 and in Peunygill Burn near the Glebe, Hookcria lucens, Sw. 

 Lichens. — In the " Old Statistical Account of Scotland," 

 it is said that " Dundrennan Abbey is almost entirely 

 covered with a pale grey-coloured moss, which gives a 

 character of airy lightness to the lofty columns and Gothic 

 arches,"' — a statement which has been copied into almost 

 all the published descriptions of the Abbey. The moss in 

 question is what is known as Lecidea cancscens, Ach. I am 

 not sure if Dr. Stirton has found another name for it. He 

 wished to do so when I sent him specimens in fruit. It 

 grows in great patches on the wnlls, spreading from soredia, 

 and, wheu old, resem-bles a Physcia more than a Lecidea. 

 Besides this lichen there are — Lecanora aurantiaca, var. 

 incdjnna, Ach. ; L. suhfusca, L. ; Z. subfusca, var. gangaloides, 

 Ach. ; L. jMrella, L. ; L. 2yarell<(, var. ixdlesccns, L. ; L. ven-

 Ach. ; and L. tartarea, L. ; Lecidea sjjcirea, Ach. ; L. alhoatra, 

 var. cpqwlia, Ach. ; L. enteroleuca, Ach. ; Opegrapha saxicola,

Newlaw Loch and Hill. 



Passing along the village we turn to the left at the 

 church into a little glen, and pass westward along the 

 road on the south side of the hill as far as the loch, and 

 then turn northward over the ridge. We note, in passing, 

 that, to the non-botanical eye, there seems to be two kinds 

 of the Male fern — tlie common one with green rachis, and 

 another with the rachis slightly coloured, and densely 

 covered towards the root with yellowish chaffy scales. 

 The Lady fern, Asplenium Filix-fcemina, IJernh., shows also 

 two kinds — one which is locally called the " Black Lady." 

 In it the rachis is brown throughout, and it is altogether a 

 stronger plant. The Moonwort, Botrycliium Lunaria, Sw., 

 grows in abundance on the north side of Newlaw Hill, and 

 also the common Brake, Pleris aquilina, L. (I have found 

 the Moonwort in various places in the parish. I have not
