Abstract: In this paper, conven-tional pressed slice method was used to study chromosome number and karyotype of four herbaceous flowers. The results showed that Diranthus chinensis:chromosome number 2n=14, karyotype formula K(2n)=14=12 m+2 sm, belonging to “1A” type; Lavatera trimestris Linn :chromosome number 2n=14, karyotype formula K(2n)=14=6 m+8 sm, belonging to “2A” type; Capsicum frutescans :chromosome number 2n=24, karyotype formula K(2n)=24=24 m, belonging to “1B” type; Impatiens balsamina :chromosome number 2n=14, karyotype formula K(2n)=2x=14=10 m+4 sm, belonging to “1B” type. This is the first report of karyotype of these four flowers, and may help breeding and classification of flowers.

Key words: Diranthus chinensis, Lavatera trimestris Linn., Capsicum frutescans, Impatiens balsamina, Chromosome, Karyotype
