Growth Form Epiphytic climber with thin, wiry stems.
Roots Adventitious roots produced along the whole stem.
Foliage Fleshy, stiff leaves are ovate to elliptic, (6-) 10-15 x 3-6 cm. Upper surface is medium green and typically has grey spots, while lower surface is a lighter green. Young leaves dull reddish brown with dull grey markings. Plants exposed to very bright light or full sun may have leaves that are completely red in color. 
Flowers Flower resembles a light pink star (the corolla made of hairy petals, 10-12 mm wide) with a smaller, reddish star on top (the staminal corona, dark red in the centre and light red near the tip, 6-7 mm wide). The pollen-producing anther has long, thin, 'tail like' appendages to 3 mm long that are raised above the corona. The inflorescence is composed of 8-12 flowers.
