90 Rev. T. Salwey : List of the scarce Lichens found 



IX. — A List of the scarcer amongst the Lichens which are found 

 in the neighbourhood of Oswestry and Ladlow, with occasional 

 observations upon some of them. By the Rev. T. Salwey*. 



As a study of the Lichens is confessedly one of the greatest 

 difficulties the botanist has to contend with, and as Sowerby's 

 ' English Botany ' and the ' Lichenographia Britannica ' (so far 

 as this last extends), the principal works in our language which 

 give any detailed description of them, are in the hands of few, I 

 have thought that observations upon some of the least common 

 of such Lichens as are found in this part of England may be 

 acceptable to those who are entering upon the study of them. 



Having already made some remarks upon the Welsh Lichens 

 in the 'Annals and Magazine of Nat. History,^ vol. xiii. pp. 25, 

 260, I have enumerated in the present list such only as I have 

 met with out of the Principality, and these more particularly such 

 as are found in the neighbourhood of Oswestry and Ludlow, so 

 that the following may be regarded almost as a list amongst the 

 scarcer of the Lichens of Shropshire, the great majority of the 

 habitats being such as are confined to this county. The de- 

 scriptions of the several species in the ' English Flora ^ are much 

 too concise to enable the student, without occasional help from 

 some experienced botanist, to make them out. Dr. Taylor in the 

 * Flora Hibernica ' has given much more ample details of such as 

 he describes, and has added several new species, some of which 

 are still to be discovered on this side of the Channel, but his work 

 necessarily embraces such only as are found in Ireland. It is 

 much to be regretted that we have as yet no monograph of the 

 Lichens, and till some one competent to undertake so arduous a 

 task shall have supplied this desideratum, any occasional obser- 

 vations upon them may perhaps meet with acceptance at the 

 hands of those who are desirous of studying this branch of botany. 



It is only as a help to such, and not under the presumption 

 that I am capable of throwing much light upon the subject, that 

 I have ventured to send to the Botanical Society of Edinburgh 

 the vfoUowing list of Lichens, with such observations upon some 

 of them as a long acquaintance with, rather than an accurate 

 knowledge of them, has led me to form. If my observations 

 should be the means of removing any difficulties in the way of a 

 single inquirer into this branch of botany, my end will be fully 

 answered.
