ounded in 1940, the Epiphyllum Society of America (ESA) was the first society devoted to the study and promotion of epiphytic (tree dwelling) cactus hybrids and species. Anyone interested in these beautiful and unusual plants is welcpme to join.

ESA meetings are informal and informative, with an emphasis on epi culture. Admission and parking are free free. Refreshments are served. Members and guests attending their first meeting receive a free, potted epi. Plants, cuttings and potting supplies are available for bargain prices at the sale and raffle tables. Meetings are held the first Tuesday of each month (except January and December), at 7:30 p.m., in the Lecture Hall of the Arboretum of Los Angeles County, 301 North Baldwin Avenue, Arcadia, CA. From the Foothill Freeway (I-210), take the Baldwin Avenue off-ramp south, and follow the signs to the Arboretum, Annual events include the National Flower Show; the New Registration Slide Presentation & Silent Auction; the December Holiday Banquet; and monthly programs.

With ESA Membership comes your subscription to The Bulletin, the Society's quarterly publication. The Bulletin is the most newsworthy epi society newsletter available. Each issue has a color cover photograph and regularly features culture tips; the calendar of events, program previews and highlights; plus informative articles of interest to epi enthusiasts. Interviews with epi hybridizers and nursery owners are included, along with technical or scientific articles. The Bulletin is the only epi society newsletter archieved by the Smithsonian Institute, the U>S> Department of Agriculture Library; the Royal Horticultural Society, and botanical libraries around the world.

The ESA has the distinction of having been appointed International Registration Authority (IRA) for epi hybrids by the International Society of Horticulural Scientists. As IRA, the ESA is responsible for registering epi hybrids and establishing their names, and publishing the international registry, Directory of Species and Hybrids. The 1996 4th edition contains more than 7,000 epi flower names, descriptions and vital data. The Species Section list was compiled by Myron Kimnach, an internationally respected taxonomist, editor of the Journal of the Cactus & Succulent Society of America, and Director Emeritus of the Huntington Botanical Gardens. Every cactus species known to be epiphytic is included, making it an indispensable reference source for botanist and the hobbyist, alike.

Each year, the latest flower registrations are published in an Addendum to The Directory, anddistributed with the December issue of The Bulletin. The Addenda update The Directory between editions. Only ESA Members receive them as a benefit of membership.
