1014 CRYPTOGAM1A. MUSCI. Splachnum. 
near to S. urceolatum, from which it differs in the habit of its leaves, its 
slender and almost cylindrical receptacle. Dicks. 
Slender Gland-moss. Smith was of opinion that S. purpureum, With. 
Ed. iii. belonged to this species; but Hooker decidedly refers it to 
S. Mnioides. On Ben Lawers in the Highlands. On cow-dung about 
Llyn Id well. Mr. Griffith. E.) P. June—July. 
(S. lingula'tum. Leaves lingulate, rounded at the top, their nerve 
disappearing below the summit: capsule obovate: apophysis ob- 
conical: lid convex, acuminulate.

Mr. Arnott observes that this plant has each of the sixteen teeth geminate; 
a character which connects it with the genus Splachnum , and which is 
not to be found in any other Weissia. Its columella is also that of a 
Splachnum. But Prof. Hooker states that there are sixteen distinct 
equidistant teeth; each, indeed, having an evident line, and even a 
slight furrow down the centre, but it is never split nor perforated. Stems 
two to four inches and more in length; below generally decumbent, 
(from the usual current of water,) and simple, with numerous downy 
radicles, blackish; above erect, branched, deep green. Leaves deeply 
imbricated,f erecto-patent, oblongo-lingulate, very obtuse, entire, some¬ 
what undulated, reticulated with oblong areolae , furnished with a nerve 
of the same colour which disappears below the apex; the lower ones, as 
if from decay, of a blackish brown colour; uppermost ones deep green. 
Fruit-stalk flexuose, deep red. 
Tongue-leaved Gland-moss. S. lingulaium. Dicks. Sm. Brid. Weissia 
Splachnoides. Hook. Tayl. This Moss has attracted much atten¬ 
tion, both from its rarity, and the difficulty in determining its genus. 
It was first discovered in Scotland by Mr. Dickson: has since been 
found on Ben Lawers by Mr. G. Don; on Ben Lomond by Mr. D. Don; 
and by Prof. Hooker in muddy declivities, in profusion at the foot of 
Ben Cruachan, between Craigalleach and Meal-greadha, in Aug. afford¬ 
ing a spectacle such as few Museologists have had the opportunity of 
witnessing. E.) 
S. F rcelichia'num. Capsule a club-shaped termination of the fruit- 
stalk : leaves battledore-shaped. 
Hedw. Stirp. iii. 40. 
Leaves folded when dry ; with much moisture they lose their colour at the 
edges, thence attaining a membranous appearance. The nerve or 
keel does not extend to the extremity of the leaves. Fruit-stalks pale 
upwards, of a fine pink colour near the base. Capsule a continuation of 
the fruit-stalk, inversely egg-shaped. I have not observed any teeth. 
Griff. Plant about an inch high. Leaves of a beautiful green, broadest 
at the end; mid-rib indistinct, hardly discernible in the lower leaves. 
Fruit-stalks half an inch long. Receptacle very short, and only to be 
distinguished from the fruit-stalk and capsule when the latter is ripe. 
Hedwig says the mouth of the capsule has eight pair of teeth, which 
always stand upright and never expand, as in the other species. 
(Frcelichian Gland-moss. E.) Specimens sent me by J. W. Griffith, 
Esq. who first discovered it growing on the eastern side of Snowdon, 
about one hundred and fifty yards from the summit. P. Autumn,
