Shrub or small tree, to 25 ft.: leaves lanceolate or ovate-lanceolate, rather obtuse, mostly 2-4 in. long; veins inconspicuous: calyx-tube ribbed in the common forms; lid thick, hemispheric or short-conic, often abruptly beaked; stamens all inflected in the bud; anthers ovate-oblong, opening by parallel slits: fruit ovoid-cylindric, about 3/4in. across; valves often slightly exserted. F.v.M. Eucal. 5:6. Maiden, Crit. Rev. Eucal. 13, 15. - Australian deserts: one of the "mallee."
Variety angulosa, Benth. (E. angulosa, Schau.). Calyx-tube and lid prominently angled or ribbed, but varying much in this respect as well as in size of flowers and fruits Maiden, Crit. Rev. Eucal. 14.
Tree, to 100 ft., with angular branchlets: leaves lanceolate, acuminate, elongated: lid conical, about as long as the tube, both longitudinally streaked; outer stamens flexuous in bud but only the inner ones incurved; anthers broadly ovate, opening by parallel slits: fruit ovoid-cylindric, truncate, about 3/4in. across, the caps, sunk and valves well inclosed. F.v.M. Eucal. 4:6. - A profuse bloomer. Timber heavy, hard, and durable; well adapted for sawing but not easily split.
Tree, 100 ft. or less high: bark deciduous, smooth, grayish white: leaves lanceolate, falcate, mostly 4-6 in. long: flowers only 1-3 and sessile in the umbels; lid shortly conical; stamens about 1/2in-long; anthers ovate-oblong, opening by parallel slits: fruit depressed-globular, thick and hard, 3/4 - l in. across; rim convex, continuous with the thick obtuse incurved valves. F.v.M. Eucal. 6:3. Maiden Crit. Rev. Eucal. 78 (figs. 4-8).
Tooart Tree. Tree, 120 ft. or less high: bark persistent, rough but not stringy, becoming dark: leaves thick, narrowly acuminate, pale green: flowers usually 3-5, sessile; lid globose, very hard and thick; stamens 3-4 lines long; anthers opening by parallel slits: fruit turbinate; rim broad and convex, rounded to the incurved valves. F.v.M. Eucal. 7:4. - Easily distinguishable by the broad lid. Wood of a pale yellowish color: remarkable for hardness and strength, heavy, the grain close and twisted: shrinks but little and does not check while seasoning: suitable for large scantlings and for use where exposed to great heat, as in engine-rooms: one of the strongest woods known. Grows both along the coast and in the dry interior valleys: one of the most alkali-resistant species.
Desert Gum. Tree, 100 ft. or less: bark gray, persistent, rough, but not deeply furrowed: leaves broadly to narrowly lanceolate, mostly 3/4-2 1/4in. wide: peduncles 1/3 - l in. long; pedicels short; lid conical, not beaked, about as long as calyx-tube; stamens 3-4 lines long; anthers opening by parallel slits: fruit broadly turbinate, 4-5 lines across; rim only slightly ascending. F.v.M. Eucal. 10:8. - Stands drought and extremes of temperature better than most other species: endures minimum temperatures of 15-18°: suitable for most situations in the S. W.: successfully used as an avenue tree and for windbreaks at Fresno, Calif. Timber probably of value only for posts and for fuel.
Straggly shrub, or tree to 70 ft.: bark rough, persistent, fragile: leaves ovate to lanceolate, 2 1/4 - 4 1/2 in. long, seldom over 3/4in. wide: peduncles 1/4- 1/2in. long; pedicels 0; lid conical, often twice as long as calyx-tube; anthers very small, globular, opening by pores which become longitudinal slits: fruit broadly turbinate or globose, 3-4 lines across; valves awl-shaped. F.v.M. Eucal. 10:3. Maiden, Crit. Rev. Eucal. 63 (figs. 1-12).
Manna Gum. Plate XXXIX. Graceful tree, to 300 ft., the branchlets pendulous: bark either persistent, roughish, and dark-colored (never fibrous), or deciduous, very smooth, and grayish white: seedling leaves lanceolate; mature leaves lanceolate, acuminate, somewhat falcate: flowers usually 3, rarely 6-8, sessile or on very short pedicels; lid semi-ovate, mostly short-pointed; stamens about 3 lines long; anthers ovate, opening by parallel slits: fruit subglobose-truncate, 3-5 lines across; rim flat or rounded; valves triangular, acute. May-Aug. F.v.M. Eucal. 10:10. G.C. III. 4:597 - A hardy species, grown as far north as Chico, Calif.: ranks next to E. globulus in rapidity of growth. Timber not so strong as that of many other sorts but of average value for fuel, and can be grown under conditions in which more valuable species would not survive or would make only an inferior growth. A good bee tree.
Plate XXXIX. Eucalyptus viminalis in California.
Apple-scented Gum. Tall branching tree, with dense drooping foliage: closely related to E. viminalis, and distinguishable from the latter, when this has more than 3 flowers in an umbel, by the fibrous bark, roundish seedling leaves and somewhat smaller flowers: pedicels almost 0; buds angular; lid almost hemispherical, or shortly and bluntly conical. Feb. - May. F.v.M. Eucal. 4:9.
Bark rough, "very woolly:" seedling leaves linear-lanceolate, slightly cordate, strictly opposite; mature leaves narrow, lanceolate: flowers 4-8, distinctly pedicelled; buds ovoid, smooth, very small: fruit semi-ovate, scarcely 3 lines across. - Related to E. viminalis and to E. Stuartiana: distinguished from the latter by the smooth slender-pedicelled buds and from both by the smaller flowers and fruits
