Herbs (or one or two soft-woody plants), nearly all of American origin, heavy- 

 scentetl, viscid- pubescent, narcotic-poisonous, with mostly entire leaves and panicu- 

 late or racemose ilowers, some of them ratlier sliowy. Our species all annuals. 



§ 1. Floivers pink-red {sometimes in. cultivation white), open through the day: capsule 



septicidal, dividing the two placentae as well as the 2)artifion. Tau'acum. 



1. N. Tabacum, Linn. (Common Toiucco.) Tall, large-leaved, with a iianiclo 

 of ahort-pedicelled Ilowers: corolla 2 inches long, funnclform with a wide or inllatod 

 throat, and sjireading acute or acuminate lobes. 



Var undulata, Hendtner. Leaves very long and narrowly lanceolate, nndulato 

 l)olow tiie middle, gradually and much tapering to the slender apex : corolla-lobes 

 also much acuminate. —iV. caudata, Nutt. VI Gamb. 181 1 



The common Tobacco, of Central or South American origin, is merely cultivated in California 

 lh.9 may have been the case also witli Nuttall's N. mudata, from Monterey ; whicUp S to 

 be he same as the Ya^ui Tobacco, found in a cultivated state in Aruona or Sonoraf W ir 

 lalrmr. It is probably the A^ lancifolia, WiUd., and A^. Ybarreiuns, IIBK. 



§ 2. Flowers xuhite, greenish, or yellowish : capsule septifragal, leaving the thin par- 

 tition with the undivided jolacental column in the centre. 

 * Corolla more or less constricted at the orifice, dull-colored, open through the dag; 

 the lobes short and rounded. 



2 N. rustica, Linn, father stout, a foot or two high : leaves petioled, ovate, 

 or the lower somewhat cordate, these oftener a foot long: panicle thyrsiform- calvx 

 broad, and with short and broad teeth, shorter than the globular at first onlv 

 2-vayed capsule : corolla short an.l broad, less than an inch long, hanlly thrice the 

 length of tiie calyx, oblong-inflated from the short narrow base : the broad lobes 

 reticulate-veiny. 



Waste grounds, in California, a^ well as eastward and nortlnvard, probably escaped from 

 aboriginal cultivation : the native country uncertain. ^ ^ escapea Horn 



3 N. trigonophyUa, Dunal. Ii,vther slender, one to three feet high • leaves 

 ssile, oblong, 2 to 4 inches long, or the upper smaller; the lower obovate, with 



narrow tapering auriculato and partly clasping, the upper with broader an.l juore
