Epidendrum polybulbon
Dinema polybulbon
Dinema polybulbon is a miniature, fragrant epiphytic (sometimes lithophytic) orchid native to the humid mountain forests of Mexico, Central America (Guatemala, Belize, El Salvador, Honduras, Nicaragua, Panama), and the Caribbean (Cuba, Jamaica). It thrives at elevations between 600 and 3,200 meters. Habitat: Humid mixed forests, specifically growing on trees (epiphytic) and rocks (lithophytic). Characteristics: Known for forming dense carpets of small, egg-shaped pseudobulbs. Synonyms: Often referred to by its older names, Epidendrum polybulbon or Encyclia polybulbon. This species is highly regarded for its compact size, making it ideal for terrariums and mounting, and it typically blooms in the winter to early spring.
