‘Saxophone’ Formation with 5-year Sabal minor
by Bob Harms
The 5-year juvenile S. minor in the images below illustrates an advanced saxophone establishment stage. (Clicking on the center of each colored box on the right, will open up a page with an enlargement of that area.)
- At the very top of the yellow box can be seen the remnants of the plumular-radicular node and radicle as oblique downward growth begins.
- Below that area (orange box) the formation of new leaves is forced to develop more or less straight down as the leaf column to its immediate right increases in width.
After 8 leaf scars (blue box) the size of the leaf base increases significantly and the widening of leaf bases would seem to indicate a transition to adult growth mode typical for the subterranean trunk of S. minor.
- In the enlargement of the green box can be seen the leaf veins with a 180° reorientation as the downward growth is suddenly redirected upward.
