First printed record : Babington 1850 (from Borrer's 

 Sussex gathering), but collected more than 100 years 

 earlier by Dillenius, who evidently discriminated it 

 from the other then-known Charophytes. It was not 

 until 1897 that Dillenius's extremely interesting dis- 

 covery was brought to light by Mr. Gr. C. Druce, who 

 published the record in his ' Flora of Berkshire ' 

 p. 623). Mr. Druce in the 'Dillenian Herbaria' quotes 

 the following description, drawn up by Dillenius and 

 attached to the Isleworth specimens preserved in his 

 herbarium : Chara flexilis, ramis et setis trichotomis.
