CCXLVII. E. Baileyana F.v.M.

In Fragm. xi, 37 (1878).

FOLLOWING is a translation of the original:—

A tree, with angular branchlets, leaves scattered, papery, falcate-lanceolate, glaucous green, opaque, densely punctate, veins very fine, moderately spreading, peripheral vein rather distant from the margin, umbels axillary and lateral, solitary, 7–10 flowered, on a slightly compressed peduncle, calyx shortly pedicellate, the tube slightly longer than the semi-ovate or almost hemispherical, rather acute operculum, all the stamens fertile, anthers broadly cordate, fruit globose-urceolate, trilocular, margin of the orifice thin, valves deltoid, shortly exsert.

Moreton Bay, rare. Bailey.

Bark fibrous, persisting not only on the trunk but also on the branches, the inner bark tough and yellow. The timber, according to the discoverer, is yellowish. Leaves 3–5 inches long, ½–1 inch broad, the same colour on both sides, dull, thickly covered with slightly pellucid dots; veins inconspicuous, not closely pinnate. The flower-bearing peduncles about ½ inch long, the fruit-bearing ones double that length. Buds densely capitate, clavate-cylindrical; I have not seen fully developed flowers. Stamens inflexed before expansion. Fruit-bearing pedicels 2–4 lines long. Friut 5–7 lines long and broad, slightly wrinkled-striate, very obtuse at the base; the valves occasionally scarcely extending beyond the mouth of the calyx. Seeds not seen.

Mueller described the species in English in the “Eucalyptographia” with a figure, which, like the description, is erroneous in parts.

Mueller mixed up two trees under the one name. For example, in his “Eucalyptographia” figure, the lower part of the twig bearing the fruits is the true E. Baileyana. The rest of the figure, leaves, buds, and flowers, and of the details (again excluding the fruits and seeds) belong to a Stringybark nearest to E. eugenioides Sieb. The figure, therefore, is a composite one, the twig of E. eugenioides having been prolonged, and the fruits of E. Baileyana having been fitted on to it. In other words, no such plant exists as is figured.

I therefore re-described the species in the following words in my “Forest Flora of New South Wales,” Part XXXV, p. 71:—

Bark.—The bark is hard, thick, rather interlocked, and contains much kino. It is not a typical Stringybark—that is to say, its bark is not soft and fibrous.

Timber.—Of a light-grey colour when fresh, interlocked in grain, very tough, inferior in quality to that of the other Stringybarks (J. L. Boorman.)

Juvenile leaves.—Nearly ovate, not cordate at the base, tapering slightly at the apex to a blunt point or rounded. Common dimensions are 1½ inches broad and 3 inches long. The margin somewhat undulate, the intramarginal vein a considerable distance fom the edge. The under surface nearly white, densely besprinkled with stellate hairs, as also the rhachises. The upper surface bright green, in prominent contrast to the lower surface. This surface is very sparingly besprinkled with stellate hairs, or they may be entirely absent.

Mature leaves.—Lanceolate, symmetrical or falcate, gradually tapering to fine, though not rigid points. Five inches long, with a width in its broadest part of about ¾ of an inch, are common dimensions. The marginal vein close to the margin, or forming a thickening of the same; the lateral veins numerous and fine, parallel, and forming an angle of about 45 degrees with the midrib. Upper surface shiny, under surface paler and dull.

Flowers.—Umbels vary in number, but usually 5 to 7, the common flattened peduncle of about an inch; the flattened pedicels from ¼ to ½ an inch. Anthers small, versatile, with parallel cells and long narrow openings, with a relatively large gland at the back.

Buds.—Pear-shaped, the calyx irregularly toothed; the operculum nearly hemispherical, or with an umbo.

Fruits.—Rather large, globular-urn-shaped, 3-celled; margin of the orifice thinly compressed; valves deltoid, slightly exserted or hardly extending beyond the orifice; seeds without any appendage. (Mueller.) The largest fruits seen by me are about ? of an inch wide, and the same deep.

