Exhibits. — Prof. Tate, F.G.S., exhibited a grass (Aristida 

 depressa) from Mount Lyndhurst (collected by Mr. Koch) new to 

 South Australia. Also a sedge {Cyperus Icevigatns) from River 

 Hindmarsh (collected by Miss J. L. Hussey), first found in South 

 Australia at Nilpena, but in an extreme varietal form, and this 

 year J. H. Maiden, Government Botanist of N.S.W., has received 

 a specimen of it from Mount Lyndhurst. The Port Elliot plant, 

 which in its Schcenus-like habit represents the typical form 

 widely spread over warmer regions of the world, chiefly in 

 maritime districts, has hitherto only been known for Australia at 

 Swan River, W.A.
