NEW AND RARE MOSSES FROM SCOTLAND 243 



in most instances, apiculate, length .O7-.O85 mm,; margin 

 entire, narrowly recurved from base to near apex, reflexed 

 on an average, .015 mm., more broadly so near base, nerve 

 broad near base, quickly splitting into two diverging branches 

 which extend up a third of the leaf; general cells above, 

 large, elongate-hexagonal or merely fusiform, .o8-.i I by 

 .OI3-.OI7 mm., a little broader near base and at basal 

 alae nearly quadrate, marginal cells, in 2 or 3 longitudinal 

 rows, much narrower and even longer ; no primordial utricles 

 seen in cells. Leaves often show, under a Codington lens, 

 minute prominent points on the back ; inflorescence peculiar, 

 seen in the axils of the lower smaller leaves of the stem, as 

 very minute compact buds having bracts so short as often 

 to allow the red archegonia to be seen, some buds showing 

 archegonia mixed with pale antheridia, others only antheridia. 

 According to Dr. Braithwaite the moss is polygamous as in 

 Flag, succulentnm (Wils.). Barren. 



On black soil, generally near or on the old stumps of 

 trees in the original, very probably primeval, forest of 

 Arisaig. 



I feel constrained to record here the description of a 

 moss which has close affinities to Hypnuni cupressiforme. I 

 have waited for several years in expectation of finding it in 

 fruit, but hitherto without success. It presents peculiarities 

 such as I have never seen in any of the species grouped 

 around H. cupressiforme, much less in any of the numerous 

 forms assumed by this moss. H. incurvatum has perhaps a 

 nearer relationship to it than any of the other allied species. 



Hypnuni deflectens. In large broad flat sheets with a 

 beautiful silky sheen a sheen retained for years in the 

 herbarium of a dark or bluish-green colour ; main stems 

 below, brownish, slender, creeping, irregular, nearly bare, 

 whence originate numerous closely arranged, nearly parallel 

 branches, all pointing in nearly the same direction, all pro- 

 strate but arcuate in a downward direction, curved from 

 a third to nearly a half of a circle, each about an inch long 

 and rather more than a millimetre in breadth throughout, 

 with blunt slightly incurved extremities, forming nearly flat, 

 broad bundles, all such closely arranged as well as closely 

 connected to the other bundles, so as to constitute a large
