8 A GLANCE AT THE FLORA OP MOUNT WILSON, 



Dipodium punctatum (R. Br.), Gastrodia sesamoides (R. Br.), 

 Microtis porrifolia (Spreng.), C'hiloglottis diphylla (R. Br.), and 

 Thelymitra venosa (R. Br.), the last of which was in full flower. 

 Mr. J. D. Cox informed me that he had noticed rather earlier 

 several species of Diuris, Ccdadenia etc., etc. (1). Dianella cmrulea 

 (Sims.), Ccesia jjarvijloy'a (R. Br.), Thysannttcs tuberosus (JR,. Br.), 

 Geitonojylesium cymosum (A. Cunn.), Sowerbcea juncea (Sm.), 

 and Stypandra ccesjntosa (R. Br.), were the only plants of the Lily 

 family which I observed. The following species also may be 

 enumerated, lonidiurn fioributidxim (Walp.), of the Violacese, 

 Tracliymene ericoides (Sieb.) and T. Billardieri (F. v. M.) of the 

 Umbelliferse, Lobelia gibbosa (Labill.) of the Campanulacece, 

 Mitrasacme pilosa (Labill.), of the Loganiacete, »Sebcea ovata 

 (R. Br.) of the Gentianefe, Pomaderris ledifolia (A. Cunn.) of the 

 RhamnejB, and several species of Hibbertia of the Dilleniaceae. 

 The composites are numerous, but the most remarkable wei'e 

 Cassinia denticulata (R. Br.), C. aurea (R. Br.), Humea eleyans 

 (Sm.), Senecio australis (Willd.), and Helichrysum elalum (A. 

 Cunn.). The native grasses did not appear to be abundant, and 

 the only species which I collected were Microlcena stipoides (R.Br.), 

 Anisopogon avenaceus (R. Br), Cinna ovata (Kunth.), Amp)hi2)ogon 

 strictus (R. Br.), Danthonia semiannularis (R. Br.), and Poa 

 ccesjntosa (Forst.). Not far from the Road, I saw Gleichenia 

 circinata (Sw.), and the Lycopods Lycopodium dens^iin (Labill.), 

 and Selaginella tdiginosa (Spreng.), but these were not so fine as 

 some I have found in the Manly swamps. Before I pass away 

 from the Hawkesbury Sandstone, two species of Casuarina should 

 be noticed, C. nana (Sieb.), and C. distyla (Vent.), both dwarfed 

 plants, and also a Frenela, which Bai'on von Mueller considers a 

 diminutive form of F. MupJleri (Parlat.), a pine found near 

 Sydney and plentiful on the banks of George's River. 



As we reach the foot of Mount Wilson about 300 or 400 feet 

 below the summit or table-land, the character of the vegetation 



(1) Mr. J D. Cox has lately sent me specimens of Dendrobium strlolatum, 

 Prasophyllumfimhriatum, PterosUjlis parvifiora, P. peduncidata, P. nutans, 

 Cryptostylis erecta, Acianthus fornicatus.
