Fragrant Deep Shade WarmLATE Spring

Common Name Heller's Dressleria [Nicaraguan Botanist 1900's]

Flower Size .8" [2 cm]

Found in Nicaragua, Costa Rica and Panama in wet montane cloud forests at elevations around 915 meters as a small to medium sized, warm growing epiphyte with caespitose, conical to elongate conical pseudobulbs carrying green, plicate, erect, narrowly elliptic, acute, gradually narrowing below into the basally clasping leaves that blooms in the late spring on a basal, erect, racemose, 8 to 10" [20 to 25 cm] long, 5 to 12 flowered inforescence carrying fragrant flowers

"Dressleria helleri is most similar to D. dilecta and primarily differs by its shape of the opening to the sac that is cordate and a floral fragrance dominated by beta ocimene and pdimethoxybenzene. Dressleria dilecta has a floral fragrance with alpha pinene, 1,8 cineole and lesser amounts of p-dimethoxybenzene and a more rectangular opening to the sac." Harold Hills 2012

Similar to D eburnea but differs in the smaller cavity of the lip which has a thin, erect, flap of tissue on each side rather than a thickened callus. The column is adnate to the lip to its apex whereas in D eburnea the column is free from the lip for part of its length.
