In this regard of cultivated species changing so much - line bred orchids (staying within the species and not hybridized often no longer resemble their wild ancestors. The flowers are larger and bulkier and may no longer be suitable for their natural pollinators, instead now evolving to suit the tastes of their artificial pollinators, man. In addition with every generation the seeds germinate more easily and growth is more vigorous and consistent - not in synch with the seasons and vagaries of ancestral climates which may demand some dormancy.
