2 H OCCidentale, Ovay. A foot or two hit^li, liirsutely pubescent or above 

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

 divided into 7 to 15 oblong and mostly incised divisions : pe.luncles longer than 

 the petioles and generaUy surpassing the leaves (4 to 9 inch(!s long) bearing one or 

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

 ciliate deoDlv parted into lanceolate rather obtuse divisions : anthers linear. — i roc.

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 — //. marroph^/llum, var. occidentale, Watson, Bot. King Lxp. 24b, mainly.

2. NEMOPHILA, Nutt. 



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

 more or less in fruit. CoroUa 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, aU more or less hirsute : peduncles terminal or lateral, one-flowered, 

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

 known in the gardens as ornamental annuals. 



* Leaves mostl!/ alternate : stems long and iveal; beset with sparse and stiff reflexed 

 bristles by luliich 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 pmnatihd into o to J 

 oblon- or lanceolate and mostly retrorse lobes: calyx appendages smal : corolla 

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

 pairs kt the base of each stamen . seeds globose, reticulated and the spaces_ deeply 

 sunken. -Bot. Eeg t. 1601; Brit. Fh 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. dlo. 



San Diego, NiMall. Catalina Island, Ball k Baker. 

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



peduncles: ovides 7 to 24, ripemng about 4 ^o 16 seeds; these usually with a sort 



of caruncle. 



3. N. maculata, Benth. Leaves lyrately pinnatifid into 5 to 9 s^o/t lobes, or 

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