Kin Groups and Descent. In most areas, segmentary descent groups are ordered by patrilineal descent. In parts of Adonara, descent groups appear to have lost significance and have been replaced by the patripotestal family. In the extreme west, descent is matrilineal.
Kinship Terminology. The relationship system varies in detail from village to village. All terminologies recorded to date are ordered by patrilineal descent and a matrilateral marriage prescription.
