Oncidium pumilum / Trichocentrum / Lophiaris

[euplusia]

A plant with succulent leaves and miniature flowers of 3 mm of size. Taxonomists are struggling about the name of the genus.
Initially I grew it mounted on a vertical limb. After 3 years of good success the center of the plant grew too dense and started to rot. So I had to take it off. Now I keep it in a netpot held by a skewer without any potting medium. Maximum air circulation kept the plant healthy for years.
