Nemophila. HYDROPHYLLACE^. 503 



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

 somewhat hisjjid : 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 hispiil or hispid- 



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

Var. WatSOni, Gray, 1. c. Commonly lower, sometimes only a span or°80 high 

 and almost stcmiesa, rather soft-pubescont, especially the lower side of tho loaves, 

 whi(!li, as well as tho calyx, is often palo and whitish or canoscont : cymo rather 

 open. — //. macrophyllum, vur. occidtntale, Watson, Bot. JCing Exp. 248, mainly. 



In woods, DufTield's Ranch in tlie SieiTa Nevada {Bujdow), Mendocino Co. {Kdlogij), and in 

 Ore";on. Var. IFatsoni, Sierra Nevada, Bolander, Anderson, Mrs. Ames; thence to mountains 

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

 or white, and liirsutn pubescence, approaches the eastern H. macrophyllum, which is larger and 

 with a diircrent 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 : fdaments 

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

 Iltjdrophyllum. Ovules 4 (i. o. a pair on each placenta) or considerably more 

 numerous, ripening from 1 to IG seeds. — North American annuals, tho greater 

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

 tender herbage, diffuse ^r at length procumbent stems, and pinnatcly lobcd or 

 divided loave.s, all more or less hirsute : peduncles terminal or lateral, one-flowered, 

 slender : corolla blue, violet, or rarely nearly white. IMost of tho species are well 

 known in the gardens as ornamental annuals. 



* Leaves mostly alternate : stems lorn; and weak, beset with, sparse and stiff reflexed 

 bristles by which the j^lant is disposed to climb ; later flowers unaccompanied by 

 leaves and therefore loosely racemose, ovules only 4. 



,.}• ^' aurita, Lindl. Stems 1 to 3 feet long : leaves all with an auriculate- 

 dilated and clasping base or winged petiole, above deeply pinnatifld 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. Reg t. 1601 ; Brit. FI. Card. 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 out ine, with fewer divisions, and a naked petiole not auricled at base : flowers 

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



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



* * Leaves all opposite, not auricled at base, common!// surpassed by (he slender 

 peduncles : ovules 7 to 24, rlprniny about 4 to 1(1 seals; these usually with a sort 

 of caruncle. 



3. N. maculata, Bonth. Loaves lyratoly pinnatind into 5 to 9 short lobos, or 

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