Part iv. The Occurrence of Casuarina stuicta Ait., on 



THE NaRRABEEN ShALES. 



(Plates xii.-xiii.) 



The occurrence of C asuarina stricta Ait. (C quadrivalviG 

 Labill.) near Sydney is a matter of considerable interest both 

 from a geological and botanical standpoint. 



This species is often known as She-oak and sometimes as 

 Mountain Oak; and although it cannot be said to grow into large 

 trees, being usually about 20 feet high, its shapely rounded head 

 and pendulous habit render it a very graceful and picturesque 

 member of our native flora. It is a common tree on many of the 

 hills throughout the western districts of New South Wales, and 

 is recorded from various localities in Victoria, South Australia, 

 Western Australia and Tasmania. It may be seen from several 

 points on the railway line between Albury and Melbourne, 

 between Melbourne and Adelaide, and also between Launceston 

 and Hobart, being common on the igneous formation around the 

 former, especially near The Gorge. In my ' Notes on the Botany 

 of the Interior of New South Wales' (these Proceedings 1900-1902) 

 it has been recorded under the name of C. quadrivalvis Labill., 

 from many localities extending from Cobar, Nymagee, Mount 

 Hope, Condobolin, Trundle, Forbes, Wyalong, Cootamundra to 

 Junee; and by others from the Mudgee and Goulburn River dis- 

 tricts south-westerly. It occurs at Mount McDonald (on granite), 

 Wagga, Tumut and Gundagai, being formerly very conspicuous 

 on a hill east of Coolac. It has been recorded from South-eastern 

 New South Wales; and specimens in the National Herbarium,,
