opposite, petiolate, lanceolate, glabrous, obtuse. First pr. linear- 

 lanceolate; second 1 x 0*4, petiole 0*6; third 1-8 x 0*6, petiole 06 

 cm First internode 0*6, second 1-2, third IScm. The cotyle- 

 dons are worthy of note, as they differ so greatly from those of 

 the rest of the Mallees, especially those of the E. gracilis type. 



E. populi/olia Hook. (PI. xlvii., fig. 2). — Cotyledons very small, 

 obtusely quadrilateral or orbicular, entire, glabrous, petiolate, 

 0'15x01, petiole 0-15 cm. Leaves opposite, entire, petiolate, 

 glabrous, lanceolate, subacute. First pr. 0*9 x 0*3, petiole 0*4; 

 second 1*2 x 0*5, petiole 0*5; third 16 x 06, petiole 03 cm. First 

 internode 0-4, second 0*3, third 04 cm 



E. quadrangnlata Deane k Maiden (PI. xliv., fig. 7). — Cotyle- 

 dons orbicular- reniform, reddish on under surface, 0*25 x 0*2, 

 petiole 0-15 cm. Leaves narrow-lanceolate, glabrous, opposite, 

 subacute, sessile, reddish on under surface. 



E. iiicrassata Labill. (PL Ixvi., fig.3). — Cotyledons reniform, 

 entire, glabrous, purplish-red beneath, 0-6x0*5, petiole 0*5 cm. 

 Leaves opposite, decussate, entire, glabrous, obtuse, petiolate. 



E. Moorei Maiden &l Cambage (PI. Ixvi., fig. 2). — Cotyledons 

 small, orbicular-reniform, glabrous, purplish on under surface, 

 0-2.X 0*15, petiole 0*15 cm. Leaves opposite, decussate, sessile, 

 lanceolate, obtuse, glabrous, entire, dark green. First pr. 1 x 05, 

 second 2*5 x 0*7, third 3 x 0*8 cm. First internode 0*2, second 

 0*4, third 1, fourth 1*8 cm. Stem purplish-red, covered with 

 short, stellate hairs, terete. This species has been said to be 

 closely related to E. stellidata, but the seedlings are very different, 

 both as to cotyledons and primary leaves; these latter, in E. 

 stellidata, being ovate or almost orbicular. 



ii. Eucalypts with emarginate cotyledons. 



(«). Cotyledons large, slightly emarginate, cuneate at base, 

 petioles long. 



E. marginata Sm. — Described in Lubbock's "On Seedlings." 

 Mr. Maiden's figure, Plate xl., "Critical Revision of Eucalyptus," 

 and description are really of E. calophylla. This error was 

 corrected later. The cotyledons are much more asymmetrical 

 than shown by Lubbock (PI. Ixix., fig. 6).
