Item Some observations on the reprodutive biology of three species of Lonicera L. (Caprifoliaceae)(1984-85) Gunatilleke, L.A.U.N.; Gunatilleke, C.V.S.Breeding experiments with two introduced species, Lonicera deflexicalyx balt., L. gracilipes Miq. compatible, but the capacity for out-crossing and successful open-pollination to be significantly greaterthan that for selfing. Stigma receptivity during the entire period of bloom in all three species suggests an exception to the protandrous condition previously suggested for this genus. Interspecific crosses between these species result in fruit yield ranging from 25091 percent which may account for the phenotypic variation observed among cultivated plants of these speciesItem A floristic survey of a unique lowland rain forest in Moraella in the knuckles valley, Sri Lanka(University of Peradeniya.
