HENSLOWIA — AN ADDITION TO THE AUSTRALIAN 
GENERA OF SANTALACEAE 
By L. S. SMITH 
In his account of the family Santalaceae, in Engler- 
Prantl Natmi. Pflanzenfam. 2 A till. Band 16b. 52-91 
(11)85) , Bilger recorded eight genera from Australia. 
Representative of seven of these occur in Queensland 
and are dealt with by F. M. Bailey in Queensl. Flora V. 
1383-1:191 (1902), the remaining genus being known only 
from New South Wales and Victoria. Henslowia Blume, 
here recorded for the first time from Australia, raises 
the number of Queensland genera to eight and makes a 
total of nine for the whole continent. 
The tribe Os.vrideae, to which H endow) a belongs, 
includes four other genera represented in Queensland, 
namely Choretrum, Leptomcria, tantalum and Eucarya. 
From these Henslowia may be readily distinguished by 
its lall-climbing habit and apparently dioecious nature. 
The oilier genera comprise species which are shrubs or 
trees and appear to have bisexual flowers. 
Bilger states that some 30 species of Henslowia have 
been described and suggests that when better material is 
available fewer species will be recognised. They occur 
from s-outh-eastern Asia through the intervening islands 
to New Guinea, and are found mostly at higher eleva- 
tions. The Queensland specimens are here treated as 
belonging to a new species.
