Rarely Seen Cliff-dwellers: Under-appreciated Mexican Crassulaceae

By Julia Etter & Martin Kristen
Tuesday, October 20, 2020 – 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, Julia Etter and Martin Kristen offer us a glimpse of some lesser-known Mexican genera in the Crassulaceae, including Cremnophila, Graptopetalum, Lenophyllum, Pachyphytum, Reidmorania and Thompsonella. These are often overlooked because they can be small, hard to get to, restricted in range, or not as showy as Echeveria laui. Nevertheless, there are some extremely attractive species to be found. Pachyphytum cuicatecanum grows in a protected and difficult to access area in Oaxaca. Thompsonella garcia-mendozae can be found near the Presa de Infiernillo in Michoacan, and Graptopetalum superbum in Jalisco. In Sinaloa, we will see Reidmorania occidentalis, a former Echeveria for which a new genus was described in 2017 by the late Myron Kimnach. We will see pictures of almost all the species and discuss their characteristics.

The presenters hope their photos will encourage you to try to cultivate some of these less common Mexican gems. Most are perfectly suitable for a partly-shaded terrace or a sunny windowsill. Some are great companion plants for agaves (most of them grow together with agaves in habitat) and can be reproduced easily from fallen leaves.

Originally from Switzerland and Austria, Julia and Martin have focused on the Agavaceae and Crassulaceae since 1989, which led to extensive field research starting in 1997. They relocated to Jalisco, Mexico more than 15 years ago, and since 2009 they have been affiliated with the Institute of Biology of the Autonomous Mexican National University (UNAM).  Agave kristenii, Echeveria juliana, and Sedum kristenii are named in their honor. Their photographs and articles have been published widely in books and journals. More info can be found on their websites at globetrotters.ch, agavaceae.com and crassulaceae.com.
