Table 2 in The floral scents of Nymphaea subg. Hydrocallis (Nymphaeaceae), the New World night-blooming water lilies, and their relation with putative pollinators

Table 2 Chemical composition (amounts of each compound) of the floral scent of seven species of Nymphaea subg. Hydrocallis (Nymphaeaceae). Floral scent samples were obtained by dynamic headspace during the interval of highest perceivable odor emission in the course of the pistillate (day 1; $) and staminate (day 2; #) phases of anthesis.
