Two axillary buds. 



Terminal bud. 

 FIG. 1 (b). THE SAME. Showing the scars left by the falling off of the bud-scales. These scars mark the

The peculiarity of the Onion is this : it remains permanently in the bud condition. A 



permanent bud of that kind is called a bulb.

Foliage leaves the green leaves which manufacture starch (L. folium, the leaf).
