» Racemes panicled, leafy-bracteate only at base, minutely bracteate or bractless above: slender 

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

 and at length redexed under it: soar of tlie nutlets ovate ur triangular, medial or infra-medial: 

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

 not hispid. 



M— Corolla short-funnelform (blue) ; the tube surpassing the calyx, about the length of the lobes. 

 i-E. difFdsmn, LehlU. 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 tlie bright blue corolla from half 

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

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

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

•)— +-' Coro^prmtate(tTom blue to nearlj- white); its tube shorter than the calyx and the lobes. 



" B. 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.

 "B. deflexum, Lehm. 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, &

 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. Jloribundum. (.Siberia to Eu.) 

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

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

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

 lanceolate bracts : loosely 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. — .l/yKods Mrginiana, L. Spec. ISO.

# * Spikes leafy-bracteate : pedicels erect or merely spreading, stout, shorter than the calj-x : 

 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, occup^-ing most of the ventral 

 angle, correspondmg with the subulate g^-nobase : annuals, with rough or hispid pubescence : 

 leaves linear, lanceola'te, or the lower somewhat spatulate. 



E. Lappcla, Lehm., 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 tlistinct 

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

B. Redowskii, Lehm.., l. c. 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.
