Common Name The Ivory White Colored Dressleria

Flower Size

Found from Nicaragua, Costa Rica and Panama in wet montane forests on low trees along the margins of grasslands at elevations around 570 to 900 meters as a medium sized, warm growing epiphyte with slightly compressed, conical pseudobulbs enveloped basally by several, imbricating, leafless below and leaf-bearing above sheaths carrying 5 to 6, green, plicate leaves that are basally clasping to the leaf sheaths which blooms in the fall on a basal, lateral, to 8" [to 20 cm] long, racemose, to 8 flowered inflorescence enveloped basally by 3, imbricating, inflated sheaths and carrying very fragrant flowers.

Dodson cited all south American species of Dressleria as D eburnea but this has turned out to be false. D eburnea has never been collected in South America. If cited as northeastern Colombia or westernmost Venezuela it is D kalbreyeri. If cited for westernmost Colombia it is D kerryae or D morenoi. If cited as southwestern Colombia it could be D williamsiana but to date it has not been collected there. If cited for Ecuador the correct species name is either D fragrans, D dodsoniana or D williamsiana. D dodsoniana can also be found in northenmost Peru. D aurorae and D bennettii come only from Peru.
