leaves, folding over each other, like the tiles of a house, each 

 furnished with a hook at the end. Thus the whole head of 

 seeds is surrounded with hooks, and these not only preserve 

 them from being eaten, but by their clinging to any thing 

 rough which touches them, such as the skins of cattle, they 

 are conveyed, and the plant thereby dispersed, to a distance. 

 Children pluck these burrs, and stick them on each other's 

 clothes for amusement. 



TANSEY. TANACETUM. 

 COMMON TANSEY. Tanacetum vulgare. 



Plate 12, fig. 14. 



An upright plant, growing two or three feet high, with 

 exceedingly beautiful, much-divided, dark green leaves, and flat 

 heads of numerous, small, bright yellow, autumnal flowers. 

 Often cultivated in gardens, and found wild in the borders 

 of fields and on road-sides. In medicine it is valuable for its 

 fine bitter flavor, and strengthening properties ; and though 

 the taste is disagreeable to most persons, yet the young leaves 

 are often used by country people to flavor puddings, &c. 



WORMWOOD, &c. ARTEMISIA. 

 SEA WORMWOOD. Artemisia maritima. 



Plate 12, fig. 15. 

 Leaves white on both sides. 



On the sea-shore, and on river-banks, as far as the salt 

 water flows over them, is frequently to be seen a plant, every 

 part of which is downy and of a perfectly white color, this is 

 the Sea Wormwood. Besides this it may be known by the 

 various stems (sometimes quite upright and sometimes drooping 

 at the top) being thickly covered with leaves on all sides. 

 These leaves are cut into very narrow divisions and twice com- 

 pound. The -flowers are very small and insignificant, borne 

 all along the upper part of the numerous branches. The whole 

 plant is very bitter in taste. 



COMMON WORMWOOD. Artemisia absinthium. 



Plate 12, fig. 16. 

 Leaves dark green above, white underneath. Flowers yellow.
