A rectoscope has a tube and a handle protruding therefrom. The surgical instrument exits at an intermediate position of the guide tube and is oriented to be substantially parallel to the guide tube’s longitudinal axis as it exits. This invention relates to the hybrid seed 31R88, the hybrid plant produced from the seed, and variants, mutants, and trivial modifications of hybrid 31R88. Numerous other aspects are provided. The film is transparent so that the printing on the substrate can be seen through the film.
