of base, tapering upwards and ceasing a little below apex 

 by the breadth of two or three cells ; margin plane entire, 

 incurved in upper half so as to render leaf hollow ; no 

 auricles at base properly so called, but cells there next 

 nerve large, oblong attached, hyaline but with thickish 

 walls, -045--065 by -018-025 mm., outwards on the same 

 level cells about half the breadth, also hyaline, upwards 

 lessening until the rhomboid chlorophyllose prevail to 

 apex, a little longer at first, soon ending above into the 

 smaller, -01-013 by -007-01 mm. Near Plockton, September 

 1914. 



The next moss was discovered in 1913 near Plockton, 

 but although I searched the same locality closely next 

 year, only a few capsules, not quite ripe, were secured. 



This is a very singular moss, and I am not yet quite 

 certain that its systematic place has been determined. 



In large, lax, convex extended tufts of a deep or 

 livid green colour above, turning in time to a lighter 

 green, dark brown below ; steins upright from an inch to 

 an inch and a half long, slender, simple or sparsely 

 dichotomously divided ; leaves laxly or distantly arranged 

 around stem or from three to four in a complete whorl, 

 spreading when wet, slightly crisped or rather hooked 

 anteriorly in the upper half when dry, rather broadly 

 ovate below, lanceolate above and acute : nerve strong, 

 pale then a deep red, broad below, latit. near base, 11- 

 •16 mm., tapering to apex, which it reaches or very nearly 

 so, margin entire but broadly recurved near base, as much 

 as 04 mm., narrowing upwards to near apex, strongly 

 papillose as well as pagina ; alt. of papillae, 003--005 mm. : 

 leaves hyaline becoming slightly granular upwards, cells at 

 base long, undulating or even sinuose on margin, narrowly 

 oblong, rather widely apart, becoming brown as well as 

 the whole leaf, when also the undulations are nearly 

 obliterated, -04-06 by -005-007 mm., showing connecting- 

 tubes and pores with neighbouring cells, merging upwards 

 into shorter broader cells, apart, granular, -02-03 by 

 •007-009 mm., ultimately passing upwards into roundish 

 cells with irregular walls, showing bright points in a dark 

 ground, 009-014 mm. in slightly longer diameter: seta 

 long, slender, smooth, undulating with a wider deeper
