Monsters, you have just made me order the Kew monograph. I had previously been subsisting on various papers and Tulips, Species and Hybrids for the 
Gardener, a generalist survey by Richard Wilford, who is at Kew, knows a lot about a lot of bulbs, contributed the cultivation chapter to the monograph and is a fine fellow.

>> I don't have a copy of the Kew monograph to check, but I'll bet that the concept of Tulipa clusiana presented there is the same concept of that species which has existed since DC named the species. But the contemporary concept is different, although you might never guess it from the way that concept is sometimes expressed in the nomenclature.
> The contemporary (insofar as the publication date of the monograph, 2013, can be considered contemporary) concept is the same as DC’s concept. It has not changed. Tulipa clusiana DC is and always has been T. clusiana DC. First flowered in 1607. Illustration by Redoute: http://plantgenera.org/illustration.php/…
> Tulipa clusiana DC, syn. T. stellata Hook., pentaploid. Red and white flowers. Narrow upright leaves, as with the rest that follow. 
> T. clusiana forma cashmeriana (A.D. hall) Raamsd, syn. T. aitchisonii subsp. cashmeriana A.D. Hall, “primrose yellow” flowers, diploid.
> T. clusiana forma diniae Raamsd., syn. T. clusiana var. chrysantha A.D. Hall, T. stellata chrysantha A.D. Hall and also Hook., red and yellow flowers, tetraploid.
