It is epiphytic, with long and strong rhizomes that are firmly attached to its host.[3] It produces many long cane-like stems up to 60 cm long, with purple spots. It has pointed leaves 6–10 cm long. The leaf sheaths range from ivory to white-yellow, and are spotted dark purple-brown.[4]
It flowers from December to March, with inflorescences containing 2-8 flower clusters and reaching up to 8 cm. The flower petals and sepals are greenish cream-yellow, and the labellums yellow-orange. It also produces fruit capsules from January to August.[4] The seeds are wind dispersed.[3]
Taxonomy
editE. aestivalis is from the family Orchidaceae. Unlike those found elsewhere, the E. aestivalis specimens from the Chatham Islands are not distinct, and seem to grade into E. mucronata.[3]
Distribution
editIt is endemic to New Zealand, and can be found on both the North and South Islands, along with the Chatham Islands and Stewart Island.[2][4] It is found in coastal and lowland forests. It is usually found on low branches and trunks, but can sometimes be found on cliff faces and rocks.[4]
