Part v. Bowral to the Wombeyan Caves. 



(Plates xxxiv.-xxxv.) 



The notes used in the preparation of this paper were taken at 

 the end of September, 1905, during a visit made to the Caves in 

 company with Messrs. J. H. Maiden, F.L.S., and E. C. Andrews, 

 B.A. I have to acknowledge assistance from the former in 

 identifying plants, and from both in collecting specimens. Mr. 

 Maiden also placed his notebook at my disposal to augment my 

 own if necessary. 



The Wombeyan Caves are situated 42 miles by road in a 

 general westerly direction from Bowral, which is on the Great 

 Southern Railway Line. The country around Bowral ranges 

 from about 2200 to 2800 feet above sea-level, with an annual 

 rainfall of 39 inches; and may be regarded as part of the table- 

 land which extends across in the direction of Goulburn and 

 Braidwood. The road towards Wombeyan rises slightly for some 

 15-20 miles, but near the 25-mile post a steep but most picturesque 

 descent is commenced into the valley of the Wollondilly River, 

 which is reached by a winding road in seven miles. The ascent on 

 the western side of the river is made in another seven miles, after 

 which there remains a descent of three miles to the Caves. 



The geological formation of the valley in which Bowral is 

 situated consists chiefly of Wianamatta Shale enriched from sur- 

 rounding basaltic hills; while towards Mittagong stands the well 

 known syenite hill which bears the local name of The Gib, 

 (abbreviation of Gibraltar) and from which the rock known to the
