Dendrobium Gina Perlite 'Crystal White'

Dendrobium Gina Perlite is a hybrid of Dendrobium cuthbertsonii and Dendrobium prasinum.  It has, more or less, the growth habit of Dendrobium cuthbertsonii, though the leaves do not have the pebbled surface of that species and the growths are generally a little fatter and larger.  Its flowers certainly look like the flowers of Dendrobium cuthbersonii.  The pale yellow flowers are 4 cm long and 3 cm across the face of the flower, but the clonal name is misleading since the flowers are very definitely not crystal white.
