Tony - I've just written something about this for the AGS website next year. The red Nomocharis was seen by Farrer in Upper Burma, and introduced at least once because Wilkie refers to it growing in one garden, but doesn't specify where. So it does seem as if there is at least a population of this colour, even if there is variation. Cox, in his book 'Plant Hunting in China' also mentions it with reference to Farrer (who he knew and had collected with in similar regions) but climatically this was a difficult area to travel and collect plants. Wilkie describes it as allied to N. meleagrina.
