ate, from a broadly conical base: fr. about 4 lines in 

 diameter; rim thick. F.v.M. Eucal. 3:7. -Timber suit- 

 able for floor boards, 

 railroad ties, telegraph 

 poles, and wood bricks 

 for street paving.

 Idris, var. acmenio'ides, Benth.). White Mahogany 

 Gum. Tall tree : bark of trunk persistent below, fibrous : 

 peduncles not much compressed, slender: lid hemi- 

 spherical, pitinted at the summit: friiit not exceeding 3 

 lines in diameter; rim thin. F.v.AI. Eucal. 10:1.— Timber 

 heavy, strong and durable; good for palings, rails, floor 

 boards, etc.

 in jYo. S2, &. Misdoni) ; tnargin entire : fruit 

 rarely exceeding % in. in diameter, trvncate- 

 ovate. 



32. Kisdoni, Hook. Drooping Gum. Small or medium 

 sized tree: bark deciduous, smooth: branches usually 

 yiendulous, )>ark brown or ashywhite: Ivs. acute, ovate: 

 lid hemispherical, obtuse: anthers kidney-shaped, open- 

 ing by divergent longitudinal slits. Closely related to 

 £J. amyydalina.

 short prdieels. 



E. Lid nutch brooder than the calijx-tHhe. 



33. gomplioc6pliala, DC. Tooart Tree. Tree, 120 ft. 

 or less high: bark persistent, rough but not stringy, 

 rather dark on old trunks, smooth and grayish on 

 younger trees and branches: Ivs. thick, narrowly acumi- 

 nate, pale green: peduncles broadly flattened; pedicels 

 wanting: lid almost hemispherical: fr. large, top-shaped ; 

 border broad, convex. Nov. P. v. M. Eucal. 7:4. — A very 

 distinct species, easily distinguishable by the broad 

 lid. Timber tough, heavy Jiiid rigid, texture close. 

 grain twisted, shrinks but little and does not split while 

 seasoning ; suitable for largn sruntlings where great 

 strength is needed, also in ship-huilding and for bridge 

 :3npport.s. One of the strongest woods known. 



EE. Lid not or only slighthj broader than the calyx-tube. 



F. Calyx-tube and lid warty; avthers larger than broad, 



opening by nearly parallel longitudinal slits. 



34. gl6bulus, Labill. Blue Guji. Figs. T81, 785, 786. 

 Tree, 300 ft. or less high: bark grayish or bluish white, 

 smooth except at the base of the trunk: Ivs. lanceolate, 

 thick: calyx-tube and lid covered with bluish white wax: 

 fr. large, angular. Dec. -Feb. F.v.M. Eucal. 0:2. G.C. II. 

 15:601; III. 2:784; 10:737. — Very attractive to bees, but 

 the nectar has a strong and unpleasant odor. In Cali- 

 fornia more extensively planted than any other Gum, 

 and readily spreading by voluntary seedlings. Will 

 stand protracted drought without irrigation in a region 

 of only 8 or 10 inches annual rainfall (Franceschi). The 

 most rapid-growing species. Timber used in Australia 

 by ship-builders for planking and keels; also for fence 

 rails, telegraph poles, railroad ties, shafts and spokes. 

 It has been recommended for wine casks. Will tolerate 

 19° F. Fig. 785 shows the stamens (5) and the structure 

 of the bud. Nos. 1-4 are K nat. size; 5 is on a larger 

 scale. No. 4 is a section of a bud. 



35. alplna, Lindl. Shrub, 12 ft. high: Ivs. inequilater- 

 ally half-ovate, blunt, acute on young shoots, leathery: 

 fls. sessile in the leaf axils, solitary or few: fr. large, 8 

 lines wide, almost hemispherical, not angular. Sept.- 

 Nov. F.v.M. Eucal. 2:1. — A very rare and interesting 

 alpine species, possibly suitable for street planting. 



FP. Calyx-tube and lid smooth or rough, but not warty: 

 Ivs. nnich exceeding 1 in. in length. 



G. Stameyis not inflexed in the bud {see also I^o. 51, E. 



tereticornis): peduncles broadly flattened: calyx 

 lid long, cylindrical, obtuse : anthers ellipsoid, 

 opening by parallel longitudinal slits. 



36. L61inianni, Preiss. Tall shrub or small tree: bark 

 coming otf in irregular sheets, roughish and reddish: 

 fls. greenish yellow; calyx lid often 1% in. long: ovary 

 convex at the top: fr. half immersed in the receptacle, 

 about M in. in diameter; valves connivent into a cone, 

 tapering into the persistent base of the style. July- 

 Sept. —Valuable ornamental tree. 



37. corntita, Laltill. Yate Tree. Large tree: calyx 

 lid 1-1/4 in. long: filaments yellow: ovary almost on a 

 level with the calyx rim, the top flat or at length slightly 

 convex; style thickened at the base: fr. free (not im- 

 mersed in the receptacle). July-Sex>t. F.v.M. Eucal. 

 9:1. — Closely related to the preceding. Used success- 

 fully as a roadside tree in southern California; adapted 

 to the lemon belt, and tolerating alkaline and saline soils 

 (Franceschi). Prefers a somewhat humid soil. Timber 

 hard, tough and elastic, suitable for shafts and frames 



of carts, and considered equal 

 to ordinary ash wood. B. M.

38. occldent&Iis. Endlich. 

 Flat-topped Yate. Fig. 787. 

 Tall tree: bark deciduous, 

 mostly smooth : Ivs. narrow- 

 lanceolate : calyx lid K-/4 in- 

 long; filaments yellowish: fruit- 

 valves only half exserted, awl- 

 shaped, free. F. v. M. Eucal. 

 fi: 5. — Individuals show great 

 diversity in time of flowering, 

 so that specimens may be found 

 in blossom at any time between August and April. 



39. pUtypua, Hook. {E. obcorddta. Turcz.). Tall 

 shrub, 'SO ft. or less high: bark smooth, grayish: Ivs.

 cles flattened and winged, bent downwards: fls. sessile, 

 dull red or yellowish white, not conspicuous : calj'S- 

 tube prominently angular, much broader than the conic- 

 cylindrical lid : fr. truncate-ovate, very angular, border 

 compressed; flowering almost continuously, but never 

 much at a time. F.v. M. Eucal. 7:6. Hook. Icon. 849. 



GG. Stamens inflexed in the bud: frui/s from S^ tolzn.
