248 MR. 8. MOORE ON THE FLORA 
extratropical Australian, but excluded from the South-west 
corner; while 4 are natives of the North-west tropies, whence 
2 of them extend into the Larapintine region of South Australia. 
Epacridee. 
An order very sparsely represented in the desert. 11 genera 
(as understood by Mueller), with 152 species between them, are 
known from the South-west. This number dwindles in the desert 
to 3 genera and 4 species! One of the 4 is endemic; the rest 
are South-western forms. 
Loganiacee. 
This order is represented in the desert solely by the predomi- 
nantly West Australian genus Logania, of which three species 
have been met with in the desert, all of them south of 30°. 
One of these is South-western; the other two range eastward 
into South Australia, one of them reaching New Scuth Wales 
and Victoria. 
Solanaceae. 
7 of the 8 South-western genera of this order inhabit 
the desert, where they are represented by 18 species—there 
being 27 West Australian species in all. Solanum has 12 desert 
representatives, as contrasted with only 9 in the South-west. 
1 of the 12 is endemic; only 1 is restrictedly West Australian 
including the South-west; 2 are West and South Australian 
desert species; 2 are extratropical Australian, including the 
South-west; and 6, while extratropical Australian, are absent 
from the South-west corner. 
Myoporinee. 
This order, which is somewhat better represented in the West 
Australian than in the other Colonies, appears in strong force in 
the desert, where all the 3 Australian genera are found and 35 
species. Of these no less than 15 are endemic in the desert of 
West Australia; 1 is restricted to the West and South Australian 
deserts ; 2 are Larapintine; 5 are South-western ; 4 extratropical 
or tropical and extratropical Australian, including the South- 
west; and 7 the same, but excluding the South-west corner; 
while one is a North-west tropical species which advances into 
the desert north of 30* only.
