ACOTYLEDONE^ VaSCULARES. 



1. Rhizospermee. 



1. Azolla magellianica (F. v. M.). — Is abundant in the still 



waters of sub-alpine pools, along the courses of the 

 Livingstone Creek, especially near Orneo, at an eleva- 

 tion of 2200 feet, where its bright green, red, or 

 purplish imbricated leaves form a carpet-like coating 

 on the surface. 



2. Lycopodineae. 



2. Lycopodium Selago (Linne). — This handsome club- 



moss is most abundant in the shaded crevices of 

 granitic rocks, near the summits of Mount Kosciusko, 

 at elevations between 6000 and 7000 feet. 



2. Lycopodium clavatum (Linne). — On the gravelly 



depressions (old miocene river-beds) at the lower 

 levels of the Dargo High PlaiDs ; this interesting 

 species is found at an elevation of 4000 feet ; and also 

 near the summits of Mount Kosciusko, in similar 

 situations to L. Selago ; in the latter place in a 

 slightly altered form. 



3. Lycopodium densum (Labill.). — On the porphyritic 



areas near Mount Cobboras, between 3000 and 5000 

 feet elevation. 

 1. Selaginella Preissiana (Spr.) — In similar habitats to 

 Lycopodium densum, but exhibiting great variety in 

 the length of its stem, and in the character of its 

 foliage, being more close and dense at the higher 

 elevations. 



2. Filices. 



1. Ophioglossum vulgatum (C. Bauh.). — Common on the 



subalpine flats of the metamorphic schists near Omeo; 

 2000 to 3000 feet elevation. 



2. Botrychium Lunaria (Swartz). — The common British 



moonwort ; also occurs on the flats of the Livingstone 



Creek. 

 2. Botrychium ternatum (Swartz). — In the moist glens of 



Silurian rocks in the Macalister River sources at 



elevations of 2000 and 3000 feet. 

 1. Hymenophyllum Tunbridgense (Sm.). — This beautiful 



and delicately fronded fern is very prolific in the
