Madison Orchid Growers’ Guild
NEXT MEETING MARCH 25TH: JOHN CLAUSEN WILL SPEAK ON CATTLEYAS MESSAGE FROM THE PRESIDENT Orchid Quest 2007 has come and gone. How fortunate OGG was not to
have encountered the snow emergency of the recent weekend in Dane
County and the Madison area February 3rd-4th.
I want to let you know what a privilege it was to have worked with
you that first weekend in February. I did not
know what to expect because I was abroad the past two years of Orchid
Quest. It was very gratifying to see the guild working as a TEAM to
make this enormous event a success. Many people spent Friday,
Saturday and Sunday working at the Exhibition Hall at various stations.
Many of those same persons went to their paid jobs on Monday
morning. I give all of you a pat on your back for your dedication and
hard work. Attendance at Orchid Quest was down approximately 600
people compared to last year because it was so cold. Nonetheless, I
consider that it was a successful show. The vendors were generally
satisfied with their sales. Treasurer Don Fago tells us that we will be
close to $1,000 in the black after all the bills are paid. This is the last month to renew your membership to OGG. This
application can be down loaded from our website and mailed to Box
5432, Madison, WI. 53705. I look forward to seeing you at Olbrich as
we learn the secrets of growing cattleya orchids in March.

NOMINATIONS ARE OPEN A nominating committee has been selected. It is comprised of Judy
Stevenson, Lorraine Snyder and Sarah Lundey. Positions that will be
open are vice-president, secretary, and one board member. CULTURE SHEETS FOR MARCH AND APRIL AVAILABLE FROM AOS The coming change of seasons cannot arrive too soon. With this
change, our orchids need our attention. The AOS website contains a
monthly checklist for selected genera including cymbidiums, pleuro,
Milton, paph, lycaste, dendrobium, phal and cattleyas. See
http://orchidweb.org/aos/orchids/page22.aspx. ILLINOIS ORCHID SOCIETY AND MID-AMERICA ORCHID CONGRESS This April there is a rare opportunity to attend the IOS and MAOC at
their Spring joint meeting at the Chicago Botanic Garden. The OGG is offering to
charter a bus on Saturday, April 28 if there is enough interest. Consider the
convenience of avoiding a long drive by riding with fellow members in
comfort and with room to transport back your finds! There will be at
least 30 vendors and perhaps two from Peru and Ecuador that have
tentatively agreed to attend as well. Those of you who prefer to attend
on your own check out their website at www.iosoc.com. Registration
is required to attend events, including lectures, scheduled at
the Renaissance Hotel.

LYCASTE, THE BEAUTIFUL SISTER OF HELEN OF TROY By Leo Schordje, LSchordje@dataflo.net, www.schordje.com Lycaste have been a popular orchid since the Victorian era. Lycaste (now Ida) ciliata was the first species discovered in 1798. Lycaste skinneri was described in 1843 and remains the most popular species. There are 35 species in five sections. For horticultural purposes, these can be sorted into two groups based on their growing requirements, evergreen and deciduous. Lycaste breeding and cultivation is in a state that parallels the 1970’s phase of Cattleya hybridization. Hybrids are now into as many as 12 generations, the majority of hybrids are repeated backcrosses of L. skinneri back on to the complex hybrid. General Cultural requirements • Light: Very bright shade to partial sun, about the same light as Cattleya, approx. 2000 to 4000 ftc. Growers can compensate for lower light intensities under artificial light by using 18 hour day and 6 hour nights. • Air movement: This is essential, especially if leaves receive direct sun because air movement keeps the thin leaves from sun burn. • Temperature: Most species are intermediate growers and most will tolerate cool temperatures. Although cool is not required, most species will tolerate summer heat with good air movement. • Potting mix: Any water retentive mix with good air voids will work. Fir bark with Perlite is preferred by many. Use a fine seedling mix for pots less than five inches. • Repot in spring when new growth is one to two inches tall. Repotting out of season can cause problems, but if it is necessary, do repot. Do not allow the mix to get stale. • Water: Keep moist all year round; do not allow it to dry out between waterings. If you keep the plant moist, water quality is not an issue. Never let the mix become bone dry between waterings. This is the way to keep evergreen species like L. skinneri and all Ida species happy. Deciduous species will need a dry rest in LATE winter, usually January and February. Do not start the dry rest too early. Deciduous species need time to mature in fall. • Fertilizer: Lycaste are moderate feeders therefore dilute high nitrogen fertilizer all year round. My personal recommendation is MSU formula at ¼ to ½ teaspoon per gallon, every week. Lycaste dowiana (Endres & Reichenbach) 1874 - Guatemala, Costa Rica, Nicaragua, South America Lycaste leucantha (Klotzsch) 1850 - Costa Rica, Panama Lycaste skinneri (Lindley) 1843 - Guatemala, Mexico, Honduras, El Salvador ------Lycaste skinneri alba ------Lycaste skinneri armeniaca ------Lycaste skinneri Ipala ------Lycaste skinneri rosea Lycaste powellii (Schlechter) 1922 – Panama Lycaste schilleriana (Reichb. f.) 1855 – Panama, Peru, Colombia, Surinam Lycaste virginalis (Scheidweiler) Linden 1888 (correct name is skinneri) Lycaste virginalis alba (Scheidweiler) 1842 (correct name is skinneri alba) Lycaste xytriophora (Linden & Reichenbach) 1872 – Ecuador, Colombia Lycaste macrophylla represents a “super species”, a single widespread species with many geographic variants or a swarm of