138 BOTANICAL INFORMATION. 



gera (the latter very rare), Epipactis ensifolia, some Euphor- 

 bias, Phyteumas, &c. ; and before I left Pau, the meadows 

 began to be covered with the showy flowers of Prunella gran- 

 diflora. In Cryptogamia my collection was much more 

 extensive ; but in proceeding to describe it briefly, it is neces- 

 sary to mention, that for want of sufficient leisure, and at a 

 distance from my books and herbarium, there are many I 

 have not yet ventured to name. The habitats are chiefly old 

 walls, trees, and shady banks ; for of rocks, properly so 

 called, there are none, the hills near Pau consisting entirely 

 of the debris of the Pyrenees, and offering conglomeration on 

 a grander scale than I have elsewhere seen it. The deep- 

 wooded ravines which intersect the " coteaux" of Jurancon, 

 so famed for their vineyards, afforded excellently-fruited 

 specimens of Orthotrichum crispulum, Hornsch., O. Ludwigii, 

 O. stramineum, and O. tenellum; besides which, I gathered 

 Fissidens grandifrons (a plant abundant throughout the Pyre- 

 nees in calcareous streams), Bryum erythrocarpum and tor- 

 quescens, Isothecium repens (Pterogonium, auct.), Trichostomum 

 crispulum; while the mutilated and decayed stems of chestnut- 

 trees were covered with Dicranum glaucum, and Leucodon 

 sciuroides, bearing a profusion of fruit, but out of season. I n 

 a visit which I paid to Pau, in November last, I secured them 

 both in excellent state. On old walls, at Jurancon and Ron- 

 tignon, I procured a large stock of Gymnostomum calcareum, 

 an interesting Moss, allied to our G. tenue, but having a ros- 

 trate operculum ; Bryum obconicum and atro-purpureum, the 

 latter, par excellence, the Bryum of the South of France; for 

 in the whole course of my peregrinations, I do not think I 

 have gathered Br. ccespititium above once, and Br. inclinatum, 

 or cernuum, once or twice ! The same walls produced several 

 Tortulas, the most abundant being T. revoluta, covered with 

 capsules ; and one is, perhaps, undescribed, if it be not the 

 Barbula flavipes of the Bryologia Europcca, of which I have 

 by me a scrap scarcely intelligible. T. inclinata was ju st 

 passing, but I was enabled to decide on its being truly dis- 

 tinct from T. tortuosa, which has been doubted by some crrn-
