Cepnatozia Turnert Hook. in Norra Wates. — Recently, in 
looking over my first collection of hepatics, made at Dolgelly, North 
Wales, March, 1875, I found associated with other species this rare 
and beautiful one. According to Dr. cine ase n Cepha- 
lozia,’ this species has only previously been found in the South- 
west of Ireland; Bantry (Miss Hutchins); Cromaglown (8. O, 
Lindberg). En ngland : Sussex, Tilgate Forest (Edw. Jenner, wees 
“aaa G. naigs 1879). France, Canary Isles, and Africa

eminent botanist, Prof. Hackel, of St. Poelten, on the Agrostis 
nigra With., noticed in this Journal for 1882 (pp. 65, "66: tab. 227), 
I recently sent him specimens of the plant, together with typical 
specimens of 4. vulgaris and 4. alba. A few days since I received 
a act courteous reply from Prof. Hackel, and, as his remarks oe
