366 FERTILISATION OF THE GOODENIACE^E , 



the indusium and would so have a chance of reaching the stigma, 

 even if that organ did not grow out. It is remarkable, however, 

 that in the same plant some flowers should be resupinate and 

 others in the ordinar}^ position. So far as I know of the other 

 genera only Leschenaultia has resupinate flowers. 



2. Dampieea stricta, R.Br. 



This species on the whole resembles D. Brownii in its mechanism, 

 but with some minor differences. It grows in patches in swamp}^ 

 ground, and flowers very freely, so that the masses are ver}^ 

 conspicuous. The colour is bright blue with a yellow eye. The 

 indusium has four notches (Fig. 6), and closes more completely 

 than in the last species (Fig. 7); the edges are not even, but 

 slightly ragged, and the shoulder of the indusium is papillose, as 

 shown in the figure. The auricles resemble those of D. Broiimii, 

 but have a fringe of sticky crimson hairs along the posterior 

 margin (Fig, 8) which are generally longer on the left-hand lobe 

 (looking from behind the flower). In this it resembles D. erio- 

 cephcda. Guiding ridges are present in the tube of the* corolla, 

 which is 3^ellowish. The stem, calyx and centre of the outside of 

 the corolla-lobes are hairy, the hairs being either stellate or 

 branching. In the latter case they are very curious in form (Fig. 

 9). I am at a loss to imagine what can be the function of the 

 trichomes on the edge of the margin, unless they are to exclude 

 small creeping insects, or to prevent moisture from gaining access 

 to the pollen, as mentioned later on. The}^ certainly do not keej^ 

 Thrips out. The stigma rarely grows out level with the mouth 

 of the cup; the auricles are usually full of powdery pollen, and 

 the style and indusium evenly coated with it. The flowers spread 

 out in a horizontal plane. The process of fertilisation is as in 

 the last species so far as I can see — that is to sa}^, usually self- 

 fertilisation obtains. 



3. Dampiera linearis, R.Br. 



Of this species I have examined only dried specimens. The 

 calyx and corolla are covered with hairs resembling those of D.
