dissolving leaf mesophyll

[Catherine DeLong]

Ithink that these are mostly collected from forest floors where 
earthworms have pulled leaves down into their burrows and chewed away 
the soft parts.  I have collected large perfectleaves of maples in 
Michigan in the forest and in Oregon too. They were nicely rolled up in 
their little burrows or just lieing on the forest floor.  It is easier to 
spot the rolled up ones than the flat ones.
