FIG. 340. 



Eucalyptus leucoxylon, 

 x2. 



Stem square, glabrous, pale green or reddish, ultimately woody ; 

 1st internode 4-5 mm. long ; 2nd 5'5 mm. ; 3rd 4-5 mm. 



Leaves as in E. Globulus but oblong-lanceolate and petiolate ; 

 petioles tapering towards the base, channelled or grooved above. 



First pair narrowly oblong, obtuse, small, 

 tapered to the base. 



Second and fourth pairs oblong-lanceolate, 

 obtuse, tapering at both ends, but mostly at 

 the base. 



Eucalyptus stellulata, Sieb. (fig. 841). 



Fruit a many-seeded capsule, dehiscing 

 loculicidally at the apex. 



Seed small, from '75-1 mm. long, 

 variously angled and shaped, exalbuminous ; 

 testa brownish, smooth ; hilum inconspicuous. 



Embryo straight, filling the interior of 

 the seed, colourless ; cotyledons transversely 

 oblong, convolute and folded round the radicle ; 

 radicle long, stout, truncate at the apex, 

 occupying the centre of the seed and enveloped 

 by the cotyledons. 



Eucalyptus coccifera, Hook. f. 



Hypocotyl terete, woody, glabrous, dark 

 purple near the base, 1-5-2 cm. long, '5-1 mm. 

 thick. 



Cotyledons shortly stalked, -5-'75 cm. long, 

 5 cm. wide, obcordate, cuneate at base, retuse 

 at apex, obscurely nerved, glabrous, not very 

 thick, dark green above, dark purple beneath, 

 rather persistent. 



Stem firm, terete, scabrous, dark purple ; internodes varying 

 from 1-3 cm. in length, 1 mm. thick. 



Leaves as in E. Globulus, but ovate, deep green above, purplish 

 beneath at least in the seedling stage. 



Nos. 1 and 2. Including the short scabrous petiole, 1-1 '5 cm. 

 long, -5 cm. wide, ovate-lanceolate, entire, with sunk midrib and 

 obscurely penninerved, glabrous, thin, dark green above, dark 

 purple beneath in the early stages. 



Nos. 3 and 4. The same, but more oblong, rounded at both ends. 

 Nos. 5 and 6. The same, but larger.
