        ++ large, brightly coloured petals
        
        ++ nectar guide & nectar
        
        ++ sweet-smelling
        
        -- fairly abundant pollen grains that are rough and large
        
        -- small, compact stigma that is not protruding out
        
        -- non-pendulous filaments & non-protruding anthers
        
        ++ species more well-adapted to change in environment
        
        ++ higher chance of survival
        
        transfer of pollen grains from the anther to the stigma of different plants of same species.
        
        Wind-pollination
        
        -- small, dull-coloured petals
        
        -- no nectar guide & nectar
        
        -- odourless
        
        ++ abundant pollen grains that are smooth and tiny

        ・A & S mature at same time ・S directly under A
        
        Self-pollination
        
        ++ less pollen & energy wasted
        
        the transfer of pollen grains from the anther to the stigma of same/different flower in the same plant.
        
        ++ higher probability of pollination
        
        ・A & S mature at diff timings ・S not directly under A
