 Coleochila Taylori, Dumort. Hepat. Europ. p. 107. 



Hab. On wet banks in subalpine parts of the country. This fine 

 species frequently grows in large patches among heath. On the 

 damp ground near mountain rivulets, where its purple- coloured 

 tops attract the eye of the collector, even when at a considerable 

 distance from the plant. 



2. Myliaanomala{^o6k.),'Q.(j:i2iY. Dioecious. This form, with the leaves 

 varying from roundish concave to nearly acuminate, generally 

 grows among Sphagnum. The late Dr. Taylor did not consider it 

 was even a variety. Dr. Carrington thinks differently, and de- 

 scribes in his Irish Hepaticee a character by which it may be 

 distinguished from M. Taylori. He states, "the cells are of a 

 different form from M. Taylori, containing curious fusiform cor- 

 puscles." Dumortier, in Hepaticse Europse, p. 106, gives it the 

 rank of a species. I have found both forms frequently growing 

 together, and so closely resembling each other, that it became 

 a difficult task to separate them.

Hab. Parasitic on the larger Hepaticse, especially Erullania tamarisci. 

 Pantry, Miss Hutchins. Tore Mountain, Dr. Carrington. On the 

 stems of trees, creeping over E. tamarisci, between the police 

 barrack and Upper Lake, Killarney. This singular minute species 

 appears to be confined to the Killarney district of Kerry. It may, 

 probably, turn out to be a Harpanthus when the fruit is found ?
