recurved margins, and wide cells. It is probably B. JRuthei var. 
rupincola Limpr., which seems referable to var. magus Boul. 
P. trichodeum Stirt. in Ann. Sc. N. H. xv. 113 (190(5). (Ben 
Lavvers ; 18(51.)—A small form of P. denticulatum with rather 
narrow leaves, somewhat more longly acuminate than usual. I can 
match it quite well with plants from the Midlands and elsewhere. 
Amblystegium geophilum Stirt. in Ann. Sc. N. H. xvii. 175 
(1908). (Port-na-Murrich, near Arisaig; 4 Sept., 1907.)—This is a 
small, erect, dense form of Hypnum chrysophyllum ; quite a marked 
form and worth varietal rank, but it must undoubtedly, I think, be 
placed under var. erectum Bagn. 
A. perminimum Stirt. in Ann. Sc. N. H. xvii. 175 (1908). 
(Budh-point, near Arisaig ; 2(5 Sept., 1906. Type-specimen.) (Loch 
Killisport; Sept. 1899.)—Stirton gives no locality in his description ; 
only “ in three localities ” ; “ in sandy ground near the sea.” The 
Arisaig plant must therefore be taken as the type. It is a very well- 
marked plant of A. serpens var. depauperatum Boul., a pretty form, 
with branches and leaves very homogeneous and regular. This variety, 
however, seems better sunk in var. salinum Carr. The Loch Killisport 
plant is a slightly different form of the same thing, and is nearer to 
the original form of var. salinum. 
Hypnum amcenum Stirt. in Ann. Sc. N. H. ix. 180 (1900). (Ben 
Lawers ; July 1886.)—Is an alpine form of Bracliytliecium rivulare\ 
perhaps var. latifolium Husn. or approaching it. 
H. annot ilium Stirt. in Trans. & Proc. Bot. Soc. Edinb. xi. 75 
(1873). (Ben Lawers; July 1863.)—Is Blagiothecium denticu¬ 
latum var. obtusifolium. 
II. anomalum Stirt. in Ann. Sc. N. H. xv. 112 (1906). (Ben 
Lawers ; July 1864.)—Stirton compares this with H. distans, i. e. 
Eurhynchium Swartzii. It is quite indistinguishable from that 
species.' The only character he suggests, which appeared to him 
anomalous, that of the asymmetry of the leaf-base, is quite normal 
for the prostrate branches of E. Swartzii. Several leaves of this 
form will be found among those figured on the two plates (524, 525) 
of Eurh. prcelongum (i. e., E. Swartzii ') in the Brv. Eur. 
H. corrugatulum Stirt. in Ann. Sc. N. H. xvi. 180 (1907). 
(“ On poplar trees, about 6 to 8 feet from the ground ; Loch Awe ; 
Sept. 1896.” As H. triquetrum var. corrugatulum.) —The corruga¬ 
tion of the leaves is very marked on some branches, very lio-ht on 
others. It is probably a form or state, possibly pathological, rather 
than a stable variety; it is a character not infrequent, sporadically, 
among various pleurocarpous mosses. Cf. H. intortum below. A 
second specimen (Bhu Load, Arisaig; 24 Sept., 1906) shows the 
same inconstancy of the character. 
H. dejlectens Stirt. in Ann. Sc. N. H. xix. 243 (1910). (Near 
Arisaig ; Aug. 1907 ; on a large ash tree.)—This is a rather striking 
form of II. cupressiforme , of an unusual habit; but certainly nothing 
more. 
H. intermixtum Stirt. in Trans. & Proc. Bot. Soc. Edinb. xi. 75 
(1873). ( Bracliytliecium intermixtum ; Ben Lawers; 1866.)— 
This is without any doubt Bracliytliecium paradoxum (H. f. & W.)
