NemopMla. HYDROrHYLLACE.E. 155 



at length open : calyx 5-parted to the very base into narrow linear and spreading liispid- 

 ciliate divisions : corolla nearly white or sometimes deep violet, about a fourth of an inch 

 long. — Lam. 111. t. 97 ; Schkuhr, Handb. t. 35 ; Bot. Reg. t. 331. — Rich woods, Canada 

 to the mountains of Carolina and through the western States northward to Washington 

 Terr, and Alaska (violet-flowered form). — Fleshy rootstock strongly toothed by the per- 

 sistent bases of former radical petioles. 



* * Leaves palmately 5-7-lobed: calyx often bearing minute teeth in the sinuses. 

 H. Canadense, L. A foot or less high frorathickish and scaly-toothed rootstocks, nearly 

 glabrous or very slightly and sparsely hirsute even on the calyx : stems simple and naked 

 below, 1-2-leaved at the summit: leaves bright green, rounded and with a cordate base, 

 5-7-clef t to near the middle ; the larger ones 5 to 7 inches wide ; the radical ones on stout 

 petioles as long as the stem, not rarely furnished with several small and distant pinnately 

 arranged lateral divisions : peduncles mostly shorter than the cauline petioles, commonly 

 forked : small cymes rather open : divisions of the deeply 5-parted calyx narrowly lan- 

 ceolate-linear : corolla open-campanulate, mostly greenish-white : filaments very villous. — 

 Lam. 111. t. 97; Bot. Reg. t. 242. — Damp woods, Canada to the mountains of Carolina, 

 and west to the Mississippi. 



§ 2. Dec^mium, Raf. Biennial : calyx appendaged with a reflexed lobe at 

 each sinus, and somewhat accrescent under the fruit (in the manner of Nemophila^ 

 to which genus this approaches) : stamens little longer than the open-campanulate 

 corolla. — Viticella, Mitch. Nov. Gen. 62. 



H. appendiculatum, Michx. A foot or so high, loosely branching, hirsute with long 

 spreading hairs, and above minutely somewhat viscid-pubescent : radical leaves pinnately 

 5-7-parted or divided; cauline rounded, with truncate or cordate base, palmately &-7- 

 angulate-lobed or the lower deeper cleft, somewhat dentate ; the lobes very acuminate : 

 peduncles exceeding the ujiper leaves : cymes loosely paniculate : pedicels filiform, equal- 

 ling or longer than the calyx ; the divisions of the latter lanceolate-subulate, spreading, 

 broadening at base under the one-seeded fruit. — Fl. i. 134. H. (Decemium) trilobum, Raf. Fl. 

 Ludov. 33. Decemium hirtum, Raf. Med. Fl. ii. 215. Nemophila paniculata, Spreng. Syst. 

 i. 569 ; Beck, Bot. 256. — Damp woodlands, Upper Canada to mountains of Carolina, and 

 west to Missouri and Wisconsin. 



2. NEMOPHILA, Nutt. (Ns'fiog, a grove, and cpdam, I love.) — N. Amer- 

 ican annuals, in California chiefly winter-annuals, diffuse, more or less hirsute, of 

 tender texture ; with opposite or alternate and usually pinnatifid leaves, one- 

 flowered terminal or lateral peduncles, in one or two species inclined to be race- 

 mose, and white, blue, or violet corolla, which in one species only is shorter than 

 the calyx. — Nutt. in Jour. Acad. Philad. ii. 179 ; Barton, Fl. Am. Sept. ii. t. 61 ; 

 Gray, 1. c. 314, & Bot. Calif, i. 503. (The larger-flowered species are common 

 ornamental annuals in gardens.) 



* Ovules 8 to 24, maturing 5 to 15 seeds : leaves all or almost all opposite, surpassed by the slender 



peduncle. (All Californian.) 

 ^— Seeds globular, smooth or minutely pruinose, with a very prominent papillseform caruncle. 

 N. maculata, Benth. Leaves lyrately pinnatifid into 5 to 9 short lobes, or the upper- 

 most somewhat cuneate and 3-lobed : corolla white, with a deep violet blotch at the apex 

 of each of the broad lobes; its very broad scales partly free, hirsute-ciliate with long 

 sparse bristles. — Lindl. in Jour. Hort. Soc. iii. 319, & fig.; PI. Hartw. 326; Paxt. Mag. 

 xvi. t. 6 ; Fl. Serres,.v. t. 431. — California, valley of the Sacramento to the Sierra Nevada. 

 Corolla varying from 9 to 20 lines in diameter. 

 +- -h- Seeds oblong-oval, at maturity usually more or less tuberculate-corrugated or rugosp: 



caruncle more deciduous. 

 N. insignis, Dougl. Leaves pinnately parted into 7 to 9 oblong and often 2-3-lobed 

 divisions : corolla bright clear blue ; the scales within its base short and roundish, partly 

 free, hirsute with short hairs. — Benth. I.e. 275, & Trans. Hort. Soc. i. 479; Bot. Reg.
