5. Umbellate Hawkweed. Hieracium umbellatum, Linn. 

 ' (Fig. 598.) 



(Eng. Bot. t. 1771.) 



The perennial stock only forms buds 

 in the autumn, which do not expand into 

 a tuft of spreading leaves, as in the wall 

 H., but in the following year grow out 

 into a leafy, erect, rigid stem, 1 to 3 feet 

 high. Eadical leaves, if any, few and 

 withering away before the time of flower- 

 ing. Stem-leaves from narrow-lanceo- 

 late to oblong, coarsely toothed or 

 nearly entire; the lower ones stalked, 

 and all tapering at the base. Flower- 

 heads rather numerous, on rather short 

 lateral branches towards the summit of 

 the stem, several of which usually (but 

 not always) start from so nearly the 

 same point as to form an irregular umbel, 

 and there are often many others lower 

 down in the axils of the upper leaves. 

 Involucres and peduncles glabrous or 

 shortly downy. Leaves glabrous or hairy underneath ; the stems 

 usually more or less clothed at the base with long loose hairs. Scales 

 of the involucre more regularly imbricated than in the wall H., the 

 outer ones usually spreading at the tips. 



In woods and stony places or banks, throughout Europe and Russian 

 Asia, from the Mediterranean to the Arctic regions. Very common in 

 Britain. Fl. late summer, and autumn.

6. Savoy Hawkweed. Hieracium sabaudum, Linn.

(Eng. Bot. t. 349. H. denticulatum, Eng. Bot. t. 2122. H. boreale, 



Brit. Fl.) 



Although intermediate forms between this species and the last may 

 occasionally be found, yet the two are in most cases easily distinguished. 

 The Savoy II. , though stout and equally tall with the umbellate H., is 

 less rigid and more hairy ; the leaves larger, broader, and more toothed, 

 the upper ones shorter, always rounded at the base, and sometimes 

 almost clasping the stem ; and the flowering branches form a loose
