LATE

Common Name Dillon's Vanilla [American Orchid Enthusiast and American Orchid Society Past President 1900's]

Flower Size 2.4" [6 cm]

Found in Florida, Puerto Rico, Haiti, Dominican Republic, Leeward Islands and Cuba in moist serpentine scrub forests at elevations of 150 to 750 meters as a giant sized, hot to warm growing terrestro-epiphyte with scandent, thick, 8" [20 cm] long internodes, smooth stems carrying fleshy, triangular-lanceolate, somewhat involute, apically hooked, acute, conduplicate, small, bract-like leaves that blooms in the late spring on an axillary, short, several to 8 flowered inflorescence with fleshy broadly ovate, small floral bracts and carrying successively opening, large, showy, ephemeral, fragrant flowers.

"Distinguished by its starry flowers, conspicuously trumpet-shaped 3-lobed lip, edged with rich purple, in which the midlobe is triangular and longer, and with yellowish papillae towards the lip apex. The only known population in Florida has been wiped out, although plants survive in cultivation. Although similar to the other leafless Caribbean species, it is easily distinguished when flowering material is at hand. Vanilla clavicula has an entire lip; from V. barbellata it is distinguished by its larger flowers and much longer midlobe of the lip. Many specimens bear small leaves, similar to those found in V. claviculata and V. poitaei, but rarely seen in V. barbellata. Vanilla poitaei has a larger lip and the margins are crisped."
