Dr. Taylor on fivo new species of British Jungcrmannise. 89 



Wales, Mr. G. J. Lyon at Campsie, and Mr. Spruce at Eskdalc ; 

 lately I have seen it at Blackwater Bridge and at Turk Waterfall, 

 both in the county of Kerry. Lindenberg too seems to have re- 

 ferred the present to Jun(/. pumila, With., from which the fol- 

 lowing marks will sufficiently distinguish it : 1. the paler colour ; 

 2. the larger size; 3. the leaves more distant, amplexicaul, more 

 concave, broader and rounder ; 4. their cells much larger; 5. the 

 calyx less exserted out of the perichatium ; 6. the calyx never acu- 

 minated, as is constant and characteristic in Jun^. pumila,Wiih.; 

 7. the calyx distinctly plicate above. From Jung, sphcerocmpa, 

 Hook., the present differs, — 1. by the larger and more procumbent 

 stems ; 2. the calyx plicate above, longer and less wide ; 3. the 

 leaves not exactly orbicular, but rather terminating in the figure 

 of a parabola. The present species approaches to Jung, autum- 

 nalis, DeCandoUe, which has been found not only on the conti- 

 nent of Europe but likewise in North America, and which may 

 be confidently looked for in the British Isles, where, however, it 

 has hitherto been unnoticed. In Jung, autumnalis, DeCand., 

 1. stipules are present, especially about the terminations of the 

 young branches ; 2. the leaves have a more vertical position, and 

 are more adpressed to the stem ; 3. their colour is rufescent, and 

 4. they are distinctly marginated.

It is very possible that Lindenberg's var. h. of Jung, bicuspi- 

 data, L., is the same as our plant, if we may judge from the scanty 

 description, but the species differ by numerous minute yet con- 

 stant marks. Jung, reclusa is, 1. of much smaller size, approaching 

 in this respect to Jung, byssacea, Both. ; 2. the leaves are shorter 

 than in /. bicuspidata, L. ; 3. they are more opake ; 4. more con- 

 cave ; 5. their shallower emargination is more rounded; 6. they 

 are more crowded; 7. they point to one side, viz. upwards; 8. 

 they are rotundato-ovate ; 9. their cells are more minute, and yet 

 separated from each other by larger vessels ; 10. the perichcetium 

 is shorter, and its leaves less acuminated; 11. the stems are wider
