rized by the presence of Pinguicula vulgarisJParnassia palustris. 

 Geranium sylvaticum, Trollius europaeus, Lysimachia nemorum, 

 Carex dioica, Gymnadenia conopsea, Habenaria bifolia, Hab. viridis, 

 Narthecium ossifragum, Comarum palustre, and more rarely Em- 

 petrum nigrum. All of these plants are extremely abundant 

 about Aberdeen, with the exception of Trollius Europseus and Ha- 

 benaria viridis, which are rare. Empetrum nigrum is abundant, grow- 

 ing upon our moors in a peat soil;, occurring also in gravelly soil, 

 and even growing in pure sand, and in this latter situation binding 

 our sand hills along with Ammophila arundinacea, Carex arenaria, 

 Triticum junceum, Festuca rubra (var. hirta), and others, Mr 

 Watson, at p. 61 of his work, states that the Upland Region is 

 marked by the presence of Arbutus uva-ursi, Vaccinium vitis-Idaea, 

 Polygonum viviparum, Linnsea borealis, Trientalis europsea, Cornus 

 suecica, Corallorhiza innata, Sedum villosum, Oxytropis Uralensis, 

 Galium boreale, and Listera cordata. Of these, in this neighbour- 

 hood, Trientalis europaea, Listera cordata, and perhaps Linneea bore- 

 alis are of most general occurrence, and more plentiful than some of 

 the others; Arbutus uva-ursi, Vaccinium vitis-Idaea, Polygonum vivi- 

 parum, and Galium boreale, are principally confined to a few spots, 

 but there they are abundant. The latter of these is only found on 

 the banks of the Dee, and I believe has not yet been found on Don 

 side. Cornus suecica, Corallorhiza innata, and Oxytropis Uralensis 

 have not as yet been detected in this district. From this short 

 sketch it will be perceived, that (as has been already mentioned) 

 the neighbourhood of A berdeen partakes of the nature both of the 

 northern part of the Region of the Plains, and also of the Upland 

 Region, approaching, however, more to the former than to the latter. 

 The following list of mosses comprehends all which have as yet 

 been found within the distance of ten miles of Aberdeen ; and it 

 may be proper to mention that many localities within that range 

 still remain to be investigated. All of them have been gathered by 

 myself in the places mentioned, with the exception of a ^ew ; in 

 which cases, however, I shall mention the individual who found them.
