OF THE INTERIOR OF WESTERN AUSTRALIA. 247 
Umbellifere. 
This is an order but poorly represented in the desert by 10 
species referred to 6 genera. Western Australia has 8 genera, 
containing between them 52 species. Of the desert species 5 
are restrictedly South-western, aud 1 extends from the South- 
west into South Australia south of 30?; 1 is extratropical 
Australian, including the South-west; 2 are endemic in the 
desert; while the 10th, known only from the northern and 
eastern outskirts of the desert, is an extratropical Australian 
species not found in the South-west corner. 
Composite. 
There are 47 genera of Composite in Western Australia and 
211 species. Of these genera 32 have desert representatives, to 
the number of 97 in all, but only 12 of the species are endemic 
in the desert; while, strangely enough, no more than 11 are 
restrictedly West Australian forms. 35 of the remainder are 
extratropical or tropical and extratropical Australian including 
the South-west; 14 have the same distribution, except that they 
are absent from the South-west; 12 range from the South-west 
into South Australia; 4 are West and South Australian desert 
species, 1 of them extending into Western New South Wales; 
and 5 range from the West Australian desert into the Lara- 
pintine region of South Australia, one of them (Pluchea dentex) 
reaching Queensland. The remainder are introductions or 
species of world-wide distribution. 
Stylidee. 
This predominantly South-western order is poorly represented 
in the desert. The two West Australian genera have in all 70 
species. Both genera occur in the desert: 1 (Levenhookia) 
represented by a single, the other (Stylidium) by 5 species. All 
the desert species are South-western, except one which is 
endemic. 
Goodeniacee. 
6 of the 11 genera of this predominantly South-western order 
are found in the desert, and 42 species as compared with the 
130 South-western ones. 11 of the species are endemic; 2 are 
common to the West and South Australian deserts; 1 is a Lara- 
pintine species; 15 are South-western ; 2 are tropical and extra- 
tropical Australian, including the South-west; 7 are tropical and
