512 EVOLUTION OF THE KUCALYPTS, 



E. cneorifolia DC. (PL liii., fig. 6). — Cotyledons as in E. 

 oleosa. Leaves linear, then obovate-lanceolate, obtuse, sub- 

 petiolate, glabrous, opposite, after fifth pr. alternate. The 

 leaves are quite distinct from those of the closely allied species 

 in this group. 



E. gracilis F.v.M.(Pl. liii., fig. 7). — Cotyledons Y-shaped, 

 limbs linear, 0-2, petiole 04 cm. long. Leaves linear and 

 acute, then lanceolate and obtuse, opposite, entire, glabrous, 

 tapering into a short petiole. First pr. 1-2, second 1-6, third 

 1-8, fourth 2-4 cm. First internode 0-6, second 0-5, third 0-8, 

 fourth 0-5 cm. Stem terete, glabrous. 



E. pendula A. Cunn.(Pl. xlix., fig.2 ; PI. Ixix., fig. 23).— 

 Cotyledons Y-shaped, the limbs linear and 0-18 cm. long, 

 petiole 0-3 cm. Leaves opposite but soon alternate, glabrous, 

 entire, acute then subacute, linear then lanceolate, shortly 

 petiolate. Internodes longer than in E . gracilis. 



E. calycogona Turcz.(Pl. Ixvi., fig.5 ; PI. Ixix., fig. 22). — 

 Cotyledons Y-shaped, limbs narrowly obovate, asymmetrical, 

 0-25 cm. long, petiole 0-5 cm. long. Leaves opposite, then 

 after few pairs alternate or even becoming alternate in first 

 pair, entire, glabrous, linear and acute, then lanceolate and 

 subacute, distinctly petiolate. First pr. 11 x 015, petiole 0-3; 

 second 1-3 x 0-25, petiole 0-3; third 1-5 x 0-3, petiole 0-3 cm. 

 First internode M, second 1, third 0-9 cm. Stem terete, green- 

 ish, glabrous. 



This species is quite distinct from E. gracilis in the seed- 

 ling, and thus receives confirmation of the evidence for its 

 specific rank. The limbs of the cotyledons are obovate instead 

 of linear as in E. gracilis, while the leaves are more charac- 

 teristically lanceolate and petiolate than in that species. The 

 internodes too are generally longer. 



E. uncinata Turcz.(Pl. Ixvi., fig. 6). — Cotyledons Y-shaped, 

 limbs almost linear but not so narrow as in E. gracilis, 0-25 

 cm. long. Petioles flattened and greenish in their outer half, 

 6 cm. long. Leaves entire, opposite, glabrous, linear or 

 narrowly oblong-linear, obtuse, tapering into a short petiole.
