mid the Pyreneesy in 1825. 271 



skirted along the north side of the hill towards the west, until 

 we arrived at a wood, in which we expected to procure the Pcb- 

 onia perefftina. A fortnight ago it had been in bud ; but in bud 

 it still was, and we were consequently disappointed. We had, 

 however, another object more worthy of search ; and we now be- 

 gan to make inquiries after a place called La Roque, or Roquette. 

 No one of the few we encountered could, however, give us that 

 information. At last we met one who told us that there was a vil- 

 lage called La Roque some leagues to the north : of that we were 

 aware, but it could not be our La Roque. The plant we sought 

 for was the Brassica humilis, a plant closely allied to B. i-epanda^ 

 the Sisymbrium monense of Villars, and resembling somewhat 

 our own Brassica monensis, but much smaller, growing at a dis- 

 tance, from the sea, and in a hot climate. It had been disco- 

 vered by De Candolle, when Professor at Montpellier, and has 

 hitherto been found no where else. Indeed, it is doubtful if the 

 station be known to any one but De Candolle. He thus indi- 

 cates the locality : " Planities argillosa pone montem Lupi, in 

 pagos Londres et La Roque.'"' Londres was soon found ; but 

 as for La Roque, alas ! We searched diligently over several 

 plains all the way to Londres, but without success, and then 

 giving up the pursuit, we returned to St Martin by some mea- 

 dows. No sooner did we arrive at this village, where we were 

 to pass the night, than we discovered that we had been wander- 

 ing nearly all the afternoon in part of the individual " planities 

 argillosa''"* we were in quest of. La Roquette (not La Roque), 

 we found to be an old castle, and a very conspicuous one, too, 

 with a few farm-houses about it, and this the peasants we 

 had met with were in the habit of calling merely the Cas- 

 tello, and did n»jt know that it possessed the denomination of 

 di Roquett'i. Had we known, we might have examined the 

 plain with more attention, but, on account of its great extent, 

 it is not likely we should have been successful. I had, however, 

 no reason to be dissatisfied : much that I saw was new to me, 

 at least in the wild state. MM. Delile and Duval met us in 

 the evening. St Martin is a dirty village ; and as for the au^ 

 berge, it certainly had not cleanhness to recommend it. 



" Yesterday morning we started at 5 o''clock for the Capou- 

 ladon. Here grows the same species of Cyclamen that we had
