A hybrid seedling is an orchid plant that has been produced by seed through the hybridization process. Two parent plants were used to produce the seed and the individual seedlings all have their own unique characteristics, like brothers and sisters in a family. A meristem seedling is a seedling that has been produced using the cloning process. Each "mericlone" plant has an identical genetic make-up and each meristem or mericlone plant will look exactly the same, like identical twins.
