[Bombax malabaricum is diplostemonous; the five sepal-stamens repeatedly branch, and the filaments bear unilocular anthers; the five petal-stamens bear bilocular anthers.]
B. Schizocarps, with 1-seeded fruitlets, most frequently nut-like and reniform (Figs. [449], [451]).
3. Malveæ, Mallow Group. The carpels are arranged in one whorl (Fig. [449]); the number of stylar-branches equals that of the carpels; fruitlets 1-seeded, reniform, indehiscent, but detaching themselves from one another and from the persistent central column (Figs. [450], [451]).—Malva has an epicalyx of 3 free leaves. A flower with 2 suppressed bracteoles is situated in the axil of the foliage-leaves; one of these supports a homodromous foliage-shoot which forms a repetition of the main axis, the other an antidromous flower which continues the branching as a unipared scorpioid cyme.—Althæa, Rose Mallow, has an epicalyx of 6–9 leaves united at the base.—Lavatera, Sida, Anoda, Bastardia, etc., have no epicalyx.
