DESCRIPTION. 



XXL E. marginata Sm. 



See Part VIII, p. 241 (1907). 



The following additional statement was published by me in Journ. W.A. Nat. Hist. 

 Soc, vol. iii, January, 1911 :— 



These notes are based on field observations made by me in Western Australia from September to 

 December, 1909, but I have taken the opportunity of incorporating a few notes from other sources. 



Mr. William Dunn, a native of Albany, over 60 years of age, says that Mahogany is the name 

 given by the old settlers to the timber later on known as Jarrah ; that he does not remember the name 

 Jarrah ever having been employed until the introduction of saw-milling machinery ; he has sawn timber 

 from boyhood. 



In- bark, and somewhat in general appearance, the Jarrah resembles the E. resinifera of coastal 

 New South Wales and Queensland. It flowers as a shrub. 



Following is a description of the juvenile leaves. They were received from Mr. Mas Koch, and 

 have not been previously described : — 



Lanceolate, sharply acuminate, slightly oblique, rounded at the base, petiolate ; thin in texture, 

 pale on the underside, glabrous on both sides ; margin thickened and slightly recurved, the intra-marginal 

 vein distinctly removed from the edge ; midrib distinct, lateral veins fairly distinct, pinnate, at an approxi- 

 mate angle of 45 degrees with the midrib, smaller veins anastomosing and obvious ; oil-dots not obvious. 



The irregularly striate appearance sometimes seen in fruits of this species and in a few others, e.g., 

 E. diversicolor, is the result of the contraction of subsucculent vascular tissue over longitudinal bands of 

 fibro -vascular tissue. 



E. marginata is termed " Mahogany " or " Jarrail " (can it be a misprint or an 

 early spelling of Jarrah ?) (" Discoveries in Australia," J. Lort Stokes, ii, 132, 1835). 



VARIETY. 



E. marginata Sm., var. Staerii, Maiden in Journ. Roy. Soc. N.S.W., xlvii, 230 

 (1913). 



King River road, near Albany, Western Australia (J. Staer, August, 1911). 



The fruits of the normal species, as figured by Mueller in the " Eucalyptographia " 

 are depicted as 1-5-2 cm. long and 1-7 cm. broad, and tapering somewhat into a thickened 

 pedicel. I have received from Mr. J. Staer, specimens oi'E. marginata with fruits in
