J. H. MAIDEN. 



watered South West, but, in the later settled arid goldfiekte 

 area, the name is given more or less loosely to several 

 (perhaps many) species, as it is a common character of 

 trees of that region to have somewhat smooth trunks, with 

 more or less dark flaky bark on the butt, and these are 

 called " Blackbutts." 



The Dundas specimens may be described as follows : 

 Juvenile leaves not available. 



Mature leaves. — Only eleven leaves were received. They 

 are pedunculate, narrow-lanceolate, acuminate, usually 

 with a hooked tip, shiny, equally green on both sides, 

 moderately rich in oil, venation scarcely visible, margin 

 thickened, midrib the only obvious vein, lateral veins 

 roughly parallel and acutely attached to the midrib. 

 Petioles 1 — 1*5 cm., length of leaves 8-9 cm., breadth 

 under 1 cm. 



Flowers. — Buds not fully developed are alone available. 

 Brownish-black in colour, sessile or with a very short 

 pedicel, the common petiole slightly flattened and about 

 1 cm. long. The calyx-tube about '5 cm. long, slender, and 

 tapering very gradually; the operculum pointed, conical* 

 and about half the length of the calyx-tube. The anthers 

 are immature but they open in parallel slits and have a 

 large gland at the back near the top. 



Fruits. — Three fruits are available, picked off the ground 

 and somewhat weather-worn. Oylindroid, slightly con- 

 stricted in the middle, with some indistinct ribs, in very 

 low relief below the constriction. '7 cm. long, and about 

 '4 cm. broad at the orifice. Tips of the valves not appear- 

 ing above the orifice. 



Habitat. — The village of Dundas, Western Australia* 

 after which the species is named, is situated fifteen miles 

 south of Norseman, on the Esperance road, and was the
