Paph. Sierra Bell is a complex brachpetalum type hybrid with large white flowers with red spots. It was crossed with Paph Spellbound, a dark red vini colored maudiae type with a Paph. sukhakulii background which gives it wide petals. Flowers are very variable and range from a light pink with small purple spots to a rusty pink to a dark red. The picture above shows one of the "darker" forms.
