I'd be not completely sure about this as a plant most likely to be a
natural hybrid between H. ionasii and another doubtful sp. (I called
this one "spec. 1" for the moment though I know that you hate such
pseudo-names, Jan :-)) occurs on the common Base of Ilu and Tramen
which looks much like a small H. ionasii with short hair, that means
much like H. nutans (I inexcusably call this one H. spec "2" at the
moment :-)).
Spec. "1" looks different for me as the W. Baumgartl-plant however
I'm not 100% sure about this at the moment.

I think best would be a study based on RFLP or other methods which
stronger estimate the genotype rather than the phenotypic expression
to clarify such questions.
