200 White to Green and Brown Flowers 



All the Wormwoods possess a very strong odour, by 

 means of which they may be easily recognized. This species 

 has tiny greenish-yellow flowers growing profusely on its 

 leafy, silky stems, while the whole plant is silvery white and 

 covered with softest down. 



Artemisia discolor, or Green Wormwood, has green foli- 

 age and brownish-green florets, having the same pungent 

 aromatic smell as the silvery species. 



Artemisia biennis, or Biennial Wormwood, has also green 

 foliage, and its numerous greenish florets grow in clusters 

 in the axils, where the leaves join the main flower-stalk. 



PALM-LEAVED COLTSFOOT 



Petasites palmatus. Composite Family 



Stems: scaly, stout. Leaves: orbicular in outline, deeply seven-to- 

 eleven cleft, green and glabrous above, densely white tomentose beneath. 

 Flowers: in a fastigiate panicle. 



The chief distinction between the different species of 

 Coltsfoot lies in the shape of their respective leaves. Those 

 of the Palm-leaf Coltsfoot are exactly like a large palm leaf, 

 while its blossoms are white and very fragrant. The flower- 

 stalks are thick and juicy and covered with small narrow 

 leaves. It has silky-haired seeds like a dandelion. 



Petasites sagittatiis, or Arrow-leaved Coltsfoot, has huge 

 leaves with two very marked pointed lobes at the base. Its 

 flower-heads grow compactly at the top of stout stalks, and 

 are white and fragrant. 



Petasites frigidiis, or Arctic Coltsfoot, has few blossoms, 

 a scaly stem, and very irregularly lobed leaves. The foliage 

 of all the Coltsfoots is green and smooth on the top, and 

 white and woolly underneath. They are coarse uninterest- 

 ing plants.
