XX. ABSTRACT OF PROCEEDINGS. 



ous reptile from Lightning Ridge. The specimen is the 

 anterior portion of the right maxillary, with four teeth, of 

 a marine reptile related to the European form Simolestes, 

 one of the Pliosaurs, and is converted into precious opal. 



2. Mr. J. H. Maiden exhibited the following:— 



(i.) Two photographs showing a single branch of Eucalyptus? 

 macrocarpa Turcz., from the York district, W. A. (0. E. Chapman). 

 It bears no less than fourteen flowers, symmetrically arranged in 

 two pairs of rows of three and four each. So large a number on 

 one short branch (18 inches) has not been previously seen by the 

 exhibitor. 



Australian-produced Eucalyptus hybrids. 



(ii.) Coloured drawings of the first hybrid Eucalypts that have 

 been raised in Australia by the direct action of the plant breeder. 

 The Algerian hybrids hitherto described are the results of accidents, 

 plants having been selected in the plantation that could only have 

 arisen as the result of the proximity of certain pairs of species. 

 Mairy of the reputed natural hybrids referred to in Australian 

 literature may or may not be true ; to say that they are so seems 

 justified by the facts in regard to a number of them. These 

 artificial hybrids are the work of Mr. 0. J. Weston, Afforestation 

 Officer, Federal Territory, Canberra. They are 



(a) E. macrorrhyncha x Maideui. 



(b) E. rnbida x melliodora, the former being the pollen 



parent in each case. 



They were pollinated on 8th February, 1918, and Oth December, 

 1917, respectively. Mr. Maiden's specimen of (a) died in May 

 last, when the seedling was two inches high. Of (6) he has two 

 plants, 11 J and 12 inches high on 1st November 1919. They will 

 be described in detail on a future occasion. 



Mr. Maiden also read the following note on — 



Grafts in Eucalyptus. 

 (i.) The cohesion of branches in trees is not common, and in 

 Australia appears to be rare in Eucalyptus. I will take an 

 opportunity later of publishing the evidence I have collected.
