Overview
Caespitose epiphytes. Pseudobulbs ellipsoid, of several nodes, wrinkled-grooved with age. Leaves 2--3, apical, linear to oblanceolate. Inflorescences axillary, erect, pedunculate panicles, the floral bracts inconspicuous. Dorsal sepal and petals free, spreading, the lateral sepals completely fused. Lip unlobed or three-lobed, clawed (hypochile), the claw boat-shaped, fused to the column for half its length, the blade (epichile) usually violin-shaped, with small central keels. Column club-shaped, with elongate linear parallel wings, the anther with a large wing-like hood; pollinia 4, in two pairs, on a narrow common stipe and minute viscidium.
Etymology
From the Greek akris, meaning locust, and opsis, meaning appearance, for the supposed resemblance of the column to a locust.
Distribution
A genus of six species distributed from northeast India to Australia and the Solomon Islands.
Care and Culture Card
See basic growing conditions and care information below.
Plants of Acriopsis grow equally well in pots or baskets using a medium grade epiphyte mixture or when mounted on slabs. Provide bright light levels and intermediate temperatures. Water frequently when in active growth allowing the potting media to almost dry out between waterings. After the pseudobulbs have matured, water less frequently allowing the potting medium to dry out fully between waterings.
