|petals exhibit a broad yellow center surrounded by a rose-pink border becoming crimson red at the margins. Intensity of the yellow center is dependent on growing conditions. Petal bases and throats are white. Ragged notching and marginal serration of petal apexes and upper margins are evident. Coloration of basal petals is less defined and muted. Petals range from broad, elliptic to ovoid in shape. Tube is white. A magenta-pink stigma is carried above the anthers. Petal recurve is not evident in the photos.
|small, medium green phylloclades have 2-3 forward facing small dentations per side. Upper dentations are larger with deeper areole notching. Basal dentations are small, rudimentary, and occasionally rounded in some phylloclades. Extra apical dentation is evident on a small number of segments.
