Succulent Scoop Conejo Cactus & Succulent Society October 2021 Volume 6 Number 10 Mission Statement: The Conejo Cactus And Succulent Society encourages the study, CSSA Affiliate cultivation, conservation, and appreciation of cacti and other succulent plants. Email: ConejoCSS@hotmail.com Facebook: Conejo Cactus & Succulent Society Web: ConejoCSS.com Meetings at Last! Monday, October 4th New Meeting Location California Lutheran University Lundering Events Center 130 Overton Court, Thousand Oaks, CA 93021 Doors Open at 6:30 PROGRAM: Thailand: An Unexpected Succulent Paradise Dr. Kyle Williams Most people know Thailand as a Asian country with nice beaches and lots of Buddhist temples. What most people do not realize is that there is a very large community of cactus & succulent enthusiasts that grow rare desert plants in a tropical rainforest climate. Kyle will give a photographic tour of Thailand cover- ing not only the cacti and succulents grown in Thailand but other botanical wonders as well. Dr. Kyle Williams became fascinated with plants as a teenager. He attended college at Cal Poly, San Luis Obispo where he gained a B.S. degree in Ornamental Horticulture. That in turn sparked an interest in botany that saw him earn a PhD from Duke University in Plant Taxon- omy. Eventually Kyle decided to leave the academic world behind and start his nursery, Kyle’s Plants, which specializes in cacti & succulents.
President’s Message: The Succulent Scoop is short this month. Our editor, Melinda Hines, has the opportunity to go on a road trip and timing was too short to do a newsletter with all the photos. Most of the emphasis this month will be put on our ‘New Beginning’. Our first in-person meeting in a year and a half, in a brand new meeting location, and our October sale which also has a new location. We will have plant of the month judging! So bring your Opuntia or Aizoaceae (Mesembs Mesembryanthemaceae) along to the meeting. See Page 4 for Plant of the Month rules. The November newsletter will return to its old format. There will only be photos of the Plants of the Month that were presented at the monthly meetings. We need a volunteer to take the photos because Melinda is “handicapped” in that department. Also, if you have any succulent/cactus related info, stories, poems, trivia or cartoons you’d like to share with members, send it to Melinda ( Loper987@yahoo.com ) for possible inclusion in the Succulent Scoop. For those of you who may still be uncomfortable in a live meeting situation we are going to try and offer a Zoom presentation along with our in-person presentation. The new equipment we have in our new facility allows us to do both, providing we can figure out how to use it. The College assures us that they have technical people available to us at all times, if need be. The Zoom portion of our meeting will only be for Kyle’s presentation, not the whole meeting. As far as refreshments go, we will not start using the alphabet as to who brings the refreshments until January. Anyone who wants to bring refreshments is welcome, but everything must be prepackaged, nothing open or homemade. We will provide water and coffee. Our sale, on Oct. 17th is coming up very quickly. If you have any plants you wish to donate, please bring them with you to the sale. We will need to wear a mask at both the meeting and the sale. Ventura County has mandated that masks must be worn in indoor settings until October 19th. The club is requiring that all people wear masks at our sale. We still need 9 more volunteers, mostly for afternoon time slots. Please call me at (805) 501-0761 to volunteer. We are doing a lot more advertising than in the past, and we have more vendors than ever before, so it should be our best sale yet and we’ll need as many of you who can volunteer to handle the possible crowds. Check out our new club flyer on Page 3. If you are able to post them in prominent locations, it will help to get the word out about our club. I’m looking forward to seeing everyone in person again on October 4th.

Each meeting of the CCSS will feature a friendly plant show/competition (POM). The goal of the POM is two fold. Introduce the membership to the various cactus and succulent genera and to open up a discussion on the culture, care, and display of these plants. Encourage members to share their plants with membership. POM Submissions: Members may submit up to 3 three plants in each of the two categories (Cactus and Succulents). Plants entered in the Intermediate and Advanced Divisions must have been owned and maintained by the member for a minimum of one year. Plants entered in the Novice category may be newly acquired plants. POM Divisions: Novice: 0-25 Total points ● Intermediate: 26-100 Total points ● Advanced: >100 Total Points When a member has accumulated the total number points in their Division, they will be moved up to the next higher Division in the following calendar year. POM Judging Criteria: Plants are evaluated according to the following criteria: Condition (health, form, damage). 50% Maturity and size. 25% Staging (Artistic composition - container, stonework, etc). 20% Nomenclature (proper plant identification). 5% Additional criteria may include rarity, difficulty in growing, and whether the plant is in flower. POM Judging: 1st place - 6 points ● 2nd place - 3 points ● 3rd place - 2 points All other entries will be awarded 1 point. Entry slips will be collected by the POM Coordinator for tabulation, record keeping, and publication in the CCSS Newsletter. We are encouraging all members to participate in the POM. This is your opportunity to show off your prized treasures or to possibly learn how to better care for your plants. See you at the next meeting CCSS Board October 2021 Page 4
