438 SUPPLEMENT. 



13. OESTRUM, L. 



« 



C. Parqui, L'Her., of Chili and Buenos Ayres, cultivated in many warm countries, appears 

 to have become spontaneous at San Antonio, Texas, coll. Dr. Ball, Palmer. Palmer's plant is 

 G. multinervium, Watson, Proc. Am. Acad. xvii. 128 : so probably is that of Dunal. 



14. NICOTIANA, Tourn. Append to genus, on p. 243: — 



N. Glau'ca, Graham. Arborescent, soft-woody below, glaucous and glabrous : leaves long- 

 petioled, ovate and subcordate, entire or repand : flowers loosely paniculate : corolla greenish 

 becoming yellow, inch or two long, tubular, contracted at throat, and with erect 5-crenate 

 limb not longer than the orifice. — Bot. Mag. t. 2837. — Native of Buenos Ayres, not rare in 

 cultivation, rather widely naturalized in S. California and S. Texas. 



SCROPHULAEIACE^]. 



Digitalis purpurea, L., the Foxglove, the type of the tribe Digitahae, p. 248, is locally 

 naturalized in British Columbia, on the Pacific coast. 



4. ANTIRRHINUM, Tourn. 



A. virga, Gray, p. 252, is a perennial, the larger plants branched from the base and becom- 

 ing 6 or 7 feet high : corolla purple. Recently collected in Lake Co., Cleveland, Rattan. 



The Californian species (of 4— m— ), which are prehensile by lateral shoots acting as tendrils, 

 now augmented, may be defined as follows : — 



A. Cotllterianum, Benth., p. 252. Marked by its truly spicate inflorescence, and com- 

 paratively large corolla, with very protuberant palate greatly exceeding the short upper lip. 



A . Orcuttianum, Gray. Nearest the preceding, more slender, smaller-flowered, glabrous 

 up to the loosely spicate inflorescence, which is more disposed to bear tortile branchlets : 

 corolla about 4 lines long ; lower lip not much larger than the upper : leaves linear or lower- 

 most spatulate-lanceolate : seeds tuberculate-favose. — Bot. Gazette, ix. 53. — Near San 

 Diego and adjacent Lower California, Orcutt. 



A . Nevinianum, Gray, 1. c. Much resembles the foregoing : seeds longitudinally cris- 

 tate-costate, as in A. Nuttallianum. — Los Angeles Co., at San Juan Capistrano, Nevin, 

 and near San Diego, Orcutt. 



A. Nuttallianum, Benth., p. 253. Well marked by the scattered slender-pedicelled flow- 

 ers (with short comparatively equal-lipped corolla not over 4 lines long), all subtended 

 by ovate leaves or leaf-like bracts, and principal leaves distinctly petiolate : seeds acutely 

 cristate-costate. Extends well into Arizona, &c. 



A. subsessile, Gray. Erect and less diffuse than the foregoing, which it most resembles, 

 extremely glandular-viscid : flowers more racemose, longer than the pedicels or even sub- 

 sessile ; lower lip of corolla large in proportion : leaves ovate, all sessile or nearly so : seeds 

 of the preceding. — Bot. Gazette, ix. 53- — San Diego, &c, Cleveland, Orcutt, and Santa 

 Catalina Island, Schumacher. 



A. subcordatum, Gray. Of the group with flowers sessile or subsessile in the axils of 

 sessile leaves, and very unequal calyx, to which belong A. vac/ans and A. Breweri: rather 

 large and stout, pubescent or below hirsute : lower leaves unknown ; upper closely sessile, 

 ovate, subcordate, thickish : flowers half-inch long : upper sepal large and oval, longer than 

 the rest, which are linear-lanceolate : corolla half-inch long, with ample throat and almort 

 equal lips, ochroleucous : longer filaments dilated at apex : seeds favose and the edges 

 of the pits muriculate. — Proc. Am. Acad. xx. 306. — Stony Creek, Colusa Co., California, 

 Rattan.
