This exceptional variant of B. versicolor is different from the standard versicolor primarily in the color and width of the striping. It is named after Charlot Teng. In the standard versicolor the leaf venation is red, with mostly green foliage. This one has thicker, more purple banding over the leaf venation. The in-between is minty-green. The texture also seems a bit more velvety than the standard type, maybe due to smaller hairs on the foliage. It is a compact species suited to terrarium culture.
