Plants Collected in Capricornic Western Australia. 57 



Andropogon Australis, Sprengel. Along with the normal 

 form a variety, remarkable for its quite pale vestiture. 



Andropogon Gryllus, Linrie. 



Antljistiria ciliata, Linne, fil. 



Anthistiria membranacea, Lindley. 



Erianthus fulvus, Kunth. 



Cheilanthes tenuifolia, Swartz. 



Cheilanthes vellea, F. v. M. 



Mr. King's collection contains also another Stemodia, 

 which was not known from Australia before, and seems also 

 unrecorded from Southern Asia or elsewhere. I have 

 designated it specifically with the finder's name, but in 

 absence of fruit the plant cannot be described satisfactorily, 

 nor be placed sectionally into the genus, though it would likely 

 merge into Limnophila. The plant is glabrous ; the leaves 

 are opposite and remain well green in drying; the upper, 

 (which alone became available,) are linear or narrow-lanceolar 

 and not distinctly denticulated ; the flowers are nearly 

 sessile, solitary in the axils ; the bracteoles narrow-lanceolar, 

 much shorter than the calj^x; the three outer segments of 

 the latter are J — f-inch long, of herbaceous texture, almost 

 lanceolar, the two inner very considerably narrower, but 

 nearly as long; the corolla is glabrous, except inside near 

 the base, and a little hairiness occurs also on the upper 

 lobes; the tube is broadly cylindrical, almost as long as the 

 labia; the upper lip is bifid, thus producing orbicular- 

 cuneate lobes; the lower lip is bluntly 3-dentated ; the 

 filaments are conspersed with stipitate minute glands; the 

 anthers have their cells parallel but almost disconnected, and 

 are fixed from a dorsal small protuberance to the filament ; 

 the style is glabrous ; the stigma divided into two semi- 

 orbicular lobes; the ovary ovate-conical, glabrous and 

 pointed.
