Common Name Leibold's Tolumnia [German Collector 1800's]

Flower Size about 1/2"

Found in Cuba and the Cayman Islands in bushes at elevations around 800 meters as a small sized, equitant, hot to warm growing epiphyte that is found with flattened pseudobulbs and linear to lanceolate, triquetrous, coriaceous leaves and has an erect lateral, wiry, short to 12" [to 30 cm] long, raceme or panicle of several to many flowers occuring in the spring.

This orchid is now considered to be a synonym of T variegata but I have left them separate pending more investigation. The First photo shows the lip with serrate margins and is quite different from T variegata, the second photo shows a more typical T leiboldii.
