It's hard to identify an orchid based on a picture. When I was trying to id mine, I came across a site with lots of Cym. photos, and some resemble yours. http://www.collectorscorner.com.au/O...#37;20Jean.htm
Also, Stephen Early of Australia has a nice site on species and primary hybrid Cymbidiums. On the homepage he says he will help people identify their Cyms. Cymbidium Species - Stephen Early
The grower I emailed thinks it is Cym. Sarah Jean! He drew my attention to the lip shape and how it differs from that of Cym. Nella. Since Sarah Jean is such an old and popular hybrid, I really do think it is this also and am going to label it as that (with the old name on the tag still).
