 Botany.— (a) Systematic. — This is quite an interior species 

 of the continent and extends from the western edge of the 

 coastal table-land right across to Western Australia. This 

 species has many 'points of resemblance to M. nodosa, but 

 apart from its habitat, is more readily to be distinguished 

 from that species by its terete leaves with their numerous 

 and conspicuous oil glands. It is also a more slender shrub 

 than M. nodosa. It is well described in Bentham's Flora 

 Australiensis, Vol. in., p. 150, where also its synonomy 

 is given. The material, however, examined by us shows 

 perhaps a little more variation than mentioned by that 

 author. For instance, some specimens from the interior 

 of New South Wales and Hog Bay, Kangaroo Island, have 

 the claw of the staminal column at least twice the 

 length of the petals, which latter organs, not described by 

 Bentham, are found to be scarious, ribbed, and measure 

 about 2 mm. or the length of the calyx, also the specimens 

 from the dry interior are invariably silky pubescent, those 

 from nearer the coastal plateau being glabrous. The 

 material upon which this research is based, was obtained 

 from Wyalong, New South Wales.
