IIAMULE II? THE N. OY SPAIN. 123 



of the leaves and stem are feathery. As far as I have seen, it is 

 one-flowered, very villous, with one or two very small leaves on 

 the stem. E/Oot-leaves broadly oval, attenuated sometimes rather 

 abruptly into the haft, quite entire. I cannot find a place for it 

 even in the multitudinous species of Grenier. 



The Centaur ea is stemless ; the flowers yellow, two or three toge- 

 ther on the crown of the root. Leaves pinnatifid. It resembles in 

 habit G. mixta, a plant of Grreece and of Asia Minor, but the outer 

 and middle phyllaries terminate in a simple, somewhat dorsal 

 spine without any accessory spines, and the appendage of the 

 inner is narrow, terminating in 3 or 5 small prongs, instead of the 

 broad papery membrane of G. mixta. 



The Stachys is the same as that noticed at Pozazal. 



Another hasty excursion took me from Pozazal to Alar. Before 

 reaching the latter place we leave the limestone and all the 

 supposed appendages of the greensand, and enter a country of 

 gravelly hills. At first the boulders are large and often cemented 

 into rock. As we advance, they are smaller, and with less soli- 

 dity, and beyond Alar the hills gradually sink down into a sandy 

 plain, which extends all the way to Paleiicia, and I believe to Yal- 

 ladolid. In the first part, however, these hills are varied and 

 picturesque, though deficient in wood. They might be visited 

 either on foot or on horseback from Villa Escusa or from Alar, 

 where there is, for Spain, a very good inn. At Alar I gathered 

 Silene conica and S. conoidea. The habit of these is sufficiently 

 distinct to attract attention, and the much greater size of the 

 seeds in >S^. conoidea affords a decisive character. Helianthemum 

 canum, Helianthemwn hirtum, Helianthemum Tuheraria, Doryc- 

 nium fruticosum, Orohus canescens, Scorzonera hirsuta, Evax pyg- 

 mcea, Micropus erectus, Gonvolvulus lineatus, and Thymus striatus, 

 Benth., T. zygis I believe of most authors. 



The botany of the Pyrenees is too well known for me to think 

 of adding to it, unable as I now am to scramble over mountains, 

 and especially as each time I went up into their valleys I became 

 ill. I may, however, make a few remarks for the use of those who,, 

 like myself, are not equal to prolonged exertion. At Pan, a few 

 mountain plants are brought down by the Gave, and find a home 

 on its wide bed of gravel. The valley at Eaux chaudes offers several 

 interesting plants. There is a good carriage-road to Gabas, about 

 six miles above Eaux chaudes. There you are at the foot of the 

 Pic d'Ossau, and a mule-road passes thence into Spain, which,
