OF THE INTERIOR OF WESTERN AUSTRALIA. 249 
Amaranthacee. 
Fairly well represented in the desert by 4 genera sharing 14 
species—the South-west having 47 species referred to 8 genera. 
2 of the desert species are endemic; 3 are South-western ; 6 are 
extratropical or tropical and extratropical Australian, 5 including 
and 1 excluding the South-west; 2 are tropical Australian forms 
which penetrate into the northern part of the desert; and 1 
ranges from the North-west tropics through the northern part of 
the West Australian desert into the Larapintine region of South 
Australia. 
Chenopodiaceae. 
In the South-west there are 12 genera, according to Mueller’s 
classification, and 61 species. 8 of these genera, with 31 species, 
are found in the desert. Only 2 of the species are endemic in 
the West Australian desert, 2 more are restricted to the deserts 
of West and South Australia, and 1 species is Larapintine; 14 
are extratropical or tropical and extratropical Australian, inclu- 
ding the South-west; and 8 have the same distribution, except 
that they are not known from the South-west corner. Salsola 
Kali has world-wide distribution. 
Loranthacee. 
All the South-western species of Loranthus reach the desert, 
there being only 5 South-western and North-west tropical 
species altogether, whereas 8 species are now known from the 
desert. One species is endemic in the West Australian desert, 
and two are shared between it and the desert of South Australia, 
while a third extends into the West Australian desert from the 
south of South Australia. The 4 remaining are distributed over 
tropical and extratropical Australia, and all the 4, except 1, are 
found in the South-west corner. 
Proteacee. 
Bearing in mind the richness of this order in the South-west 
corner of the continent, it is very poorly represented in the 
desert. From Mueller’s Census we learn that there are no less 
than 397 species of West Australian Proteaces, referred to 15 
genera, and nearly all of them are exclusively West Australian, 
11 of these genera occur in the desert, but only 47 species. 12 
of the species are endemic in the West Australian desert; 3 are 
shared between the West and South Australian deserts, and 1 of
