        Yes this is the same plant. Whether it's a new species or not is
still a bit doubtful in my mind, especially the plants from Itacambira.
Itacambira is the only place where I've found both "normal" G.violacea
(which is common over most of the Minas Gerais state and is usually
annual in the wild) and this giant form (which I've only found in a few
northern mountains of the same state and is usually perennial). I have
not yet been able to determine if these two forms hybridize or not at
Itacambira.

        To add to the confusion, I've also found at Itacambira some
specimens of a G.uncinata-like plant (new species?) which I've only seen
in one other site at the Serra do Cipo, much further south. Although
they are all closely related, I doubt that the "Giant G.violacea" (or
G.sp."Giant, Itacambira", however you like) is a hybrid between common
G.violacea and this G.uncinata-like taxon, since it does not have
intermediate characteristics and because at the Serra do Cipo I've seen
both growing near each other, but none of these "Giant G.violacea".

       But it's still a bit fuzzy in my mind and I'd like to return to
Itacambira for further study. There are a few other mysteries waiting to
be solved at Itacambira, which seems to be the merging point between the
different CP floras found in the northern and southern parts of the
Serra do Espinhaco mountains which cross the state of Minas Gerais.

Best Wishes,
