With the exception of the Vanilla genus, orchid seeds lack viable endosperm. Danny Green

Atleast, if you happen to have a problem, the bloke you bought the plants from is not that far away." ROY Well written Roy. If you read the article on page 17 of "Paphiopedilum in Twain 111". You will see that the goverment is highly promoting the industry also. I suppect the the Taiwan nursery was heavily involed in helping the Society meet the publication cost. They should all be very proud of such a high quality product being published. I certinally will be looking forward to buying it. Yes, I think Australian nursery produce top quality orchids also, (BUT it is also a problem guessing what the actual plant looks like when no pictures are avaible of the parent plants.). One of the outstanding catalogues produced last year 2003, was by the the native grower Wayne Turville of Vic. Fantastic amount of colour photographs. If the Australian O/C produced yearly of by-yearly books on say Awarded Paphs/Cymbids/Natives etc. I for one would certinaly be buying them.

The problem is that the smallest ventilator for a greenhouse is 12." The space I have available in the outside wall is only about 4" to 6," the size of a dryer vent. I will have to keep looking.

The theory was further confirmed at Hiroshima. Any generalization about orchid speciation and pollination vectors must consider the dimorphic Catasetums and Cycnoches. After the male flower has implanted its pollinarium on a candidate vector, how does the vector figure out which female flower to seek next to preserve the integrity of a given Catasetum species? Not only does the female flower look entirely different from the male, but most female flowers look alike. Even specialists cannot identify Catasetum species by the form of female flowers. How does the vector do it? Is there some arcane catalog with species keys available only to vectors? Furthermore, once a vector has visited a male flower, what makes it decide that its mission is to next visit a female flower of the same species, lest its labor go for naught and produce such a swarm of hybrids that the integrity of the Catasetum species is destroyed? The Catasetinae are the Rosetta Stone of orchid evolution. I am watching the development of nine Dresslaria pods on two plants, two selfings and seven Dresslaria x Catasetum intergenerics. Wish me luck because artificially propagated Dresslarias have not yet been reported.

Hoyas also have a column. The distinction of orchids is that they have a column and one petal modified into a lip.

I travel to see orchids in the wild quite extensively and for many species almost 70% of inflorescence has at least one capsule. I will agree that there are some species, ie. the Cattleya that seem a bit more reluctant to encapsulate. I was just in Brazil in Minas Gerais and saw hundreds of Laelias with set pods. Almost every Pabstia, Pleurothallis, and Oncidium had a least one pod on its inflorescence. There are many species, especially terrestrails that almost every flower encapsulates, ie Oeoclades maculata and many of the Pleurothallids. Possibly an area that has no encapsulated flowers on any orchids may be missing the required pollenators due to overforesting, pesticide spraying etc. I have seen this more evident in developed nations and in more populated areas more than in wild areas.
