When it flowers in November and December the tree gives off a startlingly attractive perfume. After the flowers fall to the ground pacas (and perhaps other animals) come to eat them. The attractive aroma of the Pasu flower was attributed to a spirit man inside the tree who has prodigiuos powers of attraction. A young woman could acquire some of the attractive power of the Pasu Flower by entering into a relationship with the Pasu Spirit Man inside the tree. By becoming the wife or lover of the Pasu Man she became the Pasu Spirit Woman who radiated the attractive power and aroma of the Pasu. What follows is a kind of love song to the Pasu man sung by a woman for the purpose of attaining this attractive power. The flowers are followed by an edible fruit the size of a large apple. The appearance of the fruit is thought to be reminiscent of the head of a penis that has become so swollen that it cannot emerge from the foreskin. For this reason, according to Runa yachai (runa custom or belief), men who were fathers of young boys should not eat the fruit less the head of their son’s penis become swollen and unable to emerge from the foreskin.
