Program Description

Join Guillermo Rivera on a recent journey to the western and southern part of Madagascar. The island is rich in endemism (plants and animals that are only found in this place). Lemurs and chameleons are almost exclusively found in Madagascar. Among the plants we will encounter, the genus Adansonia (the baobab trees) is perhaps the most famous, but there are plenty of representatives of other genera, such as Aloe, Euphorbia, Didierea, Alluaudia, and Pachypodium.

Guillermo was born in Argentina. He is the owner of the tour company Plant Expeditions, and for the last 17 years, has led trips throughout South America, Mexico, Southern Africa, and Madagascar. These tours have an emphasis on plants: bromeliads, orchids, cacti, and other succulents.

Upcoming tours planned for 2021: Argentina (November). For 2022, we have Ecuador (January), Socotra (March), Baja California (April), Namibia (May), Central Brazil (July), South Africa (August), Madagascar (October), and Chile-Argentina (November).

If you wish to be kept informed about our future trips, please email Guillermo at:
