This plant appears to be a large, very vigorous growing Maxillaria tenuifolia. The hybrid Max. Maui Coconut (M. tenuifolia x M. sanguinea) was considered; however, M. tenuifolia is much larger than M. sanguinea, which has smaller, thinner leaves. The hybrid is also smaller than M. tenuifolia and this plant. It's possible this plant could be line bred to produce larger flowers with better substance and may possibily even be polyploid and still within the variability of M. tenuifolia.
