494 EVOLUTION OP THE EUCALYPTS, 



E. tceniola Baker k Smith (PL Ixviii., fig.2). — Cotyledons ob- 

 tusely quadrilateral, slightly emarginate, 0*45 x 0-4, petiole 0'3 

 cm. Leaves opposite, entire, lanceolate, obtuse, then narrowly 

 lanceolate and acute, subsessile, then sessile, lateral veins oblique 

 and looped with the intramarginal vein, which is away from the 

 edge. Stem and under surface of leaves and cotyledons purplish- 

 red. This seedling is very like that of E . amyydaliiia, but quite 

 different from that of E. viryata, with its broad, primary leaves. 



Fj. coriacea A. Cunn, (PI. Ixiii., fig.l).^ Cotyledons smaller 

 than in most of its congeners, obtusely quadrilateral, not stained 

 on under sides, emargination almost absent, 04 x 0-3, petiole 0*3 

 cm. Leaves opposite, entire, glabrous, ovate or oval, obtuse, 

 shortly petiolate, lateral veins oblique, looped. First pr. 1*2 x 0*7, 

 petiole 0-3; second 2-5 x 1-4, petiole 0-3; third 28 x 1*5, petiole 0-2 

 cm. First internode 0-9, second 1-5, third 1-6 cm. Leaves paler 

 than usual in this class, stem glabrous, green. I would again 

 draw attention to the distinct differences in the seedlings of this 

 and E . phlehophylla. 



E. dives Schau. (PI. Ixiii. , fig.4).— Cotyledons small but obtusely 

 quadrilateral, not coloured on under sides, emargination very 

 slight, lamina 0*3 x 025, petiole 0-25 cm. Leaves opposite, entire, 

 ovate, obtuse, sessile, glabrous, venation well marked, lateral 

 veins oblique and looped, intramarginal veins away from edge. 

 First pr. LI x 0*5, subsessile; second 2 x 09; third 2-5 x L2 cm. 

 Stem terete, glabrous, reddish. First internode 0*7, second LI, 

 third 2, fourth 2 cm. 



E. radiata Sieb.(Pl. Ixiv., fig.4). — Cotyledons obtusely oblong, 

 slightly emarginate, 0*4 x 0-2, petiole 0*2 cm. Leaves opposite, 

 lanceolate then ovate, subsessile then sessile, obtuse, glabrous, 

 venation oblique, intramarginal vein looped and away from edge. 

 Under surfaces of leaves and cotyledons not stained. First pr. 

 1x0-3, petiole 0-2; second L6 x 0*5, third L8 x 0*7 cm. Stem 

 terete, glabrous, greenish. From what I have seen of the seed- 

 lings, I quite agree with those who separate E . radiata from E. 

 amygdaliiia. In the former, we have more oblong, narrower 

 cotyledons, and the first leaves are more ovate and shorter, also 

 subsessile for the first few pairs.
