Australian Plants. 



13 



segments of the calyx subdeltoid/ acute ; carpels eiglit-ten, 

 depressed, rough, smooth, at the commissura asperous ; seeds 

 brown, smooth. 



In dry plains on the Avoca and Murray. 



In South Australia, on St. Vincent Gulf and the Kapunda. 



Not dissimilar to Sida corrugata. 



20. Abidilon Behriamm. 



Stem herbaceous, upright, hardly branched, as well as the 

 leaves covered with a velvetlike toment ; leaves cordate, 

 acuminate, repand or slightly crenate, about as long as the 

 petiol j stipules linear-subulate deciduous ; peduncles axillary, 

 solitary, one-flowered or terminal with several flowers, above 

 the middle articulated, often shorter than the petiol; segments 

 of the calyx ovat-lanceolate, acute ; carpels 9-12, tomentose- 

 pubescent,' compressed, oblique-ovate, aristate, with 2-4 black 

 somewhat scabrous seeds. 



In lagoons which become dry, and on the margins of lakes 

 on the Murray, Loddon, Darling, and Murrumbidgee. 



21. Abutilon otocarpum. 



Fruticose, upright, all over grey-velutinous ; leaves cordate- 

 orbiculate, blunt, inequally crenate, of nearly equal length 

 with the petiol; stipules hnear-subulate, deciduous; peduncles 

 axillary, solitary, one-flowered, towards the top articulate, 

 but little surpassing the length of the petioles ; segments of 

 the calyx inflated, cymbiform, long acuminate; carpels 

 numerous, shorter than the calyx, very compressed, earshaped, 

 nearly membranaceous, velutino-pubescent, with one to three 

 black glabrous rough seeds. 



Very rare on Sandhills on the Murray towards the junction 

 of the Darling. 



This Abutilon stands in some relation to Ab. halophilum 

 (Ferd. Mueller in Linnsea xxv., p. 381) from Spencer's Gulf. 



SCLERANTHE^. 



23. Mniarum singuliflorum, 



(Scleranthus mniaroides Ferd. Mueller collect.) 



Stems caespitose, somewhat flaccid; leaves upright or little 

 patent, as well as the branches smooth, Isevigate ; peduncles 

 one-flowered, at the top bibracteate; calyx turgid, 5-cleft.^ 



On bare rocks at the summit of the Cobboras mountains, 

 6000 feet above the level of the sea. Easily to be distin- 

 guished by the above notes from Mniarum biflorum (M.
