EUCALYPTUS 



sile; anthers with a large dorsal gland near the apex: 

 fr. large, slightly angular-streaked; valves thick, con- 

 vergent, emersed; border broad, depressed. F.v. M. 

 Eucal. 6:3.

 %in. in diameter: Ivs. lanceolate, rarely lin- 

 ear: calyx-tube and lid not ribbed.

 angular or wanting; calyx-tube conspicuously angular: 

 lid pyramidal-hemispheric: fr. angular: valves deltoid, 

 almost enclosed. August. F. v. M. Eucal. 1:3. Ascends 

 to 4,000 ft. elevation. Timber especially esteemed for 

 wheelwrights' work; also used for house-building, fence 

 rails, etc. ; excellent for fuel. 



HH. Calyx-tube and pedicels terete: fr. -valves snort, 



often deltoid. 

 1. Capsule inserted below the rim of the calyx-tube, or 



on a level with it. 

 J. Frs. urceolate (i.e., urn-shaped). 



42. Baileyana, F. v. M. Tall tree : bark persistent 

 throughout, fibrous: foliage dense and shady: Ivs. much 

 dotted : anthers broadly cordate, opening by divergent 

 slits: fr. rather large, globular-urn-shaped, 3-celled ;

 tough and durable; used for fence posts, etc. 



Jj. Frs. mostly ovate-truncate, never urceolate: pedicels 

 short; calyx-lid hemispherical, mostly blunt and 

 shorter than the tube. 

 K. Leaf-veins fine, numerous, very divergent. 



43. uncinata, Turcz. Shrub, branching from near the 

 base with several thin stems : bark deciduous, smooth 

 and grayish or reddish: Ivs. firm, very light green, nar- 

 row: fls. small; stamens remaining bent inward in an- 

 thesis ; anthers very minute, almost globular, opening

 shining, hemispherical, short-pointed: anthers almost 

 oval, opening by parallel longitudinal slits : capsule 

 somewhat sunk below the narrow rim of the calyx-tube. 

 A very hardy species. Cattle and sheep readily browse 

 on the foliage, as it lacks the peculiarly pungent Euca- 

 lyptus odor. May, June. G.C. II. 19:437; III. 2:781; 

 11:787. 



Var. undulata, (E. Gunnii, F. v. M. Eucal. 4:5.,notof 

 Hook. E. undulata, Luehm., not of F.v. M.). SWAMP 

 GUM. Tall tree: Ivs. longer (over 3 in. ), broad and 

 somewhat undulate : fr. top-shaped. Yields a great deal 

 of nectar, and flowers earlier than E. viminalis. Tim- 

 ber strong and useful. 



JJJ. Frs. ovate or globose, truncate: rim rather broad 

 and flat ; anthers broader than long almost 

 kidney -shaped, opening by divergent longitudi-

 bark persistent on trunk and lower branches, fibrous: 



EUCALYPTUS 



555 



Ivs. rather small, narrow-lanceolate, attenuate into the 

 petiole; veins not much spreading; oil-dots large and 

 not very numerous, translucent : fr. globose, trun- 

 cate or shortly ovale. F. v. M. Eucal. 5-1 BM 

 3260. B.R. 11:947 (as E. longi folia). G.C. III. 6:ie! 

 Timber not strong, but suitable for shingles, rails 

 staves, inner building material, etc. Foliage yields 

 more volatile oil than that of any other species tested. 



Var. r6gnans, F. v. M. GIANT GUM. Very tall tree, 

 (415 ft. or less high): bark usually smooth, whitish, 

 fibrous only near the base: Ivs. large, broad-lanceolate- 

 oil dots very fine, numerous. 



Var. angustifdlia, F. v. M. Graceful, spreading tree : 

 branchlets drooping : Ivs. very narrow : fls. very nu- 

 merous in the umbel. Jan.-Apl., and more or less 

 throughout the year. 



n. Capsule raised above the rim of the calyx-tube: 

 Ivs. mostly large, inequilateral; veins very di- 

 verging: stems of young plants nearly terete: an- 

 thers longer than broad, opening by parallel

788. Fruits and buds of 

 E. viminalis (X%). 



J. Flowers mostly three in an umbel. 



48. viminalis, Labill. MANNA GUM. Fig. 788. Tall 

 and graceful, spreading tree, 300 ft. or less high: bark 



persistent, roughish and 

 dark-colored ( never fibrous ) , 

 or deciduous, very smooth 

 and grayish white: seedling 

 leaves lanceolate : pedicels 

 almost none or very short: 

 lid semi-ovate, mostly short- 

 pointed. F. v. M. Eucal. 

 10:10. G.C. III. 4:597.-A 

 hardy species, withstanding 

 considerable frost and strong 

 winds. Timber not as strong 

 as that of many other spe- 

 cies, but frequently em- 

 ployed for shingles, fence rails and ordinary building 

 purposes. Sheep will feed on the foliage. A valuable 

 bee tree. Growing readily in California from voluntary 

 seedlings. Seed said to retain its vitality ten years. 



JJ. Flowers more than three in an umbel. 



49. 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 it has more than 3 flowers in an umbel, 

 by the fibrous bark and roundish seedling leaves : pedi- 

 cels almost none : calyx-lid almost hemispherical or 

 shortly and bluntly conical. March-May. F.v.M. Eucal. 

 4:9. One of the hardiest species: timber used mostly 

 for fencing and fuel. 



50. rostrata, Schlecht. RED GUM. Tree, 200 ft. or less 

 high: bark early deciduous, smooth, ashy gray or whit- 

 ish: pedicels conspicuous: calyx-lid acuminate, usually 

 ending in a beak (occasionally blunt). Apl., May. 

 F.v.M. Eucal. 4:7. Useful for bees. Prefers a moist 

 soil with a clayey subsoil ; thrives in ground periodi- 

 cally inundated for a considerable time, and even in 

 slightly saline places : stands 22 F. in Italy. Timber 

 hard, heavy, strong and extremely durable, either above 

 or under ground or in water ; suitable for fence posts, 

 piles and railroad ties; also extensively used in ship- 

 building and for wood bricks for street paving; said to 

 make a better fuel than wood of E.Globulus. Some- 

 what hardier than E.Globulus. 



51. teretic6rnis, Smith. FLOODED GUM. Tall tree: 

 bark smooth: peduncles elongated: pedicels conspicu- 

 ous: calyx-lid conical, not beaked, often much elon- 

 gated: fr. almost globose through the broad, ascending 

 rim. Apr., May. F. v. M. Eucal. 9:8. Closely related to 

 E. rostrata. Will thrive on undrained ground. Tim- 

 ber used by wheelwrights. 



52. rudis, Endl. Tree, 80 ft. high, or less : bark per- 

 sistent, rough: peduncles %-l in. long: pedicels short: 

 calyx-lid conical, not beaked ; commissural line be- 

 tween calyx tube and lid prominent : rim of fr. only 

 slightly ascending. Sep.-Nov. F. v. M. Eucal. 10:8. 

 Stands drought better than many others, and promises
