The New York Public Library has digitized and put online The Orchidaceæ of Mexico & Guatemala by Jas Bateman. This rare book was published 1837-1843 by James Ridgway and Sons. The prints are quite beautiful, as these examples suggest:
Oncidium leucochilum. [White-lipped oncidium]:
Stanhopea tigrina. [Tiger-like stanhopea]
Cattleya skinneri:

Those are amazingly beautiful. Here in Phil, we also have rare and special kinds of orchids which I hope someday would be given the same attention.
