Topic: Gillian Evison – A Beginner’s Guide to Caudiciforms

Gillian is an academic librarian and long-time member of the Oxford Branch of the BCSS. Her interest in cacti and succulents started as a teenager and has continued unabated since. She has always been drawn to the sculptural and tactile qualities of caudiciform succulents and has grown them, sometimes with far less success than she would like, for over forty years.

This light-hearted talk introduces some of the caudiciform and pachycaul species most frequently found in UK collections and shares some of the cultivational joys and challenges that come with welcoming the ‘fat plants’ into your life.

Topic: Hazel Taylor – Animals and Cacti of the Galapagos Islands

Time: Tuesday 3 August 2021 at 7:30pm (BST)

Hazel has grown cacti and other succulent plants, and has been a member of the British Cactus and Succulent Society and its predecessor for over 50 years. She has been a member of Bromley Branch since it was founded, and a member of the Branch committee for many years, and is currently its Chair. Hazel strongly supports the Showing and Judging weekend, and since obtaining qualifications in both cacti and succulents (in 2009), she has judged various Branch and Zone shows. In April 2017 she was elected to the BCSS Shows Committee and was elected Secretary in September 2020. Seeing cacti and succulents in habitat is a particular interest, especially seeing them in the context of the other native flora of the region.

No one can visit the Galapagos Islands without enjoying the wonderful wildlife, much of which has no fear of humans. In this talk we shall see many species that are endemic to the islands, including the wonderful land and marine iguanas and some special birds, including the cactus finch. We visit the Charles Darwin Research Station, and also travel to the islands of Santa Cruz, Bartolome, Santiago, Genovesa, North Seymour, Santa Fe and finally Isabela. Along the way we will see the characteristic cacti of the Galapagos, and Hazel will share some recent scientific thinking about the origins of some of those cacti.

Topic: Stephen McCabe – Dudleya Conservation and Cultivation

Stephen McCabe has been studying and visiting Dudleya in the wild since 1983. As Emeritus Director of research at the University of California Santa Cruz Arboretum, he still maintains the Dudleya reference collection he brought there from San Francisco State University, a collection he has added to during his 30-year tenure at the Arboretum. His naming of D. hendrixii, created a viral online sensation. He is currently working on naming several new, rare species. As one of the few people studying Dudleya, he is often consulted by various government agencies about how to protect the many rare species in the genus.

He has written the most recent account of the northern ⅔ of the genus in the second edition of The Jepson Manual, Higher Plants of California. He has published widely on a variety of subjects and his articles can be found in Madroño, the US Cactus and Succulent Journal, Fine Gardening, Systematic Botany, the American Alpine Journal, and the Rock Garden Quarterly.

Dudleya is a genus of plants currently in the international news because poaching to supply markets in Asia and elsewhere are devastating some habitats. Climate change and rampant wildfires also affect some species. It is a group that, including species and subspecies, has about 68 recognized entities. Stephen’s unique and detailed knowledge of this this varied and fascinating succulent genus promises to be of great interest to us whether we are beginners or experts.

Topic: Steven Brack – 'Out of the fire, into the pan'. Miniature succulents of the grit pans of Namaqualand

Time: Tuesday 7 September 2021 at 7:30pm (BST)

Steven became interested in horticulture from a young age while growing up on a small family-run dairy farm in Wisconsin. Seeing some cacti at a friend’s house resulted in trips to the library to look at books on the subject, then in turn joining societies and sending away for seeds. Having developed the seed-raising bug Steven decided to move to the desert state of New Mexico, to start a nursery to produce seeds. Along with his wife, he started Mesa Garden in 1976, which he sold in late 2016 upon retirement. Steven found that one of the best parts of his work was taking trips to see plants in habitat, and this he continues to do.

Southern Africa has vast areas of exposed rock slabs, where there are billions of depressions that fill up with grit, sand, dust. A whole ecosystem develops in these pans with each one becoming its own little world, where succulents, mosses and other plants grow. The surrounding high rocks are very barren compared to the depressed pans; the high rocks are too hot to support the complexity found in the cooler pans. In the western regions of South Africa and Namibia there is a winter rainfall climate with some rain, drizzle, fog, snow, and frost at night. These water sources trickle down into the pans keeping them cool and moist compared to the heat and dryness of the rocks higher up. Some pans fill in with grit that erodes off the higher rocks providing a great spot for slow-growing succulents to grow from seed. The grit provides stability for the tiny seedlings to survive. In this exciting talk we will see many kinds of small succulents growing in these pans and get an idea of how they survive in nature.

Since his youth, Thomas Brand has been associated with cacti and other succulents and has turned his hobby into a profession – he is a trained gardener, a qualified horticulturist and phytopathologist, which means that he deals professionally with diseases and pests on plants. Thomas has been a member of the German Cactus Society (DKG) for 35 years. He is a leading editor of the German-language cactus journal ‘Kakteen und andere Sukkulenten’ and has written a book entitled Plant Protection in Cacti and Other Succulents (in German only).

Like all living things, cacti get sick and are attacked by parasites. In nature, these counterparts are regulators of the natural balance but in our collections, we consider them as pests that we try to combat. The most common of these parasites in a cactus and succulent collection are certainly mealy bugs and spider mites. From time to time, we all experience the challenge of these little creatures, and a greater knowledge of them will be of great interest to beginners as well as to experienced growers. The biology of mealy bugs and spider mites and possible countermeasures will be described and discussed in this talk, which is not necessarily for the faint-hearted!!!

Is it me, or does the link to the talk not work this evening? Is the link provided really the link for tonight and not for some future event?

It keeps saying "The meeting has not started" for a while, and it should have started by now.
