576 NOTES ON THE NATIVE FLORA OF NEW SOUTH WALES, Vlii., 



Gramine^ : Arundo Phragmites Dod., (in Colong Creek), 

 Poa ccespitosa Forst., (tussocks, in Barrallier's Pass). 



FiLiCES : Gleichenia dicarpa R.Br., (Braid or Bead Fern), 

 Todea harhara, Alsojjhila australis (Tree-Fern), Adiantum 

 Aethiopicum (Maiden-Hair Fern), Hypolepis tenuifolia 

 Bernh., Cheilanthes tenuifolia, Pteris aquilina (Bracken), 

 Blechnuni cartilagineum, Doodia aspera, Asplenium flahelli- 

 folium, Polystichuni aculeatum (Aspidium aculeatttm ; on top 

 of Mount Werong), Dryopteris tenera (R.Br.) C.Chr., {Aspi- 

 dium tenerum Spreng. ; common from 3000 to 3600 feet). 



An interesting little Hibbertia(No 2259), which may be a form 

 of H. serpyllifolia, or possibly a new species, was found on the 

 Big Plain, at an altitude of about 3,800 feet. The plants were 

 only about six inches high, having narrow linear leaves, under 

 two lines long, with slightly recurved margins, and faintly ciliate 

 on the edges. On 4th October, 1909, no flowers were procurable, 

 and all the very young buds, just forming, appeai'ed to be 

 terminal. 



Sterculia diver sifolia (Currajong) was not noticed between 

 Colong and Mount Wei'ong, the elevation near the track probably 

 being too great for it. On the belt of limestone at lower levels, 

 it is a conspicuous tree, especially at Church Creek, a tributary 

 of the Kowmung. This is a species which flourishes very much 

 better on soils derived from basic rather than siliceous rocks, and 

 distinctly seems to prefer a soil having a high percentage of lime. 

 It is, therefore, rare on sandstone, fairly common on basalt and 

 allied rocks, and plentiful on limestone. In localities south of 

 Sydney, it is rarely found at altitudes exceeding 2,200 feet, as it 

 avoids the cold country, and neither this species nor the genus is 

 represented in Tasmania. 



A new species of Zieria was found near Mount Werong, which 

 has since been described as Z. rohusta Maiden and Betche (these 

 Proceedings, 1910, p. 788). Just east of Mount Werong, is a 

 headland locally known as South Head, to the west of the Big 

 Plain (3,800 feet) and overlooking j^art of Ruby Creek gorge.
