Revision of the genus Murdannia (Commelinaceae) in India Mayur D. Nandikar & Rajaram V. Gurav- Phytodiversity 2015: Vol. 2 (1): 56-112-
Abstract : A taxonomic revision of the genus Murdannia (Commelinaceae) in India is presented based on field and herbarium studies. Twenty-seven of the fifty-five species in the genus are recognized and it becomes the first largest genus in Indian Commelinaceae. Detailed descriptions of all species including key, illustrations, distributions, specimen citations, colour photoplates and SEM photographs of seeds are provided. Lectotypifications of eight binomials, one neotypification, two new statuses and one new variety described during this work are also dealt with.
