abound the following, viz. — Philonotis, several species; 
Splachnum vasculosum, Mnium cinclidioides, and several 
allied species ; Hypnum excmnulatum, H. falcatum, Thui- 
dium decipiens, Weber a albicans, var. glacicdis, and 
numerous other interesting plants. 
Webera Ludwigii differs in its narrower, hardly concave, 
patulous leaves, more strongly decurrent ; with larger, longer, 
and more diaphanous areolae. 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, Wils. (not of B. & S. Bry. Eur.), has 
leaves more rigid, erect, narrow lanceolate, less decurrent ; 
nerve stronger, continued almost to the apex ; areolae 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 Snowdon, but barren. 
Philonotis adpressa, Ferg. Plant widely ccespitose, erect, 
two or three inches high, 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, nob acuminate, apex either obtuse and 
cucullate, 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 Hheal,
