To LATE TO EARLY

Common Name The Warty Brassia

Flower Size 6" or less

This large species is a warm to cool growing epiphyte of open humid, evergreen to semi-deciduous cloud forests on tree trunks and larger branches from altitudes of 900 to 2400 meters that range into Mexico, Guatemala, Belize, El SAlvador, Honduras, Nicaragua, Costa Rica, Venezuela and Brazil with ovoid-conic, furrowed, slightly laterally compressed pseudobulbs subtended by 1 to 2 foliaceous bracts and has 2, coriaceous, elliptic-lanceolate leaves that are conduplicate at the base. It is distinguished from the other Brassia by the green warts on the base of the lip. They flower in the late spring through the early autumn on a basal, to more than 2' [60 cm] long, erect to arching, inflorescence arising on a mature pseudobulb which are strongly 2 ranked and many [10 to 20] flowered and are slightly fragrant of black pepper and need regular waterings and fertilizer year round. The lip of B verrucosa when flattened is oblong-obovate and is essentially unlobed and the flowers are smaller than B brachiata. Plants found in Costa Rica, Panama and South America with this name are either B brachiata [Central America] or B bidens [South America].
