 pressed from the sides, and for the most part contracted and 

 didymous ; mericarps with 5 filiform ribs, which are at length 

 a little winged : lateral ribs marginal ; all equal. Seed terete or 

 gibbously convex, flattish in front, or terete in every part. Um-

LIN. SYST. Pent&ndria, Digynia. Margin of calyx 5-toothed. 

 Petals oblong, ovate, entire, spreading, having an indexed or 

 involute point. FVuit roundish or ovate, didymous, plicately 

 wrinkled ; mericarps solid, with 5 thick, very blunt, circularly 

 plicate ribs, covering the furrows ; each furrow furnished with 

 a vitta, and ornamented with plicate tubercles. Carpophore bi- 

 partite. Seed gibbously convex, flat in front. Perennial smooth 

 herbs, natives of the Levant. Leaves decompound. Umbels 

 nrfhnerous. Universal involucrum wanting or few-leaved ; invo- 

 fScels 3-8-leaved. Flowers yellow, dioecious, or polygamous. 

 This genus differs from Cachrys in the seed not being involute 

 nor free, but straight, and adnate to the calyx. It differs from 

 Seseli in the form of the petals and sunk ribs of the fruit, and 

 from Hippomarathrum in the seeds being flattish in front, not 

 with involute margins.

 this or to the preceding species.

 and they are easily increased by seeds.

 roundish, contracted from the sides, didymous ; mericarps with

 in whorled fascicles ; leaves triternate ; segments lanceolate, 

 serrated ; umbels opposite the leaves and terminal. Tf.. W. H. 

 Native of the north of Europe, from Lapland to Germany ; and 

 of Siberia in ditches, lakes, rivers ; North America between lat. 

 54 and 64. In England it is not common, but is found at 

 Isleworth, in the Coin, near Colnbrook, and Uxbridge ; on 

 Hounslow Heath ; in the Isle of Ely ; Lovingland, in Suffolk ; 

 near Norwich and Yarmouth, &c. In Scotland it is more com- 

 mon, as in the Lake of Forfar, and other lakes in Strathmore,

 Towards the end of autumn the root for the succeeding summer 

 is formed out of the lower part of the stalk ; this is divided 

 transversely into many large unequal cells, so that it becomes 

 specifically lighter than water, and in winter, when the rivers or 

 pools swell, is buoyed up. The old root then rots, floats all 

 the winter, and in rivers is frequently carried to great distances, 

 In the spring the old root is washed away, and the new one, on 

 coming near the soil, sends out many slender fibres, by which 

 it is again fixed, grows, and flowers. Watson, in phil. trans. 

 It is one of the rankest of our vegetable poisons. Numerous 

 instances are recorded of its fatality to the human species by 

 Wepfer, Haller, and others, and in the phil. trans, by Dr. Wat- 

 son. Linnaeus relates its fatal effects on kine ; and Dr. Wither- 

 ing relates that early in the spring cows often eat it, and are 

 killed by it, but as the summer advances, and its scent becomes
