510 EVOLUTION OF THE EUCALYPTS, 



lanceolate, subsessile then sessile, cordate at base, obtuse. 

 First pr. 0-7 x 0-2, petiole 0-2 ; second 2 x 0-35, subsessile ; 

 third 3-3 x 1 cm. First internode 0-8, second 10, third 1-2, 

 fourth 2-5 cm. 



?J. globulus .Labill.(Pl. xlviii., fig. 3 ; PL Ixix., fig. B).— This 

 has been described in Lubbock's "On Seedlings." I would 

 point out that the leaves of the first pair are narrower, and 

 proportionately longer than in E . Maideni and E. uiualata. 



E. sp. nov., R. T. Baker(Pl. Ixviii., fig. 4; PI. Ixix., fig. 19). 

 — Cotyledons fairly deeply emarginate, the lobes asymmetri- 

 cal, obovate-oblong and obtuse, cordate at base, purple on 

 undersides, 0-9 x 0-3, petiole 04 cm. Leaves entire, opposite, 

 glabrous, glaucous, ovate, obtuse, sessile, cordate at base, 

 stem-clasping. First pr. 1-8 x 0-7, second 2 x 1-0, third 2-4 x 

 14 cm. First internode 14, second 1, third 11cm. Stem 

 glabrous, terete, purplish at first, then quadrangular as in E . 

 globulus. This species plainly belongs to the global us-c\3iss, 

 and the cotyledons are very similar, but the emargination is 

 not so deep in this species, hence the lobes are more obtuse 

 and almost in a straight line. The leaves are more glaucous 

 and much broader, being ovate and obtuse. 



E. gomphoccphala DC.(P1. liv., fig.3 : PI. Ixix., fig. 20). — 

 Cotyledons deeply bifid, lobes diverging at an angle of 120 

 degrees, obtuse, asymmetrical, lamina 0*7 cm. across, petiole 0*6 

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

 First pr. 1-1 x 0-5, petiole 0-3 ; second 1-8 x 0-8, petiole 0-3 cm. 

 First internode 0-5, second 04, third 04 cm. The cotyledons 

 of this species show transit from others in this group, such as 

 E corynocalyx, to E . coniuta and thence to those with still 

 narrower lobes or limbs, as E . redunca. 



\\.{d) Cotyledons so deeply bifid as to represent the letter 

 Y. Lobes narrow to linear, and as long as, or even longer 

 than the petiole. Leaves generally petiolate and glabrous. 



E. cornuta Labill.(Pl. liv., fig.2 ; PI. Ixix., fig. 21). —Coty- 

 ledons deeply bifid, the lobes unequal and narrower than in
