TRIBE II=— CYNAROCEPHAL^. 



Florets tubular. Juice watery, tonic. 



The plants in this division all bear more or 

 less relation to the common Artichoke (Cynara 

 Scoli/mus). The scales of the involucre are 

 generally fleshy at the base, but terminate out- 

 wardly in a sharp hard point. The florets are 

 tubular, and intermixed with them in the recep- 

 tacle are frequently found the hardened bracts, 

 which in this state are called palese, and which 

 appear to be of a chaffy substance, as exemplified 

 in the choke of the Artichoke, the fleshy recep- 

 tacle being in this plant what we call the Arti- 

 choke bottom. This peculiar formation is 

 shown more in detail in^^. 45, which represents 

 part of the flower of the 

 common Bur or Bur- 

 dock {Arctium Lappa\ 

 so annoying from the 

 strong hold it takes of 

 any part of the dress 

 which it may chance to 

 touch. In Jig. 45 a is 

 the involucre, every scale 

 in which is hooked and 

 turned inwards, so as to hold firmly whatever it 

 may catch ; ^ is a floret showing its tubular 

 shape, and its style proceeding through the
