Flower Size .4" [1 cm]

Found in the Cameron Highlands of penninsular Malaysia, as a mini-miniature sized, sized, warm to cool growing epiphyte with a short stem carrying a few, not fleshy, ovate, bilobed apically, carrying 6 to 8, slightly unequally bilobed leaves that blooms in the summer on a 1.68" [4.5 cm] long peduncle, rachis to .32" [8 mm ] long, successively single, to 10 flowered inflorescence with broadly triangular, purple floral bracts and carrying flowers with white tepals very faintly tinged with mauve, the lip orange with dark crimson calli and a white column.

The most significant difference between this species and T brevicapsularis is the large triangular, cone like structure at the lip base instead of a clawed non saccate lip base of T brevicapsularis
