A classicly bullate species with dozens of raised bullae on each leaf, each with its own special hair protruding from the tip.  This species is native to Vietnam where it grows on limestone cliffs.  I have not found it necessary to add lime to the growing media, and instead make sure to supplement regularly with cal-mag (lime is 98% calcium) and sometimes add a pinch of azomite to the potting media initially.  All in all, it’s an easier species that can even be grown in ambient humidity if acclimated slowly and kept evenly moist.  It does better in higher humidity, though.

Available plants are well rooted in 4″ pots.  They will be shipped potted. The last photo is representative of the size plants available.
