54G SCUUriiULAlllACE.E. XicoUuua. 



Dry plains aiul liills, Monterey Co. to the Moliavo, iiud along the eastern borders of the State 

 in Nevada ; eabt to Colorado. 



5. N. Bigelovii, W'alsun. J.uiger iiml stouter than the pieceiliiig : leuves i)h- 

 long ov ubluiig laiiLuuliitu (1 to G iuclics long, or tlio uppermost siiialler), ouly tho 

 lower ones i)etiole(.l; some ol" tho upper often with broailer anil partly clasping base: 

 liower.s scattered : teeth of the calyx linear-lanceolate and surpassing the ovate 

 •i-valved capsule : corolla nearly salverforni, with tube an inch and a half long, and 

 a 5-cleft border of an inch or more in tliameter, its lobes triangular and acute. —

 Itep. iv. 27. 



Not unconunoii, I'roni bake Co. to San Diego, and east to the borders of Nevada. Very visi^id 

 and stinking : this and the preceding much used by the Indians. 



N. QUAnitiVALVis, I'nrsh, and its variety multivalvis (A", multivalvis, Lindl. Bot. Reg. 

 t. 1057), may be expected in tho northern part of tho State, being not luieommon in Oregon. 

 It may bo distinguisiied from A. Bujelovii by its lower and stouter habit, corolla with proportion- 

 ally shorter tube, broader obtusely 5 - 7-lobetl border, and globose at length thin-walled capsule 

 of four cells, in the var. inuUiculvis of several cells; — an anomaly in the genus. No certain 

 indigenous habitat is known : the plant was cultivated by the aliorigines from the ]\lissouri Kiver 

 to the I'ucilic, and greatly jfrizcil lor its tobacco. A'. JJiijcluvii is perhaps the origiinil of it. 



10. PETUNIA, .luss. 



Calyx 5-parted, persistent; the ilivisions luirrow and I'oliaceous. Corolla funnel- 

 form or somewhat salverform ; the 5-lobed limb plaited in the bud. IStamens 

 unequal, included : filaments and tip of the style more or less incurved. Stigma 

 dilated-capitate and 2-lobed. Capsule simply 2-valved (the valves entire), leaving 

 the placenta in the axis. Seeds numerous, small, scrobiculate. Embryo straightish. 

 — Viscid-pubescent herbs, with entire leaves and lateral or at lirst terminal llowers. 



The oommon Petunias of the gardens are mixtures of two showy species from Buenos Ayies. 

 Very ditlercnt in appearance is the following. 



1. P. parviflora, -I uss. A snudl and iusignilicant annual, nmch branched, spread- 

 ing or nearly pn^strate, pubescent : leaves narrow-spatulate, hardly half an inch 

 long, almost sessile : Howers small (about a third of an inch long), very short- 

 peduncled: calyx-lobes resembling the leaves: corolla purple with a yellowish tube, 

 its short retuse lobes slightly uncujual : capsule ovoid. — Ann. ]\lus. I'ar. ii. 21(), 

 t. 47. Sutpii/iosiiis proslralu, Hook. & Arn. JJot. IJeechey, 123, 370. 



Common on the aca-shorc from the IJay of Monterey soutii : also in Texas, and S. America. 



Order LXVIII. SCROPHULARIACE^. 



Known by the irregular (more or less bilabiate) corolla with lobes imbricated in 

 the bud, didynamous or diandrous stamens, single style, 2-celled many - few-seedetl 

 capsule with the placentui in the axis, ami seeds with a small embryo in cojiious 

 albumen. The oxcei)tions do not concern tho Californian llora, except an intro- 

 duced Mullein, which has 5 perfect stamens. — l''lowers peri'ect. Calyx oi 5 or 

 sometimes 4 distinct or variously united sepals, ('orolia 4 - 5-lobed or i:lcrt, com- 

 moidy bilabiate (ij, i. e. two lobes funning the ujjper and three the lower lip), im- 

 bricated in the l)ud, not plaited. .Stamens borne on the tube of the ci)rolhi, 4 and 

 tlidynamous or only 2, tlij lifth and upper stamen and sometimes the two lateral 

 or anterior ones either alisent or reduced to sterile fdaments or vestiges, rarely (in 

 Vcr/uisrinii, iV'c.) all live present and fertile. Stigma entire, or with two (upjH-r and
