Junerermania (Lophozia) alpestrls, Schl. {Jung, alpestris, 

 Schleich, Bxs., cent. 2, n. 59; Nees Europ. L,eberm ; 11., p. 104; G. L. et 

 N. Syn. Hepat., p. 113.) — Dioecious. Stem strong, creeping or erect 

 from the upper half, simple or divaricately branched near the apex, 

 clothed on the under side with white rootlets proceeding from the often 

 violet-coloured stem. I^eaves in two rows, vertical, increasing in size 

 from the base upwards, sub-quadrate, two-lobed, rarely three-lobed, 

 segments ot various depths, acute or obtuse, often widely and shallowly 

 notched at the apex, in some leaves sinus scarcely perceptible. Peri- 

 chaetial leaves three or four times acutely divided, stipules none. Peri- 

 anth obovate or obovate oblong, terminal or lateral. Antheredia 

 remarkably large, placed singly at the base of each leaf, which are 

 closely imbricated and saccate at the base, patent at the apex, recurved, 

 of a pale violet colour. Amongst damp rocks near the side of the River 

 Barrow at Graigue. Very rare.

 Jung, turbinata, Wils., in Kng. Bot Suppl., t. 2744, nee Raddi;. — Quarry 

 bank near Goresbridge. 



Nardia emarglnata, Ehrh. — Amongst damp rocks, side of the River 

 Barrow near the bridge at Graigue. Plentiful. 



N. scalarlSf Schrader. — Amongst damp rocks, side of the River 

 Barrow at Graigue. 



N. hyallna, Ivyell. — Moist bank in a plantation, Graigue. Rare. 



Pellla eplphylla, Di]l. (L-) — Damp places. Common. 



Conocephalus conlcus, Neck. — Banks of the River Barrow. 

 Common. 



Metzgrerla furcata, Ivinn. — On the trunks of trees about Graigue; 

 Oak Park near Carlow. Common. 



M. furcata, Linn. var. frutlculosa, Dicks. (Lindberg's Monogr. 

 MetMgeria ; Jungermania frutkulosa, Eng. Bot., Vol. 35, tab. 2514. /. furcata 

 var. ceruginosa, Hook., Brit. Jung., 55 et 56). On the trunks of trees 

 in the wood at Goresbridge. A very distinct form growing in compact 

 crisped tufts not unlike some large alga. Fronds tapered near the apex, 

 sharply forked, with the margins shallow and closely recurved, giving 

 the ramuli the appearance of being reduced to the nerve. Colour 

 near the apex a brilliant verdigris green, or blue green apex erect, bear- 

 ing copious gemmae. 



M. conjugata, fDill. (Lindberg's Monogr. Metzgetid), Autoecious. 

 Fronds robust, not much elongated, more or less dichotomous, irregularly 

 pinnated or decomposite, linear, narrower in some parts than in 

 others, in transverse section semilunar, hairs longish, stout, often 

 in pairs on margin and divergent. The paucity of hairs and more solid 

 substance of the frond with copious innovations, and above all the 

 autoecious inflorescence abundantly distinguishes this species from 

 Metzgeria furcata, which is dioecious, and all other known species of 

 this singular genus. On granite rocks, banks of the Barrow at Graigue 

 {fertile), on the trunks of trees in the wood near Goresbridge {fertile).
