Plants are near flowering size 1” – 2” seedlings. With good culture expect these to flower in season 2018. These are mounted on small branches (see last photograph).
This species is native to northern Madagascar and the Comoros Islands. This is a small species that will begin to flower when the plants are 2½” – 3” across. Eventually the plants will mature at 4½” – 5”. Inflorescences are 3” – 5” long and carry 2-4 flowers each. Individual flowers are 1¼” – 1½” across with a 4½” – 5” long spur. Sepals and petals are white to cream with the basal ½ dark bottle green. The labellum is white or cream with a yellow throat. The spur is white or light green. Like the related Aerangis they like HUMID conditions but not “wet feet”. A soggy medium will lead to root loss. As a result plants are often mounted or planted in small slotted plastic baskets.
