Peter Tristram .... "This pic. shows pamelae, a very large specimen too, just behind a specimen of T. samaipatensis, ex Peter Bak - he bloomed the mother plant so it is the real deal. Len Colgan knows all about this species having seen it on cliffs in Bolivia. The plant in the pic is well over 1 m wide. I am not sure how Iíll display it when it finally blooms! Thankfully both produce adventitious pups."
