Phaius tankervilleae (Banks) Blume 1856, an old heirloom clone vs a plant for sale in a recent orchid show.

The top photo is of an old heirloom plant that seems to have been in cultivation in Puerto Rico for decades.  The bottom photo is of a plant in an orchid show, last January.  The heirloom clone has flowers that hold their floral segments parallel to the ground so normally one only see the white backing of the floral segments and the lip.  As you can see in the lower photo the flowers of the plant at the show hold their flowers in a way that you can really appreciate their rich coloring, also the flowers are much larger, as is the plant.  A few years ago I brought one of this large and beautiful plants, it thrived as long as I gave it devoted care, the moment my attention flagged the plant produced significantly smaller growths.    Th heirloom plant survives and blooms with a bare minimum of care, such was not my experience with the newer richer, larger colored clones.  The newer clones can produce amazing bloomings, but to perform at that level they need devoted care during their growth phase.

Phaiocalanthe Charlie Khlem, an unnamed clone

I got this plant as a seedling many years ago.  It is quite different from the Phaiocal. Charlie Khlem clones that were available for sale years ago.  It has the virture that it is almost indestructible and blooms consistently with a minimum of care.  This plant has the particularity that flower that develop under hot weather have much less color than those that develop under cooler conditions.
