100 NORTHUMBRIAN BOTANY. [April, 



damaged by the wind, that it never reaches maturity. A little 

 further on, there is a white variety of Digitalis purpurea growing 

 among the rocks ; further on, a patch of Vaccinium Myrtillus. 

 Near the eastern end of the plantation on the south side, where 

 the limestone rises again to the surface, several plants that grow 

 on the crags are found, and with these Briza media and Avena 

 pubescens grow in abundance. Here are also Tragopogon minor, 

 Carex glauca, Anthyllis Vulneraria, Silene infiata, and Linum 

 catharticum. The higher part of the same field is a stronghold 

 of Carduus tenuiflorus. It is not only plentiful, but absolutely 

 a pest, to the great distress of the reaper and haymaker, who are 

 obliged to protect their hands, or experience the truth of the 

 motto which surrounds Scotland's national emblem, Nemo me 

 impune, etc. 



In the same field, but lower down, and beside Ratcheugh 

 (farm), I obtained a few specimens of Crepis setosa, which was 

 introduced with clover-seed. Here are also a few Ferns to be 

 collected: Asplenium Ruta-muraria, on the limestone; A. Tri- 

 chomanes, sparingly, in the crevices of the rocks ; A. Adiantum- 

 nigrum, more plentifully ; and Polypodium vulgare, in great 

 abundance. Lastrea dilatata and Polystichum angulare grow 

 in the plantation. There are a few others I have omitted. The 

 most worthy of notice are Asperula odorata, Scabiosa succisa, 

 Alchemilla vulgaris, Hyacinthus nonscriptus, Lastrea ovata F, 

 Lychnis diurna, L. vespertina, and L. Flos-cuculi, plentiful in 

 the plantation and the drive ; Galium saxatile, on the top of the 

 crags, and Adoxa Moschatellina, at the base; Potentilla reptans, 

 on an earth-capped dike at the south end; and Filago ger- 

 manica, on the dry banks near it."^ 



Lest my description should fail to give the reader a precise 

 idea of the localities of the plants entered, I may remark that 

 the greatest distance between the remotest here mentioned does 

 not exceed half a mile, and even a stranger to the district would 

 succeed in reaping a good reward, or be abundantly repaid, for 

 his visit to this interesting locality. 



* In May, 1858, 1 discovered a small patch of Doronicum plantagineum among 

 the trees in front of tlie crags, but when the trees were cut down, to burn the 

 branches, a fire was made on the place where it grew. I fear the plant is now 

 destroyed.