Cactus of the Month: Opuntia and Close Relatives Opuntia is one of the largest genera of the Cactaceae (cactus family) and is the most common type of cactus in North America. Plants in this genus form jointed stems that to many look like leaves (but aren't). The most distinctive (and reviled) feature of Opuntia are "glochids", tiny-hair like spines that stick in your skin even if you just brush against the plant lightly. Always have tweezers ready when Opuntia are near! Jointed stems and glochids are found in most of the Opuntioidiae, which consists of Opuntia and several closely related genera (see below). For the sake of the "Plant of the Month" we will include Opuntia and its close relatives. This includes Austrocylindropuntia, Cumulopuntia, Pereskiopsis, Quiabentia, Brasi- lopuntia, Miqueliopuntia, Tacinga, Tunilla, Pterocactus, Puna, Maihuniopsis, and Tephrocactus, and the Chollas (Cylindropuntia). Opuntia (in the broad sense) covers the largest geographical range of any cactus, stretching from Southern Argentina to Canada, and covers all of the Caribbean islands and Pacific Islands from the Galapagos to the Catalinas. It is naturalized on every continent except Antarctica. It is a pest and a noxious weed in many places, and is displacing native vegetation in parts of Africa, Asia, Madagas- Opuntia ‘Sunburst’ car and Australia. Variegated The taxonomy of Opuntia is quite complex and is bound to keep plant taxono- mists busy for years to come! Some of the genera I mentioned above are widely accepted while others are accepted by some and others consider them Tephrocactus geometricus part of a larger Opuntia. Most of the recent changes in the Opuntia group is due to recent DNA phylogeny studies of the species. Propagation of all Opuntias is most easily accomplished by cuttings. All cuttings root easily. Seed propagation requires patience, with seed scarification and sometimes artificial wintering by keeping the seed damp and cold in the refrigerator required. Seed germination can be erratic, with seeds from the same plant sometimes germinating in days, and sometimes not for months or years. Handling of Opuntias is somewhat of a problem due to their glochids. Handling with steel tools is the best bet. Gloves get covered with glochids, which invariably end up in your hands when the gloves come off. Glochids can often be removed by washing with a strong hose stream. Plucking with tweezers is the most effective, especially if you use a good magnifying glass. Other options include brushing, duct tape and rubber cement.

Succulent of the Month: Aizoaceae (Mesembryanthemaceae) or informally Mesembs Mesembryanthemaceae is one of the longest and ugliest plant family names. Thankfully, botanists don't call it that anymore. Now we refer to the family as the Aizoaceae. You can informally call them Mesembs as well. The change in name is due in part to the uniting of plants formally in different families. The Aizoaceae contains over 130 genera and nearly 2000 species, making it as big or bigger than the Cactaceae. Most Aizoaceae are fleshy and succulent plants. While most species that we grow are very highly succulent, such as Lithops, Faucaria, or Ice Plant (Carpobrotus), some genera are just slightly succulent and more resemble a typical herb. Aizoaceae have a worldwide distribution in arid regions, including two species native to California. Despite the family technically being worldwide, the over- whelming number of genera and species (96%) come from southern Africa. It Faucaria tuberculosa ‘Sato’ is interesting to compare the Cactaceae with the Aizoaceae in that both families have developed extreme succulence in order to survive their arid habitats. However, how they went about it shows that evolution can converge on a basic idea in two different ways. Cacti have evolved thick fleshy stems that store water during lean times while also getting rid of big green leaves (except in Pereskia and a few other species) that lose a lot of water on hot days. The leaves of a cactus have been turned into the spines that protect the plant from predators. The Aizoaceae took a different path. The stems have been nearly lost in many species (e.g. Lithops), or tend to be fairly thin and not much for water storage. The leaves have become extremely fleshy to the point where they are practically balloons filled with water. Whereas Cacti "fight" their predators by forming big sharp spines, the small stemless Aizoaceae hide from them by blending into their surroundings. They in essence become indistinguishable from rocks and are therefore ignored by thirsty predators. Another strategy employed by many Aizoaceae is to grow in the cracks of rocks. That gets them away from bigger, faster growing shrubs and grasses that would shade them out, but also helps them survive against predators. If a thirsty animal were to find one of these in the ground they could eat the whole thing killing it. If they find one wedged in a rock they might be able to eat the exposed leaves Conophytum obcordellum but the base of the plant would be protected, allowing the plant to regrow. Our climate is great for growing most Mesembs, though, with nearly 2000 species, general advice for growing all of them is impossible to give. However, for the fleshy leaved South African species basic advice can be given. First of all, you need to know if your plant comes from the winter rainfall regions (which is very similar to our own climate) or from summer rainfall regions. For winter growers such as Conophytum, Cheiridopsis, or Fenestraria you can embrace our climate by letting the winter rains water them from fall through spring and then keeping them totally dry (or nearly so) during the summer. For summer growers like Faucaria, Pleiospilos, or Lithops relatives like Argyroderma and Tanquana keep them totally dry in the winter and water in the summer, except when it is very hot out at which time they should be kept dry again. With few exceptions no Mesemb wants to be wet for any length of time. So if our winters are especially rainy even Titanopsis hugoschlecteri the winter growers might need some protection. Similarly, don't soak your summer growers too often even during the growing season. Please realize that summer and winter growers may vary within a genus. For example, Titanopsis calcarea is a summer grower while T. hugoschlecteri is a winter grower. The plants don't care what genus they are, they care about the climate where they live in nature. When in doubt look it up! Kyle Williams Photo credits: Kyle Williams October 2021 Page 6
