Zieria Icevigata Sm.,(2), Wentworth Falls to west of Eskbank; 

 Z. pilosa Rudge, Glenbrook, Springwood, Linden; Z. involucrata 

 R.Br., [The only locality from which this species has been re- 

 corded is "Valleys of the Blue Mountains, Backhouse."(Fl. Austr., 

 i., 306). In his key to the species (p. 304), Bentham gives, as a 

 distinctive character of .^. involucrata, "Upper leaves simple"; 

 in his specific description he gives "Lower leaves simple." Either 

 of these statements may be accepted, as, in a large number of 

 plants examined in situ, it was found that the position of the 

 simple and trifoliate leaves was about equally distributed (upper 

 and lower), and the foliage would, perhaps, be better described 

 as heterophyllous. The only example of this species in the 

 National Herbarium was collected on the north of the railway 

 near Springwood, by Mr. J. J. Fletcher (x., 1888). The writer, 

 a few years ago, found a group of these plants in a valley on the 

 southern side of the railway-line, between Springwood and the 

 Valley Heights, which may be conveniently entered by a branch- 

 gully commencing at Valley Heights rail way- station. The plants
