1. Polydiclis multivalvis. Nicotiana multivalvis, Lindl. Bot. Reg. 
tab. 833; Don, Dict. iv. 466 ;—viscido-pilosa, foliis carnosis, 
ovato-lanceolatis, breviter petiolatis, utrimque acuminatis, in- 
tegris, margine undulatis, demum fere glabris ; floribus soli- 
tariis, paucis, axillaribus ; corolla magna, limbo explanato, al- 
bida, venis purpureis picta, 5—6-mera.—Columbia River, in 
locis saxosis. 
This plant is said to be of a strong hircose odour and viscid ; 
the leaves of the specimens I have seen are 6 inches long, 24 
inches broad, on a petiole not longer than 4 or 3 an inch, which, 
together with the midrib, is fleshy, broad, and semiterete. The 
peduncle is scarcely more than { inch long; the calyx about 
5 inch in length, and 3 inch diameter in its broadest part, con- 
tracted above, and divided into five, sometimes six very acute lan- 
ceolate teeth, one-third of its entire length ; it has ten or twelve 
prominent nervures with intermediate reticulations. The tube of 
the corolla is cylindrical, somewhat swollen at the base, 13 mch 
long, 4 inch diameter ; the border is very broad, expanded, ‘about 
2 inches across, and divided to nearly half its breadth into five, 
sometimes six triangular obtuse segments: it is of a whitish 
colour, with anastomosing purplish lines. The stamens are equal 
in number to the segments of the corolla, and the anthers rise 
to the mouth of the tube. The berry is large, globular, 1} inch 
diameter, marked with deep grooves, corresponding with the 
number of cells, which vary from six to twelve ; it is umbilicate 
at the summit, and crowned by the persistent style, its lower 
half being closely invested by the swollen calyx. 
2. Polydichs suateaneanns. Nicotiana quadrivalvis, Pursh, F/. 
Am. Sept. i. 141; Lehm. Hist. Nicot. c. 45. tab. 4; Don, 
Dict... 466 ; Bot. "Mag. tab. 1778 ;—viscido-pilosa, caule her- 
baceo, ramoso ; foliis oblongis, utrinque attenuatis, integris, 
superioribus lanceolatis, subsessilibus ; floribus 5-meris, ovario 
3—4-loculavi, calyce pilosiusculo, corolla genitalibusque glabris, 
stigmate 3—4-lobo.— Missouri. 
The leaves of this species appear somewhat smaller than m the 
foregoing species, and are slightly ciliate on the margin, with 
jointed articulated hairs; the corolla is also much smaller, and 
the globular, usually 4-celled capsule, wholly enclosed in the per- 
sistent calyx, is about half an inch m diameter.
