TOPOGRAPHICAL, ECOLOGICAL, AND TAXONOMIC NOTES. 305 



"It is found all over the island climbing the highest trees.'* 

 At Kurnell, near the landing place of Oaptain Oook, it was 

 noted climbing trees of Banksia integrifolia, and this is 

 doubtless the source from which Banks and Solander col- 

 lected their specimens, a sheet of which is now incorporated 

 in the National Herbarium collection. It has not, so far 

 as I can ascertain, been recorded south of Port Jackson, 

 but we have specimens in the National Herbarium collected 

 by Mr. A. H. S. Lucas at Jervis Bay, 7, 1899, and by Mr. 

 R. H. Oambage at Ulladulla, No. 4174, 12, 1915. 



Associated with these trailers was the prostrate herbace- 

 ous Hibiscus trionum L., the "Bladder Hibiscus" of 

 Europe. Its flowers are short lived, opening for a few 

 hours only. It was not seen elsewhere on the shoreline, 

 but its occurrence in the vicinity of the beach is not unusual. 

 The indigenous vegetation, with the exception of a few 

 scattered trees of Banksia integrifola, several of which 

 occupy positions on the extreme verge of the bluff, has been 

 removed from the top of the headland and the ground turfed 

 with "Oouch," which creeps down the slopes of the over- 

 lying Narrabeen Shale until it reaches the rocky escarpment 

 at the base, where it finds its associates of the dune Sporo- 

 bolus virginicus and Zoysia pungens, fringing the rock 

 benches. 



Beyond the bluff the beach narrows, the dune embank- 

 ment rising abruptly from the strand, its verge indifferently 

 protected by the remnant of the native flora. On the 

 northern slopes of Long Reef point, isolated specimens of 

 Banksia integrifolia find a somewhat insecure foothold on 

 the ridges, the trees dwarfing as they reach the line of 

 exposure on the ocean front. [The winds most injurious 

 to the vegetation on the shoreline come from the south, 

 and the northern slopes of a promontory or headland are 

 more or less protected from its visitation].
