CCLXIII. E. Kybeanensis Maiden and Cambage.

In Journ. Roy. Soc. N.S.W., xlviii, 417 (1914).

FOLLOWING is the original description:—

Arbor Mallee similis, 6–10' alta, caulibus lævibus viridibus, ligno pallido. Folia juvena lanceolata circiter 6 cm. longa, 1 cm. alta, non-glauca, subtus pallidiore-virentia, margine crassata, costa media prominente, venis lateralibus prominentibus et fere pinnatis. Folia matura coriacea, lanceolata circiter 6–8 cm. longa, 1·5 cm. alta. Alabastra operculis hemisphericis diametro circiter conoideo calycis tubo dimidio equilongis. Flores renantheri. Fructus sessiles, ad 7 in capito, fere hemispherici, diametro fere 1 cm., orificio leniter rotundati, valvarum apicibus orificio aequis.

Species cum E. stricta affinitate trahitur, fructibus autem maxime diversis et E. capitellatœ Sm. similibus, qua magna “Stringybark,” est.

Of mallee-like growth, 6 to 10 feet high, with smooth, greenish stems 1½ inches in diameter. Timber pale coloured.

Juvenile leaves.—Lanceolate, about 6 cm. long by 1 cm. broad as the alternate stage is reached, very shortly petiolate, non-glaucous, of a brighter green on the underside. Margin thickened. Midrib prominent and raised, showing a depression on the upper page of the leaf, the lateral veins prominent and roughly pinnate, intramarginal vein well removed from the edge.

Mature leaves rather coriaceous, lanceolate, about 6–8 cm. long by 1·5 cm. broad, erect, shortly petiolate, equally green on both sides. Veins fairly prominent and spreading from the base; intramarginal vein a considerable distance from the edge.

Buds.—Externally rough in texture, operculum hemispherical, the diameter about half the length of the conoid calyx-tube.


Fruits.—Sessile, up to seven in the head. Nearly hemispherical, nearly 1 cm. in diameter, rim broad and reddish-brown, gently domed, tips of valves flush with the orifice.

The above was drawn up from the type, collected at Kybean on the Monaro.

Following is a description of a specimen from Blackheath, Blue Mountains, N.S.W., designated as “C,” and looked upon by us as a hybrid of E. stricta Sieb. It is briefly referred to in Part IX, p. 283, of the present work.

“C.—A sapling tree, say 4 inches in diameter and 12 feet high. One small clump also seen.

Juvenile leaves.—Not seen in the earlier stage, but in what may be termed the intermediate stage. In that stage they are oval or oblong, and say 1½ inch long by ½ inch broad and profusely dotted with oil glands.

Mature leaves bright green, rather coriaceous. Veins fairly prominent, and spreading from the base; intramarginal vein a considerable distance from the edge. Tips of the leaves hooked as a rule. Reminds one of foliage of E. stricta, amongst which it grows, though the venation is probably more prominent than that of E. stricta.

Buds numerous, pointed and in heads, giving it a stellate aspect. Hardly so clavate as those of E. stricta, but not seen ripe. Four to ten in the umbel.

Flowers.—Expanded ones not seen.

Fruits in dense heads, the common peduncle up to a quarter of an inch, pedicels absent. Individual fruits rarely hemispherical, slightly compressed at the base, rim broad and reddish-brown, slightly domed, tips of valves flush with the orifice.

Bark smooth, very long ribbons.

Timber pale-coloured.

Affinities.—The surrounding species are E. stricta Sieb.; E. Siebeviana F.v.M.; E. Moorei Maiden and Cambage; and E. Gunnii Hook. f. var maculosa Maiden (E. maculosa R. T. Baker). It has already been pointed out that the foliage resembles that of E. stricta. The buds exhibit slight resemblances at least to E. stricta and to E. Gunnii var. maculosa, particularly to the former, but the affinity of the fruit is not at present obvious, though they are suggestive of some forms of both E. capitellata and E. eugenioides, to which trees our plant has otherwise not the slightest resemblance, and it may turn out to be a good species.” (Proc. Linn. Soc. N.S.W., xxx, 201, 1905.)


Confined to New South Wales, so far as we know at present, but it may be expected to be found in north-eastern Victoria.

The type grew on sandy conglomerate formation at Kybean, amongst Casuarina nana Sieber, near the Kydra Trigonometrical Station, on the Great Dividing Range, 4,000 feet above sea-level, 16 miles easterly from Nimitybelle, near Cooma (R. H. Cambage, 4th November, 1908.)

The plant already referred to at “C” was collected at Blackheath in a high part of the Blue Mountains.


1. With E. stricta Sieb., and other species.

Unfortunately the material of E. Kybeanensis is scanty, so that the last word has not been said in regard to its relationships. It is shrubby, almost Mallee-like. In this respect and to some extent in the seedlings, it has relations to E. stricta. In the somewhat straight venation of the juvenile leaves it shows affinity to the E. coriacea group, and in the fruits to the E. capitellata group. It certainly requires further investigation.