Range.

The type comes from “Moreton Bay.” More precisely, the locality from which the type was obtained is Eight Mile Plains, a few miles south of Brisbane.

It, however, is also found in northern New South Wales, and its known localities extend from 20 miles south of Grafton, New South Wales, in the south, to the Blackdown Tableland, about 100 miles west of Rockhampton, Queensland, in the north.

New South Wales.

Low, sandy country, about 20 miles south of Grafton. “Trees mostly hollow and ringy,” showing that, as regards this particular locality, it is dying out.

“I do not remember having mentioned to you my meeting with the tree E. Baileyana (Bastard Ironbark) on the Clarence. I found it on some low, sandy country, about 20 miles south of Grafton. The trees I saw were from about 20 inches to 3 feet in diameter, and of medium height—25 to 40 feet to first branch. Bark dark, fibrous, and transversely interlocked, and very hard and tough. Trees mostly hollow or ringy.” (Late Mr. Augustus Rudder.)

Copmanhurst, Clarence River (J. L. Boorman). “Fairly tall trees of 30–50 feet high, with girth measurements of 6–8 feet. The bole is free from branches up to 25–30 feet; is sound and heavy. The bark is thick-fibrous, but perhaps inferior for thatching purposes. The colour of the stem is a distinctive reddish colour, making it

prominent above all other trees in the district. The soil where it grows is of a sandy nature, ridgy, and of a poor quality. It is known locally as Stringybark. The timber is much esteemed locally.”

Between Lawrence (Clarence River) and Casino (Richmond River). (W. Forsyth.)

Queensland.

Eight Mile Plains (F. M. Bailey and others). The type.

Between Sunnybank and Mt. Gravatt. (C. T. White.)

The next locality of which I have a record is approximately 500 miles to the north-west.

“Good development, distribution scattered. Elevation about 2,400 feet. Blackdown Tableland near Dingo, 100 miles west of Rockhampton.” (P. MacMahon, N. W. Jolly.)

It is quite evident that we have much to learn in regard to the range of this species, particularly in Queensland, and it is very probable that a careful investigation of the trees of the Blackdown Tableland would yield interesting and perhaps unexpected results.

Affinities.

1. With E. dichromophloia F.v.M.

The species in the fruit somewhat resembles E. dichromophloia, otherwise it is very different. The true affinity of this species will be better shown when expanded flowers are available. (Original description.)

2. With E. Bowmani F.v.M.

Mueller, “Eucalyptographia,” goes into the supposed differences of these two species at some length, but as (see the present work, Part X, p. 344) we do not know what E. Bowmani is, we may defer consideration of the comparisons until we do.

3. With E. trachyphloia F.v.M.

“… its leaves are paler beneath, and their veins very divergent and copious; the stalklets are thin; the lid is much smaller, and exceeded in width and still more so in length by the tube of the calyx, separating moreover by an irregular rupture and not a clearly defined circumcision; the anthers are ovate, whereas the fruit is much smaller, nearly twice as long as broad, with deeply enclosed valves.” (“Eucalyptographia,” under E. Baileyana.)

4. With E. eugenioides Sieb.

“Finally it may be observed that E. Baileyana exhibits great resemblance to E. eugenioides both in leaves and flowers, although the fruits are so very decidedly different. …” (“Eucalyptographia,” under E. Baileyana.) The comparison with E. eugenioides more particularly arose through the confusion between the two species, as already detailed.

The comparisons with E. Baileyana already referred to for the most part fall to the ground because, in his original description, Mueller described portions of two species, as already explained.

E. Baileyana is a true member of the Eudesmieæ, and it is with species of that series that it can be most suitably compared. Its closest affinity appears to be with E. tetradonta. The matter will be further dealt with when the whole of the Eudesmieæ are passed under review. See Part XLV.
