From the Latin lagena (flask, flagon, bottle) and forma (form, shape), in reference to the shape of the pseudobulbs (in his original description Bailey writes ‘pseudobulb shaped like a Florence flask’).

Racemes with thread-like stems 40–70 mm long, 1–4-flowered. Flowers bell-shaped, 6–7 × 3–5 mm, white, cream or pale green with pink labellum; flowers rarely wholly pale pink. Dorsal sepal hooded, 7–8.5 × 2–3 mm, irregularly warty. Lateral sepals triangular, 7.5–9 × 5–6 mm. Petals obliquely erect, 5–6 × 2 mm. Labellum c. 6 × 3.5 mm, thick, fleshy, curved, blunt.

Clumps small, compact; pseudobulbs flattish, grooved; leaves narrowly oblong; flowers bell-shaped, cream to pale green; dorsal sepal warty; labellum pink, smooth.
