Fl. 108 mm wide, snow white; perianth segments broad, notched at apex, slightly inflexed; corona slightly ribbed, with mouth slightly expanded, rim crenate.

A description according to Michael Jefferson-Brown’s 1962 Catalog: “An Award of Merit flower, a most perfect show one. Buds open and reveal glistening snow flowers, and as they open so they remain, without the suggestion of cream. White somewhat pointed petals, like a perfectly disciplined team, form a perianth pressed and starched at right angles to the fine-spun crown. ‘Purity’ is a lucky name for it. The crown is shorter than ‘Arctic Dorie’s’ but as much of the same chaste shape and is snow white. The mouth of the crown is only widened a very little. It has good white breeding, 33/69 x Snowline. The plant grows well and stems stand tall and strong, those of the vaseful gaining its A.M. were 22″ – 25″.”
