| J ADDITIONS TO BREWERS ‘FLORA OF SURREY.' 
(ore, By Henry TRIMEN, Esq. 
Having collected some matter supplementary to that contained in 
Brewer's * Flora of Surrey,’ I publish it in the hope of its’ being of use 
to botanical geographers. The additions are chiefly to the localities, 
though there are a few to the list of species.. I have followed mainly 
the existing Flora in its sequence and nomenclature, and repeated nothing 
already published in it, either in the way- of corroboration or extra 
quotation. I have refrained from giving any localities for those plants 
Which are without them in the Flora (being said to grow “throughout 
the county,” or ‘in all the districts ”), though in some cases T. am in- 
clined: to consider a species so: disposed of, to be of rarer occurrence 
than others to which localities are affixed. . 
Information is partieularly requested in the preface to the work, on 
the geological distribution of Surrey plauts ; the. list, however, given 
in Appendix C (pp. 319—345) seems very complete, as far as my own 
observations on, the matter allow me to judge of it; I have added, 
nevertheless, a considerable number of plants to the Wealden clay of 
the county, which formation seems: to have had less attention paid to 
it, botanically, than the others: Having also had the opportunity of 
botanizing on the Weald of Sussex, close to the boundary of Surrey, I 
have noticed several plants in the former, which have not been recorded 
as growing on the same formation in the latter county ; as the Wealden 
flora is of remarkable uniformity, I have mentioned some ‘of these in 
their places (as found near the Surrey boundary), ín tlie hope of calling 
attention to them, and leading to the probability of their discovery in 
urrey. i 
In addition to-original observations, I have looked through the third 
edition of Ray's * Synopsis,’ Martyn’s * Lists of Surrey Plants,’ and 
Curtis's * Flora Londinensis,’ and extracted all their localities for the 
county.. Many of these have found their way into the Flora through 
the * Botanists’ Guides,’ or * Flora Metropolitana ; those which are 
not entered from such sources I have supplied from the original ones. 
The Dibliological botany of Surrey, however, is left for other hands ; I 
have not attempted to exhaust so large a field. Se
