This paper is a continuation of two previous papers on the genetics ofRanunculus bulbosus andR. acris. Characters studied are flower colour and sex in both species, poor development of petals in the former and leaf blotch in the latter species. Evidence is given that these have all a genetic basis, but the ratios are often disturbed by the occurrence of apomixis and, particularly inR. acris, semi-lethality and perhaps of lethality with certain gene combinations.
