EUCALYPTUS 



trading. Dec.-May. F.v.M. Eucal. 6:2. G.C. II. 

 15:601; 111.2:777,784; 10:737. Gn. 71, p. 18; 75, p. 

 606. Maiden, Crit. Rev. Eucal. 79 (figs. 1-12). The 

 best species for general planting: extensively used in 

 Calif. Its combination of rapidity of growth, straight- 

 ness of trunk, great strength of wood, and its known 

 ability to flourish under a wide range of conditions in 

 Calif., give it a great advantage over any other species 

 (Ingham). Wood stronger than that of E. rostrata and 

 E. tereticornis, yellowish white, easily stained, not dur- 

 able in the soil in Calif. : used there for insulator pins, 

 spokes, felloes, whiffle-trees, handles, flooring and inte- 

 rior finish; a good species for fuel: logs check badly in 

 curing, this much less in the so-called "San Jos6 blue- 

 gum" or "re-enforced gum" which, however, is thought 

 by some to be only a selection of the best trees of ordi- 

 nary blue-gum. Lvs. distilled for oil: fls. yield much 

 honey to bees, but because of its pro- 

 nounced flavor there is little or no j^j^\ 

 demand for it in retail trade (Richter). 1 ^^^^. 

 Endures minimum temperatures of 25 

 and high temperatures of the San Joa- 

 quin and Sacramento Valleys but not 

 of the desert districts: resists consider- 

 able drought when once established 

 but best development is attained only 

 on good and fairly deep soil. Fig. 1427 

 shows the stamens and the structure 

 of the bud. Nos. 1-4 are half natural 

 size; 5 is on a larger scale. No. 4 is a 

 section of a bud. 



Var. compficta, Hort. DWARF BLUE 

 GUM. Densely branched from the 

 ground, forming a symmetrical rounded 

 compact tree : lower foliage as in young 

 growth of E. globulus but smaller with 

 the longer narrower Ivs. only near the 

 top. Said to have originated near 

 Niles, Calif., from seed of the ordinary 

 blue-gum (Calif. Nursery Co.). 



The specific name globulus is some- 

 times written with a capital G, because 

 it is a noun rather than an adjective; 

 but the initial letter is here written in 

 lower case in accordance with a recom- 

 mendation of the International Botan- 

 ical Congress. 



19. alpina, Lindl. Shrub, 12 ft. high: 



Ivs. inequilaterally semi-ovate, blunt, acute on young 

 shoots, 2-^4 in. long, thick and leathery: fls. sessile in 

 the If .-axils, solitary or few: fr. hemispherical, %-l in. 

 wide, not angular; rim broad; valves protruding. 

 Sept.-Nov. F.v.M. Eucal. 2:1. 



20. tetraptera, Turcz. Shrub or small tree: branches 

 often sharply angled: Ivs. very thick, oblong-lanceo- 

 late: fls. solitary, on flat recurved peduncles; lid 

 4-angled, much shorter than calyx; stamens not over 

 J^in. long: fr. prominently 4-angled, 2-3 in. long, %-l 

 in. wide, the valves well inclosed. F.v.M. Eucal. 2:10. 

 Highly ornamental; once grown at Santa Monica, 

 according to Kinney who says that the calyx-tube and 

 stalk just before the lid falls become a brilliant crim- 

 son and are by far the most striking part of the fl. 



21. cosmophylla, F.v.M. Tall shrub or small tree: 

 bark smooth, ash-colored: Ivs. broad-lanceolate, 3-5 

 in. long, very thick and rigid: peduncles almost 0; 

 lid hard, low-hemispheric, blunt or short-pointed; 

 stamens 4-6 lines long; anthers ovate, opening by dis- 

 tinct parallel slits: fr. globose-truncate, not contracted 

 at orifice, smooth, 7-8 lines across; rirn thick. F.v.M. 

 Eucal. 7:2. 



22. cordata, Labill. Small tree, to 50 ft. : Ivs. oppo- 

 site, sessile, orbicular to ovate, somewhat crenate, 

 rarely over 3 in. long, usually white-mealy, as also 

 the infl. : calyx broadly campanulate, obtuse at base, 



1427. Eucalyptus 

 globulus. No. 18. 



smooth; lid low-hemispherical, obtuse or with sharp 

 tip, shorter than tube; stamens 3-4 lines long; anthers 

 opening by parallel slits: fr. globular-truncate, hard, 

 4-6 lines thick; valves rarely protruding. F.v.M. Eucal 

 8:1. B.M. 7835. G.C. III. 3:803; 30:456; 47:168. 

