SYNGEN. - POLYGAM. ^GlUAL. 231 



It is very difficult to draw the line between this species amd the neigh- 

 bouring one (H. muror.); which may indeed be said of almost 

 every individual in the genus. The present is from 4 or 6 inches, 

 in poor soils, to 2 feet in height. The stem wants the long 

 whitish hairs of the last species and is only closely pubescent 

 at the extremity, where there are sometimes a few black glandular 

 bristles. The involucre has that same short pubescence. The 

 leaves vary wonderfully in breadth and in denticulation as well as 

 in hairiness, though they are always less hairy than those of 

 H. Lawsoni, especially about the petioles. There is one rather 

 large and more or less petiolated leaf on the stalk, rarely one or 

 two small ones above. 



Stem with many leaves, many -flowered. 



8. H. sylvaticum(lVbod Hawkweed),stem many leaved branched 

 upwards and subcorymbose slightly hairy and more or less 

 downy beneath the involucre, leaves ovato-lanceolate or lanceo- 

 late toothed with the sharp teeth pointing upward somewhat 

 hairy, involucre with very short pubescence.

One foot to two feet high, scarcely hairy on the stem, though in the 

 var. /3. found by Mr. Dickson the lower parts of the stem and of 

 the petioles of the leaves have long hairs, whilst that var. (/3.) found 

 by Mr. Don is very nearly glabrous. The leaves are usually nu- 

 merous j yet I have seen some starved vars. which had so few that 

 it was difficult to recognise them as distinct from H. murorum.
