Hi Lee & All, I can only find 2 references to Brs. arachnoidea. The first is by Norris Williams Thesis in 1972 were he puts it under Sec. heading "Obscure & Excluded Species. Known only from the type description and drawing in Mart. Fl. Bras. iii. V1. 97 {1904 1906} Eric Christenson's answer to the same question I had was a photo copy of the type species of Reichenbach's description of the plant in Vienna . He also mentioned that there was a copy in the Nat. Col. Orch. 1:53. #37. It seem to have a different callus to most of the Brs.been closed at the front and a semi circle at the back. I included his quote. "All we have are the original drawings and text. There are no known actual specimens preserved by Barbosa Rodrigues. Fortunately his drawings/watercolors were done life-size so measurements are available. So, from Cogniaux's treatment in Flora Brasiliensis: arachnoidea - pseudobulbs 10-11 x 3-3.5 cm; leaves 20-25 x 5-5.5 cm; inflorescences 40 cm long; dorsal sepal 4-5 cm long; lateral sepals 6-7 cm long; petals 3.5-4.5 cm long; lip 3.5-4 x 1.5 cm."
I do have a CD on Brassias/Ada that covers about 90% of the known Species. All of the plants are grown and Photographed by me. It is not intended to be a scientific paper but 1 persons struggle over the past 20+ years trying to find information. It is an interactive Cd were you control were you wont to go. There is a index to find the species you are looking for and section culture. Cost CN$30.00 or US$ pluss S & H. Jerry on Vancouver Island were it is cold and grey. _______________________________________________ the OrchidGuide Digest (OGD) orchids@orchidguide.com http://orchidguide.com/mailman/listinfo/orchids_orchidguide.com
