1862.] BOTANY OF SPAIN. 35 



Narcissus Pseudo-Narcissus, N. biflorus, Beta maritima, Lavatera 

 arborea, Crambe maritima, Vicia lathyroides, Carduus palustris. 

 From the above it appears that exotics have intruded among the 

 native productions of this small^ remote^ insulated rock. 



The principal plant found on the Isle of May is Armeria main- 

 tima, a plant which is used for the ed^^ing to garden-walks ; and 

 those who have only seen in it in this utilitarian state, where it 

 appears flat and tame, but not unprofitable, do not know the bril- 

 liant hues it assumes in this islet, where it grows in the greatest 

 profusion. Its varieties are of all shades of colour, from pure 

 white to the intensest and glossiest shade of pink or carnation. 

 Asplenium marinum ornaments a cave on the south side with its 

 rigid fronds; and here also Artemisia maritima is found in fine 

 condition. To the lovers of lichenology this island will affbrd the 

 greatest gratification. Hei'c the isolated rocks, both large and 

 little, in their lower parts wet and dripping from the incessant 

 surge dashing or rippling against them, are densely clothed on 

 their upper portion with Lichens, which grow in the greatest 

 luxuriance and beauty. 



BOTANY OF SPxVI^. 



A feiv Days' Botanizing in the North-Eastern Provinces of 

 Spain, in April and May, 1860. 



No. IV. Spanish Pyrenees; Andorra. 



A short excursion from the French to the Spanish side of the 

 Pyrenees, about a fortnight after the termination of our tour in 

 Spain, yielded some botanical acquisitions which deserve to be 

 added to the brief records already given of Spanish botany. The 

 interval had been passed in the richest botanical districts of the 

 Eastern Pyrenees, but with results unexpectedly scanty, the 

 backwardness of the season having deprived me of the majority 

 of the plants which I might otherwise have reasonably expected. 

 I hoped that on the southern side of the chain I might have better 

 fortune; nor was I altogether disappointed. 



We crossed the watershed of the Eastern Pyrenees at the head 

 of the long oblique valley of the river Tet, which during the 

 greatest part of its length forms, not a right, but an acute angle
