Sorry this fell through the cracks for a couple of days. I was tempted to leave our entry as it's spelled in the Catalogue of Life for the sake of consistency and wait until the CoL revises its listing, at which time we would revise ours, but it's true that sorbifolia (sorbifolium) is one of the adjectival species names that should agree with the gender of the genus name, so I'll change ours to conform to the general rules of Latin grammar.
Shiny-Leaf Yellowhorn (Xanthoceras sorbifolium)
