B. Flammula is a most variable species ; among the forms which 

 occur are — 



Var. LATLFOLius, Wallr. Sched. Crit. 289 ; a luxuriant plant with 

 large leaves and flowers, often mistaken for R. Lingua. It has been 

 seen in Baglcy, Fence Woods, Knowl Hill, &c. 



Var. ovATUs, Pers. Syn. ii. 102 ; a plant with cordate leaves and 

 small flowers has been seen at Bagshot Heath, &c. 



Var. SERRATus, Gaudin, Fl. Helv. iii. 540. R. flammeus serraius, Ger. 

 Em. 962, is not uncommon. 



Var. TENUiFOLius, Wallr. 1. c, is a small creeping variety, sometimes 

 found on the margins of ponds in heathy districts, as near Bracknell. 

 (This name antedates var. pseuclo-reptans, Syme.) It is doubtful whether 

 this is a permanent variety. 



A large-leaved, small-flowered plant, which occurred near Burgh- 

 field and in Fence and Ridge Woods, is rather similar to R. ophio- 

 'Jossifolius, but may be known from it by the absence of tubercles on 

 the carpels. 



R. Flammula occurs in all the bordering counties.

 also been recorded from Gloucestershire, but I am infornaed that it is now
