U4, H E PAT I CM. [Jungermannia. 



Moist rocky places, Ben a bord and Ben y mac Duich, Scotland, Mr. 

 Don, (at which latter place Mr. Arnott and myself gathered it abund- 

 antly in 1830, growing with J. Doniana.) Summit of Brandon mountain, 

 Ireland, Dr. Taylor. Cwm Idwel, N. Wales, Mr. Wilson. Fr. un- 

 known. — The lobes of the leaf are, in this remarkable species, separated 

 nearly to the base, so that they may be said to form distinct leaves. 

 This species has been observed by Mr. Wilson to have a very fetid 

 smell, resembling Castor, giving out its odour while drying and on being 

 again moistened. The plant and its foliage are among the largest of 

 this groupe, and of a yellowish-brown colour. 



31. J. umbrosa, Schrad. (shady Jungermannia); stem nearly- 

 erect somewhat branched, leaves unequally lobed the lobes 

 conduplicate their apices serrated acute, the upper ones round- 

 ish-ovate the lower ones larger ovate, fruit terminal, perianth 

 oblong incurved compressed, the mouth truncated entire.

 Wilson.) Fr. March, Apr. — Considerably smaller than the two pre- 

 ceding, and serrated only at the extremity of the leaves. 



32. J. unduldta, Linn, (wavy-leaved Jungermannia); stem 

 erect dichotomous, leaves unequally lobed waved the lobes 

 conduplicate roundish entire or very obscurely crenulated, the 

 lower ones much larger, fruit terminal, perianth oblong incurved 

 compressed, the mouth truncated entire or nearly so. Linn. Sp.

 to belong to J. scalaris. ) Hook. Br. Jung. t. 22. Hobs. Br.

Wet places, among rocks in streams and in springs, alpine countries, 

 abundant. Fr. May. 



33. J. resupindta, Linn, (curled Jungermannia); stem pro-

Banks and in woods. Fr. Spring. — Much smaller than the last, with 

 procumbent stems, and nearly equal concave conduplicate but closely 

 appressed lobes of the leaves. 



34. J. albicans, Linn, (whitish Jungermannia); stem erect 

 slightly divided, leaves unequally 2-lobed the lobes conduplicate 

 with a pellucid line in the middle serrated at the point the 

 upper ones oblongo-ovate acute the lower ones larger some- 

 what scymitar-shaped, fruit terminal, perianth obovate cylindrical 

 subcompressed, the mouth contracted plicate toothed. Linn.
