20. melanophldia, P. v. M. Silver-leaved Ironbark. 

 Small tree: bark persistent, deeply furrowed, blackish: 

 Ivs. glaucous or mealy white, sessile, from cordate- 

 ovate or orbicular to ovate-lanceolate, obtuse or acute: 

 peduncles :h- to 8-flowered : anthers very small and 

 globular; cells parallel and distinct: fr. truncate-globu- 

 lar, 2 or 3 lines long. 



cc. Lvs. scattered, lanceolate. 



21. siderophldia, Benth. Large-leaved Ironbark. 

 Tree, 150 ft. high : bark wholly persistent, deeply and 

 somewhat anastomosingly furrowed; furrows yellowish 

 or dark brown: lvs. elongated: lid conical, very acute, 

 about 3 lines long: outer filaments straight in bud; an- 

 thers very minute, roundish ; stigma not dilated. 

 October. F. v. M. Eucal. 4:8. — Timber very strong, hard 

 and durable; used for railroad ties, wharf piles, spokes 

 and tool-handles. 



22. drepanophylla, P. v. M. Low, stunted tree : bark 

 ribbed, dark gray: lvs. thin, often over 6 in. long; 

 veins fine, numerous, parallel and very diverging: um- 

 bels 3- to 6-flowered: lis. large; calyx-lid about as long 

 as the tube (not exceeding 2 lines long): fr. 3 to 4 

 lines in diameter; valves level with or hardly project- 

 ing beyond the rim. Said to be near £. crebra, differing 

 mainly in the large flowers and in the larger, harder 

 and more globular fruit. 



Var. leptophlSba, Luehm. (F. leptophleba, F. v. M.), 

 is said to be chiefly distinguished by the lvs. being 

 thicker and the veins more oblique. Timber strong, 

 hard and very durable ; used for bridges, mine props 

 and fence posts.

 railroad ties, piles, fence posts, and in the construction 

 of bridges and wagons; also suitable for splitting into 

 palings.

 bark of trunk persistent,

 bees. Dec.-Peb. P. v.M. Eucal. 7:8.— Timber remark- 

 ably durable ; used for ship-building, wheelwrights' 

 work, mallets, etc.: seems to thrive well in low, sour, 

 swampy ground near the seacoast.
