 var B,gelovn Torr Pac.f. R. Rep. iv. 127. - California, from Shasta Co. to San Diego, and 

 eastward to Nevada and the border of Arizona. • 



Var. WaUacei, a form with corolla smaller (the tube 12 to 16 lines long) and 

 calyx-teeth shorter, but variable, sometimes hardly surpassing the capsule : upper leaves 

 more disposed to have a broad and roundish or subcordate slightly clasping base ■ herbatre 

 &c., more viscid. — Near Los Angeles and San Diego, Wallace, Cleveland. 



^rr,7^,Pj^7- '^"'i, ''^P^"'^ globular, 4-several-ceIled, at first somewhat succulent: the valves at 

 matuiity thin and rather membranous : coiolia with ampler limb and proportionally shorter more 

 funnelform tube. — Po/^rfjc/ia, Don. PolyclicUs, Miers!, po i ouaiij saoiier more 



N. quadrivalvis, Pursh. A foot high, rather stout, more or less viscid-pubescent low- 

 branching : leaves oblong or the uppermost lanceolate, and the lower ovate-lanceolate 

 acute at both ends, mostly sessile (3 to 5 inches long) ; the lowest larger and petioled • 

 flowers few : calyx-teeth much shorter than the tube, about equalling the 4-celled (or 

 sometimes 3-celled?) capsule: tube of the corolla barely an inch long, the 5-lobcd limb an 

 mch and a half or more in diameter ; its lobes ovate and obtusish, veiny. — Sims Bot Mag

 valvis, Miers, 111. i. 164, & ii. 55, 60, fig. 2-14. — Oregon, and cultivated by the'lndians from 

 Oregon to the Missouri : their most prized tobacco-plant. Perhaps a derivative of the 

 preceding species. 



Var. multivalvis, Gray, 1. c. An abnormal form of cultivation (by aborigines), 

 generally stouter, with calyx, corolla (often over 2 inches wide), and stamens 5-8-merous,' 

 anil capsule several-celled, sometimes an inch in diameter. — .V. muUivabis, Lindl. Bot. Reg.' 

 1. 1057. Polydiclis multivalvis, Miers, 1. c. t.60, fig. 1 & 9. — Oregon, probably known only 

 as an escape from aboriginal cultivation. 

 N. NANA, Lindl. Bot. Reg. t. 833, Nierembergia nana, Miers, must be HesperocMron Callfomicus. 



15. PETtJNIA, Juss. {Petun is an aboriginal name of Tobacco.) — Viscid 

 Sotith American herbs, with entire leaves, the upper disposed to become opposite, 

 and scattered flowers becoming lateral : two large-flowered species and their 

 hybrids familiar in gardens ; an inconspicuous small-flowered one is a naturalized 

 weed, and perhaps indigenous along the southern borders of the U. S. It forms a 

 peculiar section, and has received several generic names. 



P. parviflora, Juss. A small prostrate or diffusely spreading annual, much branched, 

 more or less pubescent : leaves oblong-linear or spatulate, rather fleshy, seldom half an 

 inch long, nearly sessile : peduncles very short : calyx-lobes resembling the smaller leaves : 

 corolla purple with a pale or yellowish tube, 4 lines long, funnelforni ; its short refuse lobes 

 slightly unequal: capsule small, ovoid. — Juss. in Ann. Mus. ii. 216, t. 47 ; Miers, 111. i.
