Sequences of ITS and nLSU rRNA genes were used for phylogenetic analyses using maximum likelihood, maximum parsimony, and Bayesian inference methods. The three new species of </span><span lang="en-GB"><em>Hyphoderma</em></span><span lang="en-GB"> inferred from ITS sequences and form separate lineages within the genus.</span></span></span></span></p>ZIYAN DUANQIANXIN GUANKAIYUE LUOCHANGLIN ZHAO

<p align="justify"><span style="color: #000000;"><span style="font-family: Times New Roman, serif;"><span style="font-size: small;"><span lang="en-GB">The Overa-Aru wildlife sanctuary is one of the largest protected areas in terms of area (425 km</span><sup><span lang="en-GB">2</span></sup><span lang="en-GB">) in Kashmir Himalaya. Here, we present an annotated checklist of flora of the sanctuary, which includes 397 taxa (392 species, 1 subspecies, 3 varieties and 1 forma) belonging to 254 genera in 76 families. Asteraceae was the dominant family with 57 species, followed by Rosaceae and Lamiaceae with 28 and 27 species respectively. Likewise, </span><span lang="en-GB"><em>Salix</em></span><span lang="en-GB"> and </span><span lang="en-GB"><em>Veronica</em></span><span lang="en-GB"> were the dominant genera with 7 species each, followed by </span><span lang="en-GB"><em>Artemisia</em></span><span lang="en-GB"> with 6 species. The herbs were dominant (307 species, 77.33%) followed by trees (41, 10.33%). Lifespan wise, perennials were dominant (318 species, 80.1%), followed by annuals (66, 16.62%). The hemicryptophytes were the dominant life forms (224 species, 56.42%), followed by phanerophytes (80, 20.15%). Further, nine species occurring in sanctuary are currently recognized under different IUCN threat categories. The checklist provides the first-ever comprehensive documentation of the flora from this Kashmir Himalayan protected area, supplemented with details on natural life-history traits and up-to-date conservation status. Hopefully, the study will be immensely useful in guiding suitable conservation strategies and management planning of protected areas in the region.</span></span></span></span></p>TAJAMUL ISLAMANZAR AHMAD KHUROOIRSHAD A.