 Useful mainly as an ornamental. 



23. pulverulenta, Sims. Lvs. always entire: calyx- 

 tube turbinate, tapering to the base; lid variable, 

 mostly conical: otherwise about as in E. cordata. F.v.M. 

 Eucal. 8:7. B.M. 2087. Gn. 75, p. 140. The very 

 blue foliage supplies a pleasing contrast for ornamental 

 planting. 



24. cornftta, Labill. YATE TREE. Moderate-sized 

 or large tree, usually low-branched and spreading: 

 bark either deciduous in irregular sheets or persistent 

 and rough : Ivs. oblong or broad-lanceolate, often obtuse, 

 2-5 in. long: fls. greenish yellow, numerous, in dense 

 heads; lid cylindric, horn-like, 1-1 ^ in. long; stamens 

 13 / 2~2 in. long: fr. short-cylindric, 4-5 lines wide; 

 valves much exserted and connivent into a beak-like 

 projection. June-Oct. F.v.M. Eucal. 9:1. B.M. 6140 

 (lid too highly colored). Used successfully as a road- 

 side tree in S. Calif.: especially good as a shade tree: 

 adapted to the lemon belt, and tolerating alkaline and 

 saline soils (Franceschi) . Timber hard, heavy, tough, 

 and elastic. 



25. Lehmannii, Preiss (E. cornuta var. symphio- 

 cdrpa, Auct. E. macrocera, Turcz.). Perhaps only a 

 form of E. cornuta: Ivs. more often short and obtuse: 

 fr. half immersed in the receptacle, forming a solid 

 woody mass. June-Oct. 



26. platypus, Hook. (E. obcorddta, Turcz.). Tall 

 shrub or small tree: bark smooth, grayish: Ivs. petioled, 

 oval to obcordate, very obtuse, 1-2 }/% in. long, leathery 

 and shining: peduncles winged, recurved; fls. dull red 

 or yellowish white, not conspicuous; lid conic-cylindric, 

 much narrower than the prominently angled calyx- 

 tube; stamens J^-%in. long: fr. truncate-ovate, very 

 angular, 4-7 lines thick. F.v.M. Eucal. 7:6. Hook. 

 Icon. 849. 



27. occidentals, Endl. FLAT-TOPPED YATE. Spread- 

 ing shrub or medium-sized tree: bark deciduous, 

 smooth, or somewhat persistent and rough: Ivs. 

 lanceolate, acuminate, 1^2-5 in. long: lid cylindric- 

 conic, }^-%in. long; stamens yellowish or orange, 

 K-%in. long: fr. bell-shaped, with spreading rim, 5 

 lines wide; valves 'exserted, sharp. Oct.-May. F.v.M. 

 Eucal. 6:5. Suited to the coast districts; subject to 

 frost. 



28. coccifera, Hook. Small glaucous tree with 

 smooth white bark: Ivs. lanceolate, thick and shining, 

 often tipped by a slender curved mucro: fls. nearly 

 sessile, in close terminal clusters; calyx prominently 

 angled; lid very short and flat, rugose; stamens about 

 3 lines long, all perfect; anthers reniform, opening by 

 divergent slits: fr. obovoid-truncate, 4-6 lines across. 

 B.M. 4637. G.C. II. 12:113; 13:395; 111.2:787, 789; 

 3:799, 801; 9:169. Gn. 71 p. 591. Maiden, Crit. Rev. 

 Eucal. 28 (figs. 3-5). A high-mountain form com- 

 pared by some to E. amygdalina but recognized by 

 the depressed lid and longer calyx. Of value as an 

 ornamental: a very hardy species suitable for the foot- 

 hill districts. 



29. virgata, Sieb. Shrub or small tree with stringy 

 bark: Ivs. lanceolate, thick and shining: calyx not 

 angled; lid conical, granular-roughened, as also the 

 tube; stamens scarcely 2 lines long; anthers reniform, 

 opening by pores which extend into oblong slits: fr. 

 globose-truncate, smooth, 3-6 lines across. Maiden, 

 Crit. Rev. Eucal. 43 (figs. 1, 2). 



Var. stricta, Maiden (E. stricta, Sieb.). Lvs. linear or 

 linear-lanceolate: lid often shortly pointed. Maiden, 

 Crit. Rev. Eucal. 43 (figs. 12-17). F.v.M. Eucal. 10:9. 

 B.M. 7074.
