height within the growing season. The winter frosts 

 wilted their leaves and blackened their stems, eventually 

 destroying them, the plants growing in their natural environ- 

 ment, though unsheltered, escaping uninjured. 



Two twiners Geltonoplesium cymosum A. Cunn., and 

 Eustrephus latifolius R. Br., find in the canopy and support 

 of the tall shrubs and trees suitable conditions for climbing, 

 the two species, their stems intertwined, occasionally 

 mounting the same tree. Their range is similar, neither 

 advancing far inland, and both extending from Queensland 

 to Victoria. Both species are generically monotypic. An 

 individual specimen, the only one noted on the shore line, 

 of a large fruited Eucalypt, overhangs the watercourse. It 

 is considered by the Government Botanist, Mr. J. H. Maiden, 

 to be an intermediate form between E. pellita P.v.M., and 

 E. resinifera Sm., both of which are exhaustively treated 

 in his "Critical Revision of the Genus Eucalyptus," Vol. in, 

 Part 10. 



Pultencea daphnoides Wendl., a common coastal gully 

 shrub, is occasional among the larger growths near the 

 watercourse. It extends from Port Stephens south to 

 Tasmania, and ascends the Blue Mountains to the eastern 

 slope of King's Tableland. The Christmas Bush, Cerato- 

 petalum gummiferum Sm., is also occasional in this shady 

 situation, but its greater frequency on the open hillside 

 marks its preference for the latter situation. The foliage 

 of this species is an excellent phenological indicator, the 

 leaves responding in a marked degree to seasonal changes. 

 It is confined to New South Wales, is chiefly coastal, and 

 ascends the Blue Mountains to Katoomba. 



The dimorphic leaved Bapanea variabilis Mez, has 

 prickly margined juvenile leaves, which are not maintained 

 in the adult foliage, a physiological metamorphosis whose 

 function is still in the controversial stage. It is here
