282 XXXVI. MALVACE^. 



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

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

 ' Genera Plantarum.' 



TRIBE 1. HALVED. Staminal column antheriferous to the top. Styles as. many as ovarian 

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

 ceous, folded or contorted. 



Sub-tribe 1. MALOPE.E. Carpels oo , densely congested ; ovule 1, ascending. Malope, 

 Kitaibelia, Palava. 



Sub-tribe 2. EUMALVE.E. Carpels iu one whorl'; ovule 1, ascending. Althcea, Lavatera, 

 Malva, CalirrJioe, Sidalica, Malvastrum. 



Sub-tribe 3. SIDE.*. Carpels in one whorl ; ovule 1, pendulous. Plagianthus, Hoheria, 

 Anoda, Crlstaria, Gaya, Sida, Bastardia. 



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

 Wissadula). Hoivittia, Kydia, Wissadula, Abutilon, Sphccrrliea, Modiola. 



TRIBE II. URENE*. Staminal column truncate or toothed, anthers on its outer surface. 

 Style-branches 10. Carpels 5, separating from the axis. Cotyledons of Malveoa. Malachoa, 

 Urcna, Pavonia, Goethea, Malvariscw. 



TRIBE III. HIBISCE.E. Staminal column of Ureneao. Styles as many as the ovarian cells. 

 Carpels locnlicidal, persistent. Cotyledons of Malveoj. Kostelclykya, Desaschista, Hibiscus, 

 Lagunaria, Furjosia, Tlte^esia, Gossypium, &c. 



TRIBE IV. BOMBACE*. 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. ADANSONIE<E. Leaves digitate. Bracteoles distinct or 0. Cotyledons 

 crumpled or convolute. Adansonia, Pachira, Boinbax, Eriodendron, Chorisia. 



Sub-tribe 2. MATISCIE.*. Leaves simple, 3-5-nerved. Bracteoles distinct or 0. Petals 

 5. Cotyledons twisted or convolute. Hampia, Cavanillesia, Matisia, Ochrorua. 



Sub-tribe 3. FREMONTIE^;. Leaves of Matiscieee. 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 Sterculiacece.) 



Sub-tribe 4. DURIOXE.E. Leaves simple, penninerved, quite entire, lepidote beneath. 

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

 Neesia, &c. ED.] 



Malvacca are closely allied to StercKliacea: and Tiliacetf (see these families). They are so near 

 JBombacea that Eentham and Hooker fil. liave united them ; having separated them from bterculiacea on 

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

 are united in pairs; whereas SiercHlincea, whose anthers are apparently one-celled, are so through the 

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

 branches, each bearing 2-oe anthers, sometimes free and reniform (Adausonia), sometimes adnate, globose 

 (Ctelostegia), or linear (Matma), or sinuous (Ochroma) the capsule is loculicidal or indehiscent; the 

 cotyledons are coiled (Ochroma), or folded and contorted (Adansonia, Bomba.r, &c.),or flat (Cheirostemon). 

 have also some vegetative characters in common with Urticea.
