Carex seeds

[Nigel Blackstock]

Could anybody help me acquire viable seeds from the following taxa:
Carex flava, C. cryptolepis, any members of the C. viridula complex
and C. lutea, especially C. lutea!

Although seeds from any of the above taxa would be appreciated there
are some taxa or taxa from particular areas that are causing me some
problems in locating.
