316 NOTKS ON NATIVE FLORA OF NEW SOUTH WALES, VIL, 



Plants absent from Monaro. 



Owing chiefly to climatic reasons, several of the well known 

 groups of New South Wales trees are absent from the »rea 

 described in this paper. No species of either Ironbai k or Box, 

 not even a Yellow Box {Eiicalijfiiis melliodora) was notic« d, 

 though it ascends as far as Collinton. Sterculia diversifolia G, 

 Don, the well known Currajong, was not seen, and usually 

 prefers warmer localities. No species of Angophora, the comm(ni 

 Apple Tree around Sydney, appears to exist on the part of 

 Monaro under discussion. The bleak conditions also restrict the 

 ferns to a very few species. Casuarina Cunning hamiana Miq. 

 (River Oak), though common on the central parts of the Misr- 

 rurabidgee River, is apparently unable to withstand the rigidity 

 of climatic conditions near Cooma; for, from the information 

 available, it does not appear to ascend above the Miclielago 

 district. Though this tree is so common on the freshwater por- 

 tion of our rivers, it has its limitations on the western watershed 

 both against extreme cold and extreme heat, and flouiishes best 

 on the western slopes and lower mountain-areas. 



Plants around Cooma. 



Most of the plants collected within a few miles of Cooma were 

 growing on gneiss-formation, which may be roughly described as 

 a coarse schist with granitoid structure, suggestive of a crushed 

 or stratified granite, and is a type of rock not ver}' common in 

 tins State. The notes for this paper were taken chiefly in Feb- 

 ruaiy, 1908, and supplemented during a short visit to Kybean 

 early in November. (The name Kybean is pronounced with 

 the accent on the first and last syllables.) The following is a 

 list of plants noticed between Cooma and the Murrumbidgee 

 River about five miles northerly' : —
