having large, tuberous roots. Hoya aitstralis B.Br., may often 

 be seen cultivated in verandahs and in bush houses for the sake 

 of its waxy flowers which are produced very freely during the 

 summer months. Several exotic species of this Order have 

 become acclimatised in different parts of this area, but they do 

 not appear to be spreading much. Logania jloribunda R.Br., is 

 the only shrubby species of Loganiaccce in the North-East, and 

 in early spring produces a profusion of small, white flowers. 

 The other representatives of this Order are dwarf herbs 

 with white flowers. Gentianece are not numerous in species, 

 but grow over an extensive area. One species of Villarsia 

 and three of Limnanthemum are aquatic or marsh plants with 

 yellow or white flowers. The other two species of Sebcea and 

 Erythrcea are used for stomachic and allied complaints by the 

 settlers. With one exception Boraginece consist of herbs 

 or undershrubs widely distributed, but nowhere plentifully. 

 Ehretia acuminata R.Br., attains sometimes a height of thirty or 

 more feet, and is one of the few Australian deciduous trees. 

 There are two forms, the difference being principally in the 

 leaves and flowers. In the typical form the leaves are serrate 

 with callous teeth, the small white flowers crowded in terminal 

 panicles, and the globular fruit usually containing four seeds. 

 The most showy flowering plants of the C onvolvulacece are the 

 different species of Ipomcea. I. palmata Forsk., /. hederacea Jacq., 

 and /. peltata Choisy, are tall twiners, and often ascend to the 

 tops of trees. When in bloom they are a charming sight, the 

 colour of the flowers being white, pink, purple, or blue. At 

 Byron Bay I saw /. pea-caprw Roth., covering large areas of sand 

 with its prostrate trailing stems. It produces rather large, pink 

 flowers, and the roots, after being cooked, are eaten by the 

 aborigines. Four exotic species have become acclimatised, and 

 when in flower add considerably to the display of the floral 

 wealth of this region. - Solanetv are well represented, and quite a 

 number of exotic species have established themselves on this 

 area. Some of these are of an undesirable, and others of a 

 poisonous nature. Amongst the indigenous species, Solauum
