BOTANICAL SOCIETY OF LONDON. 



August \st, 1845. — John Reynolds, Esq., Treasurer, in the chair. 



Mr. F. Barham exhibited specimens of CEnanthe fistulosa ( L.)^ 

 collected by him in Battersea Fields, Surrey. They were growing 

 in water, on a very moist spot, and on })asture of the usual character. 

 Mr. B. observed the roots of the plants in water to be of a fibrous 

 nature, in the moist soil somewhat stoloniferous, and in some more 

 dry situations, tuberous, of the fusiform character. One plant that 

 grew on the spongy soil at the edge of the water, and had fibrous 

 roots, possessed also large decaying tubers of last year, the result, 

 Mr. B. imagined, of the very dry summer.
