 Angraecum calceolus
     In nature, this is a relatively widespread Angraecum, found both in Africa, Madagascar and nearby islands. These are nice smallish clumping angraecums. Each time they bloom, they produce more spikes with more flowers. Older plants can even have branched inflorescences. They’re one of the easy-to-grow angraecums to include in your collection. They are in the Gomphocentrum section, which all have smallish, thin (almost see-through), yellowish-green flowers. A “large” plant in full bloom is quite a sight!
