LATER
Common Name The Rock Loving Zeuxine
Flower Size .16" [4 mm]
Found in penninsular Malaysia at elevations around 600 to 700 meters on rocks in forests as a miniature to small sized, warm growing lithophyte with a leafy in the lower half stem carrying blunt, elliptic, downward hanging leaves that blooms in the later fall and winter on a terminal, slender, shortly hairy, to 3.2" [8 cm] long, provided with 2 small sterile bracts, rachis very short, about 2 to 6 flowered inflorescence with shorter than the ovary floral bracts and carrying white flowers
Similar to Z gracilis but Z rupestris has 2 larger flowers and a longer neck or claw on the lip
"This characteristic species appears to be endemic to Penang Island. Hooker (1890) mentions the occurrence of Zeuxine flava on Java, I believe based on the above Lobb collection in Herbarium Lindley. Lobb often gave false localities for his collections, presumably to mislead his horticultural competitors. Zeuxine rupestris may be recognized by its few-flowered (up to 6 flowers) inflorescence, labellum with a relatively long (1.8 mm) mesochile, large epichile (6.0–7.9 mm wide) with patent lobules, and large column (3 mm long)."
