Aspidistra cryptantha is a species of flowering plant. A. cryptantha grows in evergreen on slopes of limestone mountains in Vietnam between heights of 600 and 800 metres (2,000 and 2,600 ft).
Description
This species is a perennial herb. Its rhizome is creeping, with a diameter of 5 millimetres (0.20 in). Its cataphylls are short-lived, leaving remnants at the base of young leaves. Its leaves are delicate, 1 to 1.5 millimetres (0.039 to 0.059 in) apart, the petiole measuring about 18 to 25 centimetres (7.1 to 9.8 in); the lamina is ovate-lanceolate and acuminate, measuring 17 to 20 centimetres (6.7 to 7.9 in) by 5 to 6 centimetres (2.0 to 2.4 in), and being rounded and cuneate, with several white spots and yellowish nerves in its lower surface. It also counts with 4 to 6 veins at each side.
Its ascending peduncle measures 1 to 2 centimetres (0.39 to 0.79 in); its perigone tube is subgloboid, its greatest diameter measuring up to 7 millimetres (0.28 in), counting with 6 lobes with 2 keels. Its anthers amount to 6 and are subsessile, each up to 1 millimetre (0.039 in) long; the pistil is flat and rectangular, the ovar is indistinct. The style is cylindrical, 2 to 3 millimetres (0.079 to 0.118 in) long, while the stigma is flat and measures 2 to 3 millimetres (0.079 to 0.118 in) in diameter and is 3-lobed, each lobe with a distal lobulum inflexum.
