Bulbophyllum argyropus

Silver strand orchid

The silver strand orchid is a miniature epiphyte with clustered pseudobulbs only 5–8 mm long, each carrying a single dark green leaf. It produces tiny whitish to yellowish flowers with an orange lip from August to December. In the current narrow sense it is endemic to Norfolk Island, where it grows high in the pine-hardwood forest on ridges. It wants a mild, humid, oceanic subtropical climate and bright filtered light.

Where it grows wild

It grows on the upper branches of trees in pine-hardwood forest on ridges, and rarely on rocks. The uppermost branches are brighter and airier than the forest interior.

Few records carry an elevation. Norfolk Island rises only to about 320 m, so all its sites are low.
