Finally tall ; leaves scattered, from oval- to narrow-lanceolar, slightly or distinctly curved, 

 somewhat paler and not shining underneath ; their lateral veins subtle, numerous, pennately 

 spreading, the circumferential vein at a slight distance from the edge of the leaf ; oil-dots copious, 

 transparent or more or less concealed ; umbels axillary and solitary, on conspicuous slender 

 sometimes compressed stalks, with 3-12 flowers ; tube of the calyx semiovate or somewhat top- 

 shaped, gradually attenuated into a rather short or moderately elongated stalklet, not angular, 

 hardly half as long as the conical or rarely hemiellipsoid lid ; stamens all fertile, not bent back 

 while in bud ; anthers cordate-kidneyshaped, opening by longitudinal slits ; style elongated ; 

 stigma not expanded ; fruits ovate-globular, truncated, the margin of the summit rather narrow, 

 but finally flat ; valves three, short, enclosed or but slightly exserted ; seeds all very angular and 

 without any appendage, the sterile mostly not narrow, but smaller than the rather large fertile 

 seeds. 



From King George's Sound to Cape Leeuwin and to the Moore-River, forming the principal 

 forests in South- Western Australia and occupying a region not far removed from the coast. 



This tree, the famous " Jarrah " of South-Western Australia, there passing also as Mahogany- 

 tree, rises exceptionally to a height of about 150 feet, good-sized trees averaging 100 feet. Stems 

 have been measured 80 feet to the first branch and exceptionally 35 feet in circumference at 5 feet 

 from the ground, and even instances are on record of the stem having attained a girth of CO feet 

 at 6 feet from the ground through the formation of buttresses. The bark is persistent and some- 

 what fibrous, wherefore the East-Australian term of Stringybark-tree might be applied to this 

 species also. Branchlets rather slender, angular. Leaves on conspicuous more or less compressed 

 stalks, sometimes of a more papery, sometimes of a more leathery thickness, variable in length 

 and also in comparative width, occasionally only about 2 inches long and more ovate, often 

 terminating in a narrow acumen. A few of the umbels in exceptional cases forming a small 

 terminal panicle. Stalklets usually of about the same length as the calyx-tube, but sometimes 

 twice as long. Lid occasionally thrice as long as the calyx-tube, long-pointed and somewhat 

 curved. Stamens attaining a length of 5 lines, but in a small-flowered variety only half as long ; 

 filaments finely capillary, cream-colored, rarely yellow ; anthers pale, their slits divergent and at 

 the summit confluent ; gland of the connective extremely minute. Style thin, as long as the 

 stamens. Ripe fruit from hardly inch to fully inch long, neither shining, nor dark-colored. 

 Valves broader than long, inserted not far below the orifice. Seeds forming two rows in each cell, 

 the fertile grains 1 to 2 lines long, black, somewhat shining, much fewer than the sterile seeds, 

 which are pale-brownish and 1 to 1 lines long and nearly as broad. 



This tree received several specific names ; the difficulty of recognizing it commenced soon 

 after James Donn (in his hortus Cantabrigiensis, sec. edit. p. 101 in 1800) had established the 

 name, but perhaps not for this species ; because Sir James Smith, when in 1801 giving a very
