 rough or hairy subcoryiiibose at the top, leaves ovate-lanceolate 

 or lanceolate toothed, lower ones narrowed into a petiole, upper 

 sessile with a broad rounded or cordate base, peduncles with 

 copious white stellate down scaly, involucres ovate at the base 

 uniformly blackish-green when dry, scales appressed sometimes 

 hispid on the keel and sprinkled with longish white hairs other- 

 wise glabrous and free of black seta?, innermost ones very blunt

 (blackish-brown or red) slightly scabrous. H. Sabandum E. B.

 this is a much more variable plant than is generally supposed : that 

 which is usually so called is as above characterised, and is best known 

 by the dark green blunt scaled involucres without down contrasting 

 with the white downy peduncles.^

Pappus neither filiform nor plumose, (Gen. 14, 15.) 



14. Lapsana Linn. Xipple-wort. 



Achenes compressed, striate. Pappus none, or a mere

 scales, with small ones at the base. — jSTamed from XaTra^w, to

' In the above account of the genus Hieracfum, we have endeavoured, aided 

 by notes and specimens from Messrs. Baker and Backhouse, to give short des- 

 criptions (rather than specific ciiaracters) of almost all the /(5n;i5 enumerated as 

 British, and have even admitted a few of which we have no specimens. Fries 

 inentions several more, and we have seen many specimens of an intermediate 

 kind that can be referred to some one or other onlv with doubt, indicating that 

 unions require to be made. At present, however, we are quite ignorant how these 

 lorms are to be combined so as to constitute species with &ome positive or absolute 

 and well-defined character, by which they can be readily recognised in the field or 

 in the garden, alive or in the herbarium, stunted or drawn out, with certainty and 

 precision : in a difficult penus, negative or comparative characters are of no use 



except to those who alreadv know most of the species. Mr. Backhouse, of York, 

 IS, \ve understand, enf:aged in studying this genus, and will, w 



public the result of his labours.
