The "real' stoloniferous T. clusiana
penstemon (Mon, 30 Mar 2015 14:02:31 PDT)

you evidently did not understand what I meant when I wrote " “No such thing
as Tulipa clusiana var. clusiana or Tulipa clusiana f. clusiana exists in
nature.”

According to the Kew monograph, and the Flora of Pakistan, this assertion is
not correct.

"Tulipa clusiana DC. is accepted here in a broader sense as a polymorphic
species. S. Dasgupta and Deb (l.c.) having prepared the scatter diagram,
using various morphological characters, tried to correlate the variation
patterns with the geographical and altitudinal distribution. They came to
the conclusion that five different forms may be recognised. According to the
cytological information provided by Hall (l.c.) diploids, tetraploids and
pentaploids are also involved in this complex, however, as the diploids and
tetraploids are morphologically similar, they are classified together."

Note there is no statement to the effect that Tulipa clusiana DC, as
pictured in Redoute, exists only as a clone. Or is a clone. So the repeated
assertion that this is the case needs to be proved.
