Like most epiphytic orchids, Bifrenaria harrisoniae has a swollen storage organ known as a ‘pseudobulb’ at its base (2)(3). The prominent pseudobulb is conical to egg-shaped and ranges in colour from yellow to green (2). Arising from the apex of each pseudobulb is a single dark-green, pleated leaf, and a one to three flowered inflorescence (2)(4). The waxy petals and sepals of the sweetly fragrant flowers are generally creamy-white to pale yellow (4)(5), while the hairy lip is reddish pink with a deep yellow centre (2)(4)(5).
Bifrenaria harrisoniae tends to grow as an epiphyte in closed forests, but in open areas is often found growing on rocks (2)(4). Its showy flowers can be seen from July to December and are visited by euglossine bees and bumblebees, which almost certainly act as pollinators (2)(6).
