The diversity and distribution of the family Asteraceae in four habitat types (dry grassland, wet grassland, cultivated land and roadside) were studied from a region of high mean annual rainfall (Entebbe) to a region of lower annual rainfall (Kafu). Eighty‐eight species belonging to 45 genera and nine tribes of the family Asteraceae were identified with Vernonieae 25% (five genera), Heliantheae 25% (seventeen genera) and Senecioniae 17.1% (six genera) strongly represented. The species diversity of the family Asteraceae was highest in the transition region (Luweero to Katuugo) and similar in the highest and lowest mean annual rainfall regions. Dry grassland habitats are more highly diverse than other habitat types, while roadside habitats are least diverse. Species common to high rainfall areas include Elephantopus scaber L. and Bothriocline longipes (Oliv. & Hiern) N. E. Br. Species more common in low rainfall areas include Aspilia kotschyi (Sch. Bip.) Oliv. and Berkheya spekeana Oliv.
