  Tubers used as chikanda (Golding in Sabonet News 6/2: 99, 2001; P. Latham, Plants visited by bees… useful plants Umalila… : 167, 2007). Tubers and cakes (flour baked into cakes to be eaten with tea) are sold in markets in the Southern Highlands of Tanzania. Closely resembling S. chlorocorys. In the herbarium small specimens of S. shirense are difficult to distinguish from S. chlorocorys, but in the field they appear quite distinct (Fl. Zambes. 11/1: 217-218, 1995). The two species grow together in N Malawi, but no intermediates between them have been seen.
