I looked in the (very old ) book of Esau It indeed does not
contain a definition of a cotyledon nor a picture of a germinating
monocot. On p726 is a picture of an Allium seed . The cotyledon as
shown will grow out first pushing out the apex but stays connected
with the seed to extract food from the endosperm via the terminal
part of the cotyledon, the haustorium. Therafter the first
true leaf will arise from the place mentioned in the picture as
"epicotyl apex".I hope you ( Joe) and others are convinced now. If
not ask again
