A selfing of the beautiful alba cultivar ‘Pearl’ of the species harrisoniana. Smaller white flowers held on an inflorescence above the leaves.
ORIGIN/HABITAT: Brazil. Plants grow in riverside and swampy forests along the Rio Paraiba and its tributaries in the western part of the State of Rio de Janeiro from near Alem Paraiba to just east of Campos. They are also found along tributaries of the Rio Muriae to as far north as the State of Espirito Santo. Plants also grow the States of Minas Gerais and Espirito Santo along the Rio Doce. They are sometimes found near sea level, but they are more common at 1300–2600 ft. (400–800 m). Plants normally grow 5–10 ft. (1.5–3.0 m) above the ground on trees with coarse, rough, lichen-encrusted bark. Along with the orchids, these trees are often laden with bromeliads, epiphytic cacti, gesneriads, and other plants. — Source: Charles Baker
