MORPHOLOGICAL AND
ONTOGENETICAL STUDIES
Using Bonnet's method, the ontogeny of tassel and ear was studied in some indigenous South American races of maize, in Euchlaena and in Tripsacum. A complete homology was found in all details, and there is an especially close relation between Tripsacum (australe and dactyloides) and Euchlaena (Novogame and other types). A full report is nearly ready for publication.
It should be noted that a very great amount of parallel variation occurs.
