13. E. Kitsoniaxa (Luehinann) .Maiden. 

 See Pari XXVIII, p. 164. 

 I am of opinion that this may be a hybrid in which E. ovata Labill. plays a part. 



14. E. Laseroni R. T. Baker, 

 which is assumed by me to be a hybrid between E. eugenioides Sicb., and E. stcllvlata 

 Sieb. See Part XLVII. p. 1S8. 



15. E. leucoxylon F.v.M. and (?) E. fasciculosa F.v.M. 

 Mr. Walter Gill, Conservator of Forests, Adelaide, sent me herbarium specimens, 

 timber and bark, of an aberrant tree from Kuitpo, South Australia, with the following 

 note : — " I send you a specimen of E. leucoxylon timber showing a very red heartwood, 

 which I have only seen in this district, the northern Blue Gum (E. leucoxylon) being all 

 one colour." 



The herbarium specimens are obviously strongly akin to those of E. leucoxylon 

 F.v.M. (They also resemble those of E. sideroxylon A. Cunn., birt I do not know an 

 individual of that species nearer than some hundreds of miles.) The timber is deep 

 red, and the bark is somewhat fibrous (Box-like), characters rarely present in 

 E. leucoxylon. It seems reasonable to look upon this rare plant as a hybrid, and as to 

 the other parent, Mr. Gill suggests E. fasciculosa as likely. The points in which these 

 specimens differ from E. leucoxylon could be supplied by E. fasciculosa, a red-timbered 

 species abundant locally. (Maiden in Proc. Linn. Soc. N.S.W., xxx, p. 497 (1905) ). 



16. E. longicornis F.v.M. x E. fcecunda Schauer. 

 The late Mr. Henry Johnston, Surveyor-General of Western Australia, told me 

 that he had given the descriptive name of " Yorrel " to a supposed hybrid between 

 York Gum (E. fcecunda Schauer) and the Morrel; it seemed to him to have the timber 

 of the York Gum and the twigs of the Morrel. 



I have not been able to obtain twigs of any of Mr. Brockman's or of Mr. Johnston's 

 supposed hybrids, so I cannot express an opinion as to their botanical relationships, 

 but 1 think it highly probable that hybridism does explain the puzzling variations to be 

 referred to in regard to the Morrels. (Maiden in Journ. Roy. Soc. N.S.W.. xlix, p. 325, 

 1915.) 



■ 17. E. longicornis F.v.M. x E. occidentalis Endl. 



The use of the name " Morrel," which is one of the most used names in Western 

 Australia, is referred to in the present work, Part XV, pp. 160-7. It is usually applied 

 to E. oleosa F.v.M. var. longicornis F.v.M. 



Mr. Fred. Bro.danan. then Chief Surveyor of Western Australia, and whose knowledge of the trees 

 of that State was very extensive, in an interesting interview, suggested hybridism in regard to the " Morrel." 

 He ugg 'hat the Yate (E. occidentalis Endl.) from the south coast of Western Australia and the Morrel 

 from the eastern district of Western Australia [E. oleosa F.v.M., var. longicornis F.v.M.) probably have 

 met say in the latitude of Eatanning, and " from the common point of process of hybridising has proceeded 

 spreading northward until Yate ii lo I in Morrel. and southward until Morrel is lost in Yate." (Maiden 

 in Journ. Roy. Soc. N.8.W., xlix, 325, 1015.)

 In Proc. Ln,n. Soc. N.8.W. xxx, 200 (1905), Maiden and Cambage fully describe, 

 under the letter \'>. a form thai they assume to be a hybrid of the above two species.
