BRITISH HEPATICJU. 27 



delays in the production of the work have been most vexatious, so that it is not to be 

 ■wondered at that the piiblisher objects to any change of plan. He has, hovever, pro- 

 mised that figures of any new species shall appear in a supplementary part. 



Below I append a brief diagnosis of the new species : — 



Nardia bepanda, Liadb. : Paroicous, stems more slender, fragile, ascending, 

 innovant, ramuli gracile ; leaves distant, subvertical, orbiculate, concave, saccate, and 

 amplexicaul at the base ; margin erect, more or less undulate, emarginate ; texture thin, 

 hyalne, the cells larger, thin-walled ; involucre obovate-clavate, bracts sub-reniform, 

 repand-lobate ; upper amphigastria ovate, 3-4 dentate ; pale green, ^ to | inch.

Prof. Lindberg states that this is the common form in Finland. It should be 

 looked for here, since I have received it from Cleveland, Yorkshire ; and from Forfar, 

 under the name of J. capUafa, the large variety of which it resembles in the delicate, 

 crisped, hyaline leaves, and large areolse.^ Ben Lawers, near Loch-na-ghat, Sept. 1862,

N. GEOSCYPHA (De Not.), Lindb. : Autoicous, smaller, barren stems very slender, 

 terete, creeping, radiculose ; fertile stouter, ascending only at the apex ; leaves accres- 

 cent, lower ones entire or emarginate, orbiculate, involucral leaves broader, repand- 

 lobate ; amphigastria rare on the barren stems ; tipper ones lanceolate, trifid ; involucre 

 immersed, seated at right angles with the stem, gibbous at its base, the cortical layer, 

 and rootlets purple j colour reddish-brown or purple, 2'" to 6"'.

Eesembling J. Genthiana in size and colour, but differing in the immersed colesule, 

 and peculiar structure of the involucre. 



N. geoscypha is one of those transitionary forms which are the puzzle and 

 torment of the systematise Except for the rudimentary colesule, the structure is 

 nearly identical with that of Acroholhus, 



The position of the parts may be better understood if we compare the creeping 

 shoot to the stem of a clay pipe, the head representing the involucre, and its tumid 

 , base the knob beneath.

* A friend informs me that Sa/rcoscyphus piceus, De Not. (p. 14), has never been 

 published, so that Dr. Gottsche's name K alpina must have preference. S. robustus 

 (p. 14) is also a MS, form of Be Notaris, not Lindberg.
