126 XXII. MALVACEJE. [Abiuilon. 



with a concave centre, 7 to 8 lines diameter, densely villous ; carpels about 20, 

 closely packed, rounded or very obtuse at the top and separating completely 

 without leaving the persistent placentas of A. /]raveolens. — Sida mutica, Delil.; 

 DC. Prod. i. 470. 



Hab.: Keppel Bay, Percy Island, sources of the Burdekin and oh the' Dawson, and Eock- 

 hampton. , , 



The specimens are not complete, but agree well with those frofa tropical Africa, where the 

 species is common and generally referred to A. asiaticiim, but is not Sida asiatica of Linnteus. 

 S. tomentosa, Eoxb., appears to be an E. Indian form of the same species, with the tomentum 

 mixed with spreading hairs as in A, graveolens, from which it cannot ajways be distinguished 

 without good fruit. It is this form which is represented as Sida graveolens, Bot. Mag. t. 4134.

12. A. Cunninghamii (after Allan Cunningham), Benth. Fl. Aiistr. i. 205. 

 Allied to A. Fraseri, but apparently shrubby, much branched and densely clothed 

 with soft, short, but velvety tomentum, without spreading hairs. , Leaves cordate- 

 orbicular, very obtuse, crenate, 1 to 2in. diameter, thick and soft. Flowers on 

 rather long peduncles in the upper axis. Calyx 4 to 5 lines long, uensely tomen- 

 tose, deeply divided into broad acuminate lobes. Petals about |^in. long. Carpels 

 10 or fewer, distinct and seceding completely from the axis, rounded at- the top, 

 densely but closely tomentose, and not scarious. 



Hab.: Estuary of the Burdekin. 



18. A. Fraseri (after C. Fraser), Hook. ; Walp. Ann: ii. 158; Jiefith. Fl. 

 Austr. i. 205. A low branching undershrub, rarely exceeding 1ft., shortly 

 tomentose or pubescent, with longer hairs occasionally intermixed. Leaves cor- 

 date, from orbicular to ovate, crenate, often all under lin. diameter, but some- 

 times Ifin. Pedicels rarely exceeding the petioles. Flowers rather large. Calyx 

 3 to 4 lines long, tomentose-pubescent and sometimes hirsute^ di^ded ,to about 

 the middle. Petals more than twice as long. Fruit usually exceeding the calyx, 

 slightly tomentose or pubescent, 3 to 4 lines diameter, depressed iii the centre ; 

 carpels 6 to 10, very disinct, and seceding completely from the axis, obtuse or 

 almost pointed at the top, not scarious. Seeds 1 or 2 in each carpel, glabrous or 

 minutely pubescent. — Siria Franeri, Hook, in Mitch. Trop. Austr. 368, 



Hab.: On the Maranoa, Sutton River and Broadspund, Comet Eiver. 



Vax. halophilnm. Leaves usually orbicular, very obtuse, often truncate or retuse, the carpels 

 5 or 6 lines long and very broad and obtuse. — A. halophiVuin, F. v. M. in Linnsea, xxv. 381.-^ 

 N. S. Wales, S. Australia, and on Queensland border. 



-7. MODIOLA, Moench. 



, (Carpels resembling the nave of a vpheel.) 



Calyx 5-cleft, with 8 bract'eoles at the base. Carpels numerous, arranged 

 circularly, 2-valved, spuriously 2-celled transversely by the inflexion of a vajlve- 

 like process, 2-seeded. Badicle in the upper seed superior, in the lower seed 

 inferior. — Prostrate and usually creeping herbs. Leaves divide^. Peduncles 

 axillary, 1 -flowered. — A. Gray. 



1. IME. multifida (leaf much divided), Mcench. Stems diffuse, more or less 

 hirsute, often rooting at the joints. Leaves 1 to 2in. diameter, palmately 3 to 5- 

 lobed ; segments incised and toothed. Pedicels longer than the petioles. 

 Bracteoles linear-lanceolate. Segments of the calyx ovate-lanceolate. Petals 

 obovate, purplish-red, a little longer than the calyx. Stamens 15 to 18. Carpels 

 15 to 20, lunate, much compressed, hispid on the back, wrinkled on the sides 

 towards the base. A rigid process rising from the back on the insides of the 

 carpel extends to the axis, separating the upper from the lower seeds. — Malva 

 CaroUniana, Linn. 



Hab.: This American plant has become naturalised near many southern townships.
