There are a few other species which have been observed by- 

 different botanists in the county, and of which specimens are pre- 

 served in the public herbaria, or which have been mentioned as 

 Hertfordshire plants by some standard authority on British botany, 

 but which are unnoticed in the writings of Messrs. Webb and 

 Coleman. Such are — 



Cuscuta hassiaca, PfeifF. 

 Mentha pubescens, Willd. 

 Amaranthus retroflexus, L. 

 Chenopodium glaucum, L. 



Papaver Lecoqii, Lamot. 



Rubus pygmmis, Weihe. 



Galium approximatum, Gr. & Godr. 



Picris stricta, Jord. 



Xanthium spinosum, L. 



Papaver Lecoqii is not uncommon in the chalky parts of the 

 county. The others are mostly rare and critical forms, or have no 

 claim to be reckoned as natives.
