the upper part of main stem (bare of branches) has leaves 

 more abruptly narrowed into the slender acumen, which 

 is often twice the length of leaf proper, and when dry very 

 often assumes a curled or cork-screw appearance, as in 

 T. tortuosa ; branch leaves much smaller and less expanded 

 at base, spreading also, but otherwise resembling the main 

 stem leaves ; cells at basal margin form a fairly well de- 

 veloped group, broadly oblong, detached with thickish 

 walls, '018-027 by 01-015 mm. ; general cells narrowly 

 oblong but narrowing a little towards the extremities. 

 •06--08 by 0035--004 mm. 



Only one long, strong, red seta was seen without the 

 capsule, surrounded at its base by pale, sharply pointed., 

 slightly spreading leaves ; and on the same stem, within a 

 short distance from the seta another minuter bud, also 

 pale, probably enclosing the male inflorescence. Near 

 Plockton, Ross-shire, 1913. 



As I consider the matter one of importance, I make no 

 scruple in calling attention to the next moss. It is known 

 in the field by the dense convex tufts, dark green above 

 with a pale zone just beneath, then of a uniformly dark 

 brown colour to the base, as well as by the leaves with 

 short, almost equal, hair-points. This moss has been 

 under observation for years. In my opinion, it is diverging- 

 from C. abrovirens. The basal areolation diverges most. 

 Cells next the nerve below, in three to five perpendicular 

 rows, are thick-walled and oblong, 03-04 by -01 8-025 

 mm. ; directly outwards, towards margin, cells become 

 narrower and thinner walled until near and at margin, 

 in many rows, linear and hyaline, '018-027 by - 004 mm. 

 Even the upper cells are somewhat different, nearly linear 

 in place of sigmoid, granular. 028-045 by -004-006 mm. 

 The auricles are small (smaller than usual), hollow, and 

 contain only a very few (six to eight) large oblong, attached 

 cells, brown, - 04 by "03 mm. 



I may have another opportunity for ventilating this 

 subject further. Meanwhile this moss may be named 

 Campylopu8 perplexans, inasmuch as I sympathised with 

 Wilson with regard to another specimen named C. 

 pa radox u s ( Wils. ).
