Peduncles are more intensely reddish-infused than in K. ×hankeyi, but less than in K. sexangularis. D. Flowers (corolla tube and corolla lobes) are more intensely yellow than those of either of the parents. E. Flowers, here in lateral view, of K. ×sampsonii (centre) are often intermediate between those of K. longiflora (left, one of the parents of K. ×hankeyi) and K. sexangularis (right), but the corolla tube is more intensely yellow. F.
