Grammatoheadia Boynton Leopard a cross of Grammatophyllum elegans and Bromheadia findlaysoniana

Under my climatic conditions, at a 1,000 feet of altitude, near the center of the island of Puerto Rico, this hybrid has proved to be easy to grow.  However it demands good fertilization if the pseudobulbs are to grow to blooming size.  That is the trick with growing and blooming these orchids, when they are in their growth phase they need regular watering and fertilizing coupled with bright light to produce pseudobulbs large enough to bloom.  If neglected they will grow but their pseudobulbs will not reach their full potential and they might not bloom.  This plant gets full sun in the morning from 8:00 am until 11:00 am.  After the pseudobulbs reach their full size I stop fertilizing.  It is a cross between a Grammatophyllum and a Bromheadia, but I see little of the Bromheadia in these flowers.
