Australia, and a close examination of all the species there would 

 doubtless reveal some interesting indications of the line of evolu- 

 tion. One or two such facts came under my notice in working- 

 out some species from that colony. 



I have to thank ]Mr. C. Moore, F.L.S., Director of the Botanical 

 Gardens, and Mr. C. T. Musson, F.L.S., for specimens of several 

 New South Wales Dampieras and other Goodeniads, and through 

 the kindness of Mr. J. H. Maiden, F.L.S., Director of Technical 

 Education, and Mr. J. J. Fletcher, I have been enabled to 

 see and analyse the species of Dampiera collected by the 

 Elder Expedition, and presented to the herbaria of the Techno- 

 logical Museum and the Linnean Society. It is these and some 

 fresh New South Wales species that I propose to treat of in the 

 following notes. 



1. Dampiera Brownii, F.v.M. 



In the young buds the stigma is button-shaped, no indusium 

 being visible, but a slight fosse shows across the top (Fig. 1). In 

 the next stage the indusium shows as a thin wall of irregular 

 height all round, but with a notch at each end, and at right 

 angles to the line of the stigmatic groove. During these stages 

 the whole pistil is green. At the next stage the indusium is 

 grown up level all round (Fig. 2), except at the notches, and both 

 indusium and stigma are coloured deep purple, but the style 

 remains green; the purple colour appears first on the stigma, and 

 spreads afterwards to the indusium. The style still continues to 

 elongate and passes into the auricle, the top of the style bending 

 over so as to bring the opening over the junction of the two 

 auricles. During this period the indusium closes by the oj)posite 

 segments (divided by the notches) approaching, and at last there 

 is only a small circular opening. The indusium has been packed 

 with pollen by growing up through the anthers while the mouth 

 was wide open, and when the stigma begins its outgrowth at this 

 period it forces the pollen out in a small worm-like string, which 

 when exposed to the air falls in powder into the auricles, where it 

 lies. An insect forcing its way into the tube of the flower presses
