Variation patterns of the characters of flowers and fruits of Berberis replicata W.W.Smith were investigated by field population sampling,checking type specimens and statistical analysis in Tengchong County,Yunnan Province,Southwest China.The research results are shown as below.(1)In May 2013,a total of 53 flowers were sampled from 12 adult individuals of B.replicata.The number of tepals of each flower varied from 13 to 18,mean±SD was 15.25±0.96,among which 34 flowers sampled from 11 adults all consisted of 15 tepals,accounting for 91.67% of the total individuals,and 64.15% of the 53 flowers.In addition,the six inner tepals of each flower,which were opposite to the six stamens separately,emarginated at apex.(2)In December 2013,every 20 ripe berries were sampled from each of 12 shrubs of B.replicata,among the 240 fruits.The seed numbers per fruit varied from 1 to 4,mean±SD was 1.79±0.48,among which 74.17% of the total fruits contained 2 seeds.While in May 2013,150 persistent fruits,which were produced in 2012,were collected from 6 adult individuals of B.replicata,among which,the seed numbers per fruit varied from 1 to 3,mean±SD was 2.11±0.43,and 80.67% of the total fruits contained 2 seeds.Nevertheless,literatures all showed that ovaries of B.replicata,contained only 2 ovules.(3)Among the coefficients of variation in characters of flowers and fruits of individuals of B.replicata,number of petals(0.05±0.03)＜length of fruits(0.07±0.02)＜width of fruits(0.11±0.02)＜length of fruit stalks(0.16±0.05)＜seed numbers per fruit(0.25±0.08)＜length of petals(0.36±0.04)＜width of petals(0.38±0.04).(4)Consequently,the characters of flowers and fruits of B.replicata described in Flora of China are revised,and several photos are provided to fill the gap of the absence of illustration of B.replicata in Flora of China.
