NOTES AND EXHIBITS. 471 



Betche, Leura(A. A. Hamilton; April, 1914), showing a rosette 

 of basal leaves on one of its branches. The plant, which is a 

 swamp-dweller, had been overturned, and was lying on its side. 

 While in this position, it had produced a basal rosette on the 

 prostrate branch, and rooted it, thus strengthening its resistance 

 to further displacement in its unstable environment. — Acacia 

 suaveolens Willd., Cook's lliver(A. A.Hamilton; August, 1914), 

 an example showing a reversion to juvenile foliage. The plant 

 was found growing in a favourable situation, appeared to be 

 normally healthy, and exhibited no sign of ill-usage, which would 

 be likely to interfere with its ordinary growth. Examples of 

 this species from Leura (A. A. Hamilton; April, 1914), were 

 exhibited, showing the sclerophyllous phyllodes of this xerophyte. 

 It was noted that, on the higher elevations of the Blue Mountains, 

 A . suaveolens is to be found only on the tops of bleak, stony, soil- 

 denuded ridges. A series of leaves was also shown to illustrate 

 variation (A. A. Hamilton; Blaxland; June, 1914) chiefly in the 

 relative proportions of length to width; some measurements are, 

 4i X I; 3 X I; IJ x |; 6 x f^; 4| x -J; 11 x ^V inch.— A^mi/aa^ glycy- 

 phylla Sm., Waterfall^ A. A. Hamilton; June, 1914), a series of 

 leaves showing morphological divergences in size, texture, and 

 shape. The apices of the leaves vary from obtuse to acute and 

 acuminate, and their bases from cordate, rotundate, or elliptical 

 to lanceolate. Measurements, 4| x 1; 2| x If; 3 x |; 2 x :^; 1 x J 

 inch. 



Mr. E. Cheel exhibited a fine series of specimens, representing 

 the following species of Dillwynia : D. parvifolia R.Br., (D. 

 ericifolia var. parvifolia Benth.); between Flemington and Lid- 

 combe (late Rookwood, August, 1898. Fresh specimens again 

 collected in September, 1914). — D. peduncularis Sieb., {D. erici- 

 folia var. peduncularis Benth.), common in the neighbourhood of 

 Randwick; Kahibah, near Newcastle; and Hill Top to Mount 

 Jellore, on the Southern Railway line. — D. phylicoides A. Cunn , 

 [D. ericifolia var phylicoides Benth.), Mount Victoria, Lawson, 

 and several other localities in the Blue Mountains, — The above 

 species are united with D. ericifolia Sm., as varieties by Bentham,
