456 SYNGENESIA— POLYG.-SUPERF. Anthemis. 



in shape from either of the two last genera, though, like them, 

 quite naked ; while on the other hand the calyx is much more 

 flat, not hemispherical. Seeds angular, oblique, quite destitute 

 of any crown or border. 

 M. snaveolens, once reckoned a British plant, has less compound 

 leaves ,- flowers not half so large ; and rather more acute, or li- 

 near, calyx-scales. It grows in the south of Europe only.

Common Cal. hemispherical, closely imbricated, with seve- 

 ral oblong, nearly equal scales. Cor. compound, ra- 

 diant; Jlorets of the convex disk numerous, perfect, tu- 

 bular, with 5 equal spreading segments ; those of the 

 radius numerous, ligulate, spreading, abrupt, generally 

 ■with 3 teeth. Filam. in the tubular florets only, very 

 short, capillary. Anth. in a cylindrical tube. Germ, in 

 all the florets obovate. Style thread-shaped, not promi- 

 nent. Stigmas spreading, oblong, simple or divided. 

 Seed-vessel none but the unaltered calyx. Seed in all the 

 florets obovate, rather compressed, generally with a 

 slight border, or crown. Recept. more or less convex, 

 or conical, beset with lanceolate, acute, chaff'y scales, one 

 to each tubular floret, and generally about the same 

 height. 



Habit much like the last, but with more of an aromatic or 

 bitter flavour. The species are rather numerous; some- 

 what various in their foliage ; natives of Europe and the 

 north of Africa, some of America. Disk yellow. Rays 

 yellow, or white. The scaly receptacle distinguishes An- 

 themis from all the foregoing genera, with some of which 

 it agrees in other respects. 



* Rays isohite. 



I. A. markima. Sea Chamomile. 



Leaves doubly pinnatifid, acute, fleshy, dotted, somewhat 

 hairy. Stem prostrate. Scales of the receptacle promi- 

 nent, sharp-pointed.
