1 12 A NEW FLOEA OP 



three, as the case may be. After the word "range" we give 

 the climatic zones in which the plant grows, beginning to count 

 from below, so that one denotes the Lower, two the Middle, and 

 three the Upper zone. Then follows, for the plants restricted in 

 the manner which the words are intended to indicate, the adjec- 

 tives Xerophilous or Maritime. 



For an explanation of what is meant by the term Xerophilous 

 we must refer our readers to the postscript to chapter I. The 

 species marked Maritime are those, about fifty in number, which 

 are restricted to the sea-coast. Then follows a paragraph stating 

 in what kinds of situation the plant grows, its frequency and its 

 special localities if it is considered rare enough to make it worth 

 while to enumerate them. It is only for quite the rarer species 

 that the particular stations are stated with any considerable de- 

 tail. In enumerating the localities we always begin with the 

 north and work southward. - "P" means Winch's Mora, and 

 where nothing follows it must be understood that we have no 

 confirmation of the occurrence of the plant as stated since 1831^ 

 and in all such cases it may be held that confirmation has become 

 desirable. "E" means recent collectors, and where it is em- 

 ployed implies that we have confirmation of the occurrence of 

 the plant since 1831. The species marked R, generally but not 

 quite invariably, are those which are mentioned in the reports of 

 the Club as having been gathered upon the excursions. A note 

 of admiration implies that a specimen gathered by the collector 

 whose name is mentioned has been examined and that we endorse 

 the name. The other letters used, T. and B., are the initials of 

 the editors of the Catalogue, and where used imply that we have 

 verified, not only the name of the plant, but also the locality. 

 For the figures which relate to the altitudes attained by various 

 species Mr. Baker is responsible where the name of no one else is 

 mentioned. In connection with this point he desires to express 

 his obligations to Sir Henry James, the Director of the Ordnance 

 Survey. At the time when the information was required none 

 of the contour ordnance maps for the higher portions of the two 

 counties were issued; but Sir Henry James, upon application 

 being made to him, kindly furnished from the survey records a
