Description:
Plants with the appearance of Aeranthes grandiflora Lindl., the peduncles entirely covered by the sheaths, but the mats difference is in the flowers which are half the size of the other species (median sepal 12.5 mm lateral sepals 18 mm; labellum 12 mm.); the leaves narrower (10-20 x 0.6-1,8 cm.); the column foot and the pedicel much shorter. The lateral sepals are oval-acuminate, the labellum cordate-acute, the anther apiculate apically, the auricles obtuse; the pollin oval and the cauda linear.
Habitat:
Aeranthes arachnites comes from low elevations on Reunion Island in the Mascarene group, where it is endemic.

Notes:
A well grown plant of Aeranthes arachnites often carries 6 or more inflorescences and remains in flower continuously throughout most of the summer and fall. In plant size and flower size, it is a "subdued grandiflora." For those who like green flowers, it is a species well worth having.
Distribution:
Mascarenes
