EUCALYPTUS 



EUCALYPTUS 



BB. Fls. in simple, axillary umbels: fr. with S or more 



cells, and not- exceeding 1 in, in length. (See 



also E. paniculata, No. 7.) 

 c. Lid projecting beyond the rim of the calyx tube : 



anthers distinctly longer than broad, opening by 



almost parallel longitudinal slits. 

 8. corynocalyx, F. v. M. SUGAR GUM. Tree, 120 ft. 

 high : bark smooth: Ivs. elongate-lanceolate, slightly 

 curved, somewhat paler beneath : lid almost hemispheri- 

 cal : fr. urn-shaped-ellipsoid, longitudinally streaked. 

 June-Sept. F. v. M. Eucal. 2:2. The best drought-re- 

 sisting tree for desert regions (Mueller); the foliage 

 contains but little oil, is sweetish; and is browsed by 

 stock. Needs protection from sea breeze when planted 

 along the coast. An ornamental tree used for roadside 

 planting in southern California. Timber hard, strong, 

 durable; useful for railroad ties and fence posts. Said 

 to be the quickest-growing shade tree for regions ex- 

 posed to hot, bleak winds; will stand 18 F. 



A

cc. Lid not projecting beyond the rim of the calyx-tube. 



D. Lvs. opposite : anthers minute, not longer than 



broad (nearly oval), opening by longitudinal slits. 



9. doratdxylon, F. v. M. SPEAR-WOOD. A pretty, 

 small tree or tall shrub : bark smooth, greenish white : 

 Ivs. stalked, narrow, lanceolate : umbels bent downward, 

 on recurved, slender, compressed peduncles : lid termi- 

 nating in a beak-like point: outer filaments sterile. 

 F.v.M. Eucal. 4:4. Graceful tree, of slender habit: 

 timber firm and elastic.

 Handsome tree : branches spreading ; branchlets slen- 

 der and more or less drooping: bark smooth, whitish 

 gray: Ivs. broad, elongated, thick: lid hemispherical, 

 twice or thrice shorter than the tube, usually quite 

 blunt: anthers almost kidney-shaped, opening by very 

 divergent, longitudinal slits : fr. shortly-pedicelled. 

 Nov.-Feb. F. v. M. Eucal. 3:6. An alpine tree, and one 

 of the hardiest species. Cattle browse on the foliage 

 in seasons of drought. Timber used for fuel, fences 

 and building purposes; sometimes badly affected with 

 scale. 



EE. Leaf-veins all more or less diverging from the 



midrib. 



F. Foliage much paler beneath (see also No. 25, E 

 marginata): anthers almost heart-shaped, opening 

 by longitudinal slits. 



11. diversfcolor, F. v. M. (E. coUssea, F. v. M. E. di- 

 versicolor, var. colossea, Hort.). KARRI. Very tall, 

 symmetrical tree, attaining 12 ft. in diameter : bark 

 smooth, white: Ivs. scarcely inequilateral, dark green 

 and shining above; veins feathery-spreading, fine : lid 

 nearly hemispherical : fls. white, in heavy clusters ; 

 stamens all fertile. March-May, and again in Novem. 



F.v.M. Eucal. 5:4. A rapid grower, profuse bloomer, 

 and considered a good tree for bees. Timber elastic, 

 valued for building purposes, shafts, masts and fence 

 rails. 



FF. Foliage of equal color on both sides, or nearly so. 

 G. Pedicels elongated : lid conical. 



12. longifolia. Link. WOOLLYBUTT. Tall tree: bark 

 persistent, gray, rough or wrinkled, somewhat fibrous : 

 Ivs. elongated ; veins very spreading : lid broadly conical, 

 acute, pale : stamens all fertile ; anthers cuiieate- or 

 oblong-oval, opening by longitudinal slits : stigma not 

 dilated: fr. rather large, bell-shaped, semiovate, angu- 

 lar: margin outwardly ascending. F. v. M. Eucal. 2:4. 

 Flowering almost continuously. Valuable for bees. 



13. leucbxylon, F. v. M. WHITE IRONBARK. Tall tree, 

 usually branching below : bark mostly deciduous, 

 smooth, pale : Ivs. narrow-lanceolate, grayish or dull 

 green: fls. usually in 3's, white or rarely pink: lid semi- 

 ovate, pointed: outer stamens sterile; anthers truncated, 

 opening by apical pores ; stigma much dilated : fr. 

 slightly contracted at the orifice, rarely slightly angu- 

 lar. Jan.-Apr. F. v. M. Eucal. 1:4. Valuable bee tree, 

 making an excellent honey. Timber superior to that of 

 almost any other Eucal ypt for certain purposes. Val- 

 ued for hardness and durability; used by wagon- and 

 ship-builders, also for railroad ties and underground 

 work, for axe handles and for turning. Will grow on 

 stony ridges not adapted to ordinary cultural purposes. 



14. sideroxylon, Cunn. (E. leucdxylon, var. siderdxy- 

 lon, Authors). RED IRONBARK. Perhaps not specifically 

 distinct from E. leucoxylon: usually not branched be- 

 low: bark persistent, rough, dark red: Ivs. green: fls. 

 white or yellowish. 



Var. rdsea, Hort. (E. leucdxylon, var. rdsea, Hort.). 

 Lvs. green: fls. rose-colored. March, Apr. A handsome 

 form and profuse bloomer. 



Var. pallens, Auct. (E. leucdxylon, var. pdllens, 

 Benth. E. Ietic6xylon, var. pdllida, Hort. E. siderdxy- 

 lon, var. pdllida, Hort.). Lvs. silvery gray: fls. red. 

 A profuse bloomer. 



GG. Pedicels short or none : fertile seeds not winged. 



H. Fr. much contracted at the orifice, nearly globular : 

 outer anthers kidney -shaped, opening by divergent 

 slits. 



15. buprestium, F. v. M. Shrub, 10 ft. high : Ivs. 

 about 2 in. long, narrow; oil-dots much concealed: fls. 

 small, almost pear-shaped in bud : lid hemispherical, 

 pointed : inner anthers opening by large, roundish 

 pores : fr. nearly 1 in. in diam., truncate-globular, 

 grayish ; margin compressed. July, Aug. F. v, M. Eucal. 

 6:1. Valuable for bees. 



16. piperita, Smith. PEPPERMINT STRINGY-BARK. 

 Tall tree : bark persistent, gray, rough and fibrous : oil- 

 dots copious, transparent: lid broad-conical, acute: fr. 

 about % in. in diam. F. v. M. Eucal. 3:8. 



HH. Fr. but slightly or not at all contracted. 

 i. Diameter of fr. nearly 1 inch. 



17. Planchoniana, F. v. M. Tree, 100 ft. high: pedun- 

 cles erect, broadly compressed : pedicels very short or 

 almost none : lid narrow-conical, from a semi-ovate 

 base, about as long as the calyx-tube, both longitu- 

 dinally streaked : anthers ovate or roundish ovate, 

 opening by longitudinal slits. July. F. v. M. Eucal. 4:6. 

 A profuse bloomer. Timber heavy, hard and durable;

 BARK. Tall tree: bark persistent, grayish, very fibrous, 

 but rather soft and fragile : Ivs. very inequilateral at 

 base : peduncles nearly terete, mostly slender : calyx 

 tube terete : lid hemispherical, depressed or scarcely 

 pointed. March-May. F.v.M. Eucal. 3:5. Much val- 

 ued in Australia for bees. Will grow on poor, dry soil, 

 but subject to frost in California. Wood useful only for
