abound the following, viz. — Philonotis, several species; 

 Splachnum vascidosum, Mniiiin cinclidioides, and several 

 allied species ; Hypnum exannidatum, H. falcatum, Thui- 

 diuvi decipiens, Wehera albicans, var. glacialis, and 

 numerous other interesting plants. 



Webera Ludwigii differs in its narrower, hardly concave, 

 patulous leaves, more strongly decurrent ; with larger, longer, 

 and more diaphanous areolse. The whole foliage also is 

 frequently of a fine red colour. Fruit matures in August. 

 Habitat : Abundant on the fine debris of granitic rocks, 

 by streamlets issuing from the perpetual snow beds near 

 the summits of Ben-mac-Dhui, Ben-na-Boord, and doubt- 

 less all the other mountains of like character. On the slaty 

 formations it is rare, and I have only seen it by a streamlet 

 in one small ravine above Glen Callater, where in the 

 middle of July the snow was lying abundantly. 



Webera Schimperi, VVils. (not of B. &; S. Bry. Eur.), has 

 leaves more rigid, erect, narrow lanceolate, less decurrent ; 

 nerve stronger, continued almost to the apex ; areolse a little 

 longer, more obscure. Fruit matures in July. Habitat : 

 Frequent on debris of micaceous rock, on Ben Lawers, and 

 on most of the other Perthshire mountains. It also occurs 

 on debris near the summit of SnovvTlon, but barren. 



Philonotis adpressa, Ferg. Plant widely coespitose, erect, 

 two or three inches liigh, either dull glaucous green, or with 

 a fine red tinge ; leaves papillose, when moist erect, with one 

 wide plica on each side of the nerve, incurved towards the 

 apex, when dry slightly twisted, widely ovate, from an am- 

 plexicaul base, not acuminate, apex either obtuse and 

 cucuUate, with a very slight mucro, or in the more slender 

 forms of the plant rather acute; margin denticulate, slightly 

 reflexed; nerve very thick, continuous; cells in the upper 

 part of the leaf small ovoid, towards the base a little shorter 

 and wider. I have seen neither flowers nor fruit. 



Habitat : Glen Prossen, Clova, and various other places 

 in the Clova district — Rev. J. Fergusson. Glas Mheal,
