Asplenium caudatum

A spleenwort of the Society Islands and Marquesas in French Polynesia. Herbarium records put it in wet montane forest at about 430–1200 m on Tahiti and Moorea. It wants mild, even temperatures, high humidity and dappled shade.

Where it grows wild

Wet montane forest and ridges on high volcanic islands. Specimens cite Tahiti at about 1200 m, a southern ridge near 650 m and Mt Muaroa on Moorea at 429 m. We could not confirm whether it grows on trunks or on the ground, so the growth form is an estimate.

Records span 429–1085 m, median 884 m (15 records). One old Tahiti specimen is labelled about 1200 m.
