Holotype fragment (botany)

[erast]

   A very interesting new object has been introduced: an isotype not
seen by the author of a new species. What is a part of a holotype
left by a collector to his/her collection and not seen by the author
of a new species? Until now, it has been considered to be an isotype.
Is there any need to differentiate the sometimes different kinds of isotypes,
i.e. different "results of  cuttings"? I hope that NO NEED. The
situation may be described without introducing a new term.
