NOTKS AND EXHIBITS, 



Mr. Fred Turner gave some particulars, from American 

 records, (Mohr's "Plant-life of Alabama"; and Vasey's "Mono- 

 graph of the Grasses of the United States and British America") 

 of the occurrence and distribution oi Paniaim glahium Gaud,, 

 in the United States— an introduced plant now acclimatised in 

 Australia. He also communicated, from an unpublished source, 

 the late Mr. F. M. Bailey's views on P. yloboideum Domin. 



Mr. A. A. Hamilton showed an additional series of intro- 

 duced or indigenous plants exhibiting teratological developments; 

 and others illustrating leaf- variation, from the National Herba- 

 rium, Sydney, namely— Antirrhinum majus Linn., Hort., show- 

 ing fasciation, spiral torsion, and frondescence. An example in 

 the early stage (W. M. Carne; Sydney Botanic Gardens; Novem 

 ber, 1914) shows the fused stems only slightly contorted, the 

 upper portion branching laterally. Some of the Howers are 

 organically perfect, but exhibit the customary attenuation due 

 to malnutrition, and a considerable reduction in size in the floral 

 leaves. The fruit-capsules are, in the first place, normal in size, 

 and fertile, but become attenuated as the trouble advances, and 

 finally abortive. In an example at a more advanced stage (Hev. 

 J. W. Dwyer; Temora; November, 1914) the contortion of the 

 fused stems has become more pronounced, the leaves and shoots 

 on the upper portion are twisted, and finally reversed; and the 

 flowers are represented by tufts of leaves. — Rosa, Hort. var., 

 "The Bride" (E. Cheel; Penshurst; May, 1911), showing phyllody 

 of the floral organs, accompanied by axial spiral torsion. The 

 axis of the flower is prolonged beyond the abortive ovary, and 

 spirally contorted; the filaments of the stamens are leafy and 

 dilated, the anthers becoming petaloid; and the petals exhibit 

 phyllody, and are much attenuated. Owing to its contortion, 

 the stamens and petals are interlaced spirally on the elongated 

 axis. — Caswarina glauca Sieb., (A. A. Hamilton; Duck River 

 Clyde; May, 1915), showing arrested growth caused by larval
