Because of the large amount of nectar flow observed from the tuliptree (Lirodendron tulipifera), an experiment was undertaken to determine the quantity of nectar secreted per blossom and the sugar content of this nectar. The average weight of nectar secreted by one flower was 1.6417 grams. The average sugar content of nectar from freshly opened blossoms was 16.7 per cent. After the flower was open the concentration of the nectar increased until on the second day it reached 35.9 per cent". The tree under observation was calculated to yield sufficient nectar to produce 2.16 pounds of honey.
