Hi all sorry for my long absence (combo of work and family commitments) - then again, I am sure you haven't missed me!
Anyway, with regard to the articles: >From: "Alan W Stephenson" <[EMAIL PROTECTED]> >Subject: [OGD] Conservation Alan S - well done with broadcasting those decisions in Aus about the Mt Rae and Jandakot decisions. >From: various >Subject: Re: [OGD] Catasetums? /upward growing roots >... to draw attention to the same trait in Ansellia (Africa) some Cymbidium (chiefly mainland Asia) and Grammatophyllum (Pacific Asian)... The trait is also known in some unrelated groups, including some of the dendrobium species in eastern Australia (D. rex - syn. D. speciosum var. hillii - among others), and I have also seen it in Oncidium species in my collection. There is obviously some advantage to the habit for it to have appeared several times in distantly related groups - I would assume lying in the combination of poor nutrient levels and relatively high humidity in the epiphytic habit and the need to capture other sources of nutrients in the form of litter fall.
