E. Flocktoniae Maiden.

  • 133. (Ref. No. C 24.) Desmond, Western Australia (a railway station 26 miles north of Hopetoun on the south coast) (J.H.M., October, 1909). Seedling with two cotyledon leaves and a number of almost linear leaves; all shown not opposite except the two top pairs, but this not-opposite appearance is apparently owing to some leaves having fallen off. (I have, however, a drawing in which this not-opposite appearance is exhibited in an even younger seedling.) Further sowings might be made. Sown 18th September, 1913; drawn early in January, 1914.
  • 134. Same particulars as No. 133. Top of a seedling 18 cm. high. What is drawn shows a tendency to axillary branches; but the lower portion (not drawn) shows a much greater tendency to branch, a pair of branches being in the axils of the first pair of first leaves, and occurring in each of the seven pairs of first leaves (not drawn). One of the branches was 5 cm. long. Drawn 19th January, 1914.
  • 135. Same particulars as No. 133. Two portions of a seedling 1 foot 5 inches high, drawn 12th November, 1914. This seedling shows that the decurrence of the leaves is exhibited early in the life of the plant. (For further particulars and discussion see Part XXXIX, p. 281.) The rachis is quadrangular, as conspicuously shown in E. globulus and other species. It has a rather thick leaf, with the intramarginal vein near to the edge. Both sides are similar in colour.

I have a series of drawings of what I believe to be E. Flocktoniæ which are more glaucous than those already referred to. The leaves are even more decurrent, and in every essential character the seedlings resemble Nos. 133–5. The seeds were received from the Woods and Forests Department of Western Australia, without precise locality, in 1903, labelled E. salmonophloia by mistake, and sown 6th June, 1905. The drawings commenced on 11th July, 1905. It is impossible to say how a slip of this kind occurred, but the result brought to light a remarkable seedling.

E. leptophylla F.v.M.

  • 136. (Ref. No. 102 H.H. 143.) West side of Ballandry, near Griffith, N.S.W. (W. D. Campbell). Seedling with one pair of cotyledon leaves and two pairs of opposite linear first leaves. Sown 20th October, 1919; drawn 16th December, 1919.

Seedling unchanged 23rd March, 1920.

  • 137. Same particulars as No. 136. Seedling, 5½ inches high, ground line not shown, with nine pairs of opposite, narrow-lanceolate, sub-sessile leaves. Drawn 14th April, 1920.

On 1st November, 1920, was still 10½ inches high, branching, but otherwise unchanged.

  • 138. Same particulars as No. 136. Seedling, 8½ inches high; top of seedling drawn 11th October, 1920. Five pairs of opposite, sub-sessile, narrow oblong-lanceolate leaves. Drawn 11th October, 1920.

On 1st November, 1920, this seedling was 10½ inches high, and some of the leaves oblong-ovate.

On 31st January, 1921, this seedling was 15 inches high, and unchanged except some branching.

On 24th May, 1921, this seedling was 23½ inches high, leaves alternate, but otherwise practically unchanged.

  • 139. Same particulars as No. 136. Top of seedling, which was 10½ inches high, drawn 11th October, 1920. A second seedling of the same sowing. Four pairs of leaves nearly opposite, sub-sessile, elongated narrow-lanceolate, exhibiting a tendency to branching in the axils.

On 31st January, 1921, seedling was 13½ inches high, branching on the top.

On 8th March, 1921, was 16 inches high, the leaves glaucous and almost opposite.

On 24th May, 1921, the seedling was 17 inches high, the leaves alternate, but otherwise unchanged.

E. calycogona Turcz.

  • 140. (Ref. No. 8.) Eyre's Peninsula, South Australia. where it is locally known as “Kong Mallee.” (W. J. Spafford). Seedling, showing one pair of cotyledon leaves and five pairs of first leaves opposite, shortly petiolate and oblong-lanceolate (small), not channelled. Sown 26th March 1918; drawn 5th July, 1918.
  • The top 6½ inches of the same seedling drawn on the 7th April, 1919, and provisionally numbered 141, but wa scrowded out. Height 10 inches. All the leaves were shortly petiolate, alternate, ovate-lanceolate, and showed a tendency to branch.
  • 142. (Ref. No. X 3). Yeelanna and Butler, Eyre's Peninsula, South Australia (W. J. Spafford, June, 1917). Seedling, with cotyledon leaves and four pairs of young, opposite, shortly petiolate, lanceolate leaves. Sown 13th December, 1917; drawn 21st March, 1918.
  • 143. Same particulars as No. 142. Seedling with three cotyledon leaves (rare), succeeded by five whorls of triphyllous leaves (rarer), still young. Drawn 22nd March, 1918.

Another seedling of the same batch, drawn the same date, had lost its cotyledon leaves, but exhibited no trace of triphylly in the first leaves.

  • 144. Same particulars as No. 142. Seedling 18 cm. high, cotyledon leaves dropped. The first two pairs of seedling leaves narrow, the third pair broader, tending towards lanceolate and just becoming non-opposite. All the other leaves ovate-lanceolate and alternate. All the leaves, whatever the shape, with short petioles. Drawn 16th May, 1918.
  • 145. Same particulars as No. 142. Seedling 2 feet 3½ inches high, the top 4 inches, say 1 dm., drawn. The leaves all alternate, distinctly petiolate and mostly ovate-lanceolate in shape. Drawn 27th February, 1919.

On 23rd December, 1919, the leaves were unchanged, but the seedling had attained a heigth of 2 feet 8 inches. The leaves of the two stages referred to under No. 145 display a very strong similarity to those of the younger seedling, 141, which has been already referred to as crowded out.
