500 EVOLUTION OF THE EUCALYPTS, 



E. saligna var. paUidivalvis R. T. Baker(PL Iv., fig. 8). — 

 Cotyledons obreniform, emarginate, 0-5 x 0-25, petiole 0-3 cm. 

 Leaves opposite, entire, lanceolate, obtuse, glabrous. First pr. 

 0-8 X 0-3, petiole 0-2 ; second 0-9 x 0-35, petiole 0-25 ; third 1-2 

 X 0-5, petiole 0-25 cm. First internode 0-6, second 0-6, third 

 0*3cm. Stem terete, glabrous. 



This seedling is quite distinct from that of E. saligna, the 

 leaves being broader and shorter, and the internodes shorter. 

 The cotyledons are alike, and this would account for the 

 fruits being so much of the same form. 



E. leucoxylon F.v.M.(Pl. Ixvii., fig. 5). — This seedling has 

 been described by Lubbock, but seedlings grown from E. 

 leucoxylon, Dimboola, Victoria, sent me by Mr. Baker, do not 

 tally with Lubbock's description. In these, the cotyledons 

 are transversely oblong, obtuse, petiolate, margin truncate or 

 slightly emarginate, lamina 0-5 x 0-35, petiole 0-3 cm. Leaves 

 entire, opposite, glabrous, slightly glaucous, ovate-lanceolate 

 then ovate, cordate at base, obtuse, first two pairs subsessile, 

 then sessile. First pr. 0-7 x 0-4, second 1-5 x 0-9, third 1-9 x 

 1-1 cm. First internode 1, second 1-3, third 2-5, fourth 3-5 

 cm. Stem terete, glabrous. 



E. patentlnervis R. T. Baker(Pl. Ixiv., fig. 6). — Cotyledons 

 transversely oblong, obtuse, slightly emarginate, sometimes 

 asymmetrical, 0-5 x 0-25, petiole 0-3 cm. Leaves entire, oppo- 

 site, soon alternate, glabrous, lanceolate, subacute, petiolate. 

 First pr. 1 x 0-3, petiole 0-3 ; second 1-3 x 0-45, petiole 0-3 cm. 

 First internode 1-2, second 1-5, third 11 cm. Stem terete, 

 glabrous. 



E. sp. nov., R. T. Baker(Pl. 1., fig. 4). — Cotyledons resemble 

 those of E. leucoxylon, but are purple underneath. Leaves 

 opposite, soon alternate, lanceolate, obtuse, petiolate, edges 

 serrate, veins oblique and parallel. First pr. 1-2 x 0-5, petiole 

 0-6; second 2-3 x 0-8, petiole 0-6; third 2-8 x M, petiole 0-5 

 cm. First internode 1-2, second 1-3 cm. Stem slightly scab-
