ull. Habit 

 intermediate between the preceding and following ; the American specimens having occa- 

 sionally some few prickles developed from the rough-granulate dorsal face of the nutlets. 

 Fruit as well as flowers about half the size of that of E. floribundum. (Siberia to Eu.) 



E. Virginicum, Lelim., 1. c. Stem 2 to 4 feet high, erect, with long and widely spread- 

 ing branches : radical leaves round-ovate or cordate, slemler-petioled ; cauline (3 to 8 inches 

 long) ovate-oblong to oblong-lanceolate, acuminate at both ends; uppermost passing into 

 lanceolate bracts : loosety paniculate racemes divaricate, filiform : pedicel and flower each 

 about a line long : corolla slightly surpassing the calyx, pale blue or white : fruit globular, 

 2 lines in diameter, armed all over with short prickles. Myosotis l r injiniana, L. Spec. 189.

* * Spikes leaf y-bracteate : pedicels erect or merely spreading, stout, shorter than the calyx: 

 lobes of the latter little shorter than the small corolla, becoming foliaceous and often unequal, 

 mostly exceeding the fruit : scar of the nutlets long and narrow, occupying most of the ventral 

 angle, corresponding with the subulate gynobase: annuals, with rough or hispid pubescence: 

 leaves linear, lanceolate, or the lower somewhat spatulate. 



E. LAPPULA, Lelim., I.e. Erect, a foot or two high, branched above; nutlets rough-granu- 

 late or tuberculate on the back, the margins with a double row of slender and distinct 

 prickles, or these irregular over most of the back. Fl. Dan. t. 692. Waste and culti- 

 vated grounds, from the Middle Atlantic States to Canada. (Nat. from Eu.) 



E. Redowskii, Lehni., I.e. Erect, a span to 2 feet high, paniculately branched: nut- 

 lets irregularly and minutely muricately tuberculate; the margins armed with a single 

 row of stout flattened prickles, which are not rarely confluent at base. Gray, Proc. Acad.
