seen it in that condition (vide Agricultural Gazette of New South 

 Wales, Vol.iv., p. 31 2, for a record of another abnormality). He 

 also referred to the fungus Lysurus australiensis C. & M., which 

 had lately sprung up pretty plentifully on a buffalo grass lawn 

 at North Sydney. 



Dr. Cleland contributed a " Note on Twists in the Bark of the 

 Jarrah (Eucalyptus marginala Sm.)." Of one hundred trees 

 observed in the neighbourhood of Perth, W.A., four showed a 

 decided left twist, sixteen a slight left twist, forty-four were 

 straight, twenty-four showed a slight right twist, nine a marked 

 right twist, and in three the twist was undecided (i.e., irregular). 

 As there appeared to be no indication of a tendency to tree-growth 

 in a spiral direction, the explanation was offered that, when 

 young, a predominant branch probably extended to one or other 

 side and, being played on by the prevailing wind, caused the 

 young stem to become twisted to some extent. Later such a 

 branch may have died and disappeared. The explanation offered 

 seems to be favoured by the fact that contiguous trees are often 

 twisted in opposite directions. 



Mr. Fletcher showed specimens of Loranthus Bidwillii Benth., 

 from north of the Warrumbungle Mountains, collected by Dr. H. 

 I. Jensen, the host being a species of Pine (Callitris sp.); and 

 from near Young, N.S.W., parasitic upon the Black Pine (Callitris 

 calcarata R.Br.), collected by Mr.T. G. Sloane. The species was 

 described in the "Flora Australiensis" from Wide Bay, Q., 

 without reference to the host; it was subsequently found in South 

 Queensland upon Callitris cupressiformis Vent., by the late Rev, 

 B. Scortechini [Proc. Linn. Soc. N.S.Wales, viii.p. 251, 1883]; and 

 recorded for the first time from New South Wales upon Callitris 

 sp. by Mr. R. T. Baker from Murrumbo, Goulburn River [op. 

 cit. 1896, p. 452]. Though not common, the species is evidently 

 fairly widely distributed; and it is of interest because, so far as 

 known, it seems to be exclusively associated with Conifers.
