Besides the species here described, Ammz majus, a common Continental 
roadside plant, with erect branching stems, finely-cut leaves, a small fruit 
like that of Apium, but with an involucre of a few slender, pinnate bracts, 
like the Carrot, has established itself on the banks of the Severn, near 
Gloucester. [Very lately the Jlk Parsley of northern and middle 
Europe, Selinum caruifolium, Linn., has been found in damp woods in 
north Lincoln and Cambridge, but it is extremely rare and possibly not 
indigenous; it is closely allied to the Lovage, but the leaflets are narrow 
and the seed convex on both surfaces, | 
I. HYDROCOTYLE. HYDROCOTYLE. 
Herbs, mostly aquatic, with leaves often peltate. Flowers in a small 
simple head or umbel, or in 2 or more whorls one above the other. Petals 
ovate, valvate in the bud in the British species, but not in all exotic ones. 
Fruit laterally compressed, the carpels flat, nearly orbicular, placed edge 
to edge, with one prominent rib on each side, and without any prominent 
calycine teeth. : 
A rather large genus, spread over the greater part of the globe, and, 
notwithstanding some rather anomalous South African and Australian 
species, readily known as well by its foliage and inflorescence as by its 
fruit. 
1, H. vulgaris, Linn. (fig. 396). Common Hydrocotyle, Marsh Penny- 
wort, White-rot.—The perennial slender stem creeps along the wet mud, 
or even floats in water, rooting at every node, and emitting from the same 
point small tufts of leaves and flowers. Leaves orbicular, 3 to 1 inch 
diameter, crenate or slightly lobed, and attached by the centre to a rather 
long stalk. Peduncles shorter than the leafstalks, with a single terminal
