alternate, petiolate, drying a yellowish-brown, citron-scented. 

 First pr. opposite, 1 x 0-3, petiole 0*2; second 1*2 x 0-5, petiole 04; 

 third l'8xO"7, petiole 0*4 cm. Stem and leaves rough, with 

 short glandular hairs. 



E. macidata Hook. (PI. xliv., fig.l). — Hypocotyl erect, terete, 

 glabrous, 0*9 cm. long. Cotyledons as in E. ciiriodora, but 

 smaller and more orbicular, subsessile, entire, 0*65 cm. in diameter. 

 Leaves ovate, obtuse, alternate, petiolate, then peltate for a few 

 pairs, becoming again petiolate, dark green. Venation oblique, 

 with often two main lateral veins springing from near petiole. 

 (This is seen, too, in E. citriodora). Leaves and stem have 

 glandular hairs. These two species are of special interest. E. 

 cit7'iodora has sometimes been put as a variety of E. macidata, 

 but should not. However, they raise a point I wish to emphasise, 

 that when, in allied species, the fruits closely resemble each 

 other or are practically identical, the cotyledons also resemble 

 one another. This obtains specially in these two species, and 

 their being subsessile, separates them from all other species of 

 Eucalypts, yet they differ in primary leaves, oils, bark, timber, 

 habitat, etc. The colour of E. citriodora, on drying, is also worthy 

 of comment, and is probably due to its chemical composition. The 

 peltate leaves emphasise their relation to the Bloodwoods. The 

 primary leaves of E. macidata have some resemblance to those of 

 E. eximia. 



i.(6). Eucalypts with reniform, entire cotyledons; "stringy" 

 bark ; shortly petiolate primary leaves with glandular hairs. 

 Though the cotyledons are entire and the leaves hairy, the group 

 differs from the Bloodwoods in the primary leaves being opposite 

 and shortly petiolate. 



E. kevopinea R. T. Baker (PI. xL, figs. 1-2). — Hypocotyl terete, 

 glabrous, reddish, 0-7 cm. long. Cotyledons obtusely quadri- 

 lateral, reniform or cuneate at base, entire, glabrous, reddish 

 underneath, 0*9 x 0"8, petiole 0*3 cm. Leaves broadly lanceolate, 

 subacute then acute, opposite, shortly petiolate, margin waved or 

 slightly serrate, venation pinnate. First pr. 2 x 0*9 ; second 

 3-5x1 '5 cm. Stem and leaves with glandular hairs. Stem 

 terete, reddish. First internode 0*7; second 0-8; third 2 cm.
