CEnanthe.] umbellifer^. 205 



1. (E.Jistulosa,lj. Common Water-dropwort. " Root stoloni- 

 ferous, stem-leaves pinnated, their main stalk as well as the stem 

 cylindrical fistulose, umbels of very few rays, fruit turbinate." — 

 Br. Fl. p. 167. E. B. t. 363. 



In ditches, drains, the margins of pools, and in wet meadows, but far from com- 

 mon. Pi. June— Septem1)cv. T^.. 



■ E. Med. — Sparingly in some ditches on the northern boundary of Lake com- 

 mon. In several pans of Sandown level. Brading marshes. Ditches around 

 Sandowii fort, Miss Hadjield .'.'.' 



W. Med. — Marsh-ditches near Freshwater gate. 



Plant of a pale subglaucous green, very fragile, weak and flexile, soon collaps- 

 ing on being gathered, remarkably tubular and fistulose. Stem erect or procum- 

 bent below, sometimes altogether reclining. Fruil crowded into small globose 

 heads, quite sessile, nearly as large as in ffi. crijcata, whitish, mostly purplish 

 brown at top, corky ; syndicarps turbinate or obconic, obtusely and unequally 4- 

 or 5-angled, the faces furrowed and striate ; their summit flat, crowned with the 

 very long spreading or recurved styles and subulate calyx-segments ; hemicarps 

 closely adhering by their inner faces, which are quite plane and smooth, not sepa- 

 rating when ripe as in our other species, their lower end a little sloped away just 

 at the point of insertion on the thickened summit of the ray or common pedicel, 

 exterior to which last, surrounding it, are several abortive fruits on long peduncles 

 ( outer rays of the umbellets) ; carpophore obsolete. 



3. OH. pimpinelloides, L. Parsley Water-dropwort. " Leaflets 

 and segments very acute or mucronate, those of the radical leaves 

 much broader and shorter, fruit cylindrical with an enlarged cal- 

 lous base." — Br. Fl. p. 167. Jacq. Fl. Aust. Icon. iv. t. 394 

 (certe). Fl. Dan. ix. t. 1454. 



13. Leaves all linear, univei-sal involucre none (or imperfect), root often with 

 sessile elliptical tubers. CE. peucedanilolia, Pollich, Fl. Pal. 



In dry or moist but not marshy pastures, on banks, along hedges and roadsides; 

 a very general and often most abundant species. Fl. June — September. Fr. 

 September, October. !(.. 



E. Med. — Plentiful about Eyde, as in Monckton mead, about St. John's, &c. 

 Churchyard of St. Thomas's church, Ryde. About Cowes. 



W. Med. — Frequent in various places about Brixton. In profusion this sea- 

 son (1846) about Yarmouth, Thorley, Calbourne, and most other parts, even grow- 

 ing plentifully in some places amongst the wheat-crops, as at Calbourne, &c. 

 Yarmouth. Freshwater. 



j3. In similar places with a. and also in salt-marshes, but much more rarely. 

 In a wet thicket by the Wootton river. In a meadow near Thorley, and a single 

 large plant growing in the water at Freshwater Gate, only a few plants observed 

 in either locality. Between Yarmouth and Alum bay, Rnv. G. Smith. The ave- 

 nue to Freshwater House produces an (Enanlhe which appears to be this variet;^. 

 Very plentiful, and completely the plant of Pollich, in a meadow under St. John's 

 wood at its upper end, "between it and the brook. 



Plant perfectly smooth and glabrous throughout. Root a bunch of dark brown, 

 rigid, mostly simple fibres, which descend nearly vertically, and usually swell out 

 at various parts of their length, but generally at or near their extremity, into 

 small, ovate, oblong, globose or fusiform, sometimes compressed, whitjsh and 

 fleshy knots or tubers, beyond which the fibre is continued to a finely tapering 

 point : these tubers are produced on seedlings of the first year, and whilst still 

 very young and small, as I have ascertained by cultivation, and are mere enlarge- 

 ments of the amylaceous tissue of the root. Stem 1 or more, erect, from 6 or 8 

 inches to 2 or 3 feet high, slender, wavy, firm, cylindrical, mostly purplish at bot- 

 tom, in my specimens distinctly fistulose ; in the upper part completely tubular,
