is probably old, considering its wide distribution, and if repre- 

 sentatives had been growing in this vicinity, at the time of the 

 Eastern Australian uplift in late Tertiary time,* which seems 

 quite possible, some plants may have survived, during the gradual 

 upheaval, and their descendants, on finding the new conditions 

 too cold, would gradually have become restricted to the warmer 

 and more sheltered nooks where the geological formation was 

 favourable to their growth, and would, thereby, come under the 

 heading of relics or stranded plants. A difficulty about accept- 

 ing this explanation is that this Oak is a warmth-loving species, 

 and, at an elevation of 2,000 feet, would have found it difficult 

 to survive the Pleistocene glacial period which is generally re- 

 garded as of subsequent date to the uplift that formed the pre- 

 sent mountains. The fact is clear, however, that these particular 

 Oak trees are now growing near the Molonglo River, and although 

 they certainl}^ appear to be stranded plants, the process by which 

 they reached this spot must remain unsolved, at least for the 

 present. 



Grevillea juniperina is one of the most attractive shrubs 

 within the Federal Territory, chiefly because of its beautiful, 

 red, spider-like flowers. It was noticed on the right bank of the 

 Murrumbidgee near its junction with the Cotter, growing as 

 thick spreading bushes up to 10 feet high (Plate Ixxii.). It was 

 flowering in November, and among the birds, which were evi- 

 dently after its honey, were the Leatherheads {Tropido7'hy7ichus 

 corniculatus). At Mongarlowe, near Braidwood, this species 

 was seen in November, 1908, with yellow, as well as red flowers, 

 and in several cases both colours were noticed on the same plant. 

 The feature has been observed by others. 



Batiksia marginata (Honeysuckle) was seen in many portions 



of the Capital Territory, ascending to an elevation of 4,000 feet, 



and occurring chiefly in the granite or somewhat siliceous areas. 



The trees appear toreach greater dimensions than do those of 



this species in the Sydney district, and examples were seen with
