Nang Yaem (Cleredendron fragans). A shrub having fragrant flowers. It is easily propagated as its roots run far and wide underground and shoot up as new plants until they become a nuisance. The people believe that Nang Yaem will turn into a "phi" when it grows old, and disturb the peace of the house by pelting stones at it. Nang Yaem in Thai means to open slightly in bloom or the peeping of a damsel, hence its poetic name is found quoted in Thai erotic literature.
