on the genus Trifolium

[Servando Carvajal]

Dear Taxacomers:
        One of my students is interested in writing a monograph of the genus
Trifolium and related genera of Mexico. Can anyone inform me if there is
someone who is working now with Trifolium, and how we might contact them?
Does anybody know how can we get a copy of the next references?
