vided with small petals, sqnamiform, rarely lanceolate (but in this 

 case flat not cucullate), generally little visible. Calyx generally 

 coloured, sometimes accrescent. Stamens fertile, oppositipetalous, 

 generally the same in number as the petals. Anthers two-celled 

 introrse or cxtrorse, dehiscing by clefts or pores. Staminodes 

 alternipetalous, wanting or little developed. Carpels independent, 

 or united into an ovary or into a plurilocular fruit. Seeds often 

 arillate. — (7 genera.) 



VIII. Malvece. — Flowers naked or with epicalyx, petalous. 

 Petals united only at their base among themselves, and with the 

 base of a monadelphous androceum. Tube of androceum covered out- 

 wardly in its upper part as far as the apex with one-celled extrorse 

 anthers. Carpels 1- cc 5 united in a single verticel, most generally 

 separated from the central columella at maturity. Ovules 1-co . 

 Albumen nil or little abundant. Embryo with foliaceous cotyledons 

 '2 plicate, or crumpled, contortuplicate. — (16 genera.) 



IX. MalopEjE. — Flowers hermaphrodite. Perianth and andro- 

 ceum like Malvece. Carpels go , independent, arranged without 

 apparent order at maturity upon the common receptacle. Ovaries 

 one-celled, with single ascending ovule. Free achenes. — (3 genera.) 



X. Urene^e. — Flowers hermaphrodite. Perianth of Malvece. 

 Column of the androceum supporting above and without, an indefi- 

 nite number of stamens with one-celled anthers, truncate and quinque- 

 dentate at the summit. Carpels 5, separating from the receptacle at 

 maturity. Styles double in number to the carpels (5 opposite the 

 petals and 5 alternate). Seed and embryo of Malvece. — (5 genera.) 



XL Hibisce^e.^ — Flowers hermaphrodite. Perianth of Malvece. 

 Column of androceum truncate or 5-dentate at summit very rarely 

 covered with anthers inserted on its exterior surface. Style with 

 branches equal in number to the ovary cells. Fruit plurilocular, not 

 separating from the receptacle at maturity. Seed and embryo of 

 Malvece, or with thick or much contortuplicate cotyledons. — 

 (8 genera.) 



XII. Bombace/E. — Flowers hermaphrodite, petalous. Calyx gamo- 

 sepalous, irregularly dehiscing, torn, iobed or truncate, or more 

 rarely with five deep clefts, and imbricated. Stamens often mona- 

 delphous to a variable distance, then separating into 5-10 bundles, 

 themselves ramified and each supporting one or 2-=o anthers, one-
