 heads, sessile or pedicellate, usually pentamerous and all liermaphro- 

 dite. Calyx campanulate or funnel-sliaped, distinctly toothed. Corolla 

 funnel- shaped, petals firmly united below the middle. Stamens inde- 

 finite, monadelphous at the base, filaments several times the length of 

 the corolla ; anthers minute, not gland-crested. Ovary sessile or shortly- 

 stalked; style filiform, stigma capitate minute. Pod large, thin, flat, 

 strap-shaped, straight, indehiscent or subindehiscent, continuous within,
