Common Name Dolose Cattleya or the Crafty or Deceitful Cattleya

Flower Size to 5" [to 12.5 cm]

Found in south central Brazil near Sao Paulo on rock outcroppings with fusiform pseudobulbs carrying 2, narrowly elliptic or elliptic oblong, obtuse or rounded apically leaves. It blooms in the spring on a terminal, to 3 5/8" [to 9 cm] single to few flowered inflorescence that has fragrant, heavy-textured flowers.

Often thought to be a natural hybrid between C walkeriana and C loddigesii but it has not been able to be duplicated artificially. The major difference between this species and C walkeriana is that the fall blooming inflorescence arises on the apex of a mature pseudobulb while C walkeriana is on a separate immature growth.
