Grassland Sun-orchid

Grassland Sun-orchid

Thelymitra basaltica


Sun-orchids are deciduous terrestrial orchids with a single erect basal leaf. In this species the leaf is long, very fleshy and distinctly ribbed. The leaf is generally longer than the inflorescence. The labellum is the same shape, size and colour as the sepals and petals. Characteristics of the column generally assist in distinguishing between Thelymitra species.
