repute for durability. The whole plant has a somewhat 

 strong peppermint-like odour. 



Juvenile leaves. — Only the first two or three pairs 

 opposite, at first softly tomentose with stellate hairs, 

 eventually becoming markedly hispid on both surfaces; 

 sessile to shortly petiolate, ovate, acute, paler on the lower 

 surface, the margins undulate; secondary veins fine, loop- 

 ing and forming a moderately distant intramarginal vein; 

 4 — 7 cm. long, 2 — 4 cm. broad. 



Intermediate leaves alternate, smooth, from paler 

 beneath to dark green on both surfaces, narrow lanceolate 

 to broadly, and obliquely lanceolate, the apex mucronate 

 to shortly acuminate, 5-8 cm. long, 2-4 cm. broad. 



Mature leaves lanceolate, falcate, attenuate, somewhat 

 oblique, occasionally oblong lanceolate, from 10—15 cm. 

 long, and 2 to 3J cm. broad; petiolate, thickish, equally 

 green on both sides, but particularly in the upper part of 

 the tree, having a steel-grey or "silver-leaf" cast, hence 

 the vernacular name. Venation spreading, the secondary 

 veins making an angle of about 30° with the midrib, the 

 intramarginal vein not close to the edge. 



Flowers.— Buds narrow, rounded, or only very slightly 

 angled, stellately arranged, pinkish or brownish at the base 

 when fresh, up to 14 in the head, sessile or nearly so, on an 

 elongated flattened peduncle. Operculum pointed, more 

 than half the length of the calyx-tube. 



Fruits small, under 8 mm. in greatest diameter, com- 

 pressed spheroid, with a comparatively small orifice, the 

 rim shining, reddish-brown, the valves well sunk, or some- 

 times very slightly exsert; up to 9 in a dense head.
