The leaves at first sight are reminiscent of one of 
our fairly common Santalaeeous trees, Exocarpus lati- 
f alius, sometimes called Broad leaved (False) Sandal- 
wood. 
The hair-tufts on the perianth segments of the male 
flowers are to be found in a number of different genera 
of Santalaceae, but differ somewhat in degree of devel- 
opment and position. in II nislouiu queenslaudiae the 
hairs appear to pass through a narrow slit between the 
two upper or outer and larger cells of the anther behind 
which they arise and just project on the opposite face. 
When young buds are opened, the hairs are wedged so 
firmly in the anthers that they occasionally tear away 
from the attachment to the perianth and appear as a 
tuft of hairs on the back of the anther. In the partially 
opened flowers, however, if a perianth segment is forced 
open, the hairs at first cause the opposed stamen to bend 
outwards but finally slip out of the slit in the anther 
thus permitting the stamen to return to its former posi- 
tion. The function of the hair-tufts is not clear although 
it seems possible that they may play some part in ejee 
tion of the pollen by “springing” the stamens as the 
bud opens. 
As overseas species of Hcnslowia have been variously 
described as root-parasites or parasitic on the branches 
of trees in the manner of the Mistletoes, the root system 
of a plant growing at Alt. Edith was examined, admit- 
tedly in a rather primitive fashion, but no definite evid- 
ence of parasitism was found. A single graft between 
two adjacent roots, each about half an inch in daimeter, 
was observed but this may occur occasionally in almost 
any plant where the/ roots have been accidentally pressed 
against one another.
