BOTANICAL INFORMATION. 419 



been strangely overlooked by Bridel and others, though a 

 beautiful and well-marked species. Excellent original speci- 

 mens exist in the herbarium of Sir J. E. Smith, with the 

 following note in Swartz's handwriting : " H. denticulate 

 similis sed vera Leskea ; proxima L. pulchelUe sed diversa ;" 

 and I have myself authentic specimens given me lately by 

 MM. Bruch and Montagne. Another species of the same 

 genus is the L. Vaucheri of Schimper, which has been mis- 

 taken for L. attenuata, though a very different moss ; I have 

 seen it in several other stations in the Pyrenees. Leskea 

 subtilis and pulchella, Hypnum dimorphum, and callichrous, 

 Brid., were in excellent fructification, but H. umbratum had 

 lost its opercula. It was near the Pont d'Espagne that I 

 found on decayed wood the only splachnaceous plant I have 

 remarked in the Pyrenees ; it is probably a species of Tay- 

 loria. In the same place grew the handsome Mnium spino- 

 sum, and a Dicranum looking very much like longifolium, but 

 wanting the broadly-nerved leaf of that species ; I believe it 

 the D. Sauteri of Bruch. OrtJiotrichum rupestre and Hut- 

 chinsitB were in the greatest abundance, as were also several 

 species of Grimrnia, among which I recognized G. spiralis, 

 patens and ovata in good fruit; G. elatior, leucophoea and 

 commutata were rather advanced; and I have some others 

 which are quite unknown to me. In this valley, and espe- 

 cially near the Lac de Gaube, I added largely to my collec- 

 tion of flowering plants. The following are the most in- 

 teresting, and I can now speak on them with certainty : 



Ranunculus aconitifolius. 



Gouani. 

 Viola biflora. 

 Homogyne alpina. 

 (Tussilago, L.) 

 Pyrola uniflora. 

 Potentilla rupestris. 

 Spiraea Aruncus.
