Var. p. integrifolia, IS'ees [Plate 45]. 



This appears to me a very distinct plant from the typical form of the 

 species. It differs : 1, in the leaves being more obovate and 

 less spinulose at their margins ; 2, in the absence of an auricle to 

 the margin of the leaf ; 3, in the amphigastria being smaller, and 

 the margins of their lobes more entire ; 4, in the smaller size of 

 the plant, and its olive-green colour. — The colesules are terminal 

 on the main branches, and on their middle. They are trigonal 

 as in the typical form. The andi'oecium consists of small amenta, 

 which proceed from the middle of the stem branches (autoecious). 

 This remarkable plant was collected by Professor Lindberg and 

 myself at Connor Hill, in July, 1873. 



The few specimens I had were imperfect, and without colesules. 

 In 1875 one of our garden assistants, Mr. D. Macardle, collected 

 it in larger quantity in Maghanabo glen, near Castlegregory, 

 Co. Kerry, growing over the fronds of Dumortiera irrigua. The 

 jjlants he brought were more perfect, having both the gynoecium 

 and androecium in good condition. I have carefully examined a 

 number of these, and cannot find on any of them auricles to the 

 leaves. On some, I have observed the slightest folding-in of a 

 minute tooth-like portion, where the auricle ought to be. The 

 amphigastria are minute, not more than half the size they are in 

 the typical form. I have, however, no doubt that our plant is of 

 the same kind as that noticed (G. L. et 'E. Synop. Hep. p. 426) 

 as having been found in the island of Javaby Blume; the note of 

 observation by Dr. Grottsche, which is appended, having reference 

 to his Java specimens, confirms me in this opinion. Professor 

 Lindberg, in his paper on Hepaticse collected in Ireland, states that 

 this plant is found in North America and in the island of Java.
