May 1st: CSSA Webinar

Join us 12PM on May 1st for another CSSA webinar!

Program: Matt Opel: Cape Geophytes: Remarkable Bulbs, Tubers and Corms from Southern Africa

The Cape region of South Africa is home to one of the most diverse and distinctive floras in the world, including a large number of geophytes: plants that grow from underground buds, and have subterranean storage organs such as bulbs or tubers that persist through times when conditions are unfavorable for growth. University of Connecticut botanist Matthew Opel will introduce a selection of species in important groups of Cape geophytes, concentrating on plants from arid areas or with succulent leaves. He will discuss the unusual growth forms and ecological adaptations of these plants, and include information on their cultivation.

April 17th: CSSA Webinar – Crassulaceae of the Trans-Mexican Volcanic Belt

Join us at 12PM CST for another CSSA Webinar with Julia Etter & Martin Kristen!

Since we live in Jalisco on the western side of the Eje Volcanico Transversal, as it is called in Spanish, we will be taking you on a tour from west to east to see as many Crassulaceae as possible that can be found along the volcanic belt. Some of the species such as Echeveria colorata, E. subrigida and Sedum clavatum are highly ornamental and well-known, but others like Villadia ramirezii, Thompsonella garcia-mendozae, and Sedum ocuilense, to name just a few, are much less known and probably even less shown in presentations.

April 5th: Prehispanic Uses of Cacti and Succulent Plants Among Mexican Indigenous Groups

Join us for this month’s NTCSS meeting at 7:30 PM with Dr. Liliana Cracraft!

This lecture presents the importance of cacti and other succulent plants in the process of settlement and civilization of the native tribes of México. These plants were, and in many cases still are an important source of food, drinks, medicinal products, building materials, and many other useful things. An emphasis will be placed on ethnobotany.

April 3rd: CSSA Webinar – Out of the Fire, Into the Pan with Steven Brack

Southern Africa has a huge amount of exposed rock slabs; in these areas are billions of depressions that fill in with grit, sand and other soil types. Many other things also grow in these pans like mosses, other succulents, and other plants.

A whole ecosystem develops in these pans and in part each pan becomes its own little world. Often these pans are small, from a few centimeters to a few meters.

You will see in this program many kinds of small succulents growing in these pans and get an idea of how they survive in nature.

March 20th – CSSA Webinar: The Flora of Baja California Botanical Research and Succulent Diversity with Jon Rebman

Join us at 12PM CST on March 20th for another CSSA webinar!

The Baja California peninsula and its adjacent islands support a wealth of species diversity in many different plant families. As a result of data compiled in the annotated, voucher-based checklist of the vascular plants of the region published in 2016, we know there are approximately 4400 different plants, of which 26% are from (endemic to) the region. Botanical surveys and collecting expeditions are important scientific endeavors that are conducted in order to: improve our natural history knowledge of little-known regions, make new botanical discoveries, facilitate conservation awareness, and improve binational collaboration. Over the last few years, Dr. Rebman has been involved in various expeditions to remote parts of the Baja California region and its adjacent islands.
