The origin of this plant is unknown. It was purchased ar 
Mr. Walter a = Be gh om some years ago, from ; 
Bull, under the c. Gardneri, from which species “tt is 
entirely different. Bite as bore that name, it probably is a native 
of the same region and doubtless was introduced from some part of 
India or the Malay Archipelago. Mr. Ledger has assiduously 
collected and cultivated the species of this interesting genus for 
many years.
