most shaded localities of southeru littoral aspect. la the 

 former stations the general form of A. decurrcns, for 

 instance, is that of a rounded, short, and thick-stemmed 

 tree, frequently attaining a height of eighty feet, smooth 

 barked, and lightly foliaged. The percentage of tannin 

 is also different, those on the dry slopes containing the 

 highest percentage of tan material. A. alpina is a low, 

 diffuse species, especially prolific on the highest altitudes. 



Nearly the whole of the different species of the genera 

 Daviesia, Pultena'u, Bosskm, and OxyloMum are prolific on 

 dry northern areas, especiall}^ the two last. Like the 

 Acacias, many species of Daviesia, as D. i-orynibosa and 

 D. ulicina, are greatly affected by hygrometric conditions 

 in their form and habit, especially D. latifolia, which 

 attains the size of a small tree at the 4000 it. level, north 

 of Mount Bogong, and is of high medicinal value. 



Similarly Pidtcuceo., MueUcri, and two Oxylohiums, 0. 

 alpestre and 0. ellipiicum, thrive in rich luxuriance in rocky 

 situations amid the snowy regions, their bright yellow and 

 brown Howers giving tone to the landscape. Among 

 JBoisiceas, B. hradeosa. and B. fuliosa are prolific on the 

 high tablelands at similar altitudes. Hovca lomjifolia 

 shows great variations in the form and thickness of its 

 leaves and in the depth of blue and purple colouring of its 

 iluwers. In the sub-alpine valleys, Kcnncdija raonojyhi/lla 

 (native sarsaparilla) tlourishes luxuriantly. 



ROSACE.E. — Two genera occur in the alpine and sub- 

 alpine areas, Riibus gunnianus and B. pavKifolius, -iOOO to 

 4500 ft., and Accetui ovina and A. Sanguisorhce, both 

 antarctic species, at 5000 to 6000 ft. The European 

 Alchemilla vulgaris ascends to 3000 ft. 



Saxifiiage.e. — Only one species, Bauera rahioides, is 

 seen at the 4000 ft. levels, although B. sessilifiora ascends 

 to 3000 ft. 



Onagre.e. — One species, the ubiquitous Epilohiiim 

 tetragonum, was observed up to 5000 ft. 



Salicarle. — The ubiquitous Lythrani Salic iria of 

 European type ascends to 4000 ft. in swampy areas. 



Halorage-i:. — Two species, Haloragis fcfra/jyaa and 

 Jlyriophyllum pcduncidntani, occur up to 4000 ft.
