Caladium Bicolor, rather plain parents of many of 
our present fancy-leaved Caladiums, growing in the 
alluvial clay of the Amazon basin in South America. 
The Easter Orchids Cattleya mossiae, are collected 
in the high, cool forests of Venezuela, and sold over

of Guiana grows Monstera pertusa, not as good a

the drier climate of Mexico. 
Giant blue Column Cactus, probably Cereus hex- 
agonus, in the Rio Cauca Valley in the High Cor- 
dilleras of Colombia. A few miles to the west on 
the moist Pacific slope we find a large assortment 
of Dieffenbachia, Anthuriums and other aroids.
