Bulbophyllum pinelianum

Rat-tail orchid

A small epiphytic Bulbophyllum of lowland wet forests from southern Mexico and the Caribbean to northern South America, long known as B. pachyrachis. It is named rat-tail orchid for its thick, fleshy flower spike, which is studded with tiny flowers. It was once found in Florida but is apparently now extinct there. It is a warm-growing plant, easily kept on a mount in humid, bright shade.

Where it grows wild

An epiphyte on trunks and branches in humid lowland and foothill forest. Its specific microhabitat is little documented; the thick leaves and pseudobulbs suggest a moderately bright position in the lower to middle canopy.

Recorded from 15 to 1250 m, with a median of 180 m (57 records), so it is mainly a lowland species.
