Featured Speaker for June 2015

We are pleased to have Mary Gerritsen as our featured speaker at our next general meeting on Tuesday June 9th. Mary’s presentation will be, “Trekking to the Lost World: Mt. Roraima”

Mt. Roraima is the tallest of the tepuis, table top shaped mountains found in the Guiana Highlands of South America. Located at the corner of Venezuela, Brazil, and Guyana, Mt. Roraima is one of the few tepuis thatP1020181 can be climbed without climbing gear or a helicopter. The tops of the tepuis are geographically isolated from one another, and from the rainforest below, and as a result, harbor endemic flora and fauna found nowhere else in the world. These mesas are poor in nutrients, but incredibly rich in carnivorous plants, orchids, bromeliads and other often primitive species, and are a fascinating place to explore botanically. Mary joined a small group led by Stewart McPherson (author of numerous books on carnivorous plants) to go on an adventure of a lifetime. Join Mary for a virtual trip to the Lost World..a true floristic adventure.

Mary has been growing orchids on and off for the last 35 years, and since moving to the San Francisco area in 1997, she has become a passionate orchid hobbyist. She loves miniature orchid species, and has a large collection, mostly pleurothallids, in her cool-intermediate greenhouse in San Mateo. She also grows a large number of monopodials, bulbophyllum, and laelinae in a second larger intermediate-warm greenhouse. She has co-authored, with friend and photographer Ron Parsons, several botanical books including “Masdevallias, Gems of the Orchid World”, “Calochortus. Mariposa Lilies and their Relatives” and most recently, the two volume series “A Compendium of Miniature Orchid Species”. Mary’s favorite vacation is to visit orchid habitats where ever she can to see how orchids grow in their native environments. Thus far Her journeys have led her to Ecuador, Peru, Venezuela, Colombia, Panama, Costa Rica, Mexico, parts of the US, Australia, Borneo, Thailand, Sulawesi, southern and western China, and South Africa. Mary also occasionally writes articles for Orchids (AOS magazine). She is a past-president of the San Francisco Orchid Society and Peninsula Orchid Society.

Mary will also be providing our opportunity table!
