In Journ. Roy. Soc. N.S.W., liv, 48 (1920), with Plate 1.

FOLLOWING is the original description:—

ARBOR alta quadraginta vel quinquaginta pedes, trunci diametrum unciarum duodeviginti ad duo pedes habens.

Folia matura.—Linearia-lanceolata circiter sex ad quattuordecim cm. longa, octo mm. ad 15 cm. lata, cum apicibus directis vel uncis, interdum leviter falcata, utrobique cinerose viridia, glabrosa, costa media clara, venae laterales aliquanto obscurae et dispositae angulo circiter 45° ecosta, margines plerumque quasi nervi vena intra marginem juxta extremitatem, olei glandulae parvae sed numerosae, petiolus a quinque mm. ad unum cm. longus.

Gemmae globosae, tubus calycis hemisphericalis duo mm. longus, diametrus quattuor mm. habens, operculum simile tubo calycis, terminatum cuspide brevi circiter ·5 mm. longa, pediculi circiter quinque mm. longi, pedunculi teretes a quinque mm. ad 1·1 cm. in parte intera paniculae.

Flores pedicellati, umbellae in paniculis terminalibus vel nonnullae in axillis superioribus, cum floribus a tribus ad septem, antherae parvae patentes late laterale, glandula a tergo filum a fundamento.

Fructus hemisphericales tres ad quattuor mm. longi, diametrum a sex ad septem mm. habentes, ora excitata, circiter 1·5 mm. lati, valvae exsertae, pedunculi a quinque mm. ad 1·2 cm. longi.

Cortex dura, aspera et sulcata.

Lignum rubrum, durum et durabile, consuetissimum in fodinis apud “Chillagoe.”

A tree of 40–50 feet high, with stem diameter of 18 inches to 2 feet.

Mature leaves linear-lanceolate, from about 6–14 cm. long, 8 mm. to 1·5 cm. broad, with straight or hooked points sometimes slightly falcate, greyish-green on both sides, glabrous, midrib distinct, lateral veins rather obscure, and arranged at an angle of about 45 degrees with the midrib, margins usually nerve like, intramarginal vein close to the edge, oil glands small but numerous, petiole 5 mm. to 1 cm. long.

Buds globular, calyx-tube hemispherical, 2 mm. long, 4 mm. in diameter, operculum similar to calyx-tube, terminating in short point about ·5 mm. long, pedicels about 5 mm. long, peduncles terete, 5 mm. to 1·1 cm. in the lower portion of the panicle.

Flowers pedicellate, umbels in terminal panicles or some in the upper axils, with three to seven flowers, anthers small, opening widely laterally, gland at back, filament at base.

Fruits hemispherical, 3–4 mm. long, 6–7 mm. in diameter, rim raised, about 1·5 mm. broad, valves exserted, peduncles 5 mm. to 1·2 cm. long.

Bark hard, rough and furrowed.

Timber red, hard and durable, much used in the Chillagoe mines.

The species blooms in March, and I am indebted to Miss Ethel K. Maitland for flowers.

Reversion (“sucker”) foliage.—Ovate-lanceolate, 3–7 cm. long, 5 mm. to 2 cm. broad, so far as seen.

Seedlings.—Hypocotyl terete, red, 3 mm. to 1 cm. long, 1 mm. thick at base, glabrous.

  ― 234 ―

Cotyledons obtusely quadrilateral to reniform, entire, 2·5–3 mm. long, 4–7 mm. broad, upperside green, underside red; petiole 3 mm. long.

Stem brownish-red in lower portion, brownish-green in upper part.

Seedling foliage opposite for about two or three pairs, entire, glabrous, linear; petiole 2–4 mm. First pair 1·6–2·4 cm. long, 1–2 m.m broad, upperside green, underside purple; leaves Nos. five to ten up to 5 cm. long, 2–3 mm. broad.

A seedling about one foot high has an opposite pair of nodules or swellingsnote about the axils of the cotyledons or the first pair of leaves.

The species is named in honour of Sir William Portus Cullen, K.C.M.G., M.A., LL.D., Chief Justice of New South Wales and Chancellor of the University of Sydney, who has done much to encourage the preservation of our native flora.


It is confined to North Queensland, so far as we know at present.

Alma-den, 121 miles by rail westerley from Cairns, tropical Queensland, about 1,600 feet above sea-level, growing on granite formation containing about 68–70 per cent. silica, and known as Ironbark. (No. 3,905, collected August, 1913.) Mr. J. H. Maiden informs me that he received an incomplete specimen of this species from Chillagoe in 1911. (Original description.)


Its closest affinity appears to be with E. crebra F.v.M., which it resembles in bark, timber, and mature leaves, but differs in the shape of buds and fruits, and in the seedling foliage. It also resembles E. paniculata Sm., in its bark, but differs in the timber and other characters.
