CALADIUMS 627 
of the spadix is entirely covered with stamens, whose anthers are shield- 
shaped; the lower part bears the two-celled ovaries, and the intermediate 
portion is covered by blunt glands or sterile stamens. They are natives 
of Tropical America. 
Several Caladiwms were introduced during the 
eighteenth century, but they are not now to be found in 
cultivation in this country. Very few species, indeed, of any sort are 
now grown, their place being taken by the more beautiful hybrids, of 
which there are so many, the list receiving additions every year. 
These are principally the progeny of C. bicolor crossed with other 
species. C. bicolor was introduced from Brazil in 1773; C. maculatum, 
from “South America” in 1820; C. argyrites and C. Chantini, from Para 
in 1858. C. devosianum, C. Hardii, C. Kochii, C. macrophyllum, and 
C. rubro-venium were all introduced from Para in the same year—1862 
—whence also came C. Cannartii, 1863; C. Leopoldi, 1864; C. Rongiert, 
1864; and C. Wallisiz, 1864.
