1 Santa Clara Valley Orchid Society Established 1951 Helping You to Become a Better Grower June 2011 SCVOS Newsletter (please note that links in electronic copies are functional) Speaker Notes June 1st Meeting Longtime SCVOS board member, Ed Nazzal, has been growing orchids for about 27 years. He has a varied collection of cool growers that grow outdoor, and a small greenhouse where he grows mostly paphs and phrags along with few other species. As a retired chemist he has a great interest in the nutritional aspect of orchids. He is also a hiker; he hikes the bay area hills at least once or twice a week, weather permitting. He also enjoys photography so always carry a camera on his hikes to take pictures, mostly of flowers including orchids and other wildlife. We are lucky in the bay area to have so many state and county parks, along with lots of preserves and open spaces. Those areas are great habitats for animals, birds, trees and many wild flowers, including orchids. Of the 32 species of orchids that grow in California, about half grow in the bay area. Some are very rare and probably no longer exist in their original habitat. But if you look there are few species of orchids that are still abundant, and reside not very far from paved roads requiring only very short hikes to view. Ed will discuss some of those, where one can find some of them and will share some pictures that were taken in their native habitats. This promises to be an unusual and very interesting presentation. Who knew that 32 orchids grow in the wilds of California?

7 !"#$%&'()*!&+%&) Dendrochilum (Ddc.) is a genus of epiphytic, lithophytic and, rarely, terrestrial orchids. The name comes from two Ancient Greek words: dendron (tree) and either cheilos (lip) or chilos (green food), which alludes to either the flower s characteristic large lip or the plant s epiphytic growth. The exact number of species varies from source to source, from as low as 100 to 390. The high number can be explained by the fact that some are synonyms or varieties of the same species. They occur at higher elevations in humid rainforests, from Southeast Asia to New Guinea and as far north as southern Taiwan. Acknowledged centers of diversity are Borneo and the Philippines. The genus was first described by Carl Ludwig Blume in 1825, using Dendrochilum aurantiacum. Johannes Jacobus Smith, an eminent Dutch botanist, named many of these orchids. Acoridium and Platyclinis, subgenera of Dendrochilum, used to be separate genera. The other two subgenera are Dendrochilum and Pseudacoridium. The subgenus Dendrochilum has its center of diversity on Sumatra. Pseudacoridium is endemic to the Philippines. The Philippines is also the center of diversity for Acoridium. Platyclinis has it on Borneo. The Philippines, according to the website is the only country where all subgenera are found. The website also added that there are still new species waiting to be described. Members of this genus are characterized by sympodial growth, much like the way Cattleya and Oncidium grow. However, the species can be divided into two groups, the clump formers (e.g. Dendrochilum magnum) and the creepers (e.g. Dendrochilum aurantiacum, the type species). The following is Jay Pfahl s botanic description of the genus: ovoid to 7 cylindrical pseudobulbs that are basally sheathed by brown to green thin bracts and carrying from 1 to 2 apical, tough, erect, lanceolate to elliptic leaves with a slender petiole. The Dendrochilum website states that some Borneo species of subgenus Platyclinis section Eurybrachium have orange, yellow, red and even red suffused with green colored pseudobulbs. Inflorescence is of three types: synanthous (the inflorescence grows with the growing leaf from the developing pseudobulb, e.g. Dendrochilum glumaceum); heteranthous (the inflorescence grows from the rhizome independent of pseudobulb, e.g. Dendrochilum tenellum); and hysteranthous - the inflorescence develops after the leaf is fully developed. Inflorescence can grow to a length of 50 cm in the case of Dendrochilum magnum. Flowers are small, star-like flowers with three petals and three sepals, arranged in two rows on erect or arching pendant racemes. The flowers are scented, which can be classified as either fragrant or smelly. One can only surmise what the pollinator is from the kind of scent a particular species emits. Dendrochilum.com lists the following growing tips for this genus: There should be plenty of air movement. The plants should be kept moist and never be allowed to dry out. Watering should be from the bottom and not from above the plant. Humidity must be high. There needs to be a difference between day and night temperature. Water should have low salinity.
