caulis, which appeared to be very scarce in this locality, as 

 no other specimen was noticed by any other individual. 



Passing beneath the archway of the railroad, (the railroad 

 dividing the common into two parts), and turning a short dis- 

 tance to the left, on the borders of small water-courses Ly- 

 copodium clavatum and Lye. Selago are to be sparingly found ; 

 the latter species being exceedingly unfrequent in the neigh- 

 bourhood of London, never having before met with it. It 

 would be as well to state that it was not in fructification, while 

 the other species, Lye. clavatum, was in excellent condition. 

 I do not see any reason why Lycopodium inundatum, which 

 is so plentiful on Wimbledon and other commons around 

 London, should not be found on Woking Common, as the 

 subsoil and situation are very similar. 



In the opposite direction, towards the small wooden bridge 

 that crosses the canal, a large sandy plot of ground will be 

 observed, abounding in Littorella lacustris, Hypericum elo- 

 des, Anagallis tenella, Helosciadium inundatum, Carex stel- 

 lulata, C. jlava, C. (Ederi, Juncus uliginosus var, bulbosus, 

 Juncus bufonius, Eleocharis palustris and caspitosa, Ranun- 

 culus Flammula var. reptans, and Scirpus fluitans. In dry 

 sandy ground Blechnum boreale. On the slopes of the canal 

 near the wooden bridge, Ervum hirsutum, and the variety <3 

 of Luzula campestris, called Luz. congesta, from the flowers 

 being capitate, and the capitidi being collected into an orbi- 

 cular sessile head. This is the Luciola congesta of ' English 

 Botany,' plate 2718. In the canal Myriophyllum spicatum, 

 Ranunculus aquatilis and Potamogeton densum were observ- 

 ed. I have no doubt that in the months of July and August 

 this locality offers an extensive field for the practical botanist. 



I must not however leave this locality without noticing a 

 variety of the Calluna vulgaris altogether new to me, although 

 mentioned by the older writers to occur occasionally on the 

 heaths and commons in various parts of the country: — I al- 

 lude to the & Erica vulgaris of Gerarde, 1380, and mentioned 

 in Ray's ' Synopsis Stirpium Britannicarum,' p. 471, as fol- 

 lows. —
