Abstract : The ovule was anatropous, unitegmic and pachychalazal and developed into the campylotropous, pachychalazal seed. The undifferentiated seed coat was of dual origin, developing from the integument and the pachychalaza. The term peritesta is suggested for the peripheral, band-like integumentary part of the seed coat. The major saddle-shaped chalazal part was associated with a tanniniferous hypostase. The pachychalazal seed with undifferentiated seed coat probably characterizes the tribe Mangifereae. It is concluded that the Anacardiaceae is one of the more phylogenetically advanced forest families.
