First record: Rand, about 1700; also the first as a British plant. 



Curtis's plate is less happy than usual, but is better than the new 



one in Sy77ie E. B. Petiver's H. B. Cat. ii. 7,+ is a good outline. Two 



forms seem to grow about London ; a dark-green plant with spreading 



branches, and a taller plant with erect branches, and with foliage of a 



brighter green ; but we have not been able to find any good technical 



characters to separate them.

t The spring of St. Agnes le Clere, or Dame Annis de Cleare, was used so lately as the 

 beginning of this century as a bath for rheumatic and nervous complaints ; Bath Street, 

 Shoreditch, marks the site. 



X Babington {Man. vi. 291) refers this figure to R. limosus, Thuill., becauseof the leaves 

 being narrowed at the base. (See also Bot. Gaz. i. 296.) They vary in this respect, and 

 specimens from Parson's Green and Hampstead are so far quite like Petiver's figure.
