Ecology & Life History

General Description: Broad-lipped twayblade is only 5-10 inches tall with two, opposite, elliptic to nearly round, green leaves that are perpendicular to the stem. The stem above the leaves is whitish glandular hairy with up to 20 flowers that have a small lance-shaped leaf at the base of each flower stalk. This small green sepals and petals bend back from the dominant lip that is about 3/4" long, light green with a darker green center, narrow at the base and wide at the tip. Two shallow lobes at the tip make the lip resemble the folded wings of an insect. Sometimes there is a small tooth between the lobes. Reproduction by runners sometimes produces large colonies of plants.
Technical Description: From CNHP Wetland Guide 2012: Growth Habit: perennial, terrestrial; 5-37 cm, somewhat stoloniferous.
Stem: green, succulent, glabrous
Leaves: Leaves: blade green, broadly ovate to elliptic, oval or suborbiculate, 2-7 × 1.5-5.8 cm, apex obtuse to rarely acute or apiculate.
Inflorescences: 5-20-flowered, lax, 20-120 mm; floral bracts semi-translucent, rhombic-ovate to lanceolate, 3-5 × 1-2.5 mm, apex acute to acuminate; peduncle and rachis densely whitish glandular-pubescent.
Flowers: yellowish green, sometimes faintly tinged with purple; pedicels slender, 2.5-7 mm, glandular-pubescent; ovary glandular-pubescent, becoming glabrate as it matures; sepals and petals reflexed away from column and lip; dorsal sepal ovate-lanceolate to elliptic, 4.5-5 × 1.5-2 mm, apex obtuse to acute; lateral sepals lanceolate, falcate, 4.5-5.5 × 1.5-1.8 mm, apex acute to obtuse; petals linear, falcate, 4-5 × 0.8-1 mm; lip cuneate, apex dilated and shallowly notched, lateral lobes rounded, with small tooth in sinus, tapering to short, slender claw, with indistinct triangular tooth on either side of base above claw, 8-13 × 5-7 mm, margins minutely bristly-ciliate; column arcuate (curved like a bow), slender, 2.5-3.5(-4) × 1 mm, apex slightly expanded
Fruit: capsules ellipsoid, 8x5 mm, essentially glabrous.

Diagnostic Characteristics: From CNHP Wetland guide 2012: Main Characteristics:
·Lip petal gradually narrowing to the base, without a fleshy ridge
·Leaves suborbiculate to broadly ovate, 1.5-6 cm wide
·Lip with short claw, not sessile

Habitat Comments: Moist sites along steams and lake shores (B74WEL01AKUS).
