as one genus until Anderson pointed out how they differ— 
their characters are so distinctive as to place them in 
different tribes. Hranthemum, Linn., one of the Luellieae, 
has contorted corolla-lobes and foveolate pollen ; Pseuder- 
anthemum, Radlk., one of the Justicieae, has imbricate 
corolla-lobes and banded pollen. ‘There is another and 
more obvious, though less important, difference in the bracts ; 
in Eranthemum these are usually large, in Pseuderanthemum 
they are very small. : 
Cutrivation.—The species of Hranthemum are easily 
cultivated in a warm house. They are best raised annually 
from spring-struck cuttings, and if the tops be pinched back 
during the growing season they quickly form shapely little 
pot-shrubs and flower freely. The well-known /. nervosum 
flowers in winter; the species here figured is at its best in 
July and August.
