ORDER XXII. BOMBACEÆ. Kunth. 
Calyx gamosepalous, campanulate or cylindrical, truncate or quinque- 
partite, with a few minute bracteas on the outside. Petals hypogynous, 
5, regular, or none : æstivation twisted. Stamens hypogynous, 5; 10, 
15, or more: filaments cohering at the base into a tube, which is sol- 
dered to the tube of the petals, divided above into 5 parcels, each of 
which bears 1 or more anthers, intermixed sometimes with barren fila- 
ments: anthers l-celled, linear. Ovarium of 5 (rarely 10) carpels, 
either strictly cohering or partly distinct : styles as many as the carpels, 
free, or more or less cohering. Placentz in the axis. Fruit various, 
capsular, or indehiscent, usually with 5 valves and loculicide. Seeds 
often inclosed in a woolly or pulpy covering ; sometimes with a fleshy 
albumen and flat cotyledons ; sometimes exalbuminous with wrinkled 
or convolute cotyledons.— Leaves alternate, with stipules. Pubescence 
on the herbaceous parts stellate.
