NB 1: Foliage span = the distance from the stem to the ground projection of the tip of frond 33. NB 2: Percentage of foliar overlap = by projection of the foliage volume (assimilated to a sphere) on a plane: part of the area of a unit triangle covered by the foliage of 2 or 3 palms (graphic determination).
