Descriptive Characters of 



rarely ovate, acute, short-mucronate, gradually tapering Into 

 the petiole, penninerved, veined, with slightly recurved 

 margin, above smooth, beneath with branchlets and rachis 

 grey-silky ; racemes pedunculate, axillary and terminal, 

 elongate, sometimes divided, drooping, their development 

 centripetal; calyces three times longer than the pedicel; 

 outside rutilous, silky ; inside, betow the middle, white- 

 bearded; style long-exserted, glabrous or scantily hairy at 

 the extremity ; germen-stalked, glabrous ; stigma sublateral, 

 ovate, slightly umbonate ; follicle ellipsoidal, thinly ribbed, 

 glabrous* 



Along the waters of the Buffalo Range, on the summits of 

 Mount BuUer and Mount Tambo, on the sources of the 

 Mitta Mitta, at Mount Hotham and Mount Latrobe. 



A truly majestic plant, when, by descending into the 

 vallies, it assumes a height of twelve feet and more. In higher 

 altitudes it becomes a dwarfer bush, with shorter, almost 

 ovate leaves. 



26. Orites lancifoKa, 



(Sect. Acroderris.) 



Leaves oblong-lanceolate, flat, glabrous, blunt, net-veined, 

 perfectly entire ; spikes axillary and terminal, sub-soUtary ; 

 calyx smooth; germen silky-downy, follicle silky. 



On the rocky summits of the the Australian Alps (5-6,000 

 feet high), for instance on Mount Wellington, MountHotham, 

 Mount Latrobe, in the Munyang Mountains, in the upper 

 valleys of the Mitta Mitta, &c. 



This fine shrub is besides Grevillea Victoria the only real 

 alpine species of this natural order indigenous to the Austra- 

 lian continent. But I am uncertain whether it may prove ^ to 

 be identical with 0. Milligani, of which hitherto no description 

 has been given. 



Ctpekoideae. 



27. Scirpus polystachyus. 



Stems tall, trigonous, foliate, glabrous ; leaves flat, on the 

 keel and margins scabrous; cyme terminal, many times com- 

 pound, little shorter than the three or five bracts of the invo- 

 lucre ; spikelets ovate-oblong, partially soHtary stalked, par-
