Cattleya leopoldii

This a bifoliate species from Brazil. Is has a closely related species, C. guttata. C. leopoldii gets fairly large, but it is worth the space. The flowers last a long time, and they have a great, spicy fragrance. I acquired this plant from Santa Barbara Orchid Estates.

Francisco Miranda's site has lots of good information about Cattleya species,
including C. leopoldii.
