In Decade IV, under E. clavigera, he says : ' The sections Renantherse and 

 Hemiantherse are, as far as hitherto known, not represented in North Australia." I 

 have spent a good deal of time in a vain endeavour to find any further reference to 

 the word " Hemiantherse," but without success. In January, 1908, I appealed to 

 Professor Ewart, and he told me he was unable to trace it. The term " Hemiantherse " 

 seems not to have been taken up by Mueller or anyone else ; it is indeed one of those 

 superfluous terms foisted on a science already overburdened with terms. 



1895. " Eucalyptus," by Abbot Kinney, Los Angeles, U.S.A.' The botany 

 by A. J. McClatchie. 



Mr. McClatchie adopts Mueller's four groups of the " Eucalyptographia," but 

 makes certain alterations as to species in the Renantherse (p. 180) and other groups. 

 He offers greatly enlarged drawings of anthers, viz. : — 



Renantherse (E. amygdalina). 



Porantherse (he chooses E. polyanthemos, a species I have put in the Terminales). 



Strongylantherse (E. diversicolor, which has a large gland, the cells a little 

 divergent, and opening in slits ; E. siderophloia, gland small, and cells opening 

 in pores). 



Orthantherse (E. rostrata and E Gunnii, both opening in slits, but the former with 

 cells narrower than the latter). 



1898. Luehmann (Proc. Aust. Ass. Adv. Sci. vii, 523, 1898) expresses the opinion 

 that the anther system is the most reliable which, with our present knowledge, can 

 be devised. 



Andrews, 1913. E. C. Andrews in his paper, " The Development of the 

 Natural Order Myrtacese," Proc. Linn. Soc. N.S.W .,xxxviii (1913), makes an extensive 

 use of the anther in Eucalyptus. The whole paper should be carefully read. Following 

 is a mere paragraph : — 



" The typical anthers of the family are versatile, the cells parallel and opening longitudinally. 

 Thus the Angophoras and Corymbosas have the typical anthers of Myrtacese, but the Boxes and Ironbarks 

 possess peculiar porose or truncate anthers, and the Stringybarks, Peppermints, Messmates, Mountain- 

 Ashes and some Mountain Gums possess kidney-shaped anthers " (p. 566). 



Cambage, 1913. Following is from Mr. R. H. Cambage's Presidential Address 

 read before the Royal Society of New South Wales. He deals with climate and soil 

 in relation to the anthers : — 



" . . . . In a large genus like Eucalyptus it is not surprising to find that there is a gradation of 

 characters from one species to another, and this varietal tendency applies in a marked degree to the 

 anthers. But on studying the distribution of the three general types of anther, it becomes evident that 

 to some extent such distribution is regulated by climatic influence, .or that a certain form of anther is 

 often better represented in one class of climate than another.
