The taxonomy of 6 species of Sida in Nigeria is discussed and a key produced. The taxa recognized and treated are S. linifolia Jussieu ex Cavanilles, S. cordifolia L. var. cordifolia, S. cordifolia L. var. alba Ugborogho var. nov., S. pilosa (Retzius) Ugborogho, S. urens L., S. spinosa (L.) Ugborogho and S. ovata Forskal. The distribution of the 6 spp. is considered. While species like S. linifolia and S. cordifolia are country-wide in their distribution, others like S. spinosa and S. ovata are more or less limitedto the northern parts of the country. S. pilosa and S. urens are also located in both halves of the country but in smaller populations. They are much more common in the north central and southwestern parts of the country.
