EUCALYPTUS 



EUCALYPTUS 



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. 



63. salmonophlSia, F. y. M. Finally tall: Ivs. nar- 

 rowly lanceolate, 2-5 in. long, shining; oil-dots 

 copious: lid broadly conical, slightly longer than the 

 tube; anthers roundish, opening by parallel slits: fr. 

 semi-ovate, narrowed at base, 2 lines thick; valves 

 much exserted, long-pointed. F.v.M. Eucal. 9:6. 



64. rostrata, Schlecht. RED GUM, Fig. 1430. Tree, 

 to 200 ft.: bark of mature trunks dark gray, either 

 smooth and deciduous or somewhat persistent near the 

 base and then checking into thick scales or even fur- 

 rowed; bark of seedlings and twigs reddish: Ivs. nar- 

 rowly lanceolate, acuminate, 4-6 in. or more long: 

 calyx-tube hemispheric; lid usually hemispheric and 

 provided with a narrowed point or beak, sometimes 

 merely conical and not beaked, rarely over 3 lines long; 

 stamens 2-4 lines long; anthers oblong, opening by 

 parallel slits: fr. nearly globular, rarely above 3 lines 

 thick; rim broad, prominent; valves entirely pro- 

 truding, even before they open. April-July. F.v.M. 

 Eucal. 4:7. One of the most valuable species; next 

 to the sugar gum and forest gray-gum perhaps the most 

 drought-resistant; withstands frosts better than blue- 

 gum; endures the intense heat of Imperial Valley, on 

 the Colorado Desert; grows where the ground is inun- 

 dated for a considerable time; makes a good growth in 

 alkali soils, yet best results are secured only on good 

 soil, especially if moist and with a clayey subsoil. A 

 slow-growing species in regard to height, but one of the 

 first in regard to diam. -growth (Ingham). Timber

very durable, both above and below ground: heavy, 

 takes a good polish: light red to deep red in color: not 

 so strong as sugar and blue -gums and trees more 

 irregular in growth: suitable for railroad-ties, piles, 

 fence-posts, and the like: difficult to work when dry, 

 therefore scarcely suitable for furniture. Blossoms 

 supply honey to bees. 



65. tereticornis, Smith. FOREST GRAY GUM. 

 FLOODED GUM. Bark and the general characters as in 

 E. rostrala: Ivs. rather broadly lanceolate: calyx-tube 



turbinate; lid slenderly conical, acuminate, rarely 

 abruptly beaked, 3-6 lines long, always much longer 

 than the tube; stamens 3-6 lines long: fr. obovoid or 

 nearly globular, 3-4 lines thick; rim very broad and 

 prominent; valves protruding. April-July. F.v.M. 

 Eucal. 9:8. Closely related to E. rostrata; usually 

 coarser, the Ivs. broader, peduncles and pedicels 

 stouter, and fr. larger; yet variable in all these charac- 

 ters. According to Ingham, this species has an erect 

 habit of growth, while E. rostrata grows very crookedly. 

 Withstands fully as wide a range in temperature, 

 moisture, and soil conditions as does E. rostrata: timber 

 similar but usually paler in color; more valuable because 

 of its more regular growth. E. amplifolia, Naudin, 

 known in Calif, as the "Cooper" or "round-leaf tereti- 

 cornis," is a form with large roundish Ivs. when young. 



66. macrorhyncha, F. v. M. Tall tree: bark dark 

 gray, furrowed and fibrous: Ivs. lanceolate, acuminate, 

 3-5 in. long; lower ones broader, thick, and coriaceous; 

 veins very oblique, prominent: calyx-tube turbinate, 

 the edge forming a prominent ring with the conical 

 lid; anthers reniform, opening by divergent slits: fr. 

 depressed-globose, 4-6 lines thick; rim broad, convex.

 (figs. 3-21). 



67. Gunnii, Hook. f. CIDER GUM. Small, often 

 scrubby tree: Ivs. thick, shining, less than 3 in. long: 

 lid shining, hemispherical, short-pointed; stamens 2-3 

 lines long; anthers nearly oval, opening by parallel 

 slits: fr. pear-shaped, truncate, 3-4 lines across; rim 

 thin; valves sometimes slightly protruding. April- 

 July. B.M. 7808. G.C. II. 19:437; III. 2:781; 11:787. 

 A very hardy species: cattle readily browse on the 

 foliage, as it lacks the peculiarly pungent eucalyptus 

 odor. Fls. only 3 in the typical form, but this appa- 

 rently not cult, in Amer. 



Var. acervula, Deane & Maiden. Buds and foliage 

 often of a yellowish cast: fls. usually 4-8 in the 

 umbel: fr. M-^in. across. F.v.M. Eucal. 4:5 (main 

 fig.). The form commonly grown in Calif. Sapwood 

 yellowish. 



Var. undulata, Auct. (E. undulata, Luehm., not of 

 F. v. M.). SWAMP GUM. Tall tree: Ivs. longer (over 3 

 in.), often 2 in. broad, somewhat undulate or plane: fr. 

 top-shaped. Yields much nectar: flowers earlier than 

 E. viminalis. Timber strong and useful. 



Var. montana, Auct. A mountain form of E. Gun- 

 nii, the only species which withstands the climate of 

 the east of England. 



68. mellioddra, Cunn. HONEY-SCENTED GUM. YEL- 

 LOW Box. Spreading tree with somewhat drooping 

 habit, to 150 ft. high: bark somewhat persistent below, 

 roughish, brownish gray without, yellowish within, 

 flaking off above, leaving the branches smooth: Ivs. 

 narrow, acuminate, 3-5 in. long: fls. small, the calyx 

 about 2 lines across; lid conic-hemispherical; stamens 

 2-3 lines long; outer ones sterile; anthers minute, 

 truncate, opening by terminal pores or short slits: fr. 

 distinctly stalked, truncate-globular, under 3 lines thick. 

 Feb.-Aug. F.v.M. Eucal. 2:5. Maiden, Grit. Rev. 

 Eucal. 61 (figs. 1-14). Will grow on poor hillside soil 

 but best growth is made in the valleys. Timber used 

 in Austral, by wheelwrights and shipbuilders: makes 

 excellent fuel: fls. particularly rich in nectar and much 

 sought by bees. 



69. odorata, Behr. (E,. cajupiitea, Miq.). Differs 

 from E. melliodom chiefly in the more erect habit and fr. 

 which is often nearly sessile, obconic, not or scarcely 

 contracted at orifice. F.v.M. Eucal. 2:7. Maiden, 

 Grit. Rev. Eucal. 51 (figs. 9-19). Grown at Fresno, 

 Calif. : may be of value for its oil. 



70. dorat6xylon, F. v. M. SPEAR- WOOD. Beautiful 

 shrub or small tree: bark smooth, greenish white: Ivs. 

 all opposite or nearly so', narrowly lanceolate, acumi-
