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 opposite 
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
