base, opposite, decussate, obtuse, petiolate then sessile, glabrous, 

 purplish OQ under sides. First pr. 2*5 x 0*7, petiole 0*5; second 

 5x2, subsessile; third 5x2 cm., sessile. Lateral veins parallel, 

 oblique. First internode 0*6, second 1, third 3cm. Stem terete, 

 glabrous. 



E . stricta Sieb. (PI. liv., fig. 5). -Cotyledons almost orbicular, 

 emargination slight or none, 0*5 x 0*4, petiole 0-4cm., deep purple 

 beneath. Leaves opposite, lanceolate, obtuse, entire, glabrous, 

 shortly petiolate then subsessile, purplish beneath, venation 

 oblique, pinnate. First pr. 2*2 x 0-9, petiole 0*3; second 3-3 x I'l, 

 petiole 2 cm. First internode 0*6, second 1, third 0-8 cm. 



E. Eossii R. T. Baker and H. G. Smith (PI. xlviii., fig.6).— 

 Cotyledons closely resembling those of E. stricta, and are slightly 

 emarginate, and broader than in that species. Leaves lanceolate 

 and petiolate, then oval or ovate and subsessile, obtuse, opposite, 

 entire, glabrous, venation somewhat oblique, tinged red on under 

 sides. First pr. l-5xO-6, petiole 0*3; second 2 4x1*2 cm., sub- 

 sessile. First internode 0*6, second 1*1, third 1*1 cm. 



Messrs. Baker and Smith class E . Rossii with the eucalyptol- 

 pinene group, and E . stricta with the euealyptol-pinene-aroma- 

 dendral group, the members of which, as a rule, have parallel 

 anthers, while these have reniform anthers. The seedlings ex- 

 plain the seeming anomaly, as these species are now shown to 

 have great affinity to the " Peppermint " group, and, apart from 

 their chemical composition, should be placed therein. 



E . striaticalyx (PI. Iv., fig.3). — Hypocotyl terete, glabrous, 

 reddish, l*5cm. long. Cotyledons obtusely quadrilateral, glabrous, 

 purplish on under sides, 0*6 x 0*5, petiole 0*5 cm. Leaves entire, 

 glabrous, opposite, obtuse, petiolate, ovate-lanceolate or ovate. 

 First pr. 1*2 x 0*5, petiole 0-6; second 2x1, petiole 06 cm. First 

 internode 0*6, second 0*9, third 1*7 cm. Stem terete, glabrous. 

 Though the cotyledons are of the same form, the leaves are 

 different from those of the others of the group. 



E. piperita Sm. (PI. Ix., fig.3; PI. Ixix., fig. 9).-- Cotyledons ob- 

 tusely oblong, slightly emarginate, purplish on under sides, 0*6 x 

 0*5, petiole 0*2 cm. Leaves opposite, ovate-lanceolate, obtuse, 

 petiolate then sessile, glabrous, entire. First pr. 1*3 x 06, petiole
