(1)Meiotic studies of 4 spp. and 3 hybrid varieties of Mussaenda [M. flava, M. galbrata, M. erythrophylla, M. philippica var. Aurorae] were made. The chromosome number was n = 11 in all the cases. Meiosis was normal in the 4 spp. The hybrids examined showed various abnormalities and high pollen sterility. Two species, M. galbrata and M. flava showed exceptional pollen development in which the vegetative nucleus breaks up and the nuclear fragments are included in pollen buds which are subsequently shed from the pollen. [No evidence of natural hybrids]
