4 The Flora of Glamorgan. 



whole may be bound together to form a single volume. The 

 order will be that of the numbers given above — No. i will 

 appear in 1907, and No. 5 in 1911. 



In order to secure uniformity of treatment and the necessary 

 brevity, the records for the separate species will follow definite 

 lines. Following the excellent example set by Watson in his 

 standard works on distribution, each record will, so far as 

 possible, be condensed into a formula. As a rule, three para- 

 graphs, the first two of a line each, will be devoted to each plant — 

 the first for the names, the second for the general distribution, 

 and the last for the detailed distribution and citation of 

 particular habitats. 



The nomenclature presents special difficulties. It is 

 impossible to adhere absolutely to any one system. The 

 Editor is primarily responsible for the names used. In all cases 

 the authority for the name will be cited. The names of the 

 9th edition of the London Catalogue will be adhered to, with 

 certain exceptions rendered necessary by the recent develop- 

 ment of our knowledge of the so-called " critical " species. 

 The numbering of the Catalogue will be quoted throughout, so 

 that a ready means will be furnished for noting the absence of 

 plants from Glamorgan, and of making comparisons with other 

 local Floras. 



The first line therefore devoted to each plant will be 

 occupied by (i) its number in the London Catalogue ; (2) its 

 technical name ; (3) its commonest English name or names ; 

 and (4) its Welsh name or names. Mr. T. H. Thomas has 

 undertaken to supervise the Welsh nomenclature and to 

 furnish, whenever possible, the Glamorgan names. When a 

 special note on names is necessary, it will be added below in 

 smaller print. Mr. Thomas makes the following explanatory 

 note : — 



" The Welsh names appended were taken by Mr. John 

 Storrie, F.L.S., from Richards' " Dictionary," 1751 ; Davies' 

 "Welsh Botanology," 1813 ; " Physygwriaeth yr Hwsmon 

 a'r Tylodion," 1839 ; and " Y Llysieu-Lyfr Teuleuaidd," 1858.
