19, E. mundijongensis Maiden. 

 In describing the above species in Journ. Roy. Soc. N.S.W., xlvii (1913), I made 

 the following observation at p. 225 : — 



When a tree is isolated, or very rare, there is a temptation to look upon it as a hybrid, and I have 

 considered that view in the present case. It may be a correct one. but I do not know enough about its 

 parents to emphasise the point. I believe it should have a name, and although I have a fair knowledge 

 of Western Australian Eucalypts, it seems quite distinct from any, imperfect as my material is. Locally 

 it is looked upon as allied to the Tuart, E. gomphocepJuda DC. 



20. E. neglecta Maiden. 

 See Part XXVII, p. 151. I am of opinion that this may be a hybrid in which 

 E. ovata Labill. takes a part. 



21. E. Penrithensis Maiden. 

 It is assumed that this may be a hybrid between E. cugenioides Sieb. and 

 E. hcemastoma Sm. var. micrantha. See Part XLVII, p. 215. 



22. E. saligna Sm. and E. acaciceformis Deane and Maiden (?). 

 Mr. A. R. Crawford, Moona Plains, Walcha, sends me specimens with the following 

 note : — " No. 5. Supposed hybrid between E. saligna and E. acaciceformis (Black 

 Peppermint). The tree is from 60-70 feet hi height, rough-barked from the ground 

 to within 5 or 6 feet or less of the smallest twig ; in appearance the tree reminds me of 

 the true saligna, although the bark resembles that of the '' Black Peppermint.' ' 



The fruits of this tree are intermediate in size and shape, and the buds inter- 

 mediate in size and shape between those of E. saligna and E. acaciceformis. The 

 suggestion as to the hybrid origin appears reasonable enough. (Maiden in Proc. Linn. 

 Soc. N.S.W., xxx, 498, 1905). 



On further consideration, I am less confident about this supposed hybrid. 



23. E. Stuartiana F.v.M. and E. nova-anglica Deane and Maiden (?). 

 Seven miles east of Walcha (J.H.M.) we have a tree with Peppermint bark all 

 up the trunk (bark of E. nova-anglica). Suckers narrower than those of E. Stuartiana. 

 Fruits smaller than, but near to those of E. Stuartiana. Foliage intermediate in 

 character between that of Stuartiana and nova-anglica. I am inclined to think this is 

 a case of hybridism. (Maiden in Proc. Linn. Soc. N.S.W., xxx, 499, 1905). 



I have mislaid these specimens, and therefore cannot follow up this case of 

 supposed hybridism. 



24. E. TiENiOLA R. T. Baker. 

 L. Rodway in Proc. Roy. Soc. Tas., 12 (1917), says it seems probable that it is 

 a hybrid between the Black Peppermint (E. amygclalina) and Mountain Ash 

 (E. Sieberiana). 



25. E. vitellina Naudin. 



26. E. vitrea R. T. Baker. 



I am of opinion that these are hybrids between E. amygclalina Labill. and 



E. coriacea A. Cunn. The matter has been discussed at some length in Part VI, 



pp. 164-166, 167 of the present work. See also observations by me in Journ. Roy. 



Soc. N.S.W. Hi, pp. 516-518 (1918).
