Name:

  • Mitella, from the Latin

  • The common and Latin names come from the diminutive of mitra, which means 'cap' or 'mitre'. Presumably the seed capsule was thought to resemble a bishop's mitre, though one reference suggests that it looks more like 'a tattered French-Canadian toque'! The species name, nuda, means 'naked' in reference to the bare stem.

  • Small rhizomatous and often stoloniferous perennial with scapes 0.7-2.5 dm tall, glandular-pubescent especially upward. Leaves all basal or with 1 sessile or short-petioled leaf below the middle on the scape; blades rotund-cordate to reniform, 1-3.5 cm across, sparingly hirsute at least on the upper surface, crenate on the margin; petioles mostly 2-9 cm long; stipules brownish, ovate, 2-4 mm long. Flowers small, greenish, in racemes of 3-12 flowers; sepals ovate, 1-2 mm long; petals green, pinnately divided into usually 4 pairs of filiform segments, 2-4 mm long; stamens 10; pistil 2-carpellary, stigmas 2, on short divergent styles, ovary ca. 1/2 inferior or less; hypanthium saucer-shaped; pedicels 1-6 mm long. Capsules splitting open widely, the seeds rather few, black, shiny, ellipsoid, ca. 1 mm long. Jun--Jul. Bogs and swamps, often growing among mosses; rare, with records from Bottineau and Pembina Counties, ND; (Labr. to AK, s to PA, MI, MN, ND, MT and WA; also e Asia).

    Leaves - at stem base, few, long-stalked, ehart-shaped to kidney-shaped, 2 - 5 cm across, round-toothed, with scattered, stiffly erect hairs above.

    Flowers - in few-flowered clusters (spikes) at stem tips, greenish yellow, small, saucer-shaped, inconspicuous; petals divided into 4 pairs of thread-like lobes (like television antenna); 10 stamens; appearing in early-summer.

    Fruit - capsules, 2 - 3 mm long, open widely into shallow cups; seeds shiny, black; ripening in late-summer.

  • Small flowers with deeply incised petals in a loose cluster along flower stems. Flowers appear in early June. Leaves are basal, round toothed, with stiff hairs rising straight up (perpendicular) from the leaf surface.
  • usually stoloniferous, leaves cordate to reniform, 1-3cm long, bicrenate, adaxially sparsely hirsute, raceme 3-12- flowered, petals 4mm, laciniate
