NICOTIANA 



and does not close in the morning on cloudy days. One 

 of the novelties in 1899 and 1900. 



DDD. Color of corolla rose. 



4. Sanderae, Hort. Sander (N. alata x N. For- 

 getiana). Herbaceous, annual, viscid-pubescent: sts. 

 2-3 ft. tall, of bushy habit: basal Ivs. large spatulate, 

 undulate; st.-lvs. oblong-lanceolate, short-petioled,

 tive and popular garden plant intro. into U. S. in 1904. 



cc. Lobes of corolla obtuse or rounded. 

 D. Lvs. petioled. 



5. acuminata, Hook. (Petunia acuminata, Graham. 

 P. viscosa, Miers. N. diversifolia, Nees?) Herbaceous, 

 annual, viscid-pubescent: st. slender, branching: Ivs. 

 ovate-lanceolate, undulate, sometimes subcordate, nar- 

 rowed into a short petiole, apex long-acuminate: fls. 

 loose-racemose; calyx glandular-pubescent, membrana- 

 ceous-scarious, 5 nerves ending in narrow, linear, 

 unequal teeth; corolla white, about 3 in. long; tube 

 green-veined, slightly curved, swollen above, nearly 5 

 times as long as the calyx; limb 5-parted; lobes small, 

 obtuse, emarginate expanded, green- veined without: 

 caps, nearly equaling the calyx. Chile. B.M. 2919. 

 Not common in cult., under which it appears to be 

 annual, but in its native habitat it is perennial. 



DD. Lvs. sessile. 

 E. Fls. rose-colored. 



6. Forgetiana, Hort. Sander. Herbaceous, annual: 

 st. 2-3 ft. high, branching from the base: Ivs. papery, 

 soft, pubescent; basal Ivs. oblong-lanceolate, largest 

 about a foot long, obtuse, tapering to a winged petiole, 

 slightly undulate; st.-lvs. similar, but smaller, ovate, 

 with decurrent blades: fls. in broad loosely branched 

 panicles; branches slender, glandular-pubescent; lower 

 bracts leafy, narrow, acute, becoming smaller upward ; 

 pedicels slender, shorter than the fls.; calyx small, 

 5-toothed, covered with stiff hairs; teeth unequal, very 

 slender, rigid; corolla narrow, funnelform, 1-1 J4 in. 

 long, 1 in. diam.; sparsely hairy; lobes of the limb 

 nearly equal, triangular, obtuse; stamens included; 

 filaments hairy at base, jointed above their attach- 

 ment to the corolla; ovary glabrous. Brazil. B.M. 

 8006. Intro, into cult, about 1901 but not much in 

 the trade, being used mostly in hybridizing. 



EE. Fls. greenish. 

 F. St. pubescent throughout. 



7. noctiflfira, Hook. (N. longiflbra noctifibra, Voss). 

 Herbaceous, perennial, glandular -viscid, hairs ap- 



Eressed: st. 2-3 ft. tall, slender, branching: Ivs. petio- 

 ite, oblong-lanceolate, sinuate or undulate-plicate, the 

 lower oblong-obtuse, the upper nearly sessile, linear- 

 lanceolate, acute: fls. pedicellate, horizontal, in terminal 

 panicles; calyx tubular, with 5 unequal, narrow, lanceo- 

 late, acute teeth; corolla salverform, night-opening, 

 fragrant, greenish purple without, white within, 3-4 

 times longer than the calyx; tube cylindric; lobes equal 

 obcordate, emarginate, oblong; nectar-ring orange, 

 thickened: caps, longer than the calyx. Argentina and 

 Chile. B.M. 2785. Var. albifldra, Comes, has the 

 fls. nearly glabrous, glaucous, and greenish white or 

 sometimes pure white without instead of purplish, or 

 sometimes with a purplish vein in each corolla-lobe. 

 Argentina. Very decorative. Intro, into U. S. from 

 Italy in 1908. 



FF. St. glabrous above. 



8. suaveolens, Lehm. Herbaceous, annual or bien- 

 nial, usually viscid: st. 1-2 ft. tall, densely villous at 

 base, glabrous above: Ivs. at base subpetiolate, spatu- 

 late, obtuse, above ovate-lanceolate, acute, undulate, 

 petiole decurrent, the uppermost nearly sessile or 

 clasping, acuminate, villous: fls. pedicellate, nodding, 

 distant, bracteolate, in terminal racemes; calyx 5- 

 toothed, striate, tubular, pubescent; teeth linear- 

 lanceolate, narrow, acuminate, unequal; corolla green- 

 ish purple, night-opening, fragrant, pubescent, salver- 

 form; tube slender, cylindric, striate, 4 times longer

than the calyx; limb purplish without, white within; 

 somewhat 2-lipped, the upper lobes very small, all 

 subrotund, obtuse or emarginate: caps, ovate, obtuse, 

 nearly equaling the calyx. Austral. It is said to grow 

 in moderate shade. Var. undulate, Comes (N. undulata, 

 Vent., not Ruiz & Pav.). The plant is taller: Ivs. large, 

 undulate: fls. larger. B.M. 673. Var. macrantha, Comes 

 (N. frdgrans, Bern.). The st. is glabrous: Ivs. oblique, 

 subcordate-ovate, sinuate-repand, acute: corolla large, 

 white, mouth expanded; lobes obtuse. B.M. 4865. 



BB. Ovary 4- to many-celled. 



9. quadrivalvis, Pursh. Herbaceous, annual, viscid- 

 pubescent: st. erect, or branching: Ivs. 4-6 in. long, 

 E etiolate, oblong, the upper nearly sessile, entire, lanceo- 

 ite, acute; margin often somewhat revolute: fls. few on 

 short slender pedicels; calyx -teeth linear, corolla 

 tubular, swollen below, tube about 1 in. long; limb 1% 

 in. diam.; lobes ovate, obtuse, dark purplish without, 

 white within: caps. 4-celled, subglobose, nearly equal- 

 ing the calyx. Formerly cult, by the Indians and still 

 grown by them to a slight extent; probably does not 

 occur outside Indian cult, and gardens; possibly only a 

 cult, mutant of N. Bigelovii, as it appeared in Setchell's 

 pedigree cultures of that species. Fresh Ivs. said to 

 smell like a goat, but the odor disappears on drying. 

 N. multivalvis, Lindl., known only from Indian cult, 

 in Ore. and Wyo., differs in the many-celled indehis- 

 cent caps., and many-lobed corolla-limb.
