Dr. Taylor on some new British Jungermaniiiie. 13 



green. Stems 1 — 2 inches long, irregularly branched, scarcely 

 pinnate, branches short, patent. Jjeaves oblongo-rotundate, some- 

 times a little narrower at the toj), quite entire ; their strvicture 

 densely and minutely cellular. The lower lobe is more minute 

 in proportion to the upper than in any of the congeners : the sti- 

 pules are scarcely wider than the stems. 



Through the kindness of Dr. Gottsche, who sent me specimens 

 from Hercpiia, I have been enabled to identify this species, which 

 I had long considered something more than a variety of Jung, 

 platyphylla, L. The fructification I have not seen.

On sandy banks of streams in woods, at Gertagaree and Black- 

 water, ce. of Kerry. 



Tufts wide, dark green. Stems about an inch high, sparingly 

 branched, curved at the top. Leaves convex towards the anterior 

 margin. 



Dillenius distinguished the present from Jung, asplenioides, L. ; 

 they have been confounded by all succeeding writers. This spe- 

 cies may be recognized by the obovate leaves, which have no ap- 

 pearance of being truncate at their tops ; by their being more 

 crowded, nearly vertical, dentate throughout ; by both their mar- 

 gins being recurved, and hence appearing convex in front ; by 

 their less patent position, by the greater length of their deeurrent 

 bases, very essentially by their smaller cellules ; and by the mouth 

 of the calyx having large crenulations, which are themselves den- 

 ticulate. Besides, the tufts are of a darker green, and the shoots 

 more slender.

On recks ever which water continually trickles. 



Patches wide, shallow, brownish olive. Stems 1 — 4 inches 

 long, irregularly pinnate ; the branches nearly at right angles to 

 the stem. Leaves from a narrow base, flatly cup-shaped ; their 

 lower lobe swelling out at its involution, while their angulate tops 

 lie closely adpressed to the inside of the upper lobe.
