Family 277. Goodeniaceae. Mostly Australian herbs and 

 shrubs, with alternate (or opposite) leaves; flowers usually ir- 

 regular; stamens 5, free from the style. Goodenia, Scacvola, 

 Brunonia. (Pf. IV, 5, 70.) 



Family 278. Stylidiaceae. Australian herbs, with tufted, radi- 

 cal, or scattered and sometimes crowded stem-leaves ; flowers 

 usually irregular ; stamens 2 ; connate with the style. Stylidium, 

 Levenhookia. (Pf. IV, 5, 79.) 



Family 279. Calyceraceae. South American herbs, with al- 

 ternate leaves ; flowers in involucrate heads ; anthers connate ; 

 ovule pendulous. Boopis, Calycera. (Pf. IV, 5. 84.) 



Family 280. Compositae. Herbs, shrubs (and trees), wnth op- 

 posite or alternate leaves ; flowers in involucrate heads ; anthers 

 connate ; ovule erect. Helianthus, Zimiia, Riidheckia, Bidcns, 

 Inula, Antennaria, Aster, Solidago, Eupatormm, Vernonia, Am- 

 brosia, Helenium, Anthemis, Artemisia, Scnecio, Arnica, Calen- 

 dula, Arctotis, Cynara, Cardnus, Cnicus, Mutisia, Cichoriiim, Lac- 

 titca, Taraxaeum. (Pf. IV, 5, 87.) This immense family, of 

 from 11,000 to 12,000 species, is now quite generally broken up 

 into the families Compositae (proper), Ambrosiaceae, and Ci- 

 choriaceac. When treated as a single family the genera (more 

 than 800) are sorted into thirteen tribes. These are of very dif- 

 ferent values, and need revision and rearrangement, and when 

 this is done they may be raised to the rank of families.
