156 HYDROPHYLLACE^:.. Nemophila. 



t. 1713; Bot. Mag. t. 3485. N. Menziesii, var., Hook. & Arn. Bot. Beech. 372. Common 

 nearly throughout California, flowering, like the other species, from early spring onward. 

 Corolla from an inch or more down to little over half an inch in diameter. 

 N. Menziesii, Hook. & Arn. Mostly smaller than the preceding : leaves pinnatifid 

 into 3 to 9 lobes : rotate corolla from light blue to white, and commonly with dark dots or 

 spots, especially towards the centre, or sometimes with a dark eye ; the scales at its base 

 narrow, wholly adherent, their free edge densely hirsute-ciliate : appendages to the calyx 

 usually small. Bot. Beech. 152, & 372, first form ; Gray, 1. c. N. linfflora, Fisch. & Meyer, 

 Sert. Petrop. fol. & t. 8, a large blue-flowered form, the corolla an inch wide. N.pedun- 

 culata, Benth. 1. c. ; Torr. Bot. Mex. Bound. 142 (as to char. & pi. coll. Coulter), a small- 

 flowered form. N. utontdfia, Fisch. & Meyer, Ind. Petrop. 1835, & Sert. Petrop. 1. c. ; Bot. 

 Reg. t. 1940; Bot. Mag. t. 3774. N. discoididis, Hortul. ; Fl. Serres, ii. t. 75, a cult, form, 

 with the dark spots confluent into a uniform dark brown-purple eye, or almost covering the 

 corolla (Regel, Gartenfl. 1364, t, 442). Common in California, extending to Oregon. Co- 

 rolla from half an inch to at most an inch in diameter ; the larger forms many-ovulate and 

 much resembling N. insiynis ; the smaller passing towards N. parviflora, and sometimes only 

 7-9-ovulate. 



* * Ovules only 4, i. e a pair to each placenta: loaves all or mainly alternate : flowers mostly 

 large : internal scales of the corolla very broad and partly free, conniving or united in pairs at 

 the base of the filaments: seeds globose, with inconspicuous caruncle or none: peduncles rarely 

 exceeding the leaves, or the later ones forming as it were a naked few-flowered corymb or 

 raceme. 



N. phacelioid.es, Nutt. Sparsely hirsute, a foot or two high : leaves all but the 

 earliest alternate, with naked petioles, 5-9-parted ; the divisions oblong or oval, the larger 

 ones 2-5-lobed : appendages of the calyx oblong or ovate, almost half the length of the 

 lobes: corolla ample, blue; the appendages in throat hairy outside : seeds obscurely im- 

 pressed-punctate. Nutt. in Jour. Acad. Pliilad. ii. 179, & Trans. Am. Phil. Soc. n. scr. 

 v. 192 ; Bart. Fl. Am. Sept. ii. t. 01 ; Bot. Mag. t. 2373 ; Bot. Reg. t. 740 ; Brit. Fl. Card. 

 t. 32. N. Nutlallii, Colla, Ilort. Rip. App. i. t. 5. N. hlrsnta & N. pilosn, Buckley in Proc. 

 Acad. Philad. Low grounds, Arkansas and Texas. Corolla an inch or more in diameter, 

 with white or pale centre. 



N. aurita, Lindl. Hirsute, and the weak stems usually retrorsely hispid, a foot or two 

 long: leaves all with dilated clasping base or winged petiole; the lowest opposite, deeply 

 pinnatifid; the 5 to 9 oblong or lanceolate divisions more or less retrorse : appendages of 

 the calyx small: corolla violet, from two-thirds to nearly an inch in diameter; its internal 

 scales with ero.se and somewhat ciliatc margins: seeds favose-reticulated. Bot. Reg. t. 

 1601 ; Brit. Fl. Gard. n. ser. t. 338. California, from the Sacramento Valley to San Diego. 

 Upper peduncles almost always bractless and at length racemose. 



N. racemosa, Nutt. More slender and weak than the preceding: leaves shorter and 

 with fewer divisions and a naked petiole destitute of auricled base : flowers only half the 

 size, the upper ones racemose. Gray, Proc. I.e. & Bot. Calif. 1. c. San Diego, Nuttull ; 

 Island of Catallna, Dull and Baker. Leaves of ovate rather than linear outline. Corolla 

 little longer than the calyx, only 4 or 5 lines wide. 



# * * Ovules only 4, i. p. a pair to each placenta: lower leaves opposite, and the upper commonly 

 alternate: flowers small or minute: corolla more campaiiulate; its internal scales delicate and 

 nearly glabrous, or obsolete: seeds oval or globose, the caruncle at length evanescent: peduncles 

 shorter than the leaves: plants small or slender, diffuse or prostrate, hirsute-pubescent. 



i Corolla, as in all preceding species, longer than the calyx. 



N. parviflora, Dougl. Leaves pinnately 3-9-parted or cleft, or below divided ; the 

 divisions obovate or oblong; the distinct lower ones either sessile or petiolulate, the upper 

 confluent : appendages of the calyx rather conspicuous : corolla light blue or whitish, 3 to 

 5 lines in diameter; its lobes considerably longer than the tube; its oblong append- 

 ages manifest, wholly adherent by one edge : anthers oblong-sagittate : filaments filiform, 

 inserted on the very base of the corolla. Benth. 1. c. 275 ; Gray, 1. c. N. parviflora & N. 

 pedtinciil(tt:i,U(tn\i.V\. ii. 79. N. heterophytta, TFisch. & Meyer, I.e.; a larger-flowered form. 



- Shady places, British Columbia to California ; common, and exceedingly variable in the 

 foliage, size of corolla, c. Seeds from one to four, smooth and even, with obscure im- 

 pressed punctures or pits, or becoming rather deeply pitted or scrobiculate. All but the 

 upper leaves mostly opposite.
