NOTES AND EXHIBITS. 



Mr. Cheel showed fruits of tomato {Li/cope7-sicum esculentiim)^ 

 infested with the Sleeping Disease {Fusarium lycopersici Sacc), 

 found at Penshurst. Cases of this disease were previously found at 

 Gosford in December, 1899, by Mr. Froggatt, and afterwards by 

 the late Mr. A. Grant among plants growing in the Botanic 

 Gardens, Sydney, in February and April, 1903. In Great 

 Britain, according to Mr. Massee, the disease causes very great 

 damage to tomato-crops. 



Mr. Tillyard exhibited a larva of St/ntheniis eustalaeta Burm., 

 (Neuroptera : Odonata) which had been without food for three 

 months, and had been subjected to gradual drought-condition.s 

 culminating in three weeks of complete absence of water. The 

 insect was still alive and quite healthy. Tliree others, though 

 apparently lifeless when first examined, quickl}' revived when 

 dropped into water. This seemed to be the first absolute proof 

 of the ability of any dragonfly larva to stand a complete drought. 



Mr. T. H. Johnston showed a fine specimen of a tomato affected 

 by the Irish Blight-fungus {Phytophthora infestans). The exhibit 

 was grown in the Sydney district. Though it is well known that 

 tomatoes are susceptible to this potatodisea.se, infected fruits 

 are very seldom met with, though tomato-plants may be growing 

 side by side with potatoes which are badly blighted. 



Mr. Fred Turner exhibited, and offered observations on^ two- 

 species of Chenopodiacece, viz., Auisacantha divaricata R.Br., and 

 Sclerohena bicornis Lindl.,from theBrewarrina district, New South 

 Wales. On one pastoral holding three years ago only a few scattered 

 shrubs of the former were to be found; now they were to be seen 

 covering an area of twenty-five thousand (25,000) acres to the
