CHICORY 201 



The stem is often 3 ft. high. The flowers are tall, blooming in 

 July up to September. Chicory is a herbaceous perennial plant, pro- 

 pagated by division, coming up yearly in the same place, and worthy of 

 cultivation. 



In dull weather the 

 flowerheads are closed, as 

 at night also, but in the 

 sun they expand 30 mm. 

 The tube is 3 mm., and the 

 limb 13 mm. long, and by 

 this means it is rendered 

 conspicuous in spite of the 

 few flowers. The flowers 

 are similar in plan to those 

 of the Dandelion and 

 Hawkweeds, but the 

 branches of the style are 

 more curved, making two 

 spiral turns. If insects do 

 not visit it, it pollinates 

 itself. The honey bee, 

 Andrena, Halictus, Osniia, 

 Diptera, Syrphidae, Syritta 

 pipiens, Eristalis tenax, 

 Lepidoptera, the Clouded 

 Yellow Butterfly (Colias 

 edusd), and a beetle, Ma- 

 lachius bipustnlatus, visit it. 



The pappus of the 

 crown of minute, erect, 

 blunt scales assists in dis- 

 persing the achenes by 

 the wind. 



Wherever it is found 

 the requirements of Chicory 

 are sand soil, as it is prac- 

 tically a sand-loving plant growing on sand soil or gravel, as well as 

 on chalky soils or Oolite, where it may at least be native. 



A fungus causing Chicory disease, Pleospora albicans, attacks it, as 

 well as Puccinia hieracii.
