Dear Fernando,
Thanks for your carefully cut pieces of information on your field
exploration in Brazil. I have a few questions or comments regarding
part 15 which might be of some public interest.

Why did you exclude _D. capillaris_? Just because this was not
at the coast? Seeds would be of very much help in this case. Any
chance to obtain some sometime?

Both _D. capillaris_ and _D. brevifolia_ and especially _D.
intermedia_ are more widely spread than these species (they extend
beyond S America) but they are of course less frequent in S Am (or
less frequently identified correctly?).
Kind regards
