Common Name Ivona's Encyclia [Carnevali's Wife, Describer of species, Current]

Flower Size 1" [2.5 cm]

Found in Bolivar state of Venezuela and Roirama state of northern Brazil at elevations around 700 to 2000 meters in gallery or rain forests in well exposed locations on trees and the rocks beneath them as a medium to large sized, warm to cool growing epiphyte and occasional lithophyte with clustered, pyriform to elongate-pyriform, basally rounded pseudobulbs enveloped in youth by imbricating, deciduous sheaths and carrying 1 to 3, apical, coriaceous, smooth, narrowly lanceolate-ligulate, cymbidiform, basally clasping leaves that blooms in the summer on a terminal, erect, 2 to 3 times longer than the leaves, peduncle half the length, 3' 4" [1 meter] long, paniculate, 30 to 50 flowered inflorescence with triangular, shorter tha the pedicel floral bracts and carrying fragrant, fleshy, long-lasting flowers.

Similar to E chloraleuca but differs by the larger flowers and the longer, paniculate inflorescence. Similar to E oncidioides but E ivonae is flat on the dorsal surface and the lip middle lobe is elliptic-ovate, widest just above the base. The flowers of E oncidioides are somewhat larger. The lip form and size of E ivonae is similar to Encyclia guianensis but the lip callus of the former is flat and the pedicellate ovary is smooth vs the deeply sulcate lip callus and the verrucose pedicellate ovary of E oncidioides. Also the petals of E ivonae are prominently wider .28 to .38" [7 to 9.5 mm vs 1.4 to .2" [3.5 to 5 mm].
