396 NOTES AND EXHIBITS. 



Mr. H. L. White, of Belltrees, sent, for exhibition, four fossil 

 vertebrae from about the median portion of the dorsal region of 

 Cimoliosaurus australis Owen, found about 50 miles west of 

 Richmond, Queensland, wliere an extensive deposit of fossil 

 remains is said to occur. There are three known types of these 

 Ichthyopterygians in the Lower Cretaceous of Australia, viz., 

 Cimoliosaur'us, Ichthyosaurus, and Plesiosanrus, remains of which 

 have been found in Queensland and New South Wales. 



Mr. E. Cheel exhibited fresh specimens of the common ground- 

 sel {Senecio vuhjaris L.) attacked with Pucciiiia tasmanica Diet , 

 collected at Gordon by Mr. A. H. S. Lucas. For previous 

 records, see the Society's Proceedings, 1910, xxxv., pp.524 and 

 805. 



Mr. G. A. Waterhouse exhibited a long series of the five de- 

 sciibed geographical races of I'isijjhone abeotia Don. 



Mr. A. A. Hamilton showed a series of specimens from the 

 National Herbarium, including {l)JIt/pochaeris {ip.{W est Maitland; 

 W. M. Carne; April, 1914), showing prolification of the inflor- 

 escence. In the initial stages, the ray-florets are suppressed, the 

 achenes attenuated, and the pappus contorted, the capitula being 

 finally reduced to a series of bracts. In the more complicated 

 case, a lateral stem arises from the base of the primary plant, 

 bearing a second plant, which, in its turn, has produced a third, 

 the two latter having the appearance of stolons but not rooting. 

 From the primary capitula of the intermediate plant, peduncles 

 are produced, upon which abortive florets are situated, one above 

 the other at short distances apart, the stems continuing through 

 them, and terminating in secondary capitula in which the process 

 is repeated, the secondary peduncle also perforating one or more 

 florets. — {'2)Primul(i vulgaris Huds., [Sydney Botanic Gardens 

 (cult.); W. Challis; October, 1913] exhibiting prolification of the 

 inflorescence accompanied by fasciation. A few flowers ascend 

 in the usual manner from the short caudex, which has elongated 

 and become fasciated; upon the apex of this secondary stem, an 

 abnormal number of involucral bracts are produced, indicating 

 that several scapes are represented; a second series of flowers arise
