64 HEPATIC^. \Jungermannia. 



On the ground, among mosses ; common. The calyx, perhaps, 

 would be better called pensile : it is by no means immersed in the 

 soil, but attached by the neck on one side, it hangs down freely. This 

 applies to the next species. 



52. J. Trichomanis, DICKS. Stem procumbent ; leaves flat, 

 convex, ovate or emarginate ; stipules rotundato-lunulate, emar- 

 ginate; fruit dorsal; calyx subterraneous (pensile), oblong acu- 

 minate, fleshy, hispid, the mouth crenated. Dicks. Cr. Fasc. 3, 

 t. 8, / 5 Hook. Br. Jung. t. 79. 



On wet soil ; common. The stipules sometimes 3 4-fid ; the 

 leaves are occasionally glaucous, usually of an apple green ; the 

 capsule lineari-oblong, its valves spirally twisted. 



b. Leaves bi-tri-fid, or partite, segments equal. 

 * Stipules very small, distinct. 



53. J. bidentata, LINN. Stem procumbent; leaves broadly 

 ovate, decurrent, emarginate, acutely or obtusely bidentate ; sti- 

 pules bi-tri-fid, laciniated; fruit terminal; calyx oblong, trian- 

 gular, the mouth laciniated. Linn. sp. pi. p. 1598. Hook. Br. 

 Jung. t. 30. Jung, heterophylla, Schrad. in Journ. Bot. 5, p. 66.

On moist mossy banks ; common. On the specimens from Black- 

 water Bridge, County of Kerry, I find the calyces acutely triangular, 

 with the angle corresponding to the inferior side of the stem serrate. 

 As I have found some specimens which, with the utmost care in the in- 

 vestigation, I could not refer to one more than the other species quoted, 

 I have ventured to unite them. 



54. J. scutata, WEB. ET MOHR. Stem procumbent; leaves 

 rounded, acutely emarginate at the top, the segments acute 

 straight ; stipules large, ovate, acuminate, subdentate at the base ; 

 fruit lateral ; calyx obovate, subplicate at the top, the mouth 

 contracted, bluntly toothed. Web. et Mohr, Cr. Germ. p. 408.

Near Bantry, Miss Hutchins* Lough Bray, on exposed rocks* 

 Turk Waterfall, near Killarney, Mr. Wilson. 



55. J. Francisci, HOOK. Stem nearly erect ; leaves ovate, 

 concave, acutely emarginate ; stipules minute, ovate, bifid ; fruit 

 terminal upon short proper branches; calyx oblongo-cylin- 

 draceous, the mouth toothed. Hook. Br. Jung. t. 49. 



Near Bantry, Miss Hutchins ; very rare. 



56. J. barbata, SCHREBER. Stem procumbent; leaves ro- 

 tundato-quadrate, tri-quadrifid ; stipules lanceolate, acutely bifid 

 and laciniated ; fruit terminal ; calyx ovate, the mouth con- 

 tracted, toothed. Schreb. Spicil. Fl. Lips. p. 107. Hook. Br. 

 Jung. t. 70. 



On turf banks, with mosses ; rather rare.
