Small, nodding or out-facing, yellow flowers with cream anthers on purple filaments. This form originated with Crûg Farm Plants in North Wales as szuyuanensis which they had collected in the wild from N Taiwan. Van Zoest in Holland wanted to propagate from a plant they had obtained but Crûg Farm initially denied it was their form, although later they agreed that it was. In the meantime, Wim Snoeijer at Van Zoest named it - the 'mysterious' referring to its (then) disputed origin.
