Euphorbia lactea f. crested variegated (Variegated)

It is a succulent plant of a dark green color and of a characteristic fan shape, which makes it unique in its kind and highly appreciated by green collectors. It has well-marked, pinkish ribs, of a slightly winged shape and with a very evident white-greenish variegation on the whole stem. At its ends small tubercles arise, from which stiff forked thorns grow.
