CLASSIFICATION. 



tube. Stamens usually many, often mono- or poly-adelphous, 

 more rarely diplostemonous, or with one whorl suppressed or 

 reduced to staminodes. Ovary of 2-many carpels with 

 axile placentation, but ovary often showing a tendency to 

 become apocarpous in fruit (each carpel then becoming a 

 coccus, drupel, or follicle .^ 



Exceptions : — 



Stellate hairs few or absent in some Corehorus, Bombax and very- 

 few Hibiscus. Petals in Sterculia. Carpel only 1 in Waltheria. 



19. The Hibiscus Family. 



Trees, shrubs or herbs with regular flowers. Calyx 

 usually persistent and gamosepalous. Epicalyx usually 

 present. St. many united into a tube, or (Tribe Bombacese) 

 more or less free and pentadelphous. Anthers ultimately 1- 

 celled, cell often sinuous. Ovary of 5 (rarely 3) -many 

 carpels, separating into cocci when ripe leaving a persistent 

 columella, or fruit capsular. 19. Malvaceae (p 179). 



20. The Jute Family. 



Trees, shrubs or undershrubs rarely herbs with regular 

 flowers. Calyx deciduous with free sepals. Epicalyx absent. 

 St. many not united into a tube, more rarely 10 or 5. 

 Anthers 2-locular. 20, Tiliace® (p. 192). 



21. The Sterculia or Udal Family. 



Trees, shrubs and undershrubs with reg. or zygomorphous 

 often polygamous flowers with persistent calyx gamosopalous, 

 with or without epicalyx. Stamens usually ten (obdiploste- 

 monous), with the alternate whorl often reduced to stami- 

 nodes, sometimes numerous, rarely 5, monadelphous or united 

 into a tube below. Anthers 2-locular (young 4-locular) and 

 extrorse. Ovary usually 5-locular. Fruit usually capsular, 

 but carpels follicular in Sterculia.
