the Others, and all the rest of the process is similar. The out- 

 grown stigma is remarkable for its large size. In this and the 

 other species, as indeed in most of the order, there are quantities 

 of light stiff hairs on the style and outer sides of the cup. Their 

 jHirpose is probably to prevent small insects getting at the pollen 

 by a path which would not ensure the placing of pollen on the 

 stigma. The whole of this plant is slightly hairy, and as it is a 

 prostrate plant, it is perhaps for the same purpose that it is hairy.

 The flowers are less flattened than in Sccevola, and assume a 

 bell-shape, slit down one side. The piocess of pollen-packing is 

 the same. The hairs on the lip of the indusium are remarkably 

 few, and very thick and strong as compared with any other member 

 of the order which I have seen (Fig. 14, n). They cannot act as a 

 brush in taking the pollen out of the anthers, but they bend over 

 the closed mouth of the indusium and form a grille, through which 

 the pollen is .strained (Fig. 14, b). The cup is hairy outside (Fig. 

 14) and these hairs are also much stronger ; they are most plenti- 

 ful on the lower side ; pollen is frequently entangled in them. 

 There are usually a number of small intensely black spots on the 

 outside of the indusium, which may be a fungoid disease. The 

 stigma grows out very largely (Fig. 15), and bends over at the 

 corners (Figs. 16 and 17), a featui-e found in Velleya and at least 

 in one Goodenia. There is no scent; the flowers are greenish, and 

 secrete much nectar. The plants bear fruit very freely. 



5. Brunonia australis, Sm. 



In this species I met with a number of unusual features, which 

 perhaps might have been expected considering the numerous 

 affinities of the plant with orders outside the Goodeniaceo}. R. 

 Brown advocated making a separate order of it (11), pointing out 

 its many features of resemblance and diflference when compared 

 with the orders Compositce, Goodeniacece, and Campamdacece, and 

 concluding that its proper place in the natural system was betv/een 

 Compositce and Goodeniacece. He also speculates on the origin of
