“…The shape of the embryo sac in Sanango with a narrow chalazal portion and a broad micropylar portion is similar to what has been described for genera of Budlejaceae, Scrophulariaceae and Gesneriaceae (Arekal 1963a and b;Awasthi 1991;Bhandari 1976Bhandari , 1985 ' The EODP system is based on: E, the cellular or nuclear nature of the endosperm development; 0, the orientation of the wall formed during the first mitotic cycle; D, the destinity of the daughter cells produced by the first division; and P, the position of the walls produced during the second mitotic cycle.

An embryological study was undertaken in the Amazonian genus Sanango in an attempt to help clarify the relationship of the genus. Detailed description of microsporangium, microsporogenesis, microspore, ovule, megasporogenesis, embryo sac and development of the endosperm are presented. The results confirm that Sanango is undoubtedly related to the Scrophulariales but it remains to be determined what the most satisfactory assignment of the genus should be. On the basis of early endosperm development, Sanango appears as closely related to the Gesneriaceae as well to the Scrophulariaceae. Further studies of embryonic stages and seed coat development would be helpful in clarifying this relationship. The other embryological features studied here seem not to be of taxonomic importance. A closer relationship with the Loganiaceae (Gentianales) is improbable.
