The "real' stoloniferous T. clusiana

Jim Waddick's question about what we should call the old stoloniferous clone of Tulipa clusiana opens another can of worms. The plant in question is a clone. Formal botanical nomenclature does not have a rank corresponding to clone (unless you accept Individuum as a formal rank). Ranks such as subspecies, varietas, forma are not suitable because they imply the existence of a sexually reproducing population. No such thing as Tulipa clusiana var. clusiana or Tulipa clusiana f. clusiana exists in nature. What exists in nature and cultivation is a single pentaploid seedling of ancient origin which now forms a multitudinous clone. For my purposes, I call it Tulipa clusiana 'Clusiana'.
