Pod Parent Plant
Culture Notes from Donor: Parent plant: Temperature range I (60-83°F). Oncidium edwallii requires bright light as most oncidiums do, and excellent drainage. It does very well mounted on bark with a small spaghnum pad, and put it under the Vandas. Up close to lights would work too. I checked that it is an intermediate grower but it can also take it quite warm as well.
Comments: Parent plant: The very small yellow, white and light brown flowers are produced on a 12-18 inch arching inflorescence. The plant is very small but probably bigger than a miniature.

Flask Information
Availability: We have sold all of the flasks for this item.
You should: Consider getting individual plants or compots instead of a flask.
You can place a "Notify Flask Recipients" Request, and either we or a flask recipient may contact you when plants are available.

You may also place a "Notify Retries" Request, and if an identical pollination (the same parents) is done again, we'll let you know.

You may reserve a flask, but it's very unlikely you'll get one ...this could only happen if we found a flask that we didn't know we had.
Yield Estimate: 444 plants (based on flask surveys done 04/15/2010 through 06/15/2011)
Yield estimates are only approximate, but may appear to be fairly exact numbers because they are a combination of large rough estimates in remaining mother flasks and more accurate small estimates in reflasks.
Plantlet Sizes: From many flasks 0.2 - 75 mm plants (based on flask surveys done 04/15/2010 through 01/03/2012)
From one most recently surveyed flask 20 - 70 mm (01/03/2012)

The origin/habitat information below is supplied courtesy of Charles and Margaret Baker

The following information is based on the name of the plant provided by the donor, and assumes that the name is correct. If the plant has been misidentified, then the following information may not be correct.
This text is copyrighted by the Bakers and may not be reproduced without permission.

ORIGIN/HABITAT: Brazil. This orchid was discovered originally in the Serra do Mar in the state of São Paulo. Pabst and Dungs (1975) reported that it is now known to occur in the states of Minas Gerais, Espírito Santo, Rio de Janeiro, São Paulo, Paraná, Santa Catarina, and Rio Grande do Sul. Plants grow in the hot, humid lowlands along the coast, in marshy areas of the interior, in the cool, moist mountains near the coast, and in colder regions with rigorous winters. Tomlinson undated (1986?), however, reported that these plants require cool, moist conditions. We have estimated the habitat elevation to provide these conditions, but growers should use the resulting climate table and cultural suggestions with caution.
