luteijiora. The indusium is not two-lipped but continuous all 
round, and shows an approach to ciliation (Fig. 11). The stigma, 
in perfect flowers, is very near the mouth as shown in the figure. 
As I had flowers only to examine, I do not know how it is placed in 
the bud. The auricle (Fig. 1 2) shows little differentiation, the wing 
which forms it being merely folded inwards, and slightly hollowed 
for the reception of the indusium. It is not coloured. In the 
imperfect ciliation, it forms a link between Sccevola and Goodenia 
on the one hand, and the more complicated arrangements of the 
typical Dampieras on the other. The margin indeed resembles 
that of Sccevola ovalifolia in early bud, where the cilia at first- 
exist as a thin membrane continuous all round the indusium, 
which afterwards breaks up into separate cilia. The plant is 
obviously well adapted for insect-fertilisation, as a pollen-coated 
insect, pressing into the tube, could scarcely fail to leave pollen on 
the stigma. 
4. Dampiera sp 1 
An unnamed species from Yeodamie, W.A., in the Techno- 
logical Museum Herbarium, has the auricle more developed (Fig. 
13) and coloured, but not deeply; the indusium also is pale in 
tint, and, as in D. linearis, there is an approach to ciliation of 
the margin of the indusium. This species is closely covered with 
cottony hairs. Like the last, it is probably insect-fertilised. 
5. Dampiera luteiflora, F.v.M. 
I have seen only dried specimens. The calyx, corolla and 
stems are thickly covered with yellow hairs, mostly branching 
(Fig. 14). The indusium is very short and two-lipped (Fig. 16). 
I did not see an outgrown stigma, or even one level with the 
mouth, but the amount of material at my disposal was so small 
that it cannot be said certainly that it does not do so. But from 
the shallowness of the indusium, this would be a matter of less 
importance, and would not, as in some other species, be any 
impediment to the deposit of pollen on the stigma by insect 
agency. The shoulder of the indusium is papillose as in D. 
stricta. The auricle (Fig. 15) is rather simple. The indusium is 
invariably full of pollen, and it is present also in the auricles.
