HYDROPHYLLACE.E. (WATERLEAF FAMILY.) 327 



the lowest mostly 2-parted, the uppermost confluent ; peduncles longer than the 

 petioles of the upper leaves, forked ; calyx-lobes narrowly linear, bristly-ciliate. 

 — Damp rich woods, Maine to Virginia and westward. June. — Peduncles 

 forked : clusters rather dense. 



3. H. Caimtletise, L. Nearly smooth (1° high) ; leaves palmatehj 5-7- 

 lobed, rounded, heart-shaped at the base, unequally toothed ; those from the root 

 sometimes with 2-3 small and scattered lateral leaflets; peduncles much shorter 

 than the long petioles, forked, the crowded (nearly white) flowers on very short 

 pedicels; calyx-lobes lincar-awl-shaped, nearly smooth. — Damp rich woods, 

 W. New England to the mountains of Virginia, and northward. June, July. — 

 Eootstocks thickened and very strongly toothed in 2 rows by tiie persistent bases 

 of the stout petioles : leaves 3' -5' broad. 



* * Calyx with a small reflexed appendage in each sinus: stamens sometimes not ex- 

 serted {probably two forms of flowers, as in some Borraginaceas, p. 321, <j-c\). 



4. II. appcmdicsilattain, Michx. (Hairy Watekleaf.) Hairy; 



stem-leaves palmately 5-lobed, rounded, the lobes toothed and pointed, the 

 lowest pinnatcly divided ; cymes rather loosely flowered ; pedicels (at length 

 slender) and calyx bristly-hairy. — Open woods, W. New York to the Alle- 

 tjhanies of Virginia, Wisconsin, and westward. June. 



2. NEMOPIIILA, Nutt. Nemophila. 



Calyx 5-parted, and with a reflexed tooth or appendage in each sinus, more 

 or less enlarged in fruit. Corolla bell-shaped or almost wheel-shaped ; the lobes 

 convolute in the bud ; the tube mostly with 10 small folds or scales inside. Sta- 

 mens included: anthers ovoid or heart-shaped. Placentae (bearing each 2-12 

 ovules), pod, and seeds much as in Hydrophyllum; the embryo larger. — Dif- 

 fuse and fragile annuals, with opposite or partly alternate pinnatifid or lobed 

 leaves, and one-flowered peduncles ; the corolla white, blue, or marked with pur- 

 ple. (Name composed of vepos, a grove, and (piXeat, to love; from the place of 

 growth they affect.) 



1. W. issierocalyx, Fisch. & Meyer. Small, roughish-pubescentj steins 

 diffusely spreading (2' -8' long) ; leaves parted or deeply cleft into 3-5 round- 

 ish or wedge-obovate sparingly cut-lobed divisions, the upper leaves all alter- 

 nate ; peduncles opposite the leaves and shorter than the long petioles ; 

 flowers minute ; corolla white (U" long), longer than the calyx ; placenta; each 

 2-ovuled; pod 1 - 2-seeded. (Ellisia microcalyx, Nutt. Nemophila evanescens, 

 Darby.) — Rich moist woods, Virginia (near Washington), and southward. 

 April - June. 



N. iNsfGNis, N. maculata, &c. are showy Californian species, now com- 

 mon in gardens. 



3. EL.L.ISIA, L. Ellisia. 



Calyx 5-parted, without appendages, enlarged and foliaceous in fruit. Corol- 

 la bell-shaped, not longer than the calyx, 5-lobed above ; the lobes imbricated 

 In the bud, the tube with 5 minute appendages within. Stamens included.