closely related species. It is a geographically wide spread species, each of the subspecies listed below may be found listed in some references as a species in its own right, or by other authors variously sunk back to variety level or simply geographic races. All variants have big wide leaves, many flowers with wonderful fruity fragrances. Lycaste macrophylla (Poepp. & Endl.) Lindley 1843 Central/South America, Peru Lycaste macrophylla subsp. Desboisiana (Cogniaux) Fowlie 1964 - Costa Rica, Panama Lycaste macrophylla subsp. desboisiana f. alba (Cogniaux) Fowlie 1964 - NC Costa Rica Lycaste macrophylla subsp. filomenoi (Schlechter) Fowlie 1964 - Peru Lycaste macrophylla subsp. macrophylla (Lindley) Fowlie 1964 – Peru Lycaste macrophylla subsp. measuresiana (Williams) Fowlie 1887 - Amazonas Lycaste macrophylla subsp. neglecta (Schlechter) Fowlie - Bolivia Lycaste macrophylla subsp. orinocoensis (Fowlie) 1964 - Colombia Lycaste macrophylla subsp. panamanensis (Fowlie) 1964 - Panama Lycaste macrophylla subsp. plana (Lindley) Fowlie 1964 - Costa Rica, Panama Lycaste macrophylla subsp. puntarenasensis (Fowlie) 1964 - Costa Rica, Panama Lycaste macrophylla subsp. viridescens (Oakeley) 1991 origin? Lycaste macrophylla subsp. xanthocheila (Fowlie) 1964 - Costa Rica The Deciduous Lycaste These species come from areas of Central and South America that experience seasonal wet and dry periods. As a “vague but true” generalization along the Caribbean-Atlantic coast from Florida to Colombia there is a dryer season starting in January, lasting through February, usually ending late March. There is often some rain, but nowhere near as much as there usually is the rest of the year. The Central American Pacific Coast dry season timing is similar. For both areas some local regional exceptions exist that are beyond the scope of this article. The following species are considered deciduous: Lycaste aromatica (Graham ex Hooker) Lindley 1843 - Mexico, Nicaragua, Guatemala Lycaste bradeorum (Schlechter) 1923 - Honduras, Costa Rica, Nicaragua (prefers warmer temperatures) Lycaste campbellii (C. Schweinf.) 1949 - Panama, Colombia (I-W temps) Lycaste cochleata (Lindley) 1850-51 - Mexico, Guatemala (I-W temps) Lycaste consobrina (Reichb. f.) 1852 - Mexico Lycaste crinita (Lindley) 1844 - Mexico Lycaste cruenta (Lindley) Lindley 1843 - Mexico, Guatemala, El Salvador (really prefers intermediate to cool, not very warm tolerant) Lycaste deppei (Lodd.) Lindley 1843 - Mexico, Nicaragua, Guatemala Lycaste deppei var. praestans (L. Linden) 1898 Lycaste deppei var. punctatissima (Reichb. f.) 1881 (possible natural hybrid) Lycaste lasioglossa (Reichb. f.) 1872 - Guatemala Lycaste luminosa (Oakeley) 1991 - Costa Rica (?) Lycaste macrobulbon (Hooker) Lindley 1846 – Colombia (I-W temps) Lycaste brevispatha (Klotzsch) 1851 - Costa Rica, Nicaragua Lycaste candida (Lindley) 1851 - Costa Rica, Nicaragua, Panama Lycaste micheliana (Cogniaux) 1900 = natural hybrid Lycaste saccata (A. Richard) 1848 - Mexico, Guatemala Lycaste suaveolens (Summerhayes) 1931 - El Salvador Lycaste tricolor (Klotzsch) 1852 - Costa Rica, Panama As a general rule the deciduous Lycaste tolerate warm temperatures better than L. skinneri. This means that in all but the hottest areas of the country these species should do fine. For ten months of the year grow these Lycaste as you would the Evergreen species as described above. For one to two months in the late winter give them a dry rest. The best time to start this rest is when all the leaves start turning brown. Stop watering, the mix will dry and the leaves will brown and fall off. This normally will happen late December to the beginning of January. Large specimens in pots 4-inch or larger can simply be left bone dry until new growth is up out of the mix ½ inch or more in Spring. Small plants with small pseudobulbs might benefit being watered once a month or so to prevent excessive shriveling. Some plants may go dormant as early as late November, but it is important to not force dormancy too soon. I have killed a few L. aromatica by forcing dormancy too early, once as early as September. The new pseudobulbs had not matured and the seedlings did not survive. You may encounter the occasional plant that does not seem to want to go dormant. I have an L. cochlearis that still has its leaves in late January and an L. deppei that seldom drops its leaves. If they seem to keep growing, keep watering them. Let the plant tell you what it wants to do. If for some reason a deciduous Lycaste drops its leaves in mid-summer, likely it got too dry between watering or it has root trouble. Check the plant out, spray for pests if needed and keep the plant moist. It should start another growth right away. Again as above, the best time to repot is when new growth is one to two inches tall. The Ida Ida is the third group of Lycaste that are fairly widely grown. They were referred to as the Fimbriata section of Lycaste. Botanically, these are somewhat different from L. skinneri. Eric Christiansen moved the entire Fimbriata group into Ida, out of Lycaste a couple years ago. Most vendors still list them as Lycaste. Taxonomy is in flux so names are certain to change in the future. Ida have a heavier leaf that seems to last four or five years instead of just one or two. They seem to want deeper shade than the others, about the same light level as required for Phalaenopsis is adequate to bloom the Ida group as well. (Around 900 to 2000 ftc.) The Ida generally prefer intermediate temperatures. A few are cool growers and a few are warm growers. All have green and white flowers, many with strong night time fragrances. Some of them have, to be kind, “industrial fragrances,” some are pleasant spice fragrances.
