WillC said:'Ocean' is a hybrid with broader leaves than the standard Chlorophytum, which is what I think you have. In addition, 'Ocean' leaves are all green in the center with the white stripes on the margins of the leaves.

I have collected these plants for years and in my collection I feel sure the plant I have is either a
Chlorophytum comosum 'White Lightning' or Chlorophytum comosum 'Vittatum'). Putting them side by side I am noticing the White Lightning seems to have a thinner leaf. I am 91 years old now and just am not sure. I do not want to give these away or sell them with the wrong ID on them. What do you suggest?
