Moist moors and among rocks, Ireland and the Highlands of Scot- 

 land, particularly in the north, not unfrequent. Fr. unknown. — 4—6 

 inches long, of a rich purple colour, growing in large tufts. The near- 

 est affinity of this species is the J. sphagnoides of St. Helena. 



40. J. complandta, Linn. (flat Jitngermannia); stem creeping 

 vaguely branched, leaves distichous imbricated above unequally 

 2-lobed the upper lobes larger orbicular, the lower ones ovate 

 appressed plane, fruit terminal, perianth oblong compressed 

 truncate. Linn. Sp. PI. p. 1133. E. Bot. t. 2499. Hook. Br.

Trunks of trees, frequent. Fr. throughout the year. — This forms 

 pale green, nearly orbicular patches, closely pressed on the bark of trees. 

 In habit, allied to J. platyphylla and dilatata ; but destitute of stipules. 



B. Stipidate. 



a. Leaves entire or rarely emarginate. 



41. J. anomala, Hook, (various-leaved Jungermannia); stem 

 procumbent simple, leaves orbicular roundish-ovate and ovato- 

 acuminate with large reticulations, stipules broadly subulate.

Bogs, not unfrequent. Fr. unknown — Gemmcs are found in small 

 balls, at the apex of the upper leaves, especially in autumn : and indeed 

 Mr. Wilson considers this as only a gemmiferous variety of the following 

 species, in which opinion he is probably right; the very large reticula- 

 tion of the foliage being common to both, while the chief character of the 

 present lies in its ovate superior leaves. 



42. J. Taylori, Hook. (Taylorian Jungermannia) ; stem 

 erect nearly simple, leaves all of them nearly orbicular with 

 large reticulations, stipules broadly subulate, fruit terminal, pe- 

 rianth ovate compressed at the mouth truncated and 2-lipped.

Moist rocks and boggy places in alpine districts. Fr. Spring. — This 

 species is extremely beautiful, of a rich purple colour, with reticulations 

 so large, that, when the plant is dry from the collapsing of the cells, its 

 leaves have, even to the naked eye, a distinctly dotted appearance. 



43. J. scaldris, Schrad. (ladder Jungermannid); stem creep- 

 ing simple, leaves roundish concave entire and emarginate, sti- 

 pules broadly subulate, fruit terminal, perianth combined with
