Dr. Taylor on two new species of British Jungermannire. 89 



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

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

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

 ferred the present to Jung, "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 jjerichcetium ; 6. the calj'x never acu- 

 minated, as is constant and characteristic in Jung. j)umila,Vi^\\}i.; 

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

 Hook., the present diflers, — 1 . by the larger and more procuinbent 

 stems ; 2. the cal}^ 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, DeCandolle, 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, autumnaUs, DeCand., 

 1. stiprdes 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- coloiu- is rufesceut, and 

 4. they are cUstinctly niarginated. 



JuNGERMANXiA RECLusA, MSS. T. T. Caule repente, implexo, sub- 

 pinnato ; foliis approximatis, semiverticalibus, rotuudato-quadrati?, 

 bifidis, perichKtialibus majoribus erectis ; fructu ramulo proprio 

 insidente ; calyce cylindraceo-ovato, apice acuminato subtrigono, 

 ore denticulate ; capsula ovata. 

 In crj'ptis ericetorum Boream spectantibus, humidis, sa'pius occurrit 

 prope Dunkerron, Hiberuise. 



Cespites lati, tenues seu superficiales, fuscescentes, ex quibus caly- 

 cum apices plurimi, albidi, sparsim surgunt. Caules fiUformes, sub- 

 flexuosi, subpinnati. Foiia heteromalla, minutissima, magnitudine 

 folia Jung, bt/ssacece Roth, vix excedentia, latissima, ovata, bifida, seu 

 potius alte emargiuata, laciniis conniventibus, celluHs discretis, mi- 

 noribus. Stipulse nuUfe. Calyces ore albidi, subtrigoni, eminentes, 

 acutiusculi, dentati. 



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

 data, L., is the same as om* 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, Roth. ; 2. the leaves are shorter 

 than in /. bicuspjidata, 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 periclmtium 

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