AUSTRALIAN PLANTS. 9 



shaped, three-lobed. Capsule sessile, depressed, with three valves and 

 three cells ; valves bearing the septum in the middle ^ cells two-seeded, 

 including at the top a slight quantity of woolly hair. Axis of the cap- 

 sule persistent, thread-like. Seeds obovate, three-sided. 



This new Malvaceous genus, which bears, in acknowledgment of his 

 devotiou to botany, Dr. Godfrey Howitt's name, is nearest related to 

 LaguYKjeay less to Fugosia, 



21. Hovvittia trilocularis, F. Muell. 



Hab. On bushy declivities around Lake King. 



A flexile shrub, attaining the height of twenty feet ; leaves ovate or 

 oblong-lanceolate, with a heart-shaped base, above scabrous, beneath 

 tomentose ; stipules never distinctly developed ; peduncles axillary, 

 solitary, filiform, single-flowered ; petals obovate, purplish. 



22. Sida intricatay F. Muell. ^ fruticulose, upright or diffuse, much 

 branched ; leaves small, ovate-roundish, truncate at the top, toothed, 

 but entire at the cuueate base, above scantily, beneath densely covered 

 with grey stellate hairs ; petioles much shorter than the leaves, often 

 suq3assing in length the subulate setaceous stipules ; peduncles axil- 

 lary, solitary, drooping, shorter than the leaves ; segments of the calyx 

 subdeltoid] carpels five, a little depressed, on the back almost even 

 and puberulous, at the commissura netted ; seeds brown» puberulous. 



IIab, In sandy, loamy plains between Mount Hope and the Murray, 



also towards the Darling River. 



This bears some affinity to Sida corrugata, but its growth is upright 

 and intricate ; it is much more robust, the flowers, leaves, and capsules 

 are much smaller, the latter not rough. 



23. Sida humiUima^ F. Muell.; suffruticose, procumbent; leaves 

 thin, ovate-oblong, obtuse, cordate or rounded at the base, unequally 

 and deeply crenate, above scantily, beneath densely covered with a 

 stellate, somewhat shining indument ; petioles hardly the length of the 

 leaves, but longer than the subulate-linear stipules ; peduncles axillary, 

 solitaiy or two or three together, filiform, articulated near the middle, 

 nearly equal to the length of the petiole ; segments of the calyx sub- 

 deltoid, acute; carpels eight to ten, depressed, rough, at the commis- 

 sure asperous;. seeds brown, smooth. 



Hab, In dry plains on the Avoca and Murray. In South Australia, 



on St. Vincent's Gulf, and the Kapunda. 



Not dissimilar to Sida corrugala.
