CY R. H. CAMBAOE. 697 



Tetratheca ericifolia was found near Coree and Booioomba. 

 It has been noticed, over many years of collecting, that flowers 

 of this species and its variety thijmifolia keep their pinkish 

 colour for years, oi- ver}^ much longer than those of the majority 

 of Australian plants, and it seems evident that these flowers 

 contain some dye of a fixed nature which is probably worth 

 investigating. 



Five species of Pomaderris were seen, distributed over various 

 portions of the Territory. Unless some disinfectant is used in 

 herbaria, the flowers of most plants are attacked by insects, 

 orchids, for instance, being devoured in a very short time; but 

 plants of the genus Pomaderris seem to possess some resisting 

 qualities, as its flowers may remain intact for several years with- 

 out any special care. 



Brachy chiton ])0)>ul7ieiis (Kurrajong) is not common within 

 the Capital Territory, the locality being rather cold for it. There 

 is one fairly large tree, however, on the summit of a quartzite 

 hill within the Capital Cit^ site, and from which the hill has 

 taken its name. This species is a lover of limestone-formation, 

 and in places on the Western Slopes may occupy almost exclu- 

 sively certain areas where there is a considerable outcrop of 

 limestone. It is remarkable, therefore, that it should flourish 

 on this quartzite-hill, the rocks of which contain only a trace of 

 lime, according to Mr. J. C. H. Mingaye, but have a high per- 

 centage of silica, a constituent which this plant does not favour 

 when present in large quantities. A few Kurrajcmgs were 

 noticed at other spots, notably between the Naas Iliver and 

 Gudgenby, in which locality they were chiefly on the north or 

 warm sides of the hills, and by this means were able to grow at 

 higlier altitudes than usual in this latitude, one tree being seen 

 at an elevation of about 2,600 feet above sea-level. 



Viola betonicce/olia and V. hederacea, commonly known as 

 Wild Violets, were seen in many shady nooks throughout the 

 Territory, and the beautiful dark blue flowers of the former were 

 noticed as far up as between the 5,500 and 6,000 feet levels 

 on Bimberi Peak.
