family). — Dwarf stemless perennials, or possibly biennials (W. N. American), 

 soft-pubescent ; with entire spatulate or oblong leaves, on mostly elongated mar- 

 gined petioles, crowning the caudex or rootstock ; and from their axils sending 

 forth naked one-flowered peduncles, equalling or shorter than the leaves. Parts 

 of the flower occasionally in sixes or sevens. Corolla purplish or nearly white ; 

 the tube and the base of the subulate filaments more or less hairy or hirsute ; the 

 lobes often slightly unequal. Disk none. Base of the calyx obscurely adnate to 

 the broad base of the conical-ovate ovary, which tapers into the rather stout style : 

 stigmas minute. Ovary 1-celled ; the narrow placentae projecting more or less on 

 incomplete half-dissepiments : ovules 20 or more to each placenta. Capsule 

 loculicidal, 15-20-seeded. Seeds pretty large, with a somewhat fleshy minutely 

 reticulated testa. — A genus of doubtful affinity, but most probably Hydrophyl- 

 laceous. — Watson, Bot. King, 281 ; Gray, Proc. Am. Acad. x. 330, & Bot. Calif,

H. Californicus, "Watson. Leaves copious in a rosulate radical tuft : corolla some- 

 what oblong-oampanulate ; the lobes shorter than the tube. — Bot. King, 281, t. 30. Ourisia

 ward to Washington Terr., and east to the mountains of Utah. — Leaves an inch or two 

 long, besides the petiole, into which the blade abruptly contracts or gradually tapers. 

 Corolla from nearly half to three-fourths of an inch long in the largest specimens; the 

 lobes oblong. Here belongs Nicotiana nana, Lindl. Bot. Reg. t. 833.

L. Californica, Gray, 1. c. Small and depressed winter-annual, canescently pubescent, 

 and the calyx white-villous : stem branched from the base, divergently and repeatedly 

 dichotomous : leaves alternate, rosulate at base, and crowded at the summit of the branches ; 

 entire, spatulate and tapering into a short petiole, nearly veinless, 3 to 5 lines long : flow- 

 ers sessile, solitary in the lower forks, cymose-glomerate at the leafy extremity of the 

 branches : sepals very narrowly linear, not widening upward, in fruit 2 lines long and 

 exceeding the short-oval retuse capsule : corolla apparently white, a line long, not surpass- 

 ing the calyx, moderately 5-lobed : styles shorter or not longer than the ovary : placentae or 

 half-dissepiments narrow, adhering to the valves : seeds half a line long, somewliat rugose- 

 foveolate in the manner of Conanthus. — Desert region of San Bernardino Co., California,

 woody-based (N. & S. American and one Hawaian), of various habit; the corolla 

 purple, bluish, or white ; the stamens sometimes equally, oftener unequally adnate 

 to the base or lower part of the tube. (Besides the following there are several
