EUCALYPTUS

long; anthers ovate, opening by parallel slits: fr. 

 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. 



53. Stuartiana, F. v. M. 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 fls. in an umbel, by the 

 fibrous bark, roundish seedling Ivs. and somewhat 

 smaller fls.: pedicels almost 0; buds angular; lid almost 

 hemispherical, or shortly and bluntly conical. Feb.- 

 May. F.v.M. Eucal. 4:9. 



54. Macarthuri, Deane & Maiden. Bark rough, 

 "very woolly:" seedling Ivs. linear-lanceolate, slightly 

 cordate, strictly opposite; mature Ivs. narrow, lanceo- 

 late: fls. 4-8, distinctly pedicelled; buds ovoid, smooth, 

 very small: fr. semi-ovate, scarcely 3 lines across. 

 Related to E. viminalis and to E. Stuartiana: dis- 

 tinguished from the latter by the smooth slender- 

 pedicelled buds and from both by the smaller fls. 

 and frs. 



55. amygdalina, Labill. PEPPERMINT GUM. Tree, 

 the tallest of the genus (var regnans) : bark persistent 

 on trunk and lower branches, fibrous: Ivs. lanceolate, 

 not noticeably oblique at base, 2-4 in. long; veins 

 oblique; oil-dots large, not very numerous: fls. 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: fr. hemispheric or 

 shortly ovate, truncate, about 34 m - 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. 



Var. numerdsa, Maiden (E. Andreana, Naudin). Fls. 

 very numerous, often over 20 in the umbel. 



Var. regnans, F. v. M. (E. rfynans, F. v. M.). 

 GIANT GUM. Very tall tree (325 ft. or less high): 

 bark usually smooth, whitish, fibrous only near the 

 base: Ivs. large, broad-lanceolate, especially those on 

 seedlings broader than in typical E. amygdalina; oil- 

 dots very fine, numerous: fr. usually conoid. Maiden, 

 Grit. Rev. Eucal. 33. Earlier reports of 400-500 ft. 

 for this tree were erroneous (see Melbourne Argus for 

 March 23, 1904, Maiden, Grit. Rev. Eucal. p. 183, and 

 G.C. III. 47, p. 69). 



Var. angustifdlia, F. v. M. (E. linearis, Dehnh.). 

 Graceful, spreading tree: branchlets drooping: Ivs. very 

 narrow: fls. numerous in the umbel. Jan.- Apr., and 

 more or less throughout the year. Maiden, Grit. Rev. 

 Eucal. 30 (fig. 5). 



56. Rfsdonii, Hook. f. A beautiful glaucous-foliaged 

 tree 20-50 ft. high, the branches somewhat pendulous: 

 bark flaking off, smooth, not fibrous: early Ivs. cordate, 

 connate in pairs; later Ivs. either opposite and ovate 

 or alternate and broadly lanceolate, not very oblique 

 at base; veins oblique: buds, fls., and fr. as in E. 

 amygdalina but slightly larger. Maiden, Grit. Rev. 

 Eucal. 32 (fig. 1). A valuable ornamental: all the 

 Ivs. 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: Ivs. 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 



Eucalyptus diversicolor. ( X H) 

 No. 62. 



diverging slits: fr. somewhat pear-shaped, truncate, 

 slightly contracted at orifice, %-}4in. across; rim 

 broad and concave: caps, well sunk. March-Aug. 

 F.v.M. Eucal. 3:5. Maiden, Grit. 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: Ivs. 

 elliptic or lanceolate, 2-4 in. long; principal veins almost 

 parallel to the midrib: fls. 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: 

 fr. nearly glo- 

 bose, about 2 

 lines thick. F. 

 v.M. Eucal. 6:9. 

 Maiden, Grit. 

 Rev. Eucal. 25. 

 Timber of but 

 little value; 

 scarcely used except for 

 fuel. 



59. coriacea, A. Cunn. 

 (E. paudfldra, Sieb.). Tree, 

 often tall, with spreading 

 branches and slender 

 somewhat pendulous twigs : 

 outer bark deciduous; 

 inner bark smooth, pale 

 gray: Ivs. ovate-lanceolate 

 or lanceolate, 4-8 in. long, 



thick, smooth; lateral veins almost parallel to the mid- 

 rib: fls. 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: fr. pear-shaped, truncate, 3-4 lines thick. Nov.- 

 Feb. F.v.M. Eucal. 3:6 (as E, pauciflora). Maiden, 

 Grit. Rev. Eucal. 26, 27, 28 (figs. 1, 2). A high-moun- 

 tain 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: Ivs. 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: fr. 

 almost egg-shaped, nearly H m - 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.: Ivs. nar- 

 row, acute, 2-3 in. long: lid hemispherical, obtuse, 

 shorter than calyx-tube; stamens 2-3 lines long; anthers 

 opening by short divergent slits: fr. nearly globular, 

 the orifice much contracted, %-l in. across; rim 

 depressed. July-Oct. F.v.M. Eucal. 6:1. Valuable 

 for bees. 



62. diversicolor, F. v. M. (E. colldsea, F. v. M. E. 

 diversicolor var. colldsea, Hort.). KARRI. Fig. 1429. 

 Very tall symmetric tree: bark smooth, white: Ivs. 

 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: 

 fr. ovoid-truncate, about l Am. long by 4-5 lines thick;
