64 The South Austi'alian Naturalist. 



Passing through Belair (13| miles) we again meet with the 

 Red Gnm at 14^ miles, where, in the National Park, they have 

 grown into very big trees. The bark of these trees here takes 

 on a very drab appearance, being of the greenish-grey shade 

 characteristic of this species. The altitude is now about 1,100 

 feet above sea-level, and the character of the flora undergoes a 

 change. Xt this point another range of hills is met with. For 

 a mile or more the Red Gum is plentiful along the gullj^ through 

 which the railway line runs. It is associated here with other 

 light, smooth-barked gums, but at 16 miles they give place to 

 Stringybarks. Between this point and Mount Lofty very little 

 of the Red Gum is seen from the railway, but no doubt there are 

 trees to be found in the moister positions. 

 2. E. leucoxylon. Yellow Gum. 



The Yellow Gum prefers the liills, and I doubt whether 

 there were any trees of this species growing on the Adelaide 

 Plains in the early days. The first of these are to be seen as the 

 first tunnel is negotiated. Along the tunnel hill the Yellow Gum 

 is found near to and on the top. At about 8J miles, we look 

 west down the gully in which grow the Red Gums, and on the 

 hillside to the right grow the Red, Box, and Yellow Gums. After 

 passing through the second tunnel the next Yellow Gums are 

 seen, and then again close to Blackwood, just before entering 

 the third tunnel. At the Blackwood station there are some fine 

 specimens of this tree ; the trunk is streaked with a dark-brown 

 bark near the base, but is of a lighter brown further up. A very 

 light, white-grey bark alternates in strips with the shades of 

 brown. None of the greenish colour of the Red Gum is observed 

 in the Yellow Gum. 



Leaving Blackwood (11^ miles) and on to 13 miles, not much 

 is seen of this particular species, but there is a mixture of Yellow 

 and Red Gums just before Belair is reached, on both sides of the 

 line. On the left side there is a group near the station, and 

 they are trees of 40 to 50 feet high; the bark at the base on 

 some of them is very dark for at least six feet up the trunk, 

 above that it is clean whitish-grey, streaked with light broAvn. 



Passing Belair an ironstone ridge is traversed before enter- 

 ing the next range of hills. Along this ridge some Yellow Gums 

 are found, and most of them are attacked by the Hanging Mistle- 

 toe {Loranfhus pendulus). These gums here are not at all large, 

 sometimes they grow in small clumps, about six small trunks 

 arising from the same underground base. One Yellow Gum, 

 about 30 feet high, witli the bark near the base dark and rough 

 grey -brown and whitish, with the Mistletoe (LorantJuis pendu- 

 lus) on it, is to be seen in National Park, near the Belair station.
