55. Amygdalina, Labill

Peppermint Gum. Tree, the tallest of the genus (var regnans): bark persistent on trunk and lower branches, fibrous: leaves lanceolate, not noticeably oblique at base, 2-4 in. long; veins oblique; oil-dots large, not very numerous: flowers many and crowded in the umbels; buds clavate, often rough; lid hemispherical, very obtuse, shorter than the calyx-tube; stamens under 2 lines long; anthers kidney-shaped, opening by divergent slits: fruit hemispheric or shortly ovate, truncate, about 1/4in. across; rim flat or slightly concave; valves flat or slightly protruding. F.v.M. Eucal. 5:1. B.M. 3260. B.R. 947 (as E. longi-folia). G.C. III. 6:16. R.H. 1902, p. 83. - Timber of inferior durability and strength. Foliage with odor of peppermint; far richer in oil than any other eucalypt.

Variety numerosa, Maiden (E. Andreana, Naudin). Flowers very numerous, often over 20 in the umbel.

Variety regnans, F. v. M. (E. regnans, F. v. M.). Giant Gum. Very tall tree (325 ft. or less high): bark usually smooth, whitish, fibrous only near the base: leaves large, broad-lanceolate, especially those on seedlings broader than in typical E. amygdalina; oil-dots very fine, numerous: fruit usually conoid. Maiden, Crit. Rev. Eucal. 33. - Earlier reports of 400-500 ft. for this tree were erroneous (see Melbourne Argus for March 23, 1904, Maiden, Crit. Rev. Eucal. p. 183, and G.C. III. 47, p. 69).

Variety angustifolia, F. v. M. (E. linearis, Dehnh.). Graceful, spreading tree: branchlets drooping: leaves very narrow: flowers numerous in the umbel. Jan. - Apr., and more or less throughout the year. Maiden, Crit. Rev. Eucal. 30 (fig. 5).

56. Risdonii, Hook. F

A beautiful glaucous-foliaged tree 20-50 ft. high, the branches somewhat pendulous: bark flaking off, smooth, not fibrous: early leaves cordate, connate in pairs; later leaves either opposite and ovate or alternate and broadly lanceolate, not very oblique at base; veins oblique: buds, flowers, and fruit as in E. amygdalina but slightly larger. Maiden, Crit. Rev. Eucal. 32 (fig. 1). - A valuable ornamental: all the leaves commonly opposite and connate.

57. Obliqua, L'Her

(E. fissilis, F. v. M.). Tall tree: bark persistent even on the branches, grayish, very stringy but rather soft and fragile: leaves thick, very oblique at base, 4-6 in. long; veins very oblique: lid hemispherical, depressed or somewhat pointed, shorter than the tube; stamens fully 3 lines long, opening by diverging slits: fruit somewhat pear-shaped, truncate, slightly contracted at orifice, 1/4-1/2in. across; rim broad and concave: caps, well sunk. March-Aug. F.v.M. Eucal. 3:5. Maiden, Crit. Rev. Eucal. 5-8 Will grow on poor soil but does not endure severe drought. Much valued in Austral. for bees: wood used only for cheap, rough work.

58. Stellulata, Sieb

Small tree: bark becoming black and furrowed, deciduous in layers, smooth above: leaves elliptic or lanceolate, 2-4 in. long; principal veins almost parallel to the midrib: flowers very small, numerous; buds ovoid, in star-like nearly sessile umbels; lid conic, acute, about equaling the tube; stamens under 2 lines long; anthers reniform, opening by divergent slits: fruit nearly globose, about 2 lines thick. F. v.M. Eucal. 6:9. Maiden, Crit. Rev. Eucal. 25. - Timber of but little value; scarcely used except for fuel.

59. Coriacea, A. Cunn

(E. pauciflora, Sieb.). Tree, often tall, with spreading branches and slender somewhat pendulous twigs: outer bark deciduous; inner bark smooth, pale gray: leaves ovate-lanceolate or lanceolate, 4-8 in. long, thick, smooth; lateral veins almost parallel to the midrib: flowers 5-10; buds club-shaped; umbels distinctly peduncled; lid hemispheric, obtuse or with a short point, twice or thrice shorter than the tube; stamens 2-3 lines long; anthers reniform, opening by divergent slits: fruit pear-shaped, truncate, 3-4 lines thick. Nov. - Feb. F.v.M. Eucal. 3:6 (as E. pauciflora). Maiden, Crit. Rev. Eucal. 26, 27, 28 (figs. 1, 2). - A high-mountain tree and one of the hardiest species. Cattle browse on the foliage in seasons of drought: timber used for fuel and fences; warps badly. Trees sometimes badly affected with scale.

60. Corynocalyx, F. V. M

Sugar Gum. Fig. 1428. Tree, to 120 ft.: bark smooth: leaves elongate-lanceolate; veins oblique: lid almost hemispheric, projecting beyond the calyx-tube; stamens 2-3 lines long; anthers short-oblong, opening by distinct parallel slits: fruit almost egg-shaped, nearly 1/2in. long by 3-4 lines thick; rim thin; caps, deeply sunk. June-Nov. F.v.M. Eucal. 2:2. G.C. II. 12:593. - A valuable drought-resistant species but does not endure temperatures below 20-25°. Timber close-grained and hard, of a yellowish white color: very durable underground: grown in Calif, for railway ties. An ornamental tree used for roadside planting in S. Calif.: affords much bee pasturage.

61. Buprestium, F. V. M

Shrub, to 20 ft.: leaves narrow, acute, 2-3 in. long: lid hemispherical, obtuse, shorter than calyx-tube; stamens 2-3 lines long; anthers opening by short divergent slits: fruit nearly globular, the orifice much contracted, 3/4-l in. across; rim depressed. July-Oct. F.v.M. Eucal. 6:1. - Valuable for bees.

62. Diversicolor, F. V. M

(E. collosea, F. v. M. E. diversicolor variety collosea, Hort.). Karri. Fig. 1429. Very tall symmetric tree: bark smooth, white: leaves dark green and shining above; veins very diverging: lid obtusely conical, not wider than calyx-tube; stamens 4 lines long; anthers ovate, opening by parallel slits: fruit ovoid-truncate, about 1/2in. long by 4-5 lines thick; rim rather thick; caps. deeply sunk. Feb. - May, and again in Nov. F.v.M. Eucal. 5:4. - Thrives near the coast but does not endure well the dry heat of the interior: too tender for the San Joaquin Valley. A rapid grower, profuse bloomer, and considered a good tree for bees. Timber very hard, durable, of a light red color, and takes a fine polish: suitable for furniture, wagon work, ties, and general construction.
