In the breeding of orchids, there are times when a parent comes along that completely and profoundly influences the development of new hybrids, often for generations. For example, Phalaenopsis Doris became the backbone of standard white and pink phalaenopsis breeding, and Paphiopedilum Winston Churchill set the standard for producing fine complex Paphiopedilum hybrids. This is the story of one such parent and how it affected my last 20 years of breeding cattleyas....

 
Angraecum Cucullatum and Its Hybrids
Peter T. Lin
2 pages, 5 images


Angraecum Cucullatum is a little known miniature angraecoid. The species was identified by Thours and published in the Hist. Orchid 48 1822. It is native to the islands of Reunion and Mauritius and is rare in cultivation. The species can be found in the Les Mares Nature Reserve in Mauritius, growing at 500-1000 meters (1620 – 3280 feet) elevation. It has been described as common in humid forests, growing in large colonies on tree trunks and the highest and smallest branches. Flowering can be quite spectacular due to the number of plants on a single branch, with three to four flowers for each plant...

Chikanda: A Tale of Orchids, Aids, and Zambian Bologna

Collecting tubers destroys the whole orchid.
©Mike Bingham

There was a time in Zambia when a bag of dried caterpillars would get you an interview with the tribal chief. Nobody but a destitute widow would think of offering a gift of chikanda. Those days have passed. Dried caterpillars are passé, and everybody wants chikanda, a meatless sausage made from orchid tubers. Today, chikanda is all the rage, an upscale delicacy served in the finest restaurants in the cities. Originally a poor man’s food restricted to a few tribes in Zambia, Malawi and Katanga, today it is a trendy food everywhere in urban Zambia and other southern African countries. The resulting “orchid rush” is wiping out whole orchid populations and is threatening orchid species all over the continent. Wildlife Conservation Society biologist Tim Davenport warns, “At current unsustainable rates of exploitation, many species will be wiped out in a manner of a few years.” So what is this “chikanda?”...

 
Rossioglossum Grande One of the Showiest of Orchids
Roland Schettler
4 pages, 5 photos

In 1839, George Ure Skinner found, near Guatemala City, a plant which first flowered in the collection of the Duke of Bedford in Woburn Abbey in 1841. Odontoglossum grande was described in Bot.
Reg. 26, Misc. P. 47, 1840 by Lindley, and he gave it the name grande because of the really big flowers. Shortly after the first discovery, thousands of plants came to Europe, especially to Great Britain, and died after being grown in hot houses. Normally all Odontoglossum species share as a common feature a lip that starts out closely parallel to the bottom of the column extending outward a short distance where the lip bends sharply to form a more-or-less right-angle with the column. There is a group of six or seven species which do not share this characteristic; the lip being held in the plane of the sepals and petals and generally perpendicular to the column over the entire lip length. Schlechter was the first who pointed out the characteristics of this group and seperated it from Odontoglossum. He gave section the name Rossioglossum. While describing the species Odontoglossum powelii, he put all these plants in subgenus Rossioglossum. The only logical corollary of this seperation was published by Garay and Kennedy as the genus Rossioglossum in 1976 in Orchid Digest 40(4): 142. They published the neccesary new combinations of the species names, one of which was Rossioglossum grande...

Tobia, Colombia: Extreme Orchid Watching
Ruben Sauleda
6 pages, 12 images


One day last June while on vacation in Colombia, we decided to go to a recreational hotel about one hour from Bogota. My wife had put her foot down and told me she did not want to see any more orchids. We had made several trips during the previous days and we had seen too many orchids. The problem is that when I see an orchid growing along the roadside or on a tree overhanging the road, I must stop to take a picture. This means slowing down on curving mountain roads while trying to find a safe place to pull over. After several hundred pictures of orchids in flower, she had enough. We were going to a nice hotel next to a beautiful river to have a relaxing time with good drinks and food...

Microcoelia gilpinae from Madagascar.
©Eric Hunt

Angraecoids are primarily native to Africa and Madagascar, many from very limited areas. Because of habitat destruction, these rare plants have become increasingly threatened. Conservation in situ is very important. Because many of these areas are politically unstable and experience habitat loss due to human development, ex situ cultivation of these orchids may prove to be the only way that some of these species will survive. The Angraecoid Alliance, Inc. is dedicated to conserving angraecoid orchids—both in situ and ex situ. The Alliance is working to make cultural information accessible to orchid growers hoping to increase the success of cultivation of these plants in collections around the world.
There are approximately 700 angraecoid species included in Angraecinae and Aerangidinae which vary greatly in plant and flower size, growth requirements, habitat and distribution...
