Not a big Aroid enthusiast other than Zamioculcas zamiifolia and a few others. I'm primarily interested in succulents and bulbs. That article about "Epiphyllums" on the CSSA website is a bit out-of-date and has several glaring errors. The list of allied genera is all mixed up too. Not a big fan on anecdotal reviews of plant genera. Common knowledge is usually wrong. I wonder just who are the qualified experts. Regretably, there still remains the same disparity between horticultural enthusiasts and botanical accuracy in most plant groups as there did during the days when Liberty Hyde Bailey was still alive.
