Erect perennial pubescent herbs, with palmately lobed reniform leaves, and small solitary greenish-white flowers. Sepals 3, petaloid, falling away at anthesis. Petals none. Stamens numerous. Carpels 00, each bearing two ovules near the middle, and in fruit forming a head of 1-2-seeded crimson berries, somewhat resembling a raspberry; stigma flat. [Greek, water-acting, from its supposed drastic properties.]

Two known species, the typical one of eastern North America, the other Japanese.

Stems erect or ascending; flowers yellow.

Leaves cordate, generally with a narrow sinus; flowers 3/4'-1 1/2' wide.


C. palustris.

Leaves flabelliform with a broad sinus; flowers 6"-9" wide.
