Bulbophyllum ardjunense

A little-known Javanese Bulbophyllum described by J.J. Smith in 1927 and named after Mount Arjuno in East Java. The only wild record plots near the mountain's upper slopes, so it is presumably a cool-growing montane epiphyte. Treat it as a cool-to-cold, constantly humid orchid and expect to learn its needs by trial.

Where it grows wild

No habitat notes were found. Its name and single record point to the montane forest of Mount Arjuno in East Java, where Bulbophyllum typically grow on mossy branches.

The single record plots at about 3300 m, near the top of Arjuno, but the coordinates are likely imprecise and the real collecting site may be well below the summit.
