NemopMa. HYDROPHYLLACE^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 9 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. H. capitatum, Torr. Pacif. E. 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 canescent : cyme rather 

 open. N. macrophyllum, var. occidentale, Watson, Bot. King Exp. 248, mainly. 



In woods, Duffield's Ranch in the Sierra Nevada (Bigelow), Mendocino Co. (Kellogg), and in 

 Oregon. Var. Watsoni, Sierra Nevada, Bolander, Anderson, 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 H. macrophyllum, 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, &c., nearly as in 

 Hydrophyllum. 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 with sparse and stiff reflexed 

 bristles 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- 

 dilated and clasping base or winged petiole, above deeply pinnatifid into 5 to 9 

 oblong or lanceolate and mostly retrorse lobes : calyx appendages small : corolla 

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

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

 sunken. Bot. Eeg t. 1601 ; Brit. Fl. Gard. ser. 2, t. 338 ; A. DC. Prodr. ix. 290. 



Low shady grounds, from the Sacramento Valley to San Diego. 



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

 in outline, with fewer divisions, and a naked petiole not auricled at base : flowers 

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



San Diego, Nuttall. Catalina Island, Doll & Baker. 



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

 peduncles: ovules 7 to 24, ripening about 4 to 16 seeds ; these usually ivith a sort 

 of caruncle. 



3. N. maculata, Benth. Leaves lyrately pinnatifid into 5 to 9 short lobes, or 

 the uppermost only 3-lobed : corolla white with a strong violet blotch at the top of
