Note: The material cited from Gopnath, Gujarat, India by Sreenivasa Rao & Kale (1970) had been previously assigned by those authors (1969: 273) to a new variety, Gelidiella myrioclada var. vasudevayae. That varietal name is invalid, however, since its authors failed to satisfy the requirements of Arts. 36.2 (Latin diagnosis), 37.1 (indication of type), and 39.1 (illustration).
