periantlis and amentse, the shape and red colour of the leaves, espe- 

 cially those of the lower plane, all come into view. Still, we doubt 

 if the occurrence of the red colouring matter is peculiar to Lejeunea 

 Soltii. 



Lejeunea jiava grows on the trunks of trees and among mosses, and 

 the larger Hepaticse, and on moist rocks very sparingly ; Lejeunea 

 serptjllifolia is abundant on trees, and on rocks in the bed of the 

 stream, and presents many curious forms. Such is a brief account of 

 some of the rare hepatics we gathered as we slowly worked our way 

 up the stream, and the day was far spent when we arrived at the wall 

 of rocks down which the water tumbles with a loud noise. On the 

 right hand side of the fall is a rocky terrace, covered with Trichocolea 

 tomentella, and festoons of Miss Hutchin's Jubula, golden Hypnums, 

 and the silvery Hooheria lucens, backed up with a frondose denizen of 

 the tropics, Lumortiera hirsuta, var. irrigua, which clothes the rocks ; 

 the lurid green colour of its fronds is striking ; sparkling in the sun- 

 shine are the drops of spray with which it is bathed by the waterfall ; 

 it is a fitting background for this exuberance of tropical growth — a 

 veritable garden of cryptogams. We followed a well-kept pathway 

 to the summit above the fall, and got some excellent views of the 

 lower lakes and distant mountains. Who can describe the variety of 

 shades and colours of the surrounding woods and mountains in the 

 setting sunshine, and we both exclaimed, verily Killarney's beauty is 

 not overrated. 



The following list which is provisional only, contains forty-seven 

 species, many of which are very rare, as Lejeunea diversiloha, &c., and 

 six varieties, some of which are of botanical value on account of con- 

 stant characters and local distribution. In the arrangement of the 

 Lejeunea we have grouped them into sections which correspond to 

 the sub-genera into which Dr. Spruce divides them in his grand work 

 on the Hepaticse of the Amazon and Andes, where the species of 

 Lejeunea are numerous. We trust it may be useful for identification 

 and reference to the students of these curious plants.
