Cactaceae plant

PUBLIC DOMAIN

Patent expired January 24, 1995. This plant is in the public domain — anyone may propagate and sell it.

Twenty years from the filing date would end on January 18, 1997, but this patent ends 725 days earlier — a terminal disclaimer gives term back. A source that calculates twenty years from filing would tell you this plant is still protected when it is already free.

No cultivar name of record

This patent does not name the plant, and for its era that is ordinary rather than an omission. Before about 1980, breeders frequently patented a plant without giving it a cultivar name at all — the grant identified it by its number, its parentage and a written description of the flower and foliage. Most plant patents from the 1930s to the 1970s have no name in them.

Nothing here is missing from our records: the patent itself states no name. Where one exists we show it, and we do not invent one.

Abstract

A new and distinct plant variety of the Cactaceae family has a generally "purplish" colored bloom with the color in the marginal blade areas of the perianth tube laminating and forming series of tepals being dominated by a reddish purple hue. The tepals of the bloom have generally greater width dimensions in comparison to correspondingly located tepals of the `Lavender Doll` variety and those of the perianth tube laminating series emerge generally closer to the distal end of the perianth tube than those of the `Lavender Doll` variety so that the bloom in comparison is fuller and with a more compact tepal arrangement. The life of the bloom ranges from about 6 to about 9 days. The stems in comparison to the `Lavender Doll` variety, have fewer branches, generally longer phylloclades and somewhat thicker wings.

Show the legal claimThe single numbered claim as granted — the legal text that defines what this patent covers.

We claim: 1. The new and distinct plant variety of the Cactaceae family as described and illustrated and which has a growth habit providing specimens that combine the following principal distinguishing characteristics: 1. A generally "purplish" colored bloom with the color in the marginal blade areas of the perianth tube laminating and forming series of tepals being dominated by reddish purple hue, 2. A bloom with tepals having generally greater width dimensions in comparison to correspondingly located tepals of the `Lavender Doll` variety and including perianth tube laminating tepals which emerge generally closer to the distal end of the perianth tube than those of the `Lavender Doll` variety, whereby the bloom of the new variety appears fuller and with a more compact tepal arrangement than exhibited by the `Lavender Doll` variety, 3. A bloom with a perianth tube that is basically translucent white and/or in color dominated by yellowish pink and/or purplish pink hues, 4. A bloom life of from about 6 to about 9 days, 5. Stems having fewer branches and generally longer phylloclades with thicker wings in comparison to those of the `Lavender Doll` variety.
