372 BOTANY OF NORTH-EASTERN NEW SOUTH WALES, 



Legumittosce are widely distributed, and are a conspicuous 

 feature in the vegetation in many parts of this region. They 

 are found on all classes of soil, and in rocky situations. The 

 Suborder Pajrilionacece includes some very beautiful flowering 

 trees, shrubs and climbing plants. Amongst the trees Barklya 

 syringifolia F.v.M., with bright yellow flowers, Castanospermum 

 australe A. Cunn., with deep orange-coloured flowers, Daviesia 

 arborea W. Hill, with bright yellow flowers, and Erythrina 

 indica Lam., with scarlet flowers, are a charming sight when in 

 bloom. The two last-named are not nearly as common as the 

 others, and as far as my observations go, only occur in the 

 extreme north. The shrubby species are numerous, and some of 

 the most beautiful and profusely flowering ones belong to the 

 genera Aotus, Daviesia, Dillwynia, Gompholobium, Hovea, 

 Indigofera, Jacksonia, Oxylobium, and Pultencea. One of 

 the most beautiful flowering climbing plants is the "Native 

 Wistaria," Millettia megasperma F.v.M., which I have seen 

 hanging down in most graceful festoons from trees more than 

 fifty feet high, thus showing its large racemes of purple flowers 

 to the greatest advantage. Lonchocarpus blackii Benth., is 

 another singularly effective, tall, woody climbing plant with dark 

 purple flowers borne in large, terminal panicles. Mucuna 

 gigantea DC, is a large twiner with pale greenish -yellow flowers 

 in short, loose corymbs on rather long, pendulous peduncles. 

 There are quite a number of smaller climbing or twining plants 

 producing flowers of various hues which when in bloom have a 

 pleasing effect. The only species of the Suborder Caisalpiniect 

 which attains arboreal dimensions in the North-East is Cassia 

 brewsteri F.v.M. (the other members of this group being either 

 shrubs or climbers) It is an exceedingly ornamental evergreen 

 tree, of which there are two or three well-marked varieties In 

 the dense forests the trunks grow straight with only a few 

 branches near the apex, but in more open country the tree forms 

 a beautiful umbrageous head. In the Suborder Mimosece species 

 of the genus Acacia largely predominate; the Phyllodineai being 

 much more numerous than the Bipinnahv. Many of the former
