Hello and greetings to all new and current members.
As you can tell by the photo above the Annual NVOS Potting Party was a huge success and enjoyed by all in attendance. In the top photo, Tom takes his time mixed with his charm and assist a new member of the society with repotting her Phal. as a crowd watches. A special thanks to all potting volunteers, Vinton, Paul, Tom, Kathleen and Karen for guiding all those who needed re-potting. We potted 28 orchids and had over 55 in attendance, mostly guests from the previous month's show. Looking forward to seeing all of you at the next meeting.
The Napa Valley Orchid Society would also like to take a moment and welcome all new members who joined the society as of the April Show and Sale. These new orchid enthusiasts include the following:
Cathy Clark-Enfield, Melissa Marovic, Berit Muh, Marie Krein, Bonnie Gibson, George Watson, Haydee-Rose Reisland, Jean Davis, Katherine Buckman, Frances Thompson, Karen Gunst, Julie Gra, Elizabeth Partch, Christy Kramer, Luta Cathy B. Clark, Chris Baker, Blanche Thiman, Billie Harrel, Jeanette Wiegal, Linda McGee, Lauren Harris and Victoria Avanesova
Welcome one and all to the Napa Valley Orchid Society, and hope your ready for a full year of going crazy for orchids. This is why we asked "got orchids?"
The next meeting of the Napa Valley Orchid Society will take place on May 8th, from 7-10 pm at the Senior Center in Napa and will feature Janet Lamborn and her presentation “Don’t put on the virus blinders, your collection is depending on you”.
IN MEMORY OF FRED SHULL
The Napa Valley Orchid Society notes with great sadness, the passing of a truly great Orchidist, Mr. Fred Shull.
Fred was a great grower as well as a well respected AOS judge who was always very generous with both his time and his considerable knowledge.
Fred Shull will be missed.

If you are celebrating a special event this month, do so with this month's official orchid, the Masdevallia.
Masdevallia, abbreviated Masd in horticultural trade, is a large genus of flowering plants of the Pleurothallidinae, a subtribe of the orchid family (Orchidaceae). There are over 500 species, grouped into several subgenera. The genus is named for Jose Masdeval, a physician and botanist in the court of Charles III of Spain.
Range and morphology
These plants are found from Mexico to southern Brazil, but mostly in the higher regions (2,500-4,000 m ASL) of the Andes of Ecuador and Colombia, Peru and Bolivia. They may be epiphytes, terrestrials or growing as lithophytes on damp rocks.
The plants are characterized by an abbreviated to elongate and creeping rhizome that gives rise to stems that lack pseudobulbs. The stem bears a single, fleshy, erect to pendent, ovate to lanceolate leaf. The flowers are triangular and occur singly or in racemose inflorescences. They are characterized by a showy calyx and reduced corolla. The sepals are fused at the base and frequently caudate. The petals flank the semiterete column and the tongue-shaped lip is flexibly hinged to a free column foot.
The species are sensitive to inappropriate cultural conditions and will show signs of stress by leaf spotting or dropping. They can generally be grown in pots with sphagnum or seedling grade wood chips although a few species produce descending inflorescences and are best accommodated in baskets. In both cases the rhizome should remain at the surface of the medium in order to prevent rot.
Most of these plants are from high altitude cloud forests and require very cool conditions and abundant moisture throughout the year. They cannot tolerate dryness, low humidity, or excessive temperatures and the plants are very easy to kill. They will simply drop all their leaves and suddenly collapse if allowed to dry completely or are exposed to high temperatures. Many members of this genus from very high altitude cloud forests defy cultivation. Most of the species from this genus are considered less difficult in cultivation than plants from the genus Dracula, and some of them are very easy to cultivate and have a 'weedy' habit such as Veitch's Masdevallia, but the majority of these species are usually very difficult to maintain in cultivation unless the plants can be kept cool and moist all the time.
Low humidity conditions or watering the plants with a water source which contains high levels of dissolved salts will result in the leaves yellowing and rapidly dying from the tips back to the rhizome. The plants should be provided with rain water or distilled water or a very pure water source. The medium should always remain moist as the plants do not have any significant storage structures like most orchids.

THE MAY GENERAL MEETING - Friday, May 8th at 7:00PM
DINNER WITH THE GUEST SPEAKER:
Starting at approximately 6:30PM, The NVOS Plant Doctor will be available to consult unhappy plant owners and offer suggestions to make it a happy plant.
A large selection of orchid potting supplies will be available at this meeting. A portion of the sales is donated to the general fund of the Napa Valley Ordhid Society. Bark, bark mixes, fertilizers and pots of all sizes will be available. If you are looking for something in particular, or need to buy bulk, please let the web site know by sending information or questions to:
Our guest speaker this month is Janet Lamborn and she will be presenting “Don’t put on the virus blinders, your collection is depending on you”. We’re going to look closely at each viral pathogen, what it looks like and how it’s transmitted. We will also talk about sanitation practices, testing options and what to do with those results.

Orchids are suceptible to a variety of biotic and abiotic agents that can hinder their development and diminish the quality of their leaves and flowers. Among biotic agents, fungi, bacteria and viruses are the most important. Viruses are organisms invisible to the naked eye that can be seen only through transmission electron microscopes, which can amplify their images several thousand times.
Some 30 different viruses have been reported infecting orchids in various regions of the world. Of those, Odontoglossum ringspot virus (ORSV) and Cymbidium mosaic virus (CyMV) are considered the most important ones due to their prevalence, worldwide occurrence and the severe symptoms they can induce in several orchid genera, often reducing their vigor, lowering flower quality and leading to economic losses. Mixed infections are quite common, because these viruses have similar biological and epidemiological characteristics and are frequently transmitted together.
General safe practices will prevent the spread of a virus from plant to plant. Humans are the biggest transporter of viruses. This happens when an orchid grower seriously tends to an orchid, be it repotting, trimming dead material or even just rearranging the greenhouse. Tonight's presentation will cover identifying an infected plant, how to handle the infected plant, as well as sterlize space and equipment after handling a suspected or known virused plant.
Keeping Your Orchids Pest- and Disease-Free
The Society encourages members to participate once a year in joining a few others in providing those delicious snacks and treats. It is also expected that you help and assist our snack coordinator Carolyn N. in setting up, maintaining during, and cleaning after the meeting.
