486 EVOLUTION OF THE EUCALYPTS, 



venation pinnate, ratlier oblique, edges sinuate. First pr. 0*8 x 0"3, 

 petiole 0*25; second 1*5 x 0-6, petiole 0-3; third 3-6 x 0-8, petiole 

 0-3 cm. First internode 0-3, second 0*4, third 0*9, fourth 2 cm. 

 Stem reddish, and both it and leaves covered with fine stellate 

 hairs. This seedling has some resemblance to those of E. Moorei 

 (Maiden), and E. euyenioides. 



E. regnans F.v.M. (PL Ixvi., fig. 1). — Cotyledons reniform, 

 entire, 0'6 x 0-45, petiole 0-3 cm. Leaves opposite, ovate-lanceo- 

 late, with sinuate and slightly serrate margins, petiolate, vena- 

 tion somewhat oblique, intramarginal vein close to edge, upper 

 surface smooth and shining; lower surface with a few stellate 

 hairs; oil-dots few in number. First pr. 2-5 x 1, petiole 0*3; 

 second 3*3 x 1*5, petiole 0-3 cm. First internode 0-5, second 08 

 cm. Stem and leaves covered with short, glandular hairs. 

 Although this species has a smooth bark, the seedling is so much 

 of the type of the Stringybarks, that I have placed it with them. 

 The reniform anthers, it possesses, also support this grouping. 



E. fastigata Deane & Maiden (PI. Iviii., fig. 5). — Cotyledons 

 small, reniform or triangular, petiolate. Leaves opposite, but 

 soon alternate, entire, shortly petiolate, then petioles longer, 

 lanceolate, acute, oil-dots fairly numerous. Venation oblique; 

 intramarginal vein away from edge and looped with lateral 

 veins. Leaves and stem covered with fine hairs, but soon becom- 

 ing smooth. This seedling is quite distinct from that of E. 

 regnans^ having smaller cotyledons, much narrower lanceolate 

 leaves of fine texture, and fairly plentiful oil-glands, so agreeing 

 with the results of the distillation of the oils. 



i.(c). Cotyledons small, entire, reniform or orbicular. Leaves 

 mostly glabrous and petiolate. 



E. Dmvsoni R. T. Baker (PI. Iviii., fig.4). — Cotyledons reniform, 

 glabrous, 0*4 x 0*3, petiole 0-3 cm. Leaves entire, opposite, de- 

 cussate, glabrous, petiolate, lanceolate, acute. I was able to 

 raise only one seedling of this species, but, by comparison, a great 

 difi'erence will be seen between it and those of E. ovalifolia and 

 E. polyanthema. 



E. dumosa A. Cunn.(Pl. liii., fig. 2; PL Ixix., fig. 5). — Cotyledons 

 reniform-orbicular, glabrous, 0*25 x 0*2, petiole 0-3 cm. Leaves
