5. ScapaniauUginosa {'^eeB),Dumori. Stems ascending. Leaves con- 



duplicate, unequally bilobed, the lobes roundish and entire in the 

 margins, larger lobe anteriorly reclined, smaller about one-fourth 

 the size of the larger lobe. Colesule entire at the mouth.

Hab. Marshy places among heath on the mountains. Near the Hunting 

 Tower, Cromaglaun (1875) ; Connor Hill, Co. Kerry (1873). 



6. Scapania irrigua, Nees (Dumort.) Stems creeping. Leaves bi- 



lobed, conduplicate, lobes very unequal, anterior lobe much the 

 smallest, and curved at the apex. Involucral bracts bifid, lobes 

 nearly equal. Colesule ovate, compressed, toothed at the mouth.

Hab. Marshy wet places among the hills. Knockavohlla, Co. Kerry, 

 Dr. Taylor. Cromaglaun ; Marsh on Benbulbeu, Sligo ; Lough 

 Bray, Wicklow. This plant bears more of general resemblance to 

 S. nemorosa than it does to S. undulata. Only small portions of 

 it were collected in the localities mentioned. 



(c). Leaves longer than hroad ; lobes more or less acute. 



7. Scapania cequiloba, Damort. Dioecious. Stems loosely tufted, ascend- 



ing. Leaves bilobed, the lobes large, nearly equal, dentate, lower 

 lobe roundish-ovate, apiculate. Colesule oblong, compressed, 

 mouth oblique, truncate, denticulate, scarcely longer than the 

 involucral bracts. Capsule ovate.

Hab. Rocky places in subalpine countries. Near the head of Glenifp, 

 Co. Leitrim (1875), growing near Saxifraga nivalis. This is the 

 only Irish locality I feel safe in quoting for this species. All the 

 other Irish specimens I have seen, which have been named S. 

 aequiloba by some of our best authorities, are states of Scapania 

 resupinata, Dumort. = Martinellia gracilis, Lindberg. The verru- 

 cose epidermic layer of the areolation of the leaves, first observed 

 and pointed out by Dr. Lindberg, seems the only real character 

 by which this plant can be distinguished from its near allies. 



8. Scapania restipmata, Dximort. Dioecious. Shoots in crowded tufts 



for the most part, but sometimes more lax and scattered, mostly
