Living material of Equisetum

[Anthony Pigott]

Dear All

I'm looking for living material of Equisetum of known provenance. If
anyone could help or put me in touch with someone who could, I'd be very
grateful.

I hold the National Collection of Equisetum in the British NCCPG's
National Plant Collection Scheme. I would like to add to it to make it
more comprehensive as a reference collection and also to enable some
work I intend to do on producing comprehensive  / consistent
diagnostics, descriptions and illustrations of the genus worldwide.
(Most accounts, other than Hauke's monographs, only treat them within
one country or at best one continent.)

I'd be interested in almost any taxa from anywhere as I'm trying to get
coverage of the geographical variation but E. laevigatum and its hybrids
are a particular gap at the moment.

I can, of course, reciprocate with material from my collection.

If anyone can help, please e-mail me directly and we can discuss
details.

Regards

Anthony
