Dendrobium sulphureum

In a previous post I described this species which is almost always in bloom, and which like so many of the New Guinea Dendrobiums, has very long-lasting flowers: http://orchidsinbloom-ron.blogspot.com/2010/08/dendrobium-sulphureum-var-sulphureum.html.  The plant now has more flowers than ever and I thought I'd post some new pictures.  As the pictures show, the flowers are produced in pairs and usually stand side-by-side facing opposite directions.
