1. calophylla, R. Br. Medium-sized umbrageous 

 tree, with dense foliage: bark dark, corky, deeply fur- 

 rowed: Ivs. ovate-lanceolate, firm and thick; veins 

 nearly parallel and very spreading: fls. large, white or 

 cream-color, rarely pink, in large clusters; lid thin, 

 nearly flat: fr. 1-1% in. wide, ovate-urnshaped, very 

 thick and woody; seeds large, black, the edges acute 

 but scarcely winged. July-Oct. B.M. 4036 (as E. 

 splachnicarpa). F. v. M. Eucal. 10:2. G.C. III. 

 20:661. Ornamental tree of rather slow growth, not 

 enduring frost or dry atmosphere. Good shade tree 

 for avenues in the coast districts. The fall bloom is 

 valuable for bees. Bark rich in kino. The wood is 

 tough, useful for wheelwrights' work and for building, 

 but not durable underground. The frs. of this and the 

 next have been polished and used for pipe-bowls. 



2. ficifdlia, F. v. M. CRIMSON-FLOWERED EUCAL YPT. 

 Fig. 1424. Handsome small tree, rarely to 50 ft. : bark 



dark, furrowed : Ivs. 

 ovate- lanceolate, 

 firm and thick; 

 veins almost trans- 

 verse: fls. red, large 

 and in large clus- 

 ters; lid thin, nearly 

 flat: fr. 1-1% in. 

 wide, broadly urn- 

 shaped, the walls 

 very woody; border com- 

 pressed; seeds pale brown or 

 almost red, winged on one end 

 or also along one side. Aug., 

 Sept. F.v.M. Eucal. 7:3. B. 

 M. 7697. G.C. III. 42:376, 

 377. Gn. 71, p. 441. R.H. 

 1904:568. Very ornamental, 

 especially in bloom. Tender 

 and adapted only to the lemon 

 belt; a heat-resisting avenue 

 tree, withstanding drought. 

 The fls. vary from pink to crim- 

 son and scarlet and the forms 

 do not come true to seed; 

 grafted plants are now offered 

 in the trade, the bright scarlet 

 shade being generally pre- 

 ferred. 



3. corymbdsa, Smith. BLOOD- 

 WOOD. Small tree: outer bark 

 persistent, gray and turning 

 somewhat black; inner yellow- 

 ish or reddish brown; of upper 

 branches smooth and often 

 reddish: Ivs. lanceolate, some- 



,1 hi E " calyptus what leathery; lateral veins 

 globulus. showing spray 



of mature foliage vei T numerous, fine, parallel 

 ( X K) and two leaves of and nearly transverse: fls. y el- 

 sucker foliage. No. 18. lowish white, fragrant, in large 



corymbs, the peduncles and pedicels long; lid de- 

 pressed-hemispherical, short-pointed; stamens becom- 

 ing 5 or 6 lines long: fr. somewhat urn-shaped, about 

 %in. wide. Aug.-Dec. F.v.M. Eucal. 5:2. Tree suit- 

 able only for the coast districts. Wood brown or red, 

 durable, and serviceable underground or in water, but 

 rendered inferior by the many gum veins. (Ingham.) 



4. eximia, Schau. MOUNTAIN BLOODWOOD. Large 

 tree: bark scaly, brownish or yellowish, smooth only 

 on the younger branches: Ivs. falcate-lanceolate, thick; 

 lateral veins parallel and widely spreading but scarcely 

 visible: fls. sessile, in small heads of a panicle, the 

 peduncles angular or flattened; lid nearly hemispherical, 

 pointed; stamens 3-4 lines long: fr. urn-shaped, with 

 thin rim, about %in. wide through the middle. Oct.- 

 June. F.v.M. Eucal. 9:2. A stately species with 

 abundant showy bloom. Wood soft; useful only for fuel. 



5. maculata, Hook. SPOTTED GUM. Handsome tree, 

 to 150 ft., the foliage mostly near the summit: bark 

 smooth, whitish or reddish gray, deciduous in patches, 

 thus exposing lighter areas and giving the trunk a 

 spotted appearance: Ivs. lanceolate; veins parallel, 

 rather oblique to the midrib: lid hemispheric, double; 

 fls. short-stalked; stamens 4-5 lines long: fr. globular- 

 urnshaped, thin-rimmed, scarcely %in. thick. May- 

 July. F.v.M. Eucal. 3:4. Hook. Icon. 619. Maiden, 

 For. Fl. N.S.W. 7:27. Timber valuable for ship- 

 builders and used especially in coach factories and 

 for handles; wood hard, light-colored, close-grained: 

 growth fairly rapid. 



Var. citrioddra, Bailey (E. citriodora, Hook.). 

 LEMON-SCENTED GUM. Like the species but foliage 

 strongly lemon-scented. A favorite ornamental tree 

 in the warmer parts of Calif.: subject to frost: young 

 plants useful for window or cool greenhouse cult. The 

 oil is clear white and of a pleasing, penetrating odor, 

 used especially as a perfume for soap. 



6. polyanthemos, Schau. RED Box. AUSTRALIAN 

 BEECH. Well-branched often irregular and picturesque 

 tree, 40-150 ft.: bark brown or gray, persistent, rough 

 on old trees: Ivs. orbicular to ovate, mostly 2-4 in. 

 long by 1%~3 in. wide, rarely oval-lanceolate and 

 scarcely 1 in, wide, dull and grayish green on both 

 sides: fls. small, white, stalked, in close panicles; sta- 

 mens 1 or 2 lines long, the outer ones sterile : fr. goblet- 

 shaped, not contracted at orifice, 2-3 lines across, the 

 valves not exserted. Jan.-April. F.v.M. Eucal. 3:9. 

 Maiden, Grit. Rev. Eucal. 58, 59 (figs. 1-3). Useful 

 for ornamental planting, because of its spreading habit, 

 characteristic silvery foliage, and profuse bloom; also 

 for windbreaks, for fuel, and for bees: timber exceed- 

 ingly hard and durable, but sts. become hollow in age 

 in Austral. A drought- and heat-resistant species: 

 endures minimum temperatures of 15-20: of only 

 fairly rapid growth. 



7. populifdlia, Hook. POPLAR Box. Compact 

 straight-growing tree: bark rough to the branchlets: 

 Ivs. ovate or roundish, rarely lanceolate, 4 in. or less 

 long, very lustrous and intensely green on both sides: 

 fls. small, white, on very short stalks, the umbels 

 paniculate; stamens 1-2 lines long, all fertile: fr. very 

 small, semi-ovate, the valves inclosed. Hook. Icon. 

 879. Maiden, Crit. Rev. Eucal. 58 (figs. 11-18). 

 Probably as useful and adapted to as wide a variety of 

 conditions as the closely related E. polyanthemos. 



8. melanophldia, F. v. M. SILVER-LEAVED IRON- 

 BARK. Small tree : bark persistent, dark, furrowed : Ivs. 

 sessile, orbicular to ovate-lanceolate, glaucous or 

 white-mealy: fls. small, in terminal or axillary corymbs : 

 fr. truncate-globular, 2-3 lines across; rim thin; valves 

 included or slightly exserted. 



9. siderophloia, Benth. BROAD-LEAVED IRONBARK. 

 Tall tree: bark wholly persistent on old trunks, rough 

 and deeply furrowed; furrows yellowish or dark brown;
