Savannosiphon is a monotypic deciduous cormous genus in the Iridaceae family found in southern tropical Africa from southern Congo through western Tanzania. It is in the Watsonieae tribe.
Savannosiphon euryphylla is found in woodland, often associated with termite mounds. It has white flowers with a long perianth tube with the stamens and styles included in the mouth of the tube. Flowers appear one at a time over a succession of evenings. Leaves are pleated, veined, and lanceolate. This species is fragrant, blooms in the evening, and is pollinated by sphinx moths. In my experience the flowers have never had any fragrance but I'm not sure if that is a characteristic of my population. Photos by Nicholas Wightman of plants growing in Lilayi, Zambia.
