Size of matured flowers are generally the same size all the way up the sample. There are no sepals at the bottom of the flower. . The cluster of red coloured flowers would attract pollinators. The stigma curves under to the petal where the male organs are located. Once matured the stigma extends for pollination, where once a pollinator has landed on the flower, the stigma rubs on the back of this pollinator which then transports pollen to another flower enabling pollination to occur. This process prevents self-pollination.
