above passing into linear-subulate bracts : corolla greenish-white, less than 2 inches long, 

 somewhat contracted between the limb and the subclavately dilated throat ; the lobes 2 or 

 3 lines long, acute. — Dunal in DC. I.e. 569. — Damp grounds around Matamoras, Ber- 

 landier. Probably on the Texan side of the Rio Grande also. (Mex., W. Ind.) 

 N. repanda, Willd. Minutely pubescent or above glabrate, 2 or 3 feet high, with loose 

 slender branches, extending into open racemose or somewhat paniculate naked inflores- 

 cence : leaves thin (3 to inches long and 1 to 4 wide), ovate, or the lower obovate and 

 sometimes panduriform, commonly repand ; tlie lowest contracted into a winged petiole; 

 upper deeply cordate-clasping : bracts minute or often wanting : calyx-lobes slender, fully 

 as long as the short-campanulate acutely 10-ribbed tube : corolla with tube frequently 2 

 inches long, somewhat clavate or f unnelform at the open throat ; the spreading limb 

 white, or sometimes tinged with rose, 7 to 12 lines in diameter; its lobes short and obtuse 

 or acutish. — Lehin. Nicot. 40, t. 3 (depauperate) ; Dunal in DC. 1. c, but not Hook. Bot. 

 Mag. and perhaps not N. li/rata. HBK. N. pandurata, Dunal, I.e. N. Roemeriana, Scheele 

 in Linn. xxi. 707. — Low grounds, Texas. (Mex.) 



-i— -(— Leaves entire, or the margins sometimes obscurely imdidate: filaments slender, 



-i"i- Equally inserted low down on the tube of the salverform corolla, which is not enlarged at the 

 throat, and is very much longer than the small obtusely 5-lobed limb. 



= Leaves, even the lower, with more or less clasping base : flowers open throughout the day. 



N. trigonoph^Ua, Dunal. Viscid-pubescent : stem 1 to 8 feet high, simple or vir- 

 gately branched : leaves all sessile or only the lower tapering into a wingeil petiole, and 

 obovate-oblong ; the upper oblong-lanceolate with a broader cordate half-clasping base, or 

 some spatulate-lanceolate with a dilated auriculate-clasping base (1 to 4 inches long) : in- 

 florescence at length loosely paniculate-racemose, with the later bracts very small or want- 

 ing, and somewhat unilateral pedicels about the length of the calyx : calyx-lobes subulate- 

 lanceolate but rather obtuse, equalling the campanulato tube, attaining the middle of the 

 corolla-tube, about equalling the 4-valved capsule, somewhat callous-margined : corolla 

 greenish-white or yellowish, about three-fourths inch long, somewhat pubescent, a little 

 constricted at the orifice ; the tube slightly enlarging upward ; the sinuately-lobed limb 

 about 4 lines in diameter. — DC. Prodr. xi. 5(32; Gray, Bot. Calif, i. 545. N. miiltijiora,

 Acad. V. 166, and perhaps of Dunal, 1. c, but the figure in Mocino & Sesse, Ic. Fl. Mex. 

 ined. t. 909, represents a more funnelform corolla. N. (jlandulosa, Buckley in Proc. Acad. 

 Philad. 1862, 166. —Texas to S. E. California. (Mex.) 



N. Palmeri. Yiscid-tomentose throughout, except the corolla : stem apparently 3 feet 

 high, loosely branched above : leaves as of the preceding, but acuminate and mostly with 

 undulate margins, the larger 5 or 6 inches long : flowers sparsely racemose, short-pedicelled : 

 calyx-lobes lanceolate-subulate, somewhat unequal, longer than the tube, half the length 

 of the corolla, conspicuously surpassing the capsule : corolla white tinged with green, an 

 inch long, neither constricted nor dilated at the orifice, externally somewhat pubescent : 

 the conspicuously 5dobed limb 6 or 7 lines in diameter. — Northern Arizona, on Williams 

 Fork, Palmer (no. 433, coll. 1876). 



== = Leaves not clasping : flowers vespertine, and closing before noon or under sunshine. 



N. Clevelandi. Viscid-pubescent, or the stem (a foot or two high) villous : leaves ovate 

 or the upper ovate-lanceolate (2 or 3 inches long) ; the lower obtuse and with margined 

 petiole not dilated at base ; the upper subsessile and gradually narrowing from a broad and 

 rounded or truncate subsessile base into an acuminate apex : bracts lanceolate : flowers 

 paniculate-racemose ; calyx-lobes linear, unequal ; the longer fully twice the length of the 

 tube, more than half the length of the corolla : the latter greenish-white tinged with violet, 

 almost glabrous, an inch long, quite salverform ; the somewhat Sdobed limb half inch in 

 diameter. — California, in dry bed of streams, ChoUas Valley near San Diego, Cleveland, 

 Palmer (no. 267, coll. 1875). Near Santa Barbara, Rotlirock, a smaller-flowered form. 



N. attenuata, Torr. More or less viscid-pubescent, a foot or two high : leaves all on 

 naked and mostly slender petioles and acute or merely obtuse at base ; the lower ovate or 

 oblong (H to 4 inches long) ; the upper from oblong-lanceolate and attenuate-acuminate to 

 linear-lanceolate or linear: inflorescence loosely paniculate and naked above: pedicels 

 short: calyx-teeth triangular-lanceolate or subulate, with thin edges, almost equal, much
