One of the better collections of stonei resides in Columbus, Ohio. This collector has some dozen or two different named clones of stonei. Over the years I've seen a number of them bloom. Most have a few stripes in their dorsals, 2 or 4 is the most common, but several clones bloomed like this with no stripes at all. Any stonei in bloom is a beauty, and I do like the clean white of these no-stripes-havin' clones. No stripes is a less than common but perfectly normal variant for the species.
