Aylostera crassa WR642 (incorrect number)

Although we have this plant labelled Aylostera crassa WR642 in the collection, grown from seed supplied by a German nursery, it is not this field number. The number relates to Aylostera canacruzensis and is a delicate pink or white flowered plant. We suspect a mistake has been made by the seed merchant since “crassa” and “canacruzensis” are next to each other on a list.
