Mitella diphylla L.
Common Name: BISHOP'S-CAP
Coefficient of Conservatism: 8
Coefficient of Wetness: 3
Wetness Index: FACU
Physiognomy: Nt P-Forb

Typically in rich deciduous forests, often in wet hollows or slopes; also in swamps, sometimes even cedar swamps.

Ordinarily easily recognized by the pair of opposite, horizontally oriented sessile leaves above the middle of the stem; very rarely plants occur with the cauline leaves 3 or only 1, or aborted, or (more often) with short petioles. In the prominent acute terminal lobe, the leaves are more like those of Tiarella than M. nuda. The rhizome is stout, and the whole plant taller than M. nuda, though the flowers are a little smaller, and the pedicels usually a little shorter (ca. 1.5 mm or less at anthesis).
