Dear Mr. Pruski:

The Baccharis situation is a good case of
"you know more than I do". When the Vives
specimens was sent to me I checked out herbarium
and came to the conclusion I did. However I have
not studied the plants in detail nor in the field
and haven't reached the family or gnenus for my
Flora of the Lesser Antilles but my notes indicate
there is a major problem. Frankly I don't know
the distinctions between any of the species. Where
does B. dioca Vahl fit into the scheme. I noted
question marks on Heering's key in Urban Symb. Ant.
If you are working on this group more power to you.
All I can say is it needs work.

Sincerely,	.

Richard A. Howard
