CCLXX. E. Pilligaensis Maiden.

In Journ. Roy. Soc. N.S.W., liv, 163 (1920).

FOLLOWING is the original description:—

Arbor mediocris, cortice cana E. hemiphloiae simile et in trunco ramisque persistente; ligno brunneo, fibris tortuosis; foliis junioribus lineari-lanceolatis ca 10 cm. longis et 1·25 cm. latis, utrinque obscuris, venis distinctis sed praeter costam non conspicuis, vena peripherica a margine paullo remota, venis patentibus; foliis maturis angusto-lanceolatis ca 10 cm. longis, 2·5 cm. latis, nitentibus vel obscuro-nitentibus utrinque, venis junioribus foliis similibus; alabastris non angularibus, operculo conico, calyce in pedicillum angustato; antheris E. odoratae similibus, stigma paullo dilata; fructibus parvis conoideis ad subcylindraceis ca 3 mm. longis in pedicellum paullo longiorem angustatis, pedunculo ca 9 mm.; margine distincta valvis plerumque 4, valde immersis.

A medium-sized tree.

Bark.—Whitish grey like that of E. hemiphloia, and persistent as in that species, on the trunk and main branches.

Timber.—Brown coloured and interlocked.

Juvenile leaves.—Linear-lanceolate, say 10 cm. (4 inches) long and say 1·25 cm. (¼ inch) broad, dull on both sides, venation distinct though not conspicuous, except as regards the midrib. Intramarginal vein a little distant from the edge, venation spreading.

Mature leaves.—Narrow lanceolate, say 10 cm. (4 inches) long, and up to say 2·5 cm. (½ inch) broad, shining or dull-shining (egg-shell lustre) on both sides; venation as in juvenile leaves.

Buds.—Not angular, with conical operculum, the calyx tapering into the pedicel.

Flowers.—Anthers very similar to those of E. odorata; the stigma slightly dilated.

Fruits.—Small, conoid to subcylindrical, say 3 mm. (? inch) long, tapering to a pedicel rather exceeding that length, into a common peduncle of 9 mm. (? inch); rim distinct, valves usually four, well sunk.

This tree has received both attention and neglect, because it has been by some looked upon as included in E. Woollsiana R. T. Baker. As I have now no hesitation in saying that it is not included in E. Woollsiana (compare Mr. Baker's figures of that species), and as I am of opinion that it has not been formally described as a species, I offer it as new. Inasmuch as it is so common in the Pilliga Scrub, New South Wales, that the district may be looked upon as a focus of it, the specific name chosen may be useful.

Illustrations.—See Part XI, Plate 51, figures 27–30 of the present work; also my “Forest Flora of New South Wales,” Part XLI, Plate 152, figures B and C, for much larger and better figures. These were all drawn from a specimen collected by me at Narrabri, New South Wales, in November, 1899, and form the type. A photograph block of saplings at Gilgandra, New South Wales (R. H. Cambage) was backed by specimens referable to this new species. All the figures were labelled E. odorata var. Woollsiana.

Synonym.

E. odorata Behr and Schlecht., var. Woollsiana Maiden, as described at p. 32, Part XI of the present work.

Range.

So far as I know, this species is confined to New South Wales and Queensland, but we have much to learn in regard to its range in these, and possibly in other States. It is represented by the following specimens in the National Herbarium, Sydney. The localities quoted are all in the northern half of New South Wales, extending just into Queensland, the two quoted from that State marching with the northern New South Wales localities.

New South Wales.

Mount Boppy (J. L. Boorman, August, 1903). Four and a half miles from Coolabah Railway Station on the way to the old Experiment Farm (J. L. Boorman and J.H.M.). “Mallee Box,” Moondana, Parish Flinders, Nymagee district (Forest Guard E. F. Rogers).

Gilgandra (R. H. Cambage No. 1135, with photo. of a clump of saplings, already quoted). Large shrub or small tree, Dubbo–Gilgandra road, 18 miles from Dubbo (W. Forsyth, No. 2). “Narrow-leaved Box,” Coonamble (E. Taylor).

Castlereagh River (Rev. Dr. Woolls), labelled E. largiflorens by Mueller. “Narrow-leaved Box,” on the plains near Baradine (W. Forsyth, No. 5).

Very common in the Pilliga Scrub, as the following specimens will show:—

Box, slaty smooth bark on branches. Forest Reserve 1,263, Parish Leard, County Nandewar; 45 feet high, girth 54 inches (Forest Guard M. H. Simon). “Narrow-leaved Box.” Bark greyish in colour and rough on trunk, smooth on limbs and of darkish colour. Height 60 feet, diameter 3 to 4 feet. Wee Waa (Forest, Guard T. W. Taylor, No. 14). “White Box,” near Old Wongan Station, Dubbo Creek area (Dr. H. I. Jensen, No. 56). “Gum-topped White Box.” Cuttabri (J. L. Boorman, Dr. H. I. Jensen, Nos. 2, 19). “Narrow-leaved Box.” A tree of 60 feet, fairly straight, Parish Kenebri, County White, Pilliga (E. H. F. Swain, No. 40). A Box, girth 7 feet, Pilliga (E. H. F. Swain, No. 29).

Narrabri, November, 1899 (J.H.M.). The narrow suckered tree defined by me as E. odorata var. Woollsiana. Type of E. Pilligaensis.

“A Box growing on flats, black soil plains, by side of river, medium-sized trees.” Narrabri West (J. L. Boorman). “Narrow-leaved Box. Bark whitish-grey, like that of E. hemiphloia, and persistent as in that species, on the trunk and main branches. I also saw it growing in the Forbes district.” Narrabri (Henry Deane). (I have not seen the Forbes specimens—J.H.M.)




  ― 212 ―

“Narrow-leaved Box.” Moree (W. S. Campbell). In flower only, and at one time considered by me to be E. odorata.

“Apple,” Bingara (E. H. F. Swain, No. 11). “Mallee Box,” Yagobie, between Gwydir and MacIntyre Rivers (E. H. F. Swain, No. 8).

Dark flaky bark. Denman, the most southerly locality known, at all events in the coastal districts (W. Heron, No. 24).

Queensland.

A medium-sized tree, known locally as “Mallee Box,” Inglewood, via Warwick (J. L. Boorman).

“Ribbon Box.” Same growth, size, and bark as Gum-topped Box (E. hemiphloia), but leaves narrow and fruit very small. Very abundant. Wyaga, Goondiwindi district (C. T. White, No. 26).

Affinities.

It is known as “Narrow-leaved Box,” and best deserves this name of all the Boxes. This, combined with the remarkably small fruit, readily separates it from such species. From E. Woollsiana R. T. Baker, E. odorata Behr and Schlecht., E. hemiphloia F.v.M. var. microcarpa, E. conica Maiden, all Boxes, like it, with pale timbers and similar bark, it is distinguished by its very narrow juvenile leaves and usually narrower mature leaves. From E. bicolor A. Cunn., which has narrow juvenile leaves, it is sharply separated by the thick, dark bark and red-brown timber.
