Dear Silvia - and others who might want the same information:
Elvia Esparza Alvarado is a botanical artist in Mexico and gave an
excellent talk on the history of botanical art in Mexico at our Washington,
D.C. GNSI annual meeting. I suggest contacting her:
Instituto de Biologia, UNAM
APDO Postal 70-153
Mexico City, DF 04510
w: 011-525-622-5687 I suspect one of these numbers is a fax and not a
home number, but this is how they are listed in the GNSI Directory.
Alice Tangerini and Marion Sheehan also might have book recommendations.
They both are in the GNSI Directory.
