 simple up to the paniculate inflorescence: lower leaves ovate or oblong, 

 2-4 inches long ; the upper from oblong-lanceolate and acuminate-attenuate 

 to linear; all on slender petioles: inflorescence loosely paniculate, naked 

 above : pedicels short : calyx-teeth triangular-lanceolate or subulate, with 

 thin edges, almost equal, much shorter than the tube, not over \% lines 

 long and not surpassing the capsule: corolla dull white or greenish, glab- 

 rous, slender-salverform, the tube 1)^-2 inches long, the obscurely 5-lobed 

 or angulate limb 4-6 lines in diameter, opening only at night and usually 

 closing before noon, or under sunshine, filaments slender, equally inserted 

 low down on the tube of the corolla : capsule 2-5 lines long, ovate, acute, 

 2-valved, the valves bifid. Along streams, Brit. Columbia to California 

 and Nevada, east of the Cascade Mountains. 



N. Bigelovii Watson Bot. King 276, t. 27 fig. 3-4. Soft-pubescent 

 and more or less viscid : stem stoutish, erect, i-3 feet high : lower leaves 

 broadly lanceolate, sessile or on short and broad petioles, 5-7 inches long, 

 obtuse or acutish, the upper ones generally reduced upward, lanceolate 

 and more or less attenuate to linear, sessile and with more or less clasping 

 base : inflorescence loose-racemiform, with all the upper flowers bractless : 

 pedicels short and rather stout : calyx- teeth unequal, linear- subulate, about 

 equalling the tube, surpassing the capsule : tube of the corolla 1-2 inches 

 long, narrow, with a gradually expanded throat; the limb 12-18 lines in 

 diameter, 5-lobed, the lobes acute, expanding only at night or in cloudy 

 weather : filaments more or less unequally inserted in the upper part of the 

 tube of the corolla : capsule thin-walled, obtuse, 4-6 lines long, 2-celled, and 

 4-valved at the apex. Dry grounds, Umpqua Valley Oregon to California 

 and Nevada. 



N. qnadrivalvis Pursh Sims Bot. Mag. t. 1778. Viscid-pubescent: 

 stem stout, 1-2 feet high, branching from near the base: leaves oblong or 

 the lowermost ovate-lanceolate and the uppermost lanceolate or linear, 

 acute at both ends, sessile or slender-petioled, 4-6 inches long including 

 the petiole: flowers rather few, on short slender pedicels: calyx-teeth 

 linear, about equalling the 4-celled or rarely 3-celled globular capsule: 

 tube of the corolla barely an inch long, the 5-lobed limb \% inches in di- 

 ameter, its lobes ovate and obtusish, veiny: filaments unequally inserted 

 in the upper part of the tube of the corolla. Along streams, Oregon and 

 Washington. Was cultivated by the Indians, 



Tar. multivalvis Gray Bot. Cal. i, 546. Stouter and with the calyx 

 corolla and stamens 5-8-merous and capsule several-celled, sometimes an
