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
I disclose that my herein invention of a new variety of Digitaria Didactyla grass plant was discovered by me through my cross-pollinating selected varieties of Digitaria Didactyla grass plant then through asexual repropagation selected the new and distinct variety of Digitaria Didactyla grass plant which produces an excellent turfgrass of fine texture with very little thatch buildup, the color of the grass is a moderate green color as defined in the ISCC-NBS Centroid color chart; the stigmas of the new variety of Digitaria Didactyla grass plant are very dark purplish red color as defined in the ISCC-NBS Centroid color chart; the anthers of the new variety of Digitaria Didactyla grass plant are grayish reddish purple color as defined in the ISCC-NBS Centroid color chart; the new variety of Digitaria Didactyla grass plant is glabrous except for a few hairs around the stolon and culm nodes and has a more dense texture.
Show the legal claimThe single numbered claim as granted — the legal text that defines what this patent covers.
Having now described the new and distinct variety of Digitaria didactyla grass plant which I have discovered and asexually reproduced, I claim: 1. A new variety of Digitaria didactyla grass plant herein shown and described by a moderate green color as defined by the ISCC-NBS Centroid color chart; this new variety retains a superior greener color during the winter period by only losing some of its green color, and produces a finer more dense textured surface with a very small amount of thatch buildup; the anthers are a grayish reddish purple as defined by the ISCC-NBS Centroid color chart; the stigmas are of a very dark purplish red as defined by the ISCC-NBS Centroid color chart.
