The Oncidium alliance consists of many genera of orchids. Although some of these will not breed together there are many that have been combined to form the group of hybrids available now known as the Oncidium Intergeneric Alliance. The species involved in this have got a great deal of variation not just in the flowers, but in plant size and cultural needs. In this video I will try to get at least a basic grasp in the variety of this group. Please feel free to respond. I hope you enjoy it! ...Wade
