the cool season, best under a cloudy sky, and the seed- 

 lings ought 'not to get dried up in any way during the 

 process of removal, regular daily watering for some 

 time afterwards being requisite. Eucalyptus seedlings 

 for shipment to places only a few days' distance may be 

 simply packed in closed cases without much soil ; for 

 transmittal to longer distances, they must be well es- 

 tablished in pots or bamboo pieces. In this respect 

 Eucalypts should be treated like most pines and other 

 coniferous trees, and, like them, cannot be transplanted 

 when they have attained any size, even when provided 

 with a good ball of earth. But their distribution by 

 means of seeds is the easiest method, on account of the 

 durability and small size of the latter. ( F. v. Mueller: 

 adapted).

A. Fruit-valves quite enclosed in the capsule (see also 



No. 25, E. marginata: fruit must be quite mature 

 in order to determine this point). 



B. Fls. mostly in terminal or lateral panicles, not 



simple umbels (occasionally the inflorescence will 

 appear to be paniculate in section BB also, ow- 

 ing to the falling off of the leaves, so that it is 

 necessary to look for the leaf-scars in placing 

 doubtful specimens'): Ivs. scattered, petiolate (ex- 

 cept sometimes in seedlings and robust shoots). 



C. Lvs. of equal color on both sides (see also No. 4 and 



No. 7, E. corymbosa and E. paniculata). 



D. Fruit at least % in. in diameter, more or less 



urceolate: fls. and fruits pedicellate. 



1. maculata, Hook. SPOTTED GUM. Handsome tree, 

 150 ft. high : bark smooth, whitish or reddish gray, mot- 

 tled with bluish white or brown reddish spots : Ivs. lan- 

 ceolate; veins feathery-spreading: anthers opening by 

 parallel longitudinal slits ; lid double. F.v.M. Eucal. 

 3 :4. Hook. Icon. 619.. Timber valuable for ship-builders, 

 wheelwrights and coopers, and for blocks for street 

 paving. 



Var. citrioddra, Bailey (E. citriodora, Hook. ). LEMON- 

 SCENTED GUM. Handsome tree : trunk slender : bark 

 smooth, white: branchlets long, slender and drooping: 

 Ivs. very long and narrow, light green, strongly lemon- 

 scented: fls. creamy white. May-July. A favorite orna- 

 mental tree, of rapid growth in the warmer parts of Cali- 

 fornia: subject to frost. Timber valuable for piles and 

 girders : volatile oil used in perfumery: the young 

 plants useful for window or cool greenhouse culture. 



DD. Fruit rarely exceeding % in. in diameter. 



2. polyanthemos, Schau. RED Box -TREE. Well 



branched tree, from 40 ft. or less to 150 ft. high: bark 

 brown or ash-gray, persistent, roughish: Ivs. from 

 orbicular to ovate, dull and grayish green on both 

 sides: lid depressed- or pyramidal-hemispherical and 

 faintly pointed: fls. small, white, in close panicles, de- 

 scribed as resembling gigantic heads of mignonette; 

 outer stamens sterile; fertile anthers truncated, open- 

 ing by terminal pores. F.v.M. Eucal. 3:9. Hook. Icon. 

 879. Fairly rapid grower. Timber extremely hard and 

 durable, unsurpassed for fuel, 1 and much used in Aus- 



tralia for ties and wheelwrights' work. Very useful for 

 bees, flowering in Jan. and Feb. 



3. hemiphloia, F. v. M. AUSTRALIAN BOX-TREE. Tree, 

 90 ft. or less high: bark of trunk persistent, solid, gray- 

 ish and somewhat wrinkled; of branches deciduous, in 

 flakes or long strips : Ivs. from lanceolate-falcate to 

 ovate-lanceolate, thick and rigid, often ashy gray; 

 lateral veins diverging at a very acute angle : lid 

 conical : anthers very minute, globular, opening by 

 lateral, pore-like apertures. F.v.M. Eucal. 5:5. 

 Timber hard and tough, valued in Australia for rail- 

 road ties, telegraph poles, shafts, spokes, etc.; also 

 makes excellent fuel. 



Var. albens, Moore (E. aliens, Miq.). WHITE BOX- 

 TREE. Bark dull green, persistent: Ivs. glaucous or 

 mealy white: fls. chalk-white. 



cc. Lvs. paler beneath than above: branchlets glabrous. 



D. Fruit urceolate (urn-shaped) over % in. long: lid 

 of calyx not broader than the tube, tearing off 

 along an irregular suture : anthers distinctly 

 longer than broad, opening by almost parallel 

 longitudinal slits. 



E. Size of fruit under 1 in. in diameter. 



4. corymbdsa, Smith. BLOODWOOD. Small tree: outer 

 bark persistent, rough-furrowed, gray and turning some- 

 what black; inner yellowish or reddish brown; that of 

 the upper branches smooth and often reddish: Ivs. lan- 

 ceolate, only slightly curved, firm; midrib very promi- 

 nent, lateral veins very numerous, fine, almost trans- 

 versely spreading; oil-dots inconspicuous: peduncles 

 and pedicels long, slender: fls. yellowish white, fra- 

 grant: lid depressed-hemispherical, short-pointed: fr. 

 large, oval-urn-shaped. Aug.-Decem. F.v.M. Eucal. 5:2. 

 Timber very hard when dry, durable under ground, 

 and much used in Australia for fence posts, rails, rail- 

 road ties, and rough building purposes: bark yields 

 about 28 per cent tannic acid; dried Ivs. about 18 per 

 cent. 



EE. Size of fruit exceeding 1 in. in diameter: Ivs. turn- 

 ing the stir face more than the edge, to the zenith; 

 veins feathery -spreading. 



5. calophylla, R. Br. Medium-sized, umbrageous tree: 

 bark persistent, dark, deeply furrowed : Ivs. broad- or 

 lanceolate-ovate, firm and thick, conspicuously stalked: 

 fls. large, white, rarely pink, in large clusters: lid thin, 

 patellar : fr. large, smooth, ovate-urn-shaped, border 

 compressed; seeds very large, black, not winged. July- 

 Oct. B.M. 4036 (as E. splachnicarpa). F.v.M. Eucal. 

 10:2. G.C. III. 20:661. Ornamental tree, but of rather 

 slow growth and subject to frost. Fruits polished and 

 sold for pipe bowls : good shade-tree for avenues : valu- 

 able for bees, flowering late into the
