In both the localities, <i>C. nandadeviensis</i> was found growing associated with <i>Briza media</i> Linnaeus (1753: 70), <i>Bromus catharictus</i> Vahl (1791: 22), <i>Dactylis glomerata</i> Linnaeus (1753: 71), <i>Festuca ovina</i> Linnaeus (1753: 73) and <i>Poa alpina</i> Linnaeus (1753: 67) at an elevation ranging from 3400 m to 3700 m in alpine meadows. The Valley of Flowers National Park, Uttarakhand is well known for plant diversity and endemism. About 28 species of grasses have been reported in this region (Bisht <i>et al.</i> 2018). On the other hand, Rohtang Pass is a high mountain pass situated on the eastern Pir Panjal Range of the Himalayas at about 51 km from Manali in Himachal Pradesh. It demarcates Kullu valley from Lahaul Spiti valley in Himachal Pradesh. These regions are characterized by large range of alpine meadows, an open habitat in which grass and non-woody plants are predominately present. As the Valley of Flowers National Park is a protected area, so vegetation of this place is intact from external anthropogenic pressure whereas, Rohtang Pass is an unprotected area, open for tourists and local people, which render its vegetation threatened. Plants growing in this region face anthropogenic threats cause due to overgrazing by animals, increased tourism, etc., and hence the plant diversity is at a risk of extinction in the future.</p> <p> <b>Etymology:—</b> The species is named after its type locality Nanda Devi Biosphere Reserve.</p> <p> <b>Taxonomic notes and remarks:—</b> <i>Calamagrostis nandadeviensis</i> is closely allied to <i>C. lahulensis</i> and <i>C. scabrescens,</i> distributed in Himalayan Region and, often similar to <i>C. nagarum</i> (Bor) G. Singh (1984: 94), known only from north-east India (Bor 1960, Kellogg <i>et al.</i> 2020) and two other species known only from China and Myanmar, <i>C. himalaica</i> (Liou ex Chen) Paszko (2015: 142) and <i>C. nyinghchinesis</i> (P. C. Kuo & S. L. Lu) Paszko (2016: 51), which are collectively recognized by similar length of spikelet, more or less scabrid glume and geniculate awns inserted nearly at the middle or above the middle of the dorsal surface of the lemma (Bor 1960, Noltie 2000, Lu & Philips 2006, Paszko 2014). <i>C. nandadeviensis</i> differs from <i>C. lahulensis</i> and <i>C. scabrescens</i> in circumscriptions of habit, leaf blade, ligule, panicle and spikelet (Table 1. Fig. 4.), whereas clearly distinguishable from <i>C. nagarum</i> by having leaf blade 8–15 cm long (vs. 15–30 cm long), ligule 6.1–7.8 mm long (vs. 1–2 mm long) and panicle 7–12 cm long, lanceolate (vs. 12–20 cm long, ovate) (Shukla 1996). However, <i>C. himalaica</i> is recognized by spikelet occasionally bearing 2- florets and awn 4.5–10 mm long, which is conspicuously exerted from spikelet (Paszko 2014) and <i>C. nyinghchinesis</i> by shorter length of anther, that is 0.7–1.1 mm long (Paszko 2016), therefore, <i>C. nandadeviensis</i> is clearly distinct from them.</p> <p> <b> Additional specimens examined:— <i>Calamagrostis nandadeviensis sp. nov.</i> (paratype):</b> INDIA. <b>Himachal Pradesh</b>, Kullu, Manali, on the way to Rohtang pass, near Maharishi Vedvyas temple, 32.359364N, 77.230075E, 3673 m, 5 August 2019, <i>D.

Most Popular Aesop's Fables
No full textThere are twenty-seven fables here in a paperback book measuring 4¾ x 7. There is a T of C at the beginning. Each fable gets one full-page black-and-white illustration. Black-and-white is not quite accurate, since these illustrations incorporate effective shading. The endearing feature of this book is these cartoon illustrations. They are on the way to something like the cartoons for Far Side. Notice, e.g., the anger on the face of the farmer as he approaches--with stick in hand--the dog in the manger (10). And for TMCM just following, there are fine expressions on each of the mice's faces (14). Here, as in other recent Indian fable books, the Jump in Rhodes story--or something quite like it--is told with a cat as the boaster (23).First editionRetold and Illustrated by Abrar Nari, Rudra Prasad Warrier, and Shane Brow

Going Beyond Counting First Authors in Author Co-citation Analysis
No full textThe present study examines one of the fundamental aspects of author co-citation analysis (ACA) - the way co-citation
counts are defined. Co-citation counting provides the data on which all subsequent statistical analyses and mappings
are based, and we compare ACA results based on two different types of co-citation counting - the traditional type that
only counts the first one among a cited work's authors on the one hand and a non-traditional type that takes into
account the first 5 authors of a cited work on the other hand. Results indicate that the picture produced through this non-traditional author co-citation counting contains more coherent author groups and is therefore considerably clearer. However, this picture represents fewer specialties in the research field being studied than that produced through the traditional first-author co-citation counting when the same number of top-ranked authors is selected and analyzed. Reasons for these effects are discussed
