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 which produces an excellent turfgrass of superior moderate bluish-green color as defined in the ISCC-NBS centroid color chart; the anthers of the new variety Digitaria Didactyla are dark purple as defined in the ISCC-NBS centroid color chart; the stigmas of the new variety of Digitaria Didactyla are strong reddish-purple as defined in the ISCC-NBS centroid color chart; the new variety of Digitaria is glabrous on the sheath and in between the internode and has a more open texture.
