Notes
CORNER (l.c.) stated under Parishia: "It seems that all Malayan species are deciduous and flower before or with the new leaves. P. insignis, however, (like Firmiana) matures even its fruits while the crown is bare of leaves".
Among Malesian Anacardiaceae, Parishia is the only genus in which the fruit is subtended by the much enlarged, wing-like calyx. From the material examined, it appears that after fertilization the increase in size of the calyx takes place much more rapidly than the development of fruit.
The shape, texture, size, indumentum, etc. of the leaflets are very variable in this genus. Specimens consisting of sterile material, young bare infructescences or ♀ inflorescences, or detached young fruits are very difficult to name with certainty.
