GEN. CHAR. Fruitstalks terminal; Peristome single, 

 of 16 entire, equidistant teeth; Calyptra dimidiate.

We cannot agree with Mohr in uniting this genus with the 

 Grimmice^ to which it bears a relation similar to that of Dldy- 

 modon to Trichostomum and of Gymnostomum to Anic tan glum ^ 

 genera which are now universally adopted. 



* Capsule with an apophysis. 



1 . W. splachnoides ; leaves Ungulate, rounded at the top, then 



nerve disappearing before the summit ; capsule obovate, apo- 

 physis obconical ; lid convex, acuminulate. (TAB. XIV.)

HAB. Turf bogs on the Scotch alps. 



Although this plant have the habit, leaves, capsule, am 

 apophysis, as well as place of growth of the Splachna, yet 

 the peristome. presenting teeth at equal distances decides 

 that it should be arranged under the genus fVeissla. The 

 species most nearly allied to the present plant is Splachnum 

 reticulatum, which, besides the configuration of the peri- 

 stome, may be known by its smaller size, much shorter fruit- 

 stalks, and ovate (not lingulate) leaves. In both the leaves 

 are remarkably obtuse, of a dark colour, strongly reticulated, 

 and glossy when dry. The Grimmia splachnoides figured in 

 English Botany represents our plant in the magnified cap- 

 sule, but not in the leaves. 



2. W. Templetoni ; leaves ovato-lanceolate, acute; capsule 



(with the apophysis) narrowly pyriform ; lid nearly plane.

HAB. Wet banks in various parts of Ireland. 



This species with the W. radians of Hedwig has the 

 same affinity to Funaria as Pterogonium has to Hypnum^ 

 viz. agreeing with it in general habit, and differing only ia
