CCLXXII. E. notabilis Maiden.

In Journ. Roy. Soc. N.S.W., liv, 169 (1920).

FOLLOWING is the original description:—

Arbor mediocris pulchra umbrosa, cortice lamelloso-fibrosa “Mahogany” simile, ligno pallido rectis fibris duro. Ramulis quadrangulatis. Foliis juvenilibus lanceolatis, petiolatis, pallidis, inferiore pagina, venis secundariis fere parallelibus. Foliis maturis crassis, coriaceis, lanceolatis, rectis vel falcatis, penniveniis. Alabastris ad 9 capitulo, pedunculo lato fere sessile, calycis tubo hemispherico ad hemiellipsoides, angulis duobis prominulis. Fructibus fere hemisphericis, ca 7 mm. diametro angulis vel alis duobus, margine distincta, valvis valde exsertis.

A tree of moderate size, say about 50 feet, with a diameter of 4 to 5 feet. It has rich dark umbrageous foliage, and is a handsome species.

Bark flaky-stringy, or fibrous-flaky in young trees. It is rough to the tips of the branches, and the trunk does not display corrugations of the bark. Timber pale-coloured (of the palest brown when freshly cut), straight grained, a good splitter, and possessing a fair degree of tensile strength.

Juvenile leaves.—Young branchlets markedly quadrangular, leaves very thin, pale on the underside, punctate, lanceolate, petiolate (say 10 or 11 cm. long, 3 or 4 cm. broad, with petioles of 1 cm. and more), secondary veins thin, roughly parallel, rather spreading, making angles of 60–80 degrees with the midrib, a few nearly at right angles; intramarginal vein well removed from the edge.

Mature leaves thick, coriaceous, of egg-shell lustre on the upper, but dull on the lower surface, lanceolate, straight or falcate, tapering into a long apex, petiolate, up to 14 cm. long and more, up to 4 cm. in greatest width, with petioles of 2 cm. Venation inconspicuous, the secondary veins penniveined, nearly as parallel and commonly making scarcely a more acute angle with the midrib than the Corymbosæ; the intramarginal vein not far removed from the edge.

Buds up to nine in the head, on a broad strap-shaped peduncle of 1 cm. or less, sessile or on pedicels of ·5 cm., each commonly with a double operculum; calyx-tube hemispherical to hemiellipsoid, with two angles or ribs sometimes so prominent as to be winged; operculum hemispherical to conoid, up to 7 mm. in diameter and sometimes exceeding that of the calyx tube.

Anthers white, opening in parallel slits, the two cells usually cohering to the tips; versatile; large gland at the back.

Fruits almost hemispherical, about 7 mm. in diameter, often with two or more angles or wings; rim well defined; the calyx valves three or four, broad at the base, and the tips well exsert.

Type.—Glenbrook, Blue Mountains, New South Wales. (R. H. Cambage and J.H.M.)

Illustrations.—The new species is figured as intermediate between E. resinifera and E. pellita in the present work, Part XXX, Plate 125, figs. 7, 8, 9. We there have a juvenile leaf, mature leaf, buds with hemispherical and conoid opercula, anthers and fruits.

Synonym.

Recorded as the Blue Mountains form of those intermediate between E. pellita F.v.M. and E. resinifera Sm. See present work, Part XXX, pp. 216, 217.

Range.

Confined to New South Wales so far as we know at present, and to the vicinity of the lower slopes of the Blue Mountains, but owing to wide-spread confusion with E. resinifera we have much to learn of its range. It has only been recorded so far from the Lower Kurrajong and Glenbrook to Faulconbridge.

Following are specific localities:—Lower Kurrajong, one of the lower slopes to the Blue Mountains (J.H.M.); Glenbrook (R. H. Cambage, J.H.M., J. L. Boorman); Lapstone Hill to Springwood (R. H. Cambage and J.H.M.); Springwood (J. L. Boorman); North Springwood (R. H. Cambage and J.H.M.); Faulconbridge (J.H.M.).

Affinities.

1. It is one of the few species, of which E. gomphocephala DC. is the most notable, which have an operculum of diameter greater than the calyx-tube, giving it an overhanging appearance.

2. The anthers of E. notabilis and E. canaliculata are to all intents and purposes alike. Affinity to each other is thus indicated, and also that they belong to the same group, which includes E. punctata, E. resinifera, and E. pellita.

3. With E. resinifera Sm. (and E. pellita F.v.M.).

The position of E. notabilis seems to be nearest to these two species, but closer to the former in some respects. The figures and remarks on this association have already been referred to. The bark is that of a “Mahogany,” but the paleness of the timber of E. notabilis at once separates it from these two species.
