92 HYDROPHYLLACEiE. HTDRoPHYLLrM. 



4-6 inches long. Peduncles 3-5 inches long, usually forked ; each division bearing a 

 dense cymose cluster of racemes : pedicels 3-6 lines long. Calyx deeply 5-parted ; the 

 segments linear, hispidly fringed with long spreading white hairs. Corolla white, with purplish 

 veins ; the lobes ovate, obtuse : on the inside of each, and extending about half its length, is 

 a linear process or scale, with a longitudinal closed chink. Stamens nearly twice the length 

 of the corolla : filaments bearded : anthers linear-oblong. Ovary ovate-globose, hairy ; the 

 large placenta nearly fiUing up the cell, and surrounding the ovules. Capsule the size of a 

 small pea ; only one of the seeds usually Jirriving at perfection. Testa of the seed areolate. 

 Embryo very small, excentric. 



Moist shady places, in rich soil. Fl. May. Fr. July. The young leaves are said to be 

 eaten as a potherb, under the name of JohrCs Cabbage. 



2. Hydrophyllum Canadense, Linn. Canadian Burr Waterleaf. 



Somewhat hairy ; leaves palmately and angularly somewhat 5-lobed ; peduncles shorter 

 than the leaves ; calyx slightly hairy. — Willd. sp. 1. p. 815 ; Lam. ill. t. 91. f. 2; Michx.

Perennial. Rhizoma creeping. Stem 12 - 18 inches high. Leaves on very long petioles, 

 mostly cordate at the base, slightly hairy above ; the lobes broad, cut and toothed. Flowers in 

 rather crowded corymbose racemes. Segments of the calyx linear-subulate. Corolla white, 

 veined with purple. Stamens, etc. as in the preceding species. 



In rich shady soils, northern and western parts of the State ; common. June. This, like 

 the preceding, is used as a potherb, being one of the numerous vegetables known as greens.

3. Hydrophyllum appendiculatum, Michx. Hairy Waterleaf. 



Stem hairy ; lower leaves pinnately divided ; upper ones palmately lobed ; sinuses of the 

 calyx with small reflex appendages. — Michx. fl. 1. p. ISA; Pursh, fl. 1. p. 134 ; Torr. 

 fl. 1. p. 220; Benth. I. c. ; Hook. fl. Bor.-Am. 2. p. 78. Nemophila paniculata, Spreng.; 

 Beck, hot. p. 256. 



Perennial ? Stem about a foot high, branching at the summit, clothed with rather stiflf 

 spreading hairs. Leaves all on long petioles, the breadth as great as the length, hairy above, 

 pubescent underneath ; the lobes coarsely serrate and toothed. Peduncles shorter than the 

 leaves. Racemes crowded in a corymbose cluster. Calyx hairy ; the segments linear- 

 lanceolate, acute : sinuses with small ovate appendages. Corolla pale purplish blue ; the 

 lobes with a longitudinal adnate scale inside, the edges of which are free and folded inward, 

 thus forming a chink or groove. Stamens shorter than the corolla. Ovary as in the preceding.
