Common Name The Yellow Lipped Habenaria

Flower Size 1" [2.5 cm]

Found in Malaysia on large semi-exposed, granite boulders as a small to medium sized, warm to cool growing, litho-terrestrial with an oblong tuber with coral-like roots and giving rise top an erect, stem carrying lanceolate-acuminate, unequal, reticulate leaves and blooms in the spring on an erect, lax, racemose to 10 flowered inflorescence with shorter than the ovary floral bracts

CAUTION This species is often cited as a synonym of H rhodocheila along with H ericmichaelii but I feel that all three should be separate species.

Over the years several new species have been cut out of H rhodocheila and include H ericmichaelii, H janellehayneiana, and H roeblenii.
