in Heuffel's Herbar vorliegt; dass also Heuffel diese Art niemals- 

 selbst gefunden habe, sondern dass sich sein Citat einzig und allein au! 

 die ältere Angabe Rochel's stütze. Bezüglich Rochel's Saxifraga 

 biflora untersuchte nun Verf. die von Rochel selbst am Szarkö ge- 

 sammelten Exemplare und fand^, dass diese Pflanze nichts anderes sei, 

 als Saxifraga oppositlfolia L. Da nun die Angabe des Vorkommens der 

 fraglichen Pflanze auf der Alpe Szarkö in Südungarn als eine für 

 Ungarn alleinstehende ist, so ist die westliche Saxifraga biflora AU., 

 deren Vorkommen in Ungarn schon aus pflanzengr.ographischen 

 Gründen nicht wahrscheinlich war, aus der Flora Ungarns zu 

 streichen. Kümmerle (Budapest).

Gambage, R. H., Notes on the native fiora ofNew South 

 Wales. Part IV. The occurrence of Casiiarlna strlcta 

 Ait, , on the Nerrabeen Shales. (Proceedings of the 

 Linnean Society of New South Wales. Vol. XXX. 1905. 

 Part 3. No. 119. p. 376-391. Plates XII- XIII.) 



Casuarina striata Ait. is a common tree on many of the hills 

 throughout the western districts ofNew South Wales, and is re- 

 corded from various localities in Victoria, South Australia, 

 Western Australia and Tasmania, thus growing under many 

 different conditions of climate. This and its wide distribution suggest 

 that it is a species of great antiquity, probably antedating the time 

 when Tasmania ceased to be connected with the mainland. The 

 author's discovery of this species near Newport on the Narrabeen 

 Shales is the most northern locality recorded on the east coast. The 

 Narrabeen beds consist of shales and sandstone of early Triassic age, 

 which owing to subsidence of the central part of the coal basin west 

 of Sydney, are found to dip to nearly 900 feet below sea-level on the 

 northern shore of Port Jackson, reappearing on the coast north-east 

 of Otford, nearly 30 miles to the south. At these two points (N arr a- 

 been and Otford) these shales are exposed to a greater exient Ihan in 

 any other part of their area. C. strlcta has been recorded from Otford, 

 as well as (by the author) from Newport, although not common else- 

 where on the coast ofNew South Wales except perhaps in the ex- 

 treme south. It is somewhat difficult to account for the preference of 

 this species for the Narrabeen shales; the author suggests that „if it 

 could be shown that the Narrabeen shales in prehistoric times had ex- 

 tended eastward from the present coast-line and were clothed with 

 Vegetation, it would seem quite possible that this Casuarina may have 

 formed part of its flora; and these isolated patches now on the present 

 coast are the remnants of this particular species, the greater part of 

 which has been destroyed in the intermediate localities by the alteration 

 of the shore-line". 



Evidence is then adduced to show that the coast-line of New 

 South Wales has been cut off as the result of sinking; the fossil 

 forms of Casuarina, found in Australia, are discussed in the same 

 relation. F. E. Fritsch.
