Paphiopedilum primulinum

A compact, sequentially flowering slipper orchid (section Cochlopetalum) from southern Aceh in Sumatra. It has glossy, plain green leaves. A single stem opens small primrose-yellow flowers one after another for many months. It grows in humus over limestone in warm, very wet hill country, and it is one of the easier and most free-flowering slippers in culture.

Where it grows wild

Grows in humus over limestone, both in shade and in more exposed, brighter spots, in the hill forest of southern Aceh. Habitat details in the literature are brief. Most specimens in collections come from cultivated plants, and there are almost no wild habitat notes.

Culture sources give about 500 m near the west coast and about 1000 m inland. One specimen in collections is labelled 450 m. The measured site carries no usable elevation.
