triangular-subulate calyx-teeth ; the exterior fruits on pedicels as 

 long as themselves. Plant bright-green, glabrous. 



There are two forms of fruit in this species, apparently depend- 

 ing (as in (E. crocata) upon the greater or less development of the 

 lateral masses of corky tissue. 



Fine-leaved JFa ter-Dropwort. 



French, (Enanthe Phillandre. German, Fenchelsamige Pferdesaat. 



Linnaeus informs us that the horses in Sweden are seized with a kind of palsy 

 on eating this plant : hence Withering and Sibthorp have named it horse-bane. It is 

 common in ditches and streams in England, and was at one time used medicinally. It 

 is said to have been useful in asthmas, phthisis, and intermittent fevers, and has also 

 been administered in cases of cancer and ulcers. The fruit causes giddiness when 

 swallowed ; and other symptoms of narcotic irritant poisoning have followed the use 

 of the herb, even in small quantities.

Plate DXCIX. 



Stem decumbent, floating, the flowering portion only rising out 

 of the water. Submerged leaves bipinnate, with the segments wedge- 

 shaped or narrowly rhomboidal, translucent, cut at the apex into 

 linear acute parallel segments. Leaves out of the water bipinnate 

 or pinnate, with the leaflets not divaricate, narrowly rhomboidal, 

 pinnatifid ; segments subacute. Cremocarp oblong - cylindrical, 

 without a callous ring at the base. Styles about one-third the 

 length of the cremocarp. 



In running water. Not uncommon in the South-East of 

 England; occurring in Somerset, Dorset, Hants, Kent, Surrey, 

 Essex, Middlesex, Bucks, Cambridge, Oxford, Leicester, Hertford, 

 and probably in several of the adjacent counties. 



England. Biennial (?) or Perennial. Autumn. 



Stem elongated, flexible, with numerous root-fibres, producing 

 submerged leaves wdth leaflets f to 1^ inch long, cut into parallel 

 segments, deejD-green and without epidermis. The part of the 

 stem which flowers rises out of the water ; the leaves and flowers 

 are extremely like those of (E. Phellandrium, except that the leaves 

 are less finely divided and have the leaflets and segments not 

 divaricate. The rays of the umbel are usually longer and stouter ; 

 the fruit generally longer, about J inch long, and narrower in pro- 

 portion, deeper in colour. 



It must be borne in mind that the diflerences between this 

 plant and (E. Phellandrium are such as might be produced by the 

 circumstances under which they have grown ; so that until we have
