XXVIU. ABSTRACT OP PROCEEDINGS. 



Wing-s white with a light purple-brown streak on the lower margin. Keel dark 

 purple-brown shading to black; (2) A large flowering variety of Lasiopetalum 

 rufum K.Br., from Berowra (W. F. Blakely and D. W. C. Shiress) which differs 

 from the normal form in the larger leaves, and large, showy, flesh-coloured 

 flowers. Mr. Blakely also exhibited a beautiful hand painting of Loranthus 

 alyxifoUus F.v.M., on its host Alphitonia excelsa Reiss., by Mrs. C. F. Tindal, 

 Ramornie. Flowers and buds various shades of old blood red (Plate 103, Dau- 

 thenay. Repertoire de Couleurs). Anthers saffron yellow (Plate 48). The ad- 

 ventitious roots are similar in appearance to the branches of the parasite, and 

 they possess, also, the same general tone as the bark of the host. 



Mr. E. Cheel exhibited a fresh flowering specimen of Callistemon, having 

 flowers of a rich reddish plum colour {see Dauthenay's Repertoire de Couleurs. 

 PL 174 (4) given as "Deep Carmine Violet"). The plant is one taken from a 

 batch of seedlings raised from seeds of a creamy-white flowering form of C. 

 lanceolata var. lilacina Hort., originally raised from seeds received from Berlin 

 in 1913 (see These Proceedings, 1916, 'p. 219 and 1917, p. 512). It is interest- 

 ing to note that specimens have been collected at Gosford in a natural state, and 

 forwarded to the National Herbarium for identiflcation, having identical coloured 

 filaments and anthers, as one of the forms raised from the seeds obtained from 

 Berlin. 



The specimens collected at Como (see TTiese Proceedings, 1903, p. 884) belong 

 to this series rather than to the typical C. rugulosm DC (C. coccineus F.v.M.) 

 which is an interior species. 



Mr. N. B. Friend exhibited a specimen of picramie acid, CgH2(N02)2 

 NH2. OH, prepared by him in the laboratory of the Royal North Shore Hos- 

 pital, by reduction of picric acid. 



Professor T. T. Flynn sent, for exhibition, a photograph that is practically 

 unique in depicting the actual process of parturition in an Australian marsupial, 

 Potorous tridactyhis.^ The organs are shown from the dorsal side and the em- 

 brjro is lying on its left side in the left lateral canal. The photogTaph shows 

 that in this case parturition takes place through the lateral canals and not 

 through a median passage as Fletcher and Stirling have shown in the case of 

 twelve species of Macropus.
