BOTANICAL. INFORMATION. 545 



After this digression to entomology, I must return to the 

 botanical portion of my narrative, and state that we quitted 

 our chamber as soon as external objects were distinctly visible, 

 in order to gather a remarkable thistle (Cirsium glabrum, DC), 

 which we had observed by a rivulet close to the inn, on enter- 

 ing it the previous evening ; and then, after taking our cho- 

 colate, we set out to return to Bagneres. The fatigues of the 

 previous day and the want of sleep, had very much unfitted 

 us for travelling, and we found the ascent to the Port almost 

 as difficult as that of the Maladetta. We gathered Campanula 

 pusilla, some Hieracia, &c. ; and I found mosses and lichens 

 about the Port itself, sufficient to occupy me above an hour. 

 They included Mielichqferia nitida, Grimmia conferta and 

 Sauteri, Gymnomitrium concinnatum, and a Hypnum, which is 

 quite unknown to me. We afterwards reached Bagneres-de- 

 Luchon without meeting with any adventure, or gathering 

 any plant worth mentioning. 



On the 4th of October I returned to Bagneres-de-Bigorre, 

 and as the weather rather improved after my arrival, I was 

 still able to take long excursions into the mountains ; and in 

 company with Dr. S. and M. Philippe, gathered several inte- 

 resting Cryptogamia. We were, in particular, well repaid for 

 a visit to Lac Lehou (sometimes called Lac Bleu), at the 

 extremity of the Vallee de Lesponne, made chiefly in quest of 

 lichens. We gathered Parmelia chrysoleuca, and Lecidea 

 Wahlenbergii, two of the most beautiful plants of the tribe, 

 on a ridge of schistose rock close by the lake ; besides Par- 

 melia cenea and chlorophana, Lecidea badia, Morio and con- 

 tigua (the var. called L. vmbilicata by Ramond), Biatora 

 olivacea and Tabacina, Cetraria nivalis and juniperina, Sticta 

 crocata, &c. In the same place grew Grimmia nigrita, Hypnum 

 moniliforme and some other rare mosses. The following are 

 also some of the more interesting rock-lichens, gathered on 

 Lhieris, B&lat, and other of the limestone mountains around 

 Bagneres ; viz. Parmelia cervina, chalybcea and crassa ; 

 Lecidea albo-ceerulescens and macrocarpa ; Biatora decipiens 

 and vernalis ; Gyalecta cupularis and txanthematica ; Verru-
