Abstract

A comparative study of four morphologically similar taxa namely Fimbristylis aestivalis (Retz.) Vahl, F. squarrosa Vahl var. squarrosa, F. squarrosa var. esquarrosa Makino and F. griffithii Boeckeler has been undertaken and the findings are discussed in detail. Some of the diagnostic features, such as hairiness of the leaves, straight or recurved mucro of the glumes, presence or absence of cilia on the style and presence or absence of long pendent hairs at the style-base can be used for differentiating these taxa unambiguously. Fimbristylis griffithii is reported for the first time from Arunachal Pradesh and West Bengal. Keywords: Fimbristylis, Identification, India, New report, Similarity, Taxonomy.
