The latter concept is at odds with the original concept of
clone. It seems presumptuous for the semantic bandits to have
hijacked a term devised by an extraordinarily astute student
of cultivated plants, someone who had more knowledge of
cultivated plants in his little finger than most everybody
else has in their brains.

No probably to it. From Mathew "The Crocus" (1982), p.94:

"Cytological investigations into 'Golden Yellow' and its 
supposed parents have been made at Kew by C.A. Brighton and C. 
J. Scarlett (1980) and they confirm that it is indeed a sterile 
triploid derived from these two species, wholly maintained by 
vegetative propagation."

[Mathew gives 'Dutch Yellow' and 'Yellow Giant' as synonyms 
for 'Golden Yellow'.]
