R. watsoni - Japan. A most peculiar form that had been dubbed by Dr. Van Fleet "The Bamboo Rose." The foliage does not look like any other rose, being so finely cut and irregular. A low compact bush with very small flowers that come and go unnoticed. A curious monstrosity! Not very hardy. Evidently, what hybridizers call a "chimera."
