Stipule length

Measure accurately (in mm) length of mature stipules from base to tip.

Stipules are small (commonly less than 1 mm long) appendages found at the base of phyllodes or leaves of most species of Acacia; sometimes they are caducous (i.e. drop off early).

For curved stipules measure along line of the curvature (not a straight line from base to tip).

Best to include a range of measurements (i.e. longest and shortest stipules).

Enter 0 if stipules are absent.

Ignore new shoots.
