examples, a second is added of equal size, the fleshy receptacle 

 becoming sufficiently dilated to allow both to be seated side by 

 side. With the exception of the extra seed, no unusual con- 

 dition is present. — Cassinia aculeata R.Br., (Wentworth Falls; 

 A. A. Hamilton; January, 1915) showing leaf-variation as a 

 result of seasonal growth. The Blue Mountains experienced, in 

 the Spring and Summer of 1914-1915, one of the best seasons 

 for many years= This seasonal change is well marked in the 

 specimens exhibited, which were all taken from a single bush 

 about 6 feet high. The leaves of examples from the old wood 

 range from 2-7 lines long; those of the Spring-growth from h to 

 above 1 inch; while occasional leaves on the Summer-growth 

 reach a length of nearly 2 inches. The crowded leaves of the 

 older, as opposed to the more distant, open foliage of the later 

 growth, is also representative of the differential seasons. — Acacia 

 discolor y^iWd., (Cook's River; A. A. Hamilton; December, 1914). 

 In his key to the Bipinnatse division of Acacias, Bentham (Fl. 

 Austr., ii., 318) places A. discolor Willd., under a group with 

 2-4 pairs of pinnae (rarely 5-6 pairs), the opposing group being 

 credited with 8-15 pairs. In the specific description (loc. cit., 

 p. 414) the leaflets are given as 3-4 lines long. The pinnse, in the 

 specimens exhibited, range from 1 to 8 pairs (one shrub being 

 noted with the whole of its leaves having 7 pairs), and the leaflets 

 from 3 to 7 lines long. — Eustrephiis ^roz^;mi F. v. M., (Cook's 

 River; A. A. Hamilton; July, 1914). The leaf- variation noted 

 in this species is inconsequential, the leaves diftering chiefly in 

 the formation of the apex, and a divergence in length, compared 

 with breadth. 



Mr. Fred Turner exhibited a beautifully variegated leaf -speci- 

 men of Sechium edule Swartz, from the garden of Mr. A. Gale, 

 Stanmore. Although the exhibitor had grown this plant for 

 many years and observed it under cultivation in many parts of 

 New South Wales and Queensland, he had never previously seen 

 it in that condition. If this aberrant growth can be propagated 

 and the plant retain its remarkable variegation, it will V)e a 

 decided acquisition as an ornamental climber.
