324: NOTES ON NATIVE FLORA OF NEW SOUTH WALES, VIL, 



other Eiicalypt, it may be said to fairly succumb at Kybean, the 

 moment the full strength of the coastal conditions is encountered. 

 When nearing the sumnnt from the west, it was a curious sight 

 to see the tops of large gum ti'ees of a different species gradually 

 coining into vieNv from the coastal side. These were found to be 

 Eucalyptus fraxiaoides Deane and Maiden, nestling around the 

 heads of the gullies having an eastern aspect, and not one tree of 

 this species was noticed on the exposed western face. Tree-ferns 

 and brush-growihs are said to flourish in the eastern gorges 

 before they have descended a mile. The time at my disposal for 

 investigation was very limited, but it seems clear that the locality 

 presents excellent material for studying the effects of aspect, 

 temperature, shelter, and moisture upon the growth of plants.* 



Hymenanthera dentata var. angustlfolia, laden with green 

 berries which are bluish when ripe, was found growing in a 

 curious, spreading, prickly-looking mass, often covering rocks, 

 and in habit totall}^ unlike H. dentata when seen near the Nepean, 

 Cox's River, or Kangaroo Valley as an erect shrub of several 

 feet. 



A remarkable prostrate form of Dilhoynia ericlfolia was 

 noticed on the granite-formation close to the bank of the Kybean 

 River, at about 3500 feet above sea-le\"el, much of the plant 

 being covered with yellow flowers, while the stems are partially 

 imbedded ia the soil. An exactly similar form has been noticed 

 in two localities near Braidwood, also on granite, at an elevation 

 of slightly over 2000 feet, so that the prostration cannot be 

 attributed solely to sev^ere climatic conditions. At Sydney and 

 on the Blue Mountains, D. ericifolia is a ver}^ common, j^ellow- 

 flowerel, little shrub of a few feet, erect in habit, though often 

 diffuse. 



The plant referred to as Acacia lunata var. (No. 2000) was 

 found near the head of the Tuross River on the conglomerate
