Diversity of Cacti of Central Brazil

With Guillermo Rivera
Tuesday, February 16, 2021 – 7:00 pm Pacific Time


NOTE: This month’s presentation will be held online. Zoom login information below. Our in-person events are suspended until further notice.

This month’s presentation will focus on the variety of cacti in Central Brazil, particularly the states of Minas Gerais and Bahia. The habitats of Cerrado, Caatinga, and Atlantic Forest are well represented in these states, allowing for a great diversity of many Brazilian genera: Uebelmannia, Micranthocereus, Melocactus, Pilosocereus, among others. Our guide Guillermo Rivera will take us on a journey of over 4000 km, and promises it is worth the drive!
