Doritaenopsis

Doritaenopsis (abbreviated Dtps. in the horticultural trade) is the nothogenus that contains all hybrids between the orchid genera "Doritis" and "Phalaenopsis" (Dor × Phal). 
Cultivation.
A "Doritaenopsis" and a "Phalaenopsis" will appear to the casual observer as the same orchid. And they are cultured the same, except that the spikes should not be automatically cut as they will often use the same main spike for a second blooming. The "Doritis" brings more flowers, flowers that last well into summer, sharper colors, and often multiple spikes. The tradeoff is slightly smaller flowers.
