He goes on to say : ; ' I have invariably maintained that the first branches of 

 these (adventitious) shoots, as well as their leaves, have always their juvenile form and 

 structure, whatever may be the part of the tree from which they have arisen." Then 

 (p. 288) he quotes M. Naudin, who cites E. viminalis in addition to E. globulus. 



Naudin, Ch. Then we have Naudins remarks (1st Mem., 347, 1883, and 2nd 

 Mem.. 16. 1891), quoted at Part LVI, p. 283 (last paragraph but one from bottom), 

 in which he speaks of the variations of shapes of leaves in the seedling stage, especially 

 noting the "'first six or eight leaves" (Naudin II. 16). See also p. 284, paragraph 

 after that headed " First Foliage." 



The following passage from Naudin, I, 347 (translation) is the first definite 

 account we get of the (sometimes) puzzling characters of the leaves of the seedlings 

 which follow those of the cotyledons :— 



" The variations are very much greater in the stage which follows (the cotyledons), and it is there, 

 indeed, that the difficulties of specific diagnosis commence. The first leaves which follow the cotyledons 

 have seldom the shape of those which appear in a more advanced stage. They are sometimes alternate 

 and petiolate from the commencement, more often they are opposite and sessile or almost sessile, but while 

 in many of the species this last characteristic affects the six or eight first leaves, in other species also a great 

 number, they remain sessile and opposite during a long period of the youth of the tree, and sometimes foi 

 its whole life." 



Lubbock, J., I, 526 (1892) (with figures). " They all agree in having the primary 

 leaves (I have used the term ' juvenile,' J.H.M.) opposite and entire, but these differ 

 slightly in form. Those of E . globulus are linear-lanceolate; of E. rostrata, E. cordata 

 and E. leucoxylon lanceolate; of E. stellulata oval; of E. coccifera, E. marginata and 

 E. ficijolia ovate; of E. occidentalis oblong; and of E. calophylla cordate, covered 

 on both surfaces with crystalline glands. The primary leaves of many individual 

 specimens of E . ficifolia are more or less distinctly alternate." 



Deane and Maiden (top of p. 287), quoting Proc. Linn. Soc., N.S.W., XX, 597 

 (1895) and other places throughout that series, used the terms Seedling or Sucker leaves 

 as interchangeable. In some of the earlier Parts of the present work I followed the 

 same practice, but as I found it was misleading I abandoned it. 



Under the caption " Juvenile Leaves " we have references, including — " Between 

 these stem- shoots and seedling-leaves there is a great similarity ... we may 

 regard these reversion shoots as of almost equal value with the seedlings for the purpose 

 of studying the ancestral forms of Eucalypts." (E. H. Cambage, in Journ. Roy. Soc., 

 N.S.W., XLVII, 41, 1913, quoted at bottom of p. 288, Part LVI). 



Dr. Outhbert Hall in " Evolution of the Eucalypts," Proc. Linn. Soc, N.S.W., 

 XXXIX, 519, 1914, says : " The so-called sucker-leaves are of the same form as the 

 seedling-leaves. . . ."
