 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 from thickish and scaly-toothed rootstocks, nearly 

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

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

 5-7-cleft 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, commonlj' 

 forked : small cymes rather open : divisions of the deeply .S-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 llississippi. 



§ 2. Decemium, Raf. Biennial : calyx appendaged with a reflesed 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. Xov. 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 trimcate or cordate base, palmately 5-7- 

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

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

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

 broadening at base imder the one-seeded fruit. — Fl. i. 134. II. {Decemium) trilohum, Raf. Fl. 

 Ludov. 33. Decemium hirtum, Raf. lied. Fl. ii. 21-3. y^emophila paniculaia, Spreng. Syst.

2. NEMOPHILA, Xutt. (Nt'iiog, a grove, and cpiXiw, I love.) — X. 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. — Xutt. in Jour. Acad. Philad. ii. 179 ; Barton, Fl. Am. Sept. ii. t. 61 ; 

 Gray, I.e. 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 Cahfornian. ) 



•i— Seeds globular, smooth or minutely pruinose, with a very prominent papillEeform caruncle. 

 ""N. maculata, Bentll. 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 Xevada.

-t— -i— Seeds oblong-oval, at maturity usually more or less tuberculate-corrugated or rugose:
