Common Name or Meaning The Beige Aerangis with Red Spots
Flower Size 1 to 1 1/4" [2.5 to 3.1 cm]
This miniature to just small sized, epiphytic species is found in the Central African Republic, Cameroon, Congo, Zaire, Ethiopia, Kenya, Tanzania and Uganda in riverine forests on small twigs and branches of bushes and trees, rarely on trunks at elevations of 1250 to 2200 meters and appreciates a humid environment. Aerangis leutoalba has flattened roots, a very short stem carrying several spreading, more or less distichous, linear, curved, fleshy, unequally bilobed apically leaf that are all set in the same plane leaves and can be mounted such as this one, on cork or tree fern. They can bloom in the winter or spring and they have fragrant flowers in two flat rows, on a axillary, to 14" [40cm]long, fractiflex, arching or pendulous inflorescence with small floral bracts.
In the summer the plant is in full growth and they need high humidity and plenty of water and fertilizer until mid autumn when it should be reduced, but not to the point of being dry.
The photo above is of the variety rhodistica, to date I have not seen a photo of the type.
