AtalarUia glauca^ known as Wild Lemon, was not plentiful, 

 only one cluster of bushes being noticed. Its vernacular name 

 is in allusion to its sharp spines, and round acid berries, about 

 half an inch in diameter, which somewhat resemble small lemons, 

 though they are really more like limes. The species belongs 

 chiefl}^ to Queensland. 



In many localities throughout the western districts there is a 

 small form of Yarran [Acacia homalophylla) which appears to 

 diflfer in the root from the large trees of this species. Old trees 

 have a system of lateral roots extending all round the base of the 

 trunk, but many of these smaller trees, though erect in the 

 barrel, are found to be supported by one root in a horizontal 

 position, or practically at right angles to the stem. Still no 

 botanical differences could ever be detected between the two 

 forms of Yarran. On looking into the matter near Gilgandra 

 and examining very young trees, it was found that all those 

 which grew with the stem at right angles to the root were 

 suckers. It was further noticed that there was an absence of 

 suckers around a large growing tree, but where one had been 

 cut down, or ringbarked, quite a crop of suckers had sprung up, 

 and in one instance the outermost plant was 27 feet from the 

 parent tree. The observations clearly proved that the felling of 

 the trees caused the growth of many suckers which would in 

 time, if left, form small clumps of trees. In examining the 

 small roots which proceeded from the parent stump, it was noticed 

 that they increased in size immediately beyond the point from 

 which the young plants grew, and just behind this point there
