case of the JDipliysdum , it is “ the sort of thing that might happen 
to anyone.” 
Bryum elegantulum Stirt. in Scott. Bot. Rev. i. 92 (1912). 
(Lovedale, near Gairloch, Ross-shire ; Aug. 1911.)—Stirton compares 
this with B. argenteum , but a glance at the tufts shows that it lias 
no close affinity with this. It is pale green, with very close, slender 
stems and large axillary gemmae in their upper part. It is, I think, 
practically identical with B. Barnesii , and I should refer it, with 
that, to B. atropurpureum var. gradient uni Tayl. (which, it must be 
confessed, is a somewhat heterogeneous collection !). It differs from 
the ordinary forms of that —like B. Barnesii —in the point of the 
upper leaves being longly acuminate, but in other characters it comes 
very near B. atropurpureum. 
B. intortulum Stirt. in Trans. Bot. Soc. Edinb. xxvi. 428 (1915). 
(Near Plockton, Ross-shire ; Sept. 1911.)—This is one of the forms 
of the very variable B. pseudo-triquetrum ; the d plant, tall, luxu¬ 
riant, with narrow, rather Haccid leaves—with, in fact, more of the 
habit that one associates with B. hi mum, but it is, according to 
Stirton, dioicous. Such forms may be seen in most large collections. 
Spruce, Muse. Pyren. 129, is a very similar one. It may be the var. 
angustifolium Lindb., which I have not seen. It is quite a marked 
plant m habit, but only departs from type in habit and narrowness 
of leaves. 
B. leptaleum Stirt. in Ann. Sc. N. H. xii. 113 (1903). (King’s 
Seat, near Killin ; I). Haggart, 1901.)—Stirton compares it with 
B. barbatum, which he says has much larger leaves and larger cells ; 
this is to some extent true, but the difference does not go much 
bej'ond that. It is certainly only a rather better marked form of 
B. capillare var. elegans than B. barbatum. The areolation is 
sometimes very regularly and prettily hexagonal. 
B. obrutum Stirt. MS. in herb. Two specimens under this name 
are rather interesting; the first (Ben Voirlich by Loch Lomond, 
1864) appears to be a form of Webera Ludwigii ; but it may 
possibly be a slightly altered form of the second (Ben Lomond ; 
J uly 1864) which is, I think, without doubt a robust form of 
Webera cucullata ; the perichsetial leaves, which are present, narrow 
and with narrow cells, seem to belong here, while the leaves have the 
catenulate arrangement, wide, subcucullate apex, and thin-walled 
cells characteristic of the species. 
B. parasemum Stirt. in Ann. Sc. N. H. ix. 178 (1900). (Sands 
near Stevenson; 1863.)—The leaves show a good deal of variation in 
apex, mostly very cucullate and obtuse; large single gemmae very 
frequent in the leaf-axils. It has every appearance of being an 
abnormal form of some common species, either B. argenteum or 
B. atropurpureum ; the stems are less than 1 cm. high. 
B. perpusillum Stirt. in Glasgow Nat. vi. 38 (1914). (Lovedale 
Woods, near Gairloch ; July 1911.)—This is a B. argenteum form; 
stems an inch in height, dark green ; leaves chlorophyllose almost or 
quite to the apex, highly cochleariform, mostly apiculate or cuspidate. 
It would come under var. majus. 
B. rubicundum Stirt. in Trans. Bot. Soc. Edinb. xxvi. 246 (1914).
