Plant and Flowers

Pseudobulbs Photo by Charles Wilson

Part shade Hot Spring

Common Name Grootings' Dendrobium [Dutch Mining Engineer in Borneo early 1900's]

Flower Size 1/2" [1.25 cm]

Found in Borneo in lowland forests at elevations of sea level to 200 meters as a miniature to medium sized, hot growing epiphyte with basal, almost globose, sulcate pseudobulb giving rise apically to branching stems carrying, terete, almost round in cross-section, almost all arising on one side of the stem leaves that blooms in the spring on a short, successively single to few flowered inflorescence.

This species and D setifolium are very close and may turn out to be conspecific, I await new research to confirm or deny this. If they are conspecific then D setifolium takes precedence.

Synonyms Aporum grootingsii (J.J.Sm.) Rauschert 1983; Ceraia grootingsii (J.J.Sm.) M.A.Clem. 2003
