A  First it is probably mislabeled. Greg Allikas, the AOS webmaster, is a bit of an authority on C. guttata and Cattleya leopoldii and he notes two major points of difference that any hobbyist can detect. Cattleya leopoldii will make up its growth and immediately flower, whereas C. guttata matures the growth and then blooms from a dry sheath. Second, the pseudobulbs of C. guttata will occasion ally have three leaves, whereas C. leopoldii always has two. I have never seen an alba (green with white lip) C. guttata, but C. leopoldii alba ‘Bracey’s Variety’ is famous. When first advertised in the AOS Bulletin (now Orchids), the color was inaccurate, so the advertiser, B.O. Bracey, insisted that a single page with the correct color be sent to every sub scriber. Talk about maximum impact. Huge sums were paid for plants and, more important for Bracey, the seedling progeny sold well. Cattleya leopoldii var. alba is extremely difficult to maintain in culture but I am pleased to report that the newer strains seem to be adapting to greenhouse culture better. My advice for handling the plant over winter is to provide bright light, keep it on the dry side, and always repot right after flowering in the summer. Enjoy your plant — it is beautiful and still rather rare.  -- Andy Easton.
