3G8 HYDROPHYLLACE.E. (WATERLEAF FAMILY.) 



3. H. Canadense, L. Nearly smooth (1° high); leaves palmalely 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 linear-awl-shaped, nearly smooth. — Damp rich woods, W. 

 New England to the mountains ofVirginia and northward. June -Aug. — 

 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 

 exserted (probably two forms of flowers, as in some Borraginacea, $"c). 



4. H. appendiculatum, Michx. 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, New York to Virginia, Wisconsin, and westward. June, July. 



2. NEMO PHI LA, 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. Placenta; (bearing each 2-12 

 ovules), pod, and seeds as in Hydrophyllum. — Diffuse and fragile annuals, with 

 opposite or partly alternate pinnatifid or lobed leaves, and one-flowered pedun- 

 cles ; the corolla white, blue, or marked with purple. (Name composed of vtpos, 

 a grove, and (pi\e<o, to love.) Some handsome species are garden annuals. 



1. N. micrdcalyx, Fisch. & Meyer. Small, roughish-pubescent ; stems 

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

 or wedge-obovate sparingly cut-lobed divisions, the upper leaves all alternate; 

 peduncles opposite the leaves, shorter than the long petioles ; flowers minute ; 

 corolla white, longer than the calyx ; placentas each 2-ovuled ; pod 1 -2-seeded. 

 (Ellisia microcalyx, Nutt. Nemophila evanescens, Darby.) — Moist woods, 

 Virginia (near Washington), and southward. April -June. 



3. ELLISIA, L. Ellisia. 



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

 bell-shaped or cvlindraceous, not longer than the calyx, 5-lobed above ; the lobes 

 imbricated or convolute in the bud, the tube with 5 minute appendages within. 

 Stamens included. Placenta; (each 2-ovuled), fruit, and seeds much as in Hy- 

 drophyllum. — Delicate and branching annuals, with lobed or divided leaves, 

 the lower opposite, and small whitish flowers. (Named for John Ellis, a dis- 

 tinguished naturalist, an English correspondent of Linnaeus.) 



1. E. Nyct61ea, L. Minutely or sparingly roughish-hairy, divergently 

 branched (6'- 12' high) ; leaves pinnately parted into 7-13 lanceolate or linear- 

 oblong sparingly cut-toothed divisions ; peduncles solitary in the forks or oppo- 

 site the leaves, 1 -flowered ; calyx-lobes triangular-ovate lanceolate, pointed, about 

 the length of the cylindraceous (whitish) corolla (in fruit becoming nearly £' 

 long) ; pod pendulous. — Shady damp places, W. New Jersey and E. Pennsyl- 

 vania to Virginia. May -July.
