308 SPECIES BLANCOANAE 
evident that the form currently interpreted as Limnanthemum

The Linnean species was undoubtedly correctly interpreted

is still commonly cultivated for ornamental purposes in the 
Philippines.

as calachuchi, calosasi, carachucha, calonoche, ete. It is found 
only in cultivation here and never produces fruits.

I can see no reason for considering that more than one species 
is included in Echites trifida Blanco and Alstonia batino Blanco, 
although Fernandez-Villar reduced the former to Alstonia specta-
