246 The Flora of Wiltshire. 



July. Area, 1. 2. 3. 4. 5. Distributed throughout all the Districts. 

 The largest of the species, and one of the most poisonous of the 

 umhelliferce. The plant when not in flower is very like celery, 

 " Apiuni graveolens," and the large fleshy tubers of the root have a 

 smell and flavour inclining to that of the parsnep. The root in 

 which the deleterious quality of the plant most powerfully resides, 

 abounds in a yellow-coloured juice which has an acrid unpleasant 

 taste and fetid smell. When grown in a dry situation, this juice 

 disappears, or is secreted in a very small quantity, under which 

 circumstance some botanists regard it as a distinct species, the CE. 

 apii/olia of Sprengel, who seems to doubt whether we possess a 

 plant according with the CE. crocata of Linnaeus.

Eesembling CE. Phellandrium, but differing by the submersed 

 leaflets being divided into finger-like parallel segments, deeply cut 

 at the end, and in the fruit which is broadly elliptical, thrice as long 

 as the spreading styles, Botanists are indebted to the late Rev. 

 H. Coleman for having first directed attention to this plant, which 

 had long been confounded with CE. Phellandrium.
