CCLXXXII. E. Jutsoni Maiden.

In Journ. Roy. Soc. N.S.W., liii, 61 (1919).

FOLLOWING is the original description:—

Frutex parvus ramulosus circiter 6–8 altus, trunco tenue. Ramulorum apicibus planis mox teretibus. Foliis maturis brevissime petiolatis, angusto-linearibus, 7.5–9 cm. longis, crassis, duris venis inconspicuis. Pedunculis brevissimis vel absentibus 2–4 floris; calycis tubo conoideo operculo acuminato conoideo æquilongo. Antheris E. angustissimœ similibus. Flores non vidimus.

“A small, thin-stemmed, branching-from-the-root-gum, about 6 to 8 feet high on the average. White flowers, yellow pointed buds. Ants very numerous on the bark” (J. T. Jutson). Branchlets flattened at the tips, but soon becoming terete.

Juvenile leaves not seen.

Mature leaves very shortly petiolate, narrow linear, acuminate, slightly twisted, 7.5–9 cm. (say 3–3½ inches) long, wiry, thickish and tough, the veins inconspicuous, often channelled at the inconspicuous midrib.

Peduncles axillary, very short or absent, flattened, each with two to four flowers.

Buds sessile or tapering into a short, flattened pedicel-like process, the calyx-tube conoid, and of the same length as the acuminate conical operculum.

Flowers.—Stamens inflected in the bud, anthers renantheroid (i.e., somewhat resembling the Renantheræ), and apparently similar to those of E. angustissima. Style long, the stigma scarcely thickened, the ovary conical.

Fruits not seen.

Type from Comet Vale, W.A. (John Thomas Jutson, No. 216. Formerly Geological Surveyor on the staff of the Geological Survey of Western Australia.)

Range.

It is only known from Comet Vale, a township on the railway line 63 miles north of Kalgoorlie, Western Australia.

Affinities.

1. With E. angustissima F.v.M.

Its closest affinity appears to be with the imperfectly known E. angustissima. See the present work, Part XIX, with Plate 84.

E. Jutsoni appears to be a coarser plant than E. angustissima, and its conoid or tip-cat buds are quite different in shape to those of fig. 7a, which has very short, though distinct, non-tapering pedicels. Fruits of 8b, as depicted, could not result from the flowers of E. Jutsoni. The anthers of the two species may not be dissimilar, but I have not seen ripe ones of E. angustissima. After the most careful consideration I am quite satisfied that, although the two species present some points of resemblance, they are distinct.

2. With E. oleosa F.v.M., var angustifolia Maiden.

This is a narrow-leaved form of the species, figured at fig. 17, Plate 65 (the type), with other specimens referred to this form, viz., fig. 18, Plate 65, and fig. 1. Plate 66, with figs. 2 and 3, Plate 66, perhaps belonging to it.

The type of var. angustifolia=E. socialis F.v.M., and it differs from E. Jutsoni in the broader, more distinctly veined leaves, and in the number of flowers in the head. Incidentally it may be pointed out that the buds figured at fig. 1b, Plate 66, display great similarity to those of typical E. angustissima (fig. 6a, Plate 84).
