K. L( nf-i-ihis fiiir. numerous, very divergent. 



43. uncin^ta, Turi'z, Slirub, 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 

 by terminal pores: fr. very small. F. v. M. Eucal. 4:10. 

 —A very hardy species. 



KK. Leaf-veins not numerous, very oblique. 



44. cocclfera, Hook. Small, glaucous tree : Ivs. thick 

 and shining, under 3 in. long : peduncles short, thick 

 and much flattened upwards: calyx-tube narrow-tur- 

 binate, tapering at the base, prominently angled : lid 

 short, broad, flat or depressed, rugose: anthers kidney- 

 shaped, opening by divergent, longitudinal slits : fr. 

 almost flat on the top. Tasmania, 3,000Hl,000 ft. eleva- 

 tion. B.M. 4C37. G.C. IL 12:113; 13:395; 111.2:787, 

 789; 3:799,801; 9: 169. -Perhaps only a sub-alpine form 

 of E. amygdalina. 



45. Gunnii, Hook. Cider Gum. Small, often scrubby 

 tree: Ivs. thie.k, shining, less than 3 in. long: calyx-lid 

 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; HI. 2:781; 

 11:787. 



Var. undulita, (E. Chinnii, P. v.M. Eucal. 4:5.,notof 

 Hook. E. unduldta, huehm., not of F.v. M.). Swamp 

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

 somewhat undulate : fr. top-shaped.— Yields agreatdeal 

 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- 

 nal slits: Ivs. green: bark of trunk smooth 



46. haemastdma, Smith. White Glti. Tree : Ivs. 

 broad; veins spreading, prominent: outer stamens ster- 

 ile : fr. short, ovate-truncate, with a reddish apex. 

 P. v.M. Eucal. 2:3.— Will grow on poor, sandy land. 

 Timber of inferior quality. 



47. amygdalina, Labill. Peppermfnt Gum. Tall tree: 

 bark persistent on trunk and lower branches, fibrous: 



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. P. v. M. Eucal. 5:1. B.M. 

 3260. B.R. 11:947 (as E. longifolia). G.C. III. 6:16. 

 — 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. rfignans, P. v. M. Giant Gum. Very tall tree, 

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

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

 oil dots very fine, numerous. 



Var. angnstifdlia, P. v. M. Graceful, spreading tree : 

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

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

 throughout the year. 



II. 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 

 longitudinal slits. 



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. P. 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.

49. Stuartitaa, P. 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. rostrita, Schlecht. Bed 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. teretic6niis, 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. P. v. M. Eucal. 9:8. — Closely related to 

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

 ber used by wheelwrights. 



52. rildis, 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
