CCLXXXIII. E. adjuncta Maiden.

In Journ. Roy. Soc. N.S.W., liv, 167 (1920).

FOLLOWING is the original description:—

Arbor alta, “Grey Gum,” ligno atro-rubeo. Foliis maturis petiolatis lanceolatis, rectis vel falcatis, venis secundariis patentibus non-prominulis. Alabastris axillaribus, umbellis 3-floris in duobus paribus, pedunculis pedicellisque gracilibus, calycis tubo obconico, operculo rostrato 1 cm. longo. Fructibus hemispherico-conoideis, ca 1 cm. diametro, calycis tubo læve margine distincta, capsulæ valvis valde exsertis.

A tall tree of 70 or 80 feet, with a diameter of 3 or 4 feet (Andrew Murphy); the bark smooth, and somewhat rough in patches, like that of a Grey Gum; timber deep red.

Juvenile leaves.—What are known as “suckers” (adventitious shoots) are not available, but a young seedling has leaves of medium width.

Mature leaves small (as far as the material is available), petiolate, lanceolate, straight or falcate, tapering gradually to the apex, without lustre, secondary veins not prominent, spreading, the midrib and marginal vein pink in colour.

The original material was mislaid. When subsequent search was made for the original trees it was found that the group of three had been destroyed in the widening of the line, and others have not yet been found. The belated description is published now, in the hope that other trees may be traced.

Buds axillary, usually in two pairs of three flowered umbels, peduncles slender, 1 cm. long and more, decurved, pedicels slender, of half that length, calyx-tube smooth, obconical, 5 mm. long. 7 mm. broad, terminating somewhat abruptly in the pedicel; operculum rostrate, 1 cm. long. Anthers long, white, opening in parallel slits, gland at back, versatile.

Fruits hemispherical-concoid, about 1 cm. in diameter, calyx-tube smooth, with distinct domed rim, the valves of the capsule three or four and well exsert.

Range.

Close to the bank of a fresh-water creek, near the eastern side of the railway line, about three-quarters of a mile from Wyee Railway Station, towards Morisset, Wyee is 71 miles north of Sydney, and 33 miles south of Newcastle, New South Wales.

The species has been temporarily lost, so we must postpone further notes as to its range. It has probably been confused with other Grey Gums in well-watered littoral districts of New South Wales and Queensland.

Affinities.

Its position seems to be between E. longifolia, Link and Otto, and E. punctata DC., but to come nearer to the former. The timber seems to be nearer E. longifolia in texture and colour, although that of E. punctata runs it closely. As regards the bark, while E. punctata is consistently a Grey Gum, one may have logs showing that the woolly bark (woolly-butt) of E. longifolia almost disappears, showing bark intermediate between a Grey Gum and a Woolly-butt. E. adjuncta is a Grey Gum.

1. With E. longifolia Link and Otto.

For E. longifolia see Part XX, Plate 86, of the present work. There is similarity in the pink veins of the leaves and in the three-flowered umbels and in the timber. There are differences in the larger leaves of E. longifolia, in the (as a rule) smaller flowers, in the absence or almost absence of exsertion of the valves and in the roughness of the bark.

2. With E. punctata DC.

Originally E. adjuncta was sent as a “bark and timber not to be distinguished from E. punctata.” For E. punctata see Part XXIX, Plates 121, 122, of the present work, where it will be seen that the peduncles and pedicels are thicker, the flowers are more numerous in the umbel, the buds different in shape, and the fruits different.
