Introduced Trees and Shrubs. 
By the late Dr. R. H. Pulleine, W. H. Bagot, 
and H. Greaves 
JHE planting of trees and shrubs introduced from other 
countries is not strictly in accord with the preservation of the 
natural flora, which must always be a primary function of a 
national park. Nevertheless, the grouping of familiar flowering 
and other shady deciduous trees, such as those surrounding the 
Long Gully Oval, adds to the amenities of the park as a place 
of public enjoyment. Where such planting has been confined to 
the borders of watercourses and grassy flats, it has proved most 
successful, both in the welfare of the individual tree and from 
a landscape aspect. Introduced verdure does not merge very 
well with the native in colour or texture and. beautiful as it is, 
often its contrast is not always favourable to its surroundings, 
rhe most recent systematic planting was that undertaken at the 
instance and the expense of the late Mr. Francis H. Snow in 
1922 near the top of Spark’s Gully. Here are massed along the 
watercourse a large number of the Japanese Flowering Cherry 
among other trees such as the Birch, the Japanese Maple, and 
the Liquidambar. September and October are the blossoming 
months, and from April to May the autumnal tints are to be seen 
at their brightest. Lower down the same gully are effective
