484 EVOLUTION OF THE EUCALYPTS, 



The later leaves, tenth to fifteenth pairs, are broad, coriaceous, 

 sessile, often cordate at base, acute, alternate. 



E. dextropinea R. T. Baker (PI. xL, fig.4). — Hypocotyl terete, 

 glabrous, reddish, 0'6 cm. Cotyledons smaller than in E. Icevo- 

 pinea, reddish-purple on under side, sometimes slightly emarginate, 

 0-8 X 0'7, petiole 0-4 cm. Leaves broader than in E. Irevopinea, 

 purplish-red on under surface, dark green, subsessile, opposite, 

 obtuse, margin waved or serrated, ovate-lanceolate, veins pinnate 

 and looped. First pr. 2*1 x 1; second 3*6 x 1*5; third 4 x 1-8 cm. 

 First internode 0-4, second 0-5, third 0-6 cm. Stem terete, 

 greenish, and it and leaves covered with stellate hairs. 



E. Wilkinsoniana R, T. Baker (PI. xli., fig. 2). —Hypocotyl 

 erect, terete, glabrous, 1 cm. Cotyledons smaller than in E. 

 loivopinea, reniform, entire, glabrous, 0-4 x 0-3, petiole 0*3 cm. 

 Leaves ovate or oval, petiolate, margin serrate or sinuate, obtuse, 

 opposite, venation pinnate. First pr. 1-5 xO" 6, petiole 0*4; 

 second 3 x 1*2, petiole 0-5; third 3-3 x To, petiole 0*4 cm. Stem 

 and leaves covered with glandular hairs. First internode 0*9, 

 second 1-8, third 1-6 cm. Leaves, especially from fourth to 

 seventh pairs, have margins much more sinuate than in E. nigra. 



E. macrorhyncha F.v.M. (PL Iviii., fig. 6). — Hypocotyl as in 

 other members of the group. Cotyledons as in E. Wilkinsoniana, 

 only very dark purple on under surface. Leaves ovate-lanceolate, 

 obtuse, opposite, petiolate, margin sinuate. First pr. 2 x 0'9, 

 petiole 0-6; second 3 x 1*8, petiole 0*5 cm. First internode 1*2, 

 second 2-5, third 1-8 cm. Stem and leaves covered with glandular 

 hairs. 



E.capitellata Sm. (PI. Iviii., fig.7).— Cotyledons as in E. Wil- 

 kinsoniana, only rather cuneate at base, petiole longer. Leaves 

 much like those of E. macrorhyncha, only narrower. 



E. 7iigra R. T. Baker (PI. lix., fig. 1).— Cotyledons and leaves 

 closely resemble those of E. Wilkinsoniana, but leaves not so 

 obtuse and rounded at apex as in that species. 



E. eugenioides Sieb. (PL xliii., fig. 2). — Cotyledons reniform, 

 smaller than in E. Wilkinsoniana, 0"3x0-25, petiole 0-3 cm. 

 Leaves narrower than in the other Stringybarks, lanceolate, 

 opposite, decussate, petiolate, subacute, margin sinuate. First pr.
