HYDROPHYLLACE^E. (WATERLEAF FAMILY.) 327 



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

 pefc'ofes 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. II. CaimdeilSC, L. Nearly smooth (lhigh); leaves palmately 5-7- 

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

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

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

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

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

 Rootstocks thickened and very strongly toothed in 2 rows by the persistent bases 

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



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

 sertcd (probably two forms of flowers, as in some Borraginacece, p. 321, frc.). 



4. II. appendicillfatlim, Michx. (HAIRY WATERLEAF.) Hairy; 

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

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

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

 ghanies 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 ve/ios, a grove, and $iXeo>, to love; from the place of 

 growth they affect.) 



1. N. microcalyx, Eisch. & Meyer. Small, roughish-pubescent ; stems 

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

 ish or wcdge-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 (l" long), longer than the calyx ; placenta} each 

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

 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. ELLISIA, L. ELLISIA. 



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

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

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