Data from: Taxonomic revision of the genus Tzveleviochloa (Poaceae, Aveninae) in India

The taxonomy of Tzveleviochloa in India is revised based on morphological evidence, comprehensive observations of herbarium specimens and field records, and several botanical explorations in the study area. The accepted diversity is increased from two to five species, including two recently described species. The genus is distributed in the Western and Eastern Himalaya and the Western Ghats. Pilose hairs on leaf blades can distinguish species, along with panicle shape and size, glume nerves, lemma, and anther length. We present a comprehensive taxonomic treatment of the genus Tzveleviochloa, including a description of the genus and its species, taxonomic keys, flowering and fruiting, habitat and distribution comments, and taxonomic notes. In addition, we discussed the history of the genus, its morphological details, geographic and altitudinal distribution, and a preliminary assessment of conservation threats.
