the end, not much longer than broad*, nearly entire, edged with 

 numerous rigid apiculi. 



I have very little doubt of this being the plant intended by 

 Ray or, rather, Dillenius and Petiver. It is stated in the ' Syn- 

 opsis ' to have been found by Mr. J. Sherard ; but no place is 

 mentioned. Its claims to be an English plant rest upon this 

 very slender authority; and I think that it should not be ad- 

 mitted into our lists at present, although not an unlikely plant 

 to inhabit this country.

Stem 3-4 feet high ; top and usually most of the branches 

 ending in loose irregular corymbs of heads. Heads large, 

 spherical when in flower, but not umbilicate, often hemispherical 

 with fruit, usually quite naked, but sometimes slightly webbed, 

 green or purplish. Radical leaves blunt, as broad as or broader 

 than long, broadest at the insertion of the petiole; petioles 

 quite solid, with prominent angles, deeply furrowed above. 



Possibly Gaertner^s plant was not of this species ; for he 

 quotes Tl. Dan.^ (642). But his figure shows no wool on the 

 head. When he wrote, the species were not distinguished. 



This is the only species which is known to possess solid 

 petioles. 



This seems to be pretty generally distributed, but is not so 

 frequent as A. minus. 



3. A. intermedium (Lange) ; inflorescentia racemoso-pyramidali,

 subsessilibus, squamis involucri flores sequantibus, parte su- 

 periore corollse tubo ejus subsequali campanulata ad basin 



* In measuring the leaves, the basal lobes are omitted in all cases. The 

 base of the leaf is considered to be the point .where the petiole is inserted.
