Herbs to 75 cm. Roots fusiform-cylindric, 13 cm × 3–10 mm. Leaves 2–6; petiole erect, 3–10 cm; blade green abaxially and adaxially, narrowly to broadly elliptic, or elliptic-lanceolate, 3.7–13 × 1.6–6.4 cm, apex obtuse to acute-acuminate. Inflorescences immaculate, green to greenish brown; scape to 57 cm × 1–5 mm, glabrous or sparsely pubescent; racemes 7–50-flowered, 7–23 cm, pubescent; floral bracts erect, immaculate or minutely speckled, lanceolate, 8–19 mm. Flowers green to coppery brown, sometimes purplish, tubular-funnelform; sepals basally connate for 0.1 mm, abaxially pubescent; dorsal sepal elliptic-lanceolate, 4.5–7 × 1.5–2 mm, apex acuminate; lateral sepals slightly sinuate-falcate, narrowly oblong, 5–7.5 × 1–2 mm; petals linear to narrowly spatulate, 4–6.5 × 0.5–0.75 mm, glabrous; lip white, canaliculate, pandurate to oblong-ovate, then constricted distal to middle, distal portion flabellate to reniform, usually broadest, or distal and proximal portions equal in width, 5–7 × 2–4 mm, base laterally thickened, with or without pair of tubercles, margins entire or crenulate; column slender, 3.5–4.5 mm; pollinia yellow. Capsules erect-spreading, ellipsoid, 6–12 × 4–6 mm. 2n = 28, 30, 45.

Discussion

Morphologic variation is substantial in Cyclopogon elatus. Variants may be sympatric and locally distinct (J. D. Ackerman 1995), or they may form a continuous series within or among regions. I suspect that inbreeding (via self-pollination) is prevalent and has generated and maintained local variation.

Selected References

None.

Lower Taxa

None.

"broadest" is not a number.
