 of Loch Awe above Taycreggan' pier. 



Philibert, in Revue bryol., distingvushes this species from M. orthorhynchum 

 by the taller lively green tufts and longer leaves, with larger cells. The European 

 plant was long supposed to differ from the Himalayan, but they are now generally 

 united. ' 



THUIDIUM PHILIBERTI Limpr. 

 Dioicous ; in lax yellowish-brown tufts ; bipinnate, paraphyllia vdth 

 filiform divergent branches. Stem leaves cordate ovato-lanceolate, with long 

 fine points, nerve f the length ; branch leaves ovate. Perich. bracts lanceo- 

 late, not ciliate, ending in a long recurved straplike subula. Apex of ramu-

Dioicous ; in loose yellowish-brown tufts, the stems prostrate, bipinnate, 

 with numerous filiform paraphyllia, with divergent branches composed of 

 quadrate cells which are broader at the upper ends than at the base, 

 branches and ramuli filiform. Stem leaves large, wide and cordate at base, 

 ovato-lanceolate, with long fine recurved points, 4-plicate, margin obsoletely 

 toothed, revolute in the lower half, nerve f its length ; cells incrassate, 

 longish oval, with a central papilla on both sides ; those of base elongate 

 and rectangular. Branch leaves ovate, concave, gradually acutely pointed> 

 nerved for f the length ; ramuline leaves ovate, acute, terminal cell trun- 

 cate, with two projecting points. Outer perich. bracts papillose, inner 

 lanceolate, biplicate, gradually narrowed into a long strap-shaped recurved 

 subula without cilia ; nerve ending below the subula ; cells lineal, 3 — 6 

 times long as broad ; seta red, capsule erect at base, curved-cylindric, 

 reddish-brown ; lid conico-rostrate, curving upward ; teeth yellow, papillose,

I found this moss nearly 40 years ago, on my first visit to Ben Lawers, and 

 laid it aside as a poor specimen of T. recognitum, and we owe it to Mr. Dixon's 

 sharp eye that its true character was detected ; it really comes nearest to T. deliea- 

 tulum.
