This information has been extracted from the late Jack Fowlie's article
in the Orchid Digest
"A Revision of the Section Crispum of the Genus Oncidium"
This article, originally published in 1976 will not be readily available to many growers. With
a number of Crispa Species confused, especially crispum and enderianum, I hope this material will be of asssitance. The original
article in this excellent magazine, in Vol 40 No 2 Mar-April 1976, is well worth studying.
Information on Oncidium
