From inspecting the above lists it may be easily imagined that the 

 botanist resident in Surrey is not a little proud of his country. The 

 metropolitan botanist also can certainly boast of a Floi'a perhaps not 

 to be equalled throughout the whole of England. In this district he 

 is particularly rich in orchideous plants. Of the 36 species describ- 

 ed as British, 26 are found dispersed within thirty miles from London. 



In Kent, it may be observed that the species are not quite so abun- 

 dant, in the ratio of 21 to 36, including two species that have not 

 as yet to my knowledge been found in Surrey, at least within the 

 range before specified, viz. * Orphrys fucifera and Orchis tetropho- 

 santhos, 61. These plants are not confined to the counties of Surrey 

 and Kent, in the London district, as might perhaps be supposed ; 

 they also occur in Essex and Middlesex, but not so frequently. To- 

 wards Harefield and St Albans they make their appearance again in. 

 great quantities. We have then in the combined counties of Surrey 

 and Kent, as far as observation has gone, 28 species out of 36 British 

 orchideous plants, the remaining eight being mostly confined to the 

 northern districts. 



Nor is Kent behind her sister county in other rare plants, — Althaea 

 hirsuta, Bupleurum tenuissimum, Hutchinsia petrcea, Valerianella 

 calcitrapa, Hyoscyamus niger, Paris quadrifolia, Gentiana ama- 

 rellay and G. pneumonanthe may be considered but a few of them. 



With regard to the distribution of the whole of the species within 

 thirty miles of London, I have from careful examination and research 

 arrived at the following result :
