NEW AND RARE SCOTTISH MOSSES in 



widely spreading but scarcely squarrose, broadly cordate 

 below, rather longly and slenderly acuminate, slightly 

 decurrent at the base, striate or even sulcate when dry in the 

 lower half, margin plane, minutely but distinctly serrated 

 throughout, serratures formed by the sharply pointed cells ; 

 cells of general areolation long, sharp-pointed, and narrow, 

 50 to 80 by 4 to 6 /A, broader near the base, a little shorter 

 and narrower towards apex, alar spaces well defined, of 

 4 to 9 longitudinal rows, cells ovate, concolorous, 20 to 30 

 by 8 to i I fj, ; nerveless or very faintly two-nerved at the 

 base ; branch-leaves narrower, ovate-acuminate often slightly 

 secund, not spreading so much, alar spaces not so well 

 defined ; perichxtial leaves paler, closely imbricated, the 

 outer with long, almost setaceous acumina, which are also 

 widely spreading, inner much more shortly pointed, and 

 more laxly areolated ; seta smooth, strong, thick, and long, 

 deep-red ; capsule large, long, and arcuate, lid large, convexo- 

 conical, with a longish sharp point. Spores brown, spherical, 

 smooth, ii to 14/1, in diameter. Perigonia bud-like on the 

 main or secondary stems, with leaves shorter and less 

 pointed. Killin ; close to streams, on boulders which are at 

 times submerged. 



There are only two capsules left, not quite ripe ; accord- 

 ingly the teeth cannot be examined. While the lid and seta 

 are fully coloured, the capsules remain a deep green, although 

 the spores within are brown and apparently fully formed. 



The smaller form discovered on Ben Lawers grew inter- 

 mingled with the very rare Hylocomium Oakesii in one of 

 the most prolific spots on the mountain. Besides being 

 smaller in every way, the stems are more closely and shortly 

 pinnate, with the leaves on the main stems squarrose but not 

 sulcate, and much more abruptly and longly acuminated. 



Until more extended observations can be made, I shall 

 name this a variety under the name ininusculuni. 



With reference to the station on Ben Lawers, I feel 

 constrained to state that on a subsequent visit I saw at a 

 glance that plants of almost every description had been torn 

 away from it, and nothing left except a few straggling grasses 

 and a small tuft of AlcJiemilla vulgaris. That this oblitera- 

 tion was the work of a botanist scarcely admits of a doubt.
