XXXII. HYFOCHCERE. HYPOCHCERIS. 



Annuals or perennials, with the habit and pappus of Hawhbit, but 

 more frequently branched ; the involucres rather more imbricated, and 

 there are a few chaffy scales on the receptacle between the florets, at 

 least amongst the inner ones. 



More numerous in species than Hawlcbit, it has also a wider geo- 

 graphical range, extending over Europe, Russian Asia, North America, 

 and western and southern South America. 



Involucres oblong, nearly glabrous. 



Florets scarcely longer than the involucres. Outer 



achenes without a beak 1. Glabrous H. 



Florets longer than the involucres. Ail the achenes 



ending in a slender beak 2. Long-rooted H. 



Involucres large, hemispherical, and hairy 3. Spotted H.

Much resembles the long-rooted H., 

 but is a smaller plant, with an annual 

 root, and quite glabrous ; the stems sel- 

 dom attain a foot in height, with much 

 smaller flower-heads, although the in- 

 volucres become much elongated after 

 flowering. The achenes are similarly 

 wrinkled, and have the same feathery 

 pappus, which however is sessile on the 

 achenes of the outer florets, whilst on 

 the central ones it is supported on a 

 slender beak, as in the long-rooted IT. 



Although generally spread over cen- 

 tral and southern Europe, and natu- 

 ralized even in distant temperate cli- 

 mates, it is much less common than the 

 long-rooted H., growing chiefly in sandy 

 situations. Thinly scattered over Eng- 

 land, the Scottish stations are still 

 fewer, and not recorded from Ireland.
