Epiphytic on trees. In habit similar to Renanthera storiei. 
Stems erect, 210 to 215 cm high. Leaves distichous, greenish, 
oblong-elliptic, unequally bilobed at apex, 6.5 to 11.3 cm long, 
2.7 to 4 cm wide, 3 to 4.5 cm distant. Peduncles 11.5 to 11.8

Haec varieta floribus omnino badiis neque striatis neque ma-

In habit and flower parts very similar to the species. The 
flowers are essentially the same in size; the sepals and petals
