Bulbophyllum rosemarianum

Bulbophyllum rosemarianum is a small epiphytic orchid from India, described in 2001 in the journal Rheedea. It has single-leaved, four-angled pseudobulbs on a creeping rhizome, stiff, erect, fleshy leaves and short racemes of pale yellow flowers that smell of ripe jackfruit or mango. Almost nothing about its habitat is published in accessible sources, so the growing advice is inferred from its relatives in the southern Indian monsoon forests and should be treated as a starting point.

Where it grows wild

The accessible sources say only that it is an epiphyte. The original description appeared in Rheedea, the journal of the Indian Association for Angiosperm Taxonomy based in Kerala, and its closest relatives grow as epiphytes in moist forests of the Western Ghats. That suggests a monsoon-forest epiphyte, but no locality data could be confirmed.

Unknown. No elevation data were found in the sources that could be opened.
