Obs. In my Synopsis of the British Flora the number of pollen masses 
is erroneously said to be 2. "Their real number and position were first 
made known to me by Mr. Bauer's drawings; the position in which the 
pollen masses lie, one upon the other instead of side by side, gives them 
the appearance of being 2 instead of four, and caused the error here ad- 
verted to.
