No cultivar name of record
This patent does not name the plant. Through the 1980s and early 1990s that was still common: naming every new cultivar only became standard practice as plants began to be marketed under brand names. The grant identifies this one by its number and by a written description instead.
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.

A self-heading Philodendron plant having uniquely shaped leaves with pronounced lobes that are distinctly hooked. New leaves are moderate reddish brown. Overall color of the plant is reddish to rich-green with reddish brown colored petioles.
Show the legal claimThe single numbered claim as granted — the legal text that defines what this patent covers.
I claim: 1. A new and distinct variety of Philodendron plant, substantially as herein shown and described, characterized particularly as to novelty by the unique combination of self heading growth habit, distinctive hooked, lobed leaf form, the leaves with reddish brown coloration, which ultimately produce a plant having overall reddish coloration enhanced by moderate light, freedom from "shot gun" fungus problems, upright symmetrical growth without requiring staking and average height of eighteen to twenty four inches in about one year.
