Sepals and petals greenish white, lip pure white, spotted brown. West Indies B. verrucosa (Mexico and Guatemala) sepals and petals pale transparent green; lip white, with green warts. B. Gireoudiana. This is the handsomest species that I have seen. Comes from Central America. The flowers are bright orange yellow spotted with reddish orange. Flower stems two feet long.

There are several other species, differing from the above slightly, in marking. They mostly bloom in the Spring, just before they commence to make new growth; but they do not always do so, as the Guiana varieties will bloom twice a year if handled properly.
