Bifrenaria harrisoniae semialba (3 clones)
 

Three different clones of Bifr harrisoniae semialba: the first one is in fact the only really s/a (it has nothing pink in petals); the following two clones have some pink color in the petals and sepals

Frederico, you grow some beautiful Bifrenarias. Those are some nice clones. :)

Cool, love the detail showing the hairs on the lip.
