orbicular cotyledons, the largest so far known among Eucalypts, 

 and larger than any in the Angophoras; the petioles are really 

 longer than are shown in Lubbock's diagram, and the leaves 

 alternate from the beginning. The incipient emargination men- 

 tioned by Lubbock is usually due more to separation and splitting 

 during germination. The stellate hairs on the petioles of coty- 

 ledons are unusual. The earlier leaves tend to become peltate 

 for a few pairs, a character they afterwards lose. The leaves 

 are very like those of E. corymbosa. It is noteworthy that this 

 species and E. Jicifolia are the only ones of the Corymbosa- or 

 Blood wood-group found in South-western Australia. (PI. Ixix., 

 fig.4). 



E. corymbosa^m. {Plate xxxviii., fig. 4). — Hypocotyl erect, 

 terete, glabrous, 1-2 cm. long. Cotyledons LI x 0*8 cm., petiole 

 0-7 cm., entire, reniform, glabrous, purplish on under surface, 

 sometimes with a small apical point. Stem erect, terete, herba- 

 ceous, ultimately woody, greenish but drying to red, covered 

 with glandular hairs. Leaves alternate, petiolate, entire, ovate 

 to oval; lateral veins rather oblique, open; petioles and laminae 

 covered with glandular hairs. In the very young stage, the 

 leaves have a purplish tinge. First pair, L3 x 0*5, petiole 0-7; 

 second pr., 2-5 x 0*9, petiole 1; third pr., 3*2 x L2, petiole 1 cm. 

 First internode 2-5, second internode L2cm. Leaves assume a 

 peltate character, which they lose again. Later leaves are cori- 

 aceous, smooth and shining, large and broad, with lateral veins 

 parallel, more closely set and almost at right angles to the mid- 

 rib. (PI. Ixix., figs. 3, A, D). 



E. eximia Schau. (Plate xxxix., fig.l). — Cotyledons resemble 

 those of E. corymbosa, but are slightly smaller. Internal concave 

 border shallower, petiole shorter. Leaves entire, alternate, 

 obtuse, ovate, petiolate. First pr. L4 x 1, petiole LI; second pr. 

 2-7x1 '5, petiole 0*7 cm. Stem and leaves covered with glandular 

 hairs. After the third pair, the leaves become peltate for a 

 few pairs. They have a peculiar bluish-green appearance. Vena- 

 tion a little oblique and open. Leaves broader, but shorter than 

 in E. corymbosa.
