Description.

E. marginata, Sm.

Trans. Linn. Soc. vi, 302 (1802). B.Fl. iii, 209.

FIGURED and described in “Eucalyptographia.” See also Diels and Pritzel, Engler's Jahrb., 1904, p. 438.

A full account of its economic uses will be found in Maiden's “Useful Native Plants of Australia” (1889).

Following is the original description:—

Marginata, operculo conico magnitudine calycis, umbellis lateralibus, foliis ovatis margine incrassatis. E. marginata, Donn. Herb. Cant. ed. 2. 101 (?)

Mr. Aiton favoured me with specimens of this plant three years ago from Kew Gardens. The seeds were brought from Port Jackson. Its leaves agree very much in form with those of E. robusta (next to which it ought to be placed), but the foot-stalks are shorter, veins more prominent, and the margin more thickened, somewhat cartilaginous, and reddish. The umbels are solitary, axillary, and simple. Flowers scarcely one-third the size of the robusta, and their covers are neither broader than the calyx, nor longer; neither are they contracted in the middle. The flowers much resemble those of my E. pilularis, but the leaves are totally different.

Aiton, Hortus Kewensis, iii, 192, calls it “Thick-edged Eucalyptus,” and stated that it was introduced to Kew, in 1794, by seeds obtained from Archibald Menzies, Esq.

Menzies was with Captain Vancouver, who visited South-western Australia, and discovered King George's Sound in 1791. No other portion of Australia was visited by the expedition, and Smith's statement that the seeds came from Port Jackson is probably a mere slip of the pen or a misunderstanding of what Aiton told him. The matter is also discussed by Mueller (Eucalyptographia) under E. marginata, and there is no doubt that E. marginata, Sm., is the West Australian Jarrah.

Synonyms.

1. E. pedicellata, R.Br. MSS. or “Archd. Menzies”—perhaps as collector only—in Herb. Brit. Museum.

2. E. floribunda, Hügel, Enum. Pl. Hügel, p. 49 (1837).

Type from “Swan River.”

3. E. hypoleuca, Schauer in Lehmann's Pl. Preiss. No. 131 (1844). Preiss. No. 226.

The type came from Wuljenup, district of Plantagenet.

4. E. Mahogani, F.v.M. Fragm. ii, 41 (1860).

Kalgan River, Oldfield. Leaves rather thick.

I have examined types of all of the above.

Drummond's 85 (5th Coll. ?) has rather broad leaves and is in flower only.

Drummond's 185 (5th) “Swan River to Cape Riche” has small leaves, shiny and coriaceous.

The original pronunciation of the well-known name “Jarrah” is “Yarrah.”

Mueller quotes Augustus Gregory as giving “Jerrile” as the aboriginal name; Dr. A. Morrison gives another, viz., “Maalock.” Two other species have been sent to me from Western Australia under the latter name.

The thickened margin of the leaf affords a useful diagnostic character, but it is not an infallible guide.

The seedling leaves are remarkable and have not been previously described. Mr. A. G. Hamilton collected the specimen figured (fig. 1, pl. 40) at Woodlupin Creek, W.A.

The cotyledon leaves are nearly reniform, and when dried are 1½ inch in greatest width; width of the lamina from the attachment of the petiole continued until the margin of the lamina is reached is 1 inch; length of petiole 7/8 inch. The cotyledon-leaves and intermediate leaves are glandular—hairy with reddish hairs, lanceolate, and the base of the lamina comes below the point of attachment of the petiole to the lamina.

One of the best known of Australian timber-trees, partly because it is more gregarious than those of most other species of the Australian States. It is a very valuable asset of the Western State, and one of which she can reasonably be very proud.

The bark is rough, not a true Stringybark, but while fibrous it is flaky, furrowed, and somewhat dense in texture.

It is a species with a wide range in Western Australia, and I have nothing to add to the range indicated in “Eucalyptographia.”
