Hi Jenn,
As far as I can tell Dor. pulcherrima var champorensis
would have been correct... except that pulcherrima (the only species in the Doritis Genus) has been moved to the Phalaenopsis Genus.
The accepted name would therefore
now be Phalaenopsis pulcherrima var champorensis. You can see confirmation of this genus change on the 'World Checlist of Selected Plant Species' on the Kew website.

('kelly' x self) indicates that the 'kelly' cultivar has been crossed with another 'kelly' cultivar. This does NOT result in a 'kelly' because seed crosses even between two of the same cultivar can be genetically different to the parent.
