FERTILISATION OF THE GOODENIACEJS, 
stages, which are deciduous), and rarely ciliate on the lip. The 
lip of the indusium is shallow, and usually divided into two, or 
sometimes four, by notches. The indusium and stigma are in 
most species of a very dark colour. The stigma rarely grows out 
to project beyond the indusium lips, which is also the case in 
other plants of the order. The plants, with the exception of D. 
diversifolia, DeVr., are always clothed with silky, cottony, woolly, 
stellate or branching hairs on the calyx, and the outside of the 
corolla (except the wings) and sometimes on the stems and leaves. 
The flowers are almost always blue or purple. In the remarks on 
the genus in Flora Australiensis [1] the colour is said to be blue, 
purple, red, white, or rarely yellow. This latter colour I have 
not seen in any fresh specimens (except in the tube), and in dried 
plants it is very difficult to make out the colour. But from an 
analysis of the descriptions in Flora Australiensis, it appears that 
of the 34 species described, 23 are blue or purple, 1 white, and 1 
(D. rosmarinifolia, Schl.) is said to be white, blue or red; while 9 
have no colour mentioned. 
The characteristic features by which they may be recognised 
are the solitary ovules, connate anthers, the auricles, and the 
hairless style and indusium. 
From their dense covering of hairs they have the aspect of 
desert plants, and judging by the number of species collected by 
the Elder Expedition, they are plentiful in the arid interior of 
Australia as compared with other genera of the order. And 
many of the species of other genera occurring there are also 
tomentose. The Census of Australian Plants [2] gives in all 38 
species of the genus, which are distributed as follows : — West 
Australia has 29 species, 26 of which are endemic; South Australia 
5 species, none endemic (this number would probably be much 
higher were the central parts of the colony collected over); 
Victoria has 5 species, none endemic; Tasmania has 1 species 
found elsewhere also; New South Wales has 7 species, 1 being 
confined to the colony; Queensland has 6 species, 2 endemic; 
and North Australia 1 species, o icurring elsewhere also. From 
this it will be seen that the head-quarters of the genus is in West
