Nemophila. HYDEOPHYLLACE.E. 503 



2. H. occidentale, Gray. A foot or two high, hirsutely pubescent or above 

 somewhat hispid : leaves elongated-oblong in general outline, parted or below 

 divided into 7 to 15 oblong and mostly incised divisions : peduncles longer than 

 the petioles and generally surpassing the leaves (4 to 'J inches long), bearing one or 

 two rather small and capitate clusters of bluish flowers : calyx very hispid or hispid- 

 ciliate, deeply parted into lanceolate rather obtuse divisions : anthers linear. ■ — Proc. 

 Am. Acad. x. 314. //. capitatum, Torr. Pacif. R. Eep. iv. 125, not of Dougl. 



Var. Watsoni, Gray, 1. c. Commonly lower, sometimes only a span or so high 

 and almost stemless, rather soft-pubescent, especially the lower side of the leaves, 

 which, as well as the calyx, is often pale and whitish or cauescent : cyme rather 

 open. — II. maerophyllum, var. occidentale, Watson, Bot. King Exp. 248, mainly. 



In woods, Duffield's Ranch in the Sierra Nevada (JSigelow), Mendoeino Co. {Kellogg), and in 

 Oregon. Var. Watsoni, Sierra Nevada, Bolauckr, .-laikrson, Mrs. Ames; thence to mountains 

 of Utah, Watson, Parry. The larger and more hirsute form, with corolla 4 lines long and pale 

 or white, and hirsute pubescence, approaches the eastern II. maerophyllum, which is larger and 

 with a different calyx. The var. Watsoni has rather smaller and blue flowers, the calyx less 

 hispid, but variable. 



2. NEMOPHILA, Nutt. 



Calyx 5-parted and with a supplementary reflexed lobe at each sinus, enlarging 

 more or less in fruit. Corolla rotate, or inclined to campanulate, deeply 5-lobed ; 

 the lobes convolute in the bud ; the throat appendaged more or less with 10 internal 

 scales or plaits. Stamens and mostly the style shorter than the corolla : filaments 

 naked : anthers linear or oblong and sagittate. Ovary, capsule, etc., nearly as in 

 Uydrophyllum. Ovules 4 (i. e. a pair on each placenta) or considerably more 

 numerous, ripening from 1 to 16 seeds. — North American annuals, the greater 

 number Californian, germinating in autumn and flowering the following spring ; with 

 tender herbage, diffuse or at length procumbent stems, and pinnately lobed or 

 divided leaves, all more or less hirsute : peduncles terminal or lateral, one-flowered, 

 slender : corolla blue, violet, or rarely nearly white. Most of the species are well 

 known in the gardens as ornamental annuals. 



* Leaves mostly alternate : stems long and weak, beset villi sparse mid stiff reflexed 

 hristles by which the plant is disposed to climb: later flowers unaccompanied by 

 leaves and therefore loosely racemose; ovules only 4. 



1. N. aurita, Lindl. Stems 1 to 3 feet long : leaves all with an auriculate 

 dilatcd and clasping base or winged petiole, ahuve deeply pinnatitid into 5 to '.I 

 oblnng nr laiieeulaie and mostly letroi'se lobes: calyx -appendages small: corolla 

 violet, nearly an inch in diameter, its internal appendages broad, partly live, in 

 pairs at the base of each stamen, seeds globose, reticulated and the spares deeply 

 sunken. — Bot. Peg t. 1601 ; Brit. Fl. (lard. ser. 2, t. 338 ; A. DC. Prodr. be. 290. 



Low shad; grounds, from the Sacramento Valley to San Diego. 



2. N. racemosa, N'nti. Weaker and more slender: leaves shorter, rather ovate 



ii tline, with fewer divisions, and a naked petiole not auricled af base: flowers 



one half smaller, the upper ones decidedly racemose. Gray, Proc. 1. c. 315.

* * Leaves oil opposite, not auricled at base, commonly surpassed by the slender 

 peduncles: ovules 7 /•- 24, ripening about I to 16 set Is; thesi usually with a sort 

 of caruncle.
