PROCEEDINGS OF THE 
Flora.’ Dr. Hooker, however, in his e British Flora,’ 3rd 
ed., p. 181, mentions var. j3, Smith, as being hairy , and states 
that it is the Erica ciliaris of Hudson, not of Linnmus. This 
extreme degree of hairiness is, I think, a sufficient character 
to warrant its introduction into the other British Floras, as 
the Calluna vulgaris, var. (3, hirsuta, (Gerarde). 
Proceeding by the carriage-road to Guildford, Littorella 
lacustris was also observed on the right, in low marshy spots 
by the wayside, near to the village of Stoke ; together with 
Huttonia palusti'is, in a ditch by the road. Between, Stoke 
and Merrow, shortly after leaving the former place, on the 
left is a barren piece of land, upon which was found Trigo- 
nella ornithopodioides ; and on the right, a large marshy plot 
of ground, covered to the extent of two acres or more with 
Littorella lacust?’is, both in and out of the water. 
Taking the path to the left, which leads to a large park, 
through which passes the river Wey, Cardaniine hirsuta, 
Ervum hirsutum, and Erv. tetraspermum were observed. — In 
the meadows, one specimen of Orchis Morio was found, with 
delicate fawn-coloured flowers, a state in which I had never 
before observed that plant. There were numerous specimens 
in the ordinary state, but only one with the fawn-coloured 
flowers. I cannot find this variety mentioned in any of our 
British Floras ; I therefore conclude that it is exceedingly 
rare, as it would undoubtedly be recorded, if it were only for 
its extremely delicate colour. Numbers of the Orchis mas- 
cula were also found interspersed with it, as was also a white 
variety of Ajuga reptans. 
The only remaining plant to be noticed is the Hyoscyamus 
niger, three specimens of which were found nearer to Guild- 
ford.

During a short visit at Brentwood, Essex, I was solicited 
by Mr. Breese, of the Nursery of that place, to inspect a 
fence he had constructed, which was termed by him a
