[Plant-education] request for seeds

[Carl Pike]

Does anyone have  a small quantity of seeds of Flaveria - a C3, a C4, 
and an intermediate.  I wish to use them in my undergraduate plant 
physiology course this semester.  For much of the semester, the 
students conduct independent projects of their own design using our 
Licor 6400 instruments.  So in terms of the choice of species, ones 
that have appropriate leaves for Licor measurements would be 
desirable.
