This article was passed on to me. I thought I would post it for you. It is
the March 2008 issue of Neodiversity. The article continues the work of
Chiron Castro, but uses three instead of one molecular data sets. The
conclusions are opposite to the previous. Laelia and Sophronitis should be
My question to Ned Nash is this; Why then has the AOS been so
strongly supporting the promotion of the mass produced - low prioduction
cost - potted plant market at the detriment of the small, custom

I am enjoying this exchange. This re-alignment of Laelia seems to
