orchids

I've always wanted to grow orchids outside, and here in Mymensingh I finally have both the right climate and the right place.  Our MCC office has many trees that are well suited for orchids -- especially one enormous koroi (raintree).  Below is the first flower -- a surprise, as they usually just bloom in the Spring.  I think this is one from Brother Guilliome, which he collected from Sylhet perhaps?
