US Plant Patent PP4200

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, 1996, but this patent ends 359 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 plant variety of the Cactaceae family is related to the `Kris Kringle` and `Lavender Doll` varieties of the truncatus species and Zygocactus genus and has a growth habit providing specimens that combine the following principal distinguishing characteristics: a fast growth rate as comparable to that of the `Kris Kringle` variety; a natural tendency to branch without inducement by pruning during the growth period prior to blooming and which is comparable to that of the `Kris Kringle` variety; resistances to nutrient deficiencies and fungus type diseases that are comparable to those of the `Kris Kringle` and `Lavender Doll` varieties; a substantially greater resistance to flower bud abscission in comparison to the `Lavender Doll` and `Kris Kringle` varieites; and a bloom with less recurve in the tube forming tepals in comparison to the `Kris Kringle` variety and which commonly occurs from about 2 to 4 weeks earlier than blooms of the `Peach Parfait` variety, and having a bloom life of from about 6 to 9 days, a shorter style and perianth tube than those of the `Kris Kringle` and `Lavender Doll` varieties and perianth tube laminating and forming tepals with marginal blade areas that in color are dominated by pink, yellowish pink, red and/or reddish orange hues.

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 variety of the Cactaceae family substantially as herein shown and described and which has a growth habit providing specimens that combine the following principal distinguishing characteristics: 1. A fast growth rate as comparable to that of the `Kris Kringle` variety, 2. A natural tendency to branch without inducement by pruning during the growth period prior to blooming and which is comparable to that of the `Kris Kringle` variety, 3. Resistances to nutrient deficiencies and fungus type diseases that are comparable to those of the `Kris Kringle` and `Lavender Doll` varieties, 4. A substantially greater resistance to flower bud abscission in comparison to the `Lavender Doll` and `Kris Kringle` varieties, and 5. A bloom with less recurve in the tube forming tepals in comparison to the `Kris Kringle` variety and which commonly occurs from about 2 to 4 weeks earlier than bloom of the `Peach Parfait` variety, and having a. a bloom life of from about 6 to about 9 days, b. a shorter style and perianth tube than those of the `Kris Kringle` and `Lavender Doll` varieties, and c. perianth tube laminating and forming tepals with marginal blade areas that in color are dominated by pink, purplish pink, yellowish pink, red and/or reddish orange hues.
