II. — On some British species of the genus (Enanthe. By 

 John Ball, B.A., M.R.I.A. &c* 



The paper by Mr. Coleman (Annals, xiii. p. 188) has induced me 

 to endeavour to throw light upon some of the doubtful species of 

 (Enanthe. The (E. fluviatilis, Colem., I gathered six years since 

 near Cambridge, and also near Ely, but never having found a 

 flowering specimen was at a loss how to denominate it. It cer- 

 tainly has much the appearance of a distinct species, but I do not 

 think the characters assigned very satisfactory. I find the fruit 

 of the ordinary (E. Phellandrium to vary from elliptical to ovate, 

 assuming quite the form figured in Mr. Coleman's plate; the 

 upper leaf in the figure is also seen in CE. Phellandrium. 



I proceed to describe what I believe to be the true (E. pimpi- 

 nelloides of Linnseus and the continental botanists. This appears 

 to be rare in Britain, as I have only seen specimens, wanting 

 fruit, gathered in a dry meadow upon red marl near Forthamp- 

 ton, Gloucestershire, by Mr. Edwin Lees. I give the description 

 in Latin.
