Cyanella alba subsp. flavescens back view and bud

The back view of a Cyanella alba subsp. flavescens flower shows reddish vein lines on the whitish outer tepals. Venation is less distinct on the yellow outer lobe parts of the inner tepals.

The pointed, ovoid bud present lower down shows more outer tepal venation (Manning and Goldblatt, 1997; iNaturalist).
