196 NORTHUMBERLAND BOTANY. \July, 



and Arum maculatum are plentiful. Neither of the two latter 

 mentioned have ever been branded as foreigners in England. 



On the abbey walls Euphorbia Esula is plentiful, associated 

 with a genuine native, viz. Polypodium vulgare. Most botanists 

 presume that the Euphorbia is an escape from the garden of the 

 Carmelite friars ; but if so, it is pretty well naturalized by this 

 time^ for the holy brotherhood was dispersed and their establish- 

 ment dissolved in the reign of Henry VIII., now more than three 

 centuries ago. 



The other mural plants growing on these ruins are as follow, 

 viz. : — Cheiranthus Cheiri, Echium vulgare, Valeriana rubra, 

 Parietaria officinalis, Pyrelhrum Parthenium, Arabis hirsuta, 

 Cardamine sylvatica, C. hirsuta, Vinca major, Linaria Cymba- 

 laria, Asplenium Trichomanes, Lithospermum officinale, Cheli- 

 donium majus, Hieracium sylvatica, Draba verna, Sedum acre, 

 Linaria vulgaris, Arenaria trinervis, etc. [We wish our cor- 

 respondent would look for Arenaria balearica, which as yet has 

 been observed only in two localities in the British Isles, viz. in 

 the counties of Perth and in Wilts : see ' Phytologist ' for April, 

 1861, p. 127.] 



Brizlee Hill is literally, or rather, botanically, covered with 

 Trientalis europaea ; and in the leafy month of Juue, it is a spot 

 well worth visiting ; for such a profusion of these fine plants in 

 bloom, as is afforded in this locality, is a sight of not very fre- 

 quent occurrence. Vaccinium Vitis-idaa and Empetrum nigrum, 

 Pyrola minor, Juniperus communis, etc., abound on the said ele- 

 vation. 



Ferns are plentiful in the woods, and in various parts of the 

 park, though none of them are of great rarity. The most in- 

 teresting species are Polypodium Phegopteris, P. Dryopteris, at 

 the base of the hill ; on the north side, Lastrea Oreopteris, L. 

 dilatata, and L. Filix-mas are abundant. Athyrium Filix-foemina 

 occurs everywhere in some one or other of its varied and beauti- 

 ful forms. Scolopendrium vulgare grows on a wall near Hulne 

 Abbey. Polystichum aculeatum grows in Blackbog Dean, and 

 Pteris aquilina and Blechnum boreale all over the woods. 



A few plants of Lastrea Filix-mas, var. incisa, are occasionally 

 to be observed. 



Rugley Wood, about two miles from Alnwick, produces the 

 following rarities, viz. : — Gagea lutea by the burnside, but not in
