Plants 7.5–18 cm. Leaves 1–2, ascending on base or middle of stem, rather abruptly reduced to 1–2 bracts distally; blade lanceolate to ovatelanceolate or elliptic-oblong, 2.5–8 × 0.8–2 cm. Spikes rather dense. Flowers resupinate, rather conspicuous, yellowish; corolla commonly richer yellow than more greenish calyx; lateral sepals spreading, slightly reflexed; petals ovate to broadly lance-falcate, margins entire; lip descending, elliptic, elliptic-oblong, or elliptic-lanceolate, without basal thickening, 4–8 × 1–3 mm, margins entire; spur slenderly cylindric to clavate, 9–13 mm; rostellum lobes directed downward, closely spaced, parallel, very swollen adjacent to orifice of spur, small, obscure, rounded; pollinaria appearing straight; pollinia apparently remaining enclosed in anther sacs; viscidia oblong, perhaps varying to orbiculate; ovary stout, mostly 6–7 mm.


Phenology: Flowering Jul–Aug.
