Listera cordata (L.) R. Br.
FamilyOrchidaceae — APG family: Orchidaceae
SynonymsOphrys cordata L.
DescriptionUsually about 10 (occasionally up to 30) cm tall, very slender; the 2 leaves in the middle of the stem, cordate to cordate-ovate; raceme glabrous, open, few- flowered; lip deeply divided into 2 linear, spreading lobes, with pair of hornlike teeth at base. Some specimens have greenish flowers, others dark purple to purplish- black flowers; intermediates have not been observed.
EcologyMoist, mossy places in woods or meadows. Described from northern Europe.
The form of the leaves of the Alaskan plant differs from that of the typical plant in being broader in comparison to length and in having longer pedicels [var. nephrophylla (Rydb.) Hult.; subsp. nephrophylla (Rydb.) Love & Love; Listera nephrophylla Rydb.]. This is especially noticeable in specimens from the mainland coast. (Var. nephrophylla is an obscure taxon, perhaps a weak coastal race; plants occurring, for example, in eastern Siberia and in the Yukon are the typical L. cordata.)
