168 THE VICTORIAN NATURALIST. 



Lodicules narrow. Grain loose, narrow }i inch long. 



Flowering October, November. — Sandy desert, Lowan shire. 

 1895, F. Reader. 



The late Baron v. Mueller provisionally named this species 

 Stipa Readeri, pending an examination and close comparison 

 with some West Australian species. 



In aspect it is quite different from any other species and the 

 tallest of all of them. 



The section of the genus Stipa, with the flowering glumes 

 silky-hairy and the elongated and non-ciliated ligule, to which 

 this species belongs, comprise the West Australian S. compressa, 

 S. Drummondii, S. pycnostachya and the well-known S. setacea, 

 the latter occurring in all the colonies. 



From these S. acrociliata may be readily discerned by its 

 height, its broad and flat, long, lower leaves, and the character- 

 istic peculiarities of its glumes.

DESCRIPTIONS OF NEW AUSTRALIAN PLANTS IN 



THE NATIONAL HERBARIUM, MELBOURNE. 



By J. G. Luehmann, F.L.S., Curator. 

 (Bead before Field Naturalists' Club of Victoria, 8th March, 1897.) 

 Eucalyptus corrugata, Luehmann. 



A tree attaining about 30 ft. in height, with a smooth ashy-grey 

 bark. Leaves on rather long petioles, mostly narrow-lanceolar, 

 slightly falcate, narrowed at the base, acuminate, 3 in. to 4 in. 

 long, yi in. to rarely 2 /i in. broad, rather thick, dark green and 

 very shining on both sides, black-dotted, the lateral veins rather 

 numerous and spreading, but hardly visible without a lens, the 

 marginal vein close to the edge. Peduncles axillary or lateral, 

 nearly terete, about half an inch long, bearing an umbel of 3 to 5 

 shortly pedicellate flowers. Calyx-tube hemispherical, with 6 to 

 8 very prominent ridges, about ^ in. across, brownish, shining. 

 Operculum hemispherical, with ridges similar to those of the 

 calyx. Stamens mostly inflected in bud ; anthers oblong, opening 

 by parallel longitudinal slits. Fruit hemispherical, not much 

 larger than the flowering calyx, mostly 4-celled, nearly flat-topped, 

 the valves shortly protruding. 



Golden Valley, in the interior of Western Australia, W. A. 

 Sayer. 



This species is evidently allied to E. incrassata, but none of 

 the forms of that species have such high ridges nor the same 

 hemispheric shape of the calyx and corolla. E. pachyphylla, 

 which has also prominent ribs, can be easily distinguished by the 

 broader dull-coloured leaves, as well as other characters.
