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.
Abstract
A Philodendron plant of very compact rosette form having thick narrowly ovate to elliptic leaves, the leaves being dark-brick red becoming dark-reddish-green when mature. The petioles are black-red, short, thickened and prominently winged.
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 compact rosette form with thick narrowly ovate to elliptic leaves, which are dark, brick-red color as new leaves becoming dark-reddish-green at maturity, petioles of black-red, short thickened prominently winged form, presenting over all a very compact, bushy, spreading plant of a height substantially less than its spread.
