Taraxacum L. Compositae (13). 25 temp. T. officinale Weber (dan- 

 delion), almost cosmop. The thick primary root is perenn. and 

 crowned by a very short sympodial stem ; each year a new bud is 

 formed on the leafy axis, to come into active growth in the following 

 year. The roots as they grow to maturity contract and thus drag the 

 stem downwards so that it never rises much above the soil. If the 

 root be cut through, a callus forms over the wound, and from this adv. 

 shoots develop. The 0. rnech., &c. are of the usu. type of the fam., 

 and show the final autogamy very clearly.

 (cf. Sonneratia).
