CCLXVI. E. De Beuzevillei Maiden.

In Journ. Roy. Soc. N.S.W., liv, 68 (1920).

FOLLOWING is the original description:—

Arbor ampla plusve minusve glauca; cortice læve, lamellis longissimis decidua, trunci basi asperolamellosa, ligno pallido fere albo, gummi venis; foliis fragrantibus, foliis junioribus orbicularibus ad cordatis, venis secondariis patentibus vel sursum curvatis; foliis maturis lanceolatis, crassis, venis secondariis basi patentibus postquam longitudinalibus; alabastris angularibus fere alatis, operculo conoideo calycis tubo ca. dimidio aequilongo; fructibus polygonalibus, angularibus, piriformibus vel subglobosis, capsula depressa, sessile vel brevissime pedunculata.

A tree of medium or large size, up to 60 feet high, a “White Gum,” more or less glaucous, the young branchlets glandular. Bark smooth, but with usually more or less rough-flaky bark at the butt. Where the rough bark is present it usually ascends the trunk about 5 to 6 feet; the deciduous or smooth portion in long strips, not ribbons, some of the pieces being 30 feet long. Timber pale-coloured, almost white, with gum (kino) veins, with a general resemblance to that of E. coriacea. Foliage fragrant.

Juvenile leaves almost orbicular to cordate, thin, shortly petiolate, secondary veins spreading or curved upwards, no distinct intramarginal vein. Some leaves measured are 9 cm. long by 7 cm. broad.

Mature leaves lanceolate, slightly falcate, with a short blunt point, thick, slightly shining, the secondary veins spreading at the base, thence longitudinal and parallel to the midrib. An average leaf is about 13 cm. long and about 4 cm. in greatest width. There are leaves intermediate in shape, thickness and venation between the juvenile and mature leaves.

Buds remarkably angular by compression, the angles almost winged, peduncles about 1 cm. long, convex to flattened, expanded, especially at the top, pedicels absent or very short, the conoid operculum about half the length of the calyx-tube. Filaments cream-coloured, anthers renantherous.

Fruits polygonal and most of them angled, the angles or ribs persisting until maturity, pear-shaped to sub-globose, sessile or very shortly stalked, walls thick; capsule sunk, 3 or 4-celled.

Type from Jounama Peaks, New South Wales, Wilfrid Alexander Watt de Beuzeville, Assistant Forester, Forestry Commission, December, 1919.

Range.

So far it has only been found on peaks in the Mount Kosciusko district of New South Wales. “Near the summit of Mount Jounama, at an altitude of 5,400 feet almost. Jounama is one of what is known as the Bogong Peaks, in the parish of Jounama, county of Buccleuch, about 30 miles south of Tumut. There is a belt of

these trees about 5 or 6 miles long by about half a mile wide, along the top of the Jounama Peaks. Its lowest level would be between 4,500 and 5,000 feet. The tree is one of the largest in the district. The buds mature in a few weeks, and the fruits set immediately; in other words, it flowers and fruits in the same year.” (de Beuzeville.) (A consequence of the severity of the climate during the greater part of the year.) This species and E. stellulata Sieb. in the same district carry buds and fruits in all stages of maturity during the year.

Affinities.

1. With E. coriacea A. Cunn., var. alpina.

It differs in being a much larger, and, as a rule, a freer growing plant. “Have never seen a form like it before. Tree much like the ordinary E. coriacea, except for it being much more spreading and gnarled, though this might be accounted for by its exposed position at a high altitude.” (de Beuzeville.) It has large, mostly oblique leaves and large angular buds. The fruits are also two or three times as large as those of var. alpina, and usually with two or three faint angles and a more convex rim.

Its affinity with the Tasmanian E. coccifera Hook. f., is more remote.

2. With E. gigantea Hook. f.

The affinity lies in the shape of the juvenile leaves (suckers) and more distantly in the fruits. The foliage of both species is fragrant, with the same kind of odour, but E. gigantea is a rough-barked species, while E. de Beuzevillei is a Gum.

3. With E. tetragona F.v.M.

There is similarity in the polygonal, often quadrangular fruits, which requires a word of caution in case fruits are the only material available.
