282 XXXVI. MALVACE^. 



[As the above enumeration omits Bombacew, I have given the following descrip- 

 tion of the tribes and genera of this extensive family, which is that adopted in the 

 ' Genera Plantarum.' 



Teibe 1. Malvej!. — Staminal column antheriferous to tbe top. Styles as many as ovarian 

 cells. Carpels separating from the axis (except Bastardia and Eointtia). Cotyledons folia- 

 ceous, folded or contorted. 



Sub-tribe 1. Malopej!. — Carpels oo , densely congested ; ovule 1, ascending. Malope, 

 Kitaihelia, Palava. 



Sub-tribe 2. EuMALVEiB. — Carpels in one -whorl ; ovule 1, ascending. AUlicea, Lavatera, 

 Malva, GalirrJioe, Sidalica, Malvastrum. 



Sub-tribe 3. Side^;. — Carpels in one whorl ; ovule 1, pendulous. Plagianihus, Hoheria, 

 Anoda, Crist aria, Gay a, Sida, Bastardia. 



Sub-tribe 4. ABUTiLEa;. — Carpels in one whorl ; ovules 2-oo (except one species of 

 Wissadula). Hoivittia, Kydia, Wissadula, Alutilon, Spliairrhea, Modiola. 



Tribe II. Ueene^. — Staminal column truncate or toothed, anthers on its outer surface. 

 Style-branches 10. Carpels 5, separating from the axis. Cotyledons of Malvese. Malaalioa, 

 Urena, Pavonia, Ooetliea, Malvaviscus. 



Teibe III. IIibisce.5:. — Staminal column of Ureneae. Styles as many as the ovarian cells. 

 Carpels loculicidal, persistent. Cotyledons of Malvese. Kosielclyhya, BesascJiista, Hibiscus, 

 Lagunaria, Fugosia, Thespesia, Qossypium, &c. 



Teibe IV. BoMBACEiE. — Staminal column 5-8-cleft at the top, or rarely to the base, 

 rarely entire. Anthers free, reniform, or cells adnate, globose, linear, oblong, or contorted. 

 Style entire or with as many branches as ovarian cells. Capsule loculicidal or indehiscent, 

 carpels usually persistent. Cotyledons variable. — Trees. 



Sub-tribe 1. AoANSONiEiE. — Leaves digitate. Bracteoles distinct or 0. Cotyledons 

 crumpled or convolute. Adansonia, Pacliira, Bomiax, Eriodendron, Ghorisia. 



Sub-tribo 2. Matiscie^. — Leaves simple, 3-6-nerved. Bracteoles distinct or 0. Petals 

 6. Cotyledons twisted or convolute. Hampia, Gavanillesia, Matisia, Ochroma. 



Sub-tribe 3. Eeemontiej!. — Leaves of Matisciere. Petals 0. Anthers 5 2-celled, or 10 

 1-celled, adnate in pairs to ihe branches of the staminal column. Cotyledons flat. (Probably 

 a tribe of 8terculiacecB.} 



Sub-tribe 4. Dueione^. — Leaves simple, penninerved, quite entire, lepidote beneath. 

 Flowers involucellate. Fruit muricate. Cotyledons various. Gullenia, Durio, Boschia, 

 Neesia, &c. — Ed.] 



Malvacece are closely allied to Steradiacea: and Tiliacece (see these families). They are so near 

 Bombacea that Bentham and Hooker fil. have united them ; having separated them from Stm-cuUacere on 

 account of their one-celled antheis, which are only apparently two-celled in certain genera in which they 

 are united in pairs; whereas StercuUacecs, whose anthers are apparently one-celled, are so throuo'h the 

 confluence of the cells. In Bomhacea the staminal column is more or less deeply divided into 5-8 

 branches, each hearing 2-co anthers, sometimes free and reniform {Adansonia), sometimes adnate, globose 

 {Caehstegia), or linear {Matisia), or sinuous {Ochroma); the capsule is loculicidal or indehiscent; the 

 cotyledons are coiled {Ochroma), or folded and contorted {Adansonia, Bombax, &c.), or flat {Cheirostemon). 

 Malvacece have also some vegetative characters in common with TJrticecB.
