The firft leaves rife in fmall tufts; and ufually there are many of thefe form different parts of the fame root. They are oblong, broad, and of a dufky green; and they are once dentated, and that very deeply near the bafe, the reft of their edge being undivided. The ftalks rife among thefe, and are round, firm, upright, and two feet high. Theleaves on them are numerous, andthey are placed irregularly: they are long, narrow, and of a pale green; fharp-pointed, and ferrated at the edges, but not deeply. The flowers ftand at the tops of the ftalks in little tufts, and are large andyellow. The feed-veffels are fhort and roundifh: the feeds are numerous, fmall, and brown. It is common about the fides of ditches, and flowers in Auguft. C. Bauhine calls it Raphanus aquaticus alter, as diftinguifhing it from the preceding ; and moft Geiuwk N fpecies,. di ig only from acciden growth, the one having more water than the other; and ormof the leaves. But this is an error: they differ in: the fhape of the leaves, in the form and difpofition of the roots, and in the bignefs of the flowers. More cannot be required for the diftin&tion of the fpecies in any one from another. Indeed there will happen fome farther accidental variations underparticular circumftances 3 and from thefe fome have eftablithed imaginary fpecies, whichit is fit to reduce to the estan kinds ; though not thofe two to one. Thus, when a part of the firft fpecies is continually under water, thefe leaves which srow from fuch part of the ftalk, will be di vided into fine capillary fegments, in the fame manner as thofe of the vatious-leaved water-crowfoot, which are always immerfed underthe furface. In this ftate the plant has been defcribed by Linnzus in fome of his earlier works, and by Van Royen, Dalibard, and others, under the name of ji/ymbrium, with the lower leaves capillaceous, and the others pinnatifid. In a very dry fituation fome of the upper leaves of the fecond fpecies here defcribed will be deeply ferratedfo.as to appear pinnatifid, In this ftate Vallifnieri has defcribed it as a new fpecies, under the name of / rious leaves ; and Haller under that of/i/ys with the lower leaves oval and ferrated, and the upper ones pinnated. The reducing thefe to their proper fpecies as varieties, for they are evidently nothing more, takes off the imaginary foreign kinds of radicula 3 and they are, by the accuftomed and judicious eye, eafily referred. each to the plant to which it belongs':* but it is purfuing a juft reduction to extravagance anderror, to defire to make two abfolutely:different fpecies pafs for one, becaufe each has its varieties, which may be referred to it, ‘This is one of the inftances of that common mif- take, the not knowing where to ftop.
