Cym. sanderae and Cym. parishii are a bit of a complicated mess. Cym. sanderae, best-known as Cym. parishii 'Sanderae' and sometimes sold as Cymbidium parishii var. sanderae, is a single, unique clone, demonstrated by Andy Easton of New Horizon Orchids to be a hybrid and not an example of a species (he selfed both the 2N and 4N forms and got considerable variation in the seedlings, often with green blooms). He regards it as a naturally-occurring hybrid of Cym. eburneum and some as-yet unidentified other species and discusses the matter at length in a few posts on the New Horizon Orchid forums (which are reproduced in the book Cymbidium Orchids: Secrets Revealed by Graham & Sue Guest with Andy Easton).

The original Orchid (Cymbidium parishii) is sometimes said to be lost to cultivation. Often it is incorrectly sold as Cym. sanderae. A distinguishing feature is thought to be that these plants typically produce flower spikes from within the leaf axils, whereas the true Cym. sanderae produces both axillary and basal spikes. Cym. sanderae also produces 10-15 blooms per spike, whereas the imposters only produce 3 or 4.

The status of Cym. sanderae itself is also highly debated. The only example used in hybridising is the aforementioned single clone also known as Cym. parishii 'Sanderae'. For a time hybrids were registered as having Cym. parishii as the parent; now, the RHS has changed this to Cym. sanderae (they additionally informed me that up until 2001 parishii and sanderae were not considered distinct). Unfortunately Andy Easton rejects the reclassification and continues to register hybrids made with 'Sanderae' or 'Emma Menninger' as Cym. parishii, rather than Cym. sanderae, which will undoubtedly lead to confusion in future.

The plant known as Cym. parishii 'Emma Menninger' or Cym. sanderae 'Emma Menninger' (see Orchid (Cymbidium sanderae 'Emma Menninger')) is the tetraploid conversion of Cym. parishii 'Sanderae'.
