The hemi-parasitic genus Pedicularis Linnaeus (1753: 607) contains about 671 species, distributed mainly in temperate to tropical mountains and subarctic area of the world, and is the largest genus of the family Orobanchaceae (POWO 2020, Borah et al. 2020, Garg et al. 2020). Presently, 86 species, 13 subspecies and 9 varieties are known from India,...

... and Solukhumbu by H. Ohba in 1985 housed at TI (Yamazaki 1988). The present collection from Arunachal Pradesh is a rediscovery of this species from India after a lapse of about 135 years confirming the second locality for this Country. Extended taxonomical description, habitat, phenology and color plates with the first available live photographs (Fig. 1) Annual, erect herbs, 15-50 cm high (including inflorescence), not becoming black after drying. Stem solitary or 2-8 from the root, glabrous or sparsely pubescent below, densely above. Leaves both radical and cauline, pinnatifid; radical evanescent, 5-9 mm long, oblong-lanceolate, pinnatifid, pubescent on both surface; segments 3-4 ...

... Chauhan 1997, Jahan et al. 2018) the Sikkim state comprises a wide variation in vegetation ranging from tropical, subtropical, temperate to alpine and constitutes a megadiversity centre of the hemi-parasitic genus Pedicularis (Orobanchaceae) in India. The genus comprises about 677 species worldwide (POWO 2022) with 82 species, 13 subspecies and 9 varieties in India ) of which, 14 species, 2 subspecies and 4 varieties are endemic (Borah et al. 2020a, b, Garg et al. 2020a, b, Singh et al. 2016. Commonly known as 'Louseworts', the plants are remarkably microhabitat-specific (Garg and Husain 2009) annual or perennial herbs. ...
... The scattered small population patches of this plant spread inwards within the partially shaded regions of the forest. Comprehensive literature consultation on the genus Pedicularis (Hooker 1884, Prain 1889, 1890, Pennell, 1943a, Li 1948a, b, 1949 Yamazaki 1988, Yang et al. 1998, Husain and Garg 2003a, b, c, Garg 2009, Garg and Singh 2015, 2020, Borah et al. 2020a, followed by critical taxonomic studies conducted on the collected material for it's macro-and micro-morphological characters, including pollen morphology, showed that among all the species of Pedicularis, the present, unique species is nearest allied to Pedicularis gracilis Wall. ex Benth. ...
The new species Pedicularis revealiana, is described from Katao in Sikkim Himalaya, India. The new species is hemiparasitic and possesses a combination of characters which makes it unique among all Pedicularis species as it has a perennial caespitose habit, stout and woody stems with decumbent branches and congested internodes, evanescent radical leaves and smaller and fewer cauline leaves with linear pinnae, 3-5 flowered and subcapitate or fascicled inflorescence, pedicillate bracts, minute flowers, hairy calyx with crestate-dentate and recurved lobes, stipitate and arcuate galea with truncate apex and papillose surface, gland-dotted labium with very large lateral lobes, unequal filament pairs inserted near top of the corolla tube, stipitate stigma which is bilobed and woolly and monocolpate pollen grains which are large and fusiform in shape with rugulose-punctate surface. With these combination of characters, it is differentiated from the only allied species Pedicularis gracilis.
... Pedicularis L. encompasses more than 677 species worldwide, sparingly but widely dispersed (Baasanmunkh et al., 2021;POWO 2022) and forms the largest genus in the family Orobanchaceae. For the Indian flora, 84 species, 13 subspecies, and 9 varieties have so far been identified, with 17 species, 4 subspecies, and 5 varieties being endemic (Garg, 2009;Husain et al., 2010;Singh et al., 2016;Borah et al., 2020aBorah et al., , 2020bGarg et al., 2020). Pedicularis commonly called 'White Lousewort' is one of the important taxa described by Linnaeus in 1737. ...
The herb Pedicularis cheilanthifolia var. albida (Pennell) P. C. Tsoong is reported and collected for the first time from the Rudraprayag District of Uttarakhand. The species was seen growing along a glacial stream in an alpine region between 4,100 and 4,400 m asl. Morphological characteristics of the species were examined and processed for herbarium deposition. To simplify taxon identification, a brief taxonomic description and illustration of the taxon are provided.
Herein, we present the first record of Henckelia longipedicellata (B.L.Burtt) D.J.Middleton & Mich.Möller (Gesneriaceae) for the flora of India based on specimens from Mayodia, Mishmi Hills, Lower Dibang Valley district of Arunachal Pradesh, India and its rediscovery after type collection. This species is easily recognized due to its solitary flowers with longer peduncles, deeply divided calyx lobes and ventrally pouched campanulate corolla. H. longipedicellata is so far known from Myanmar. A brief description along with additional notes and photographs are provided.
Cremanthodium indicum D.Borah, R.Kr. Singh & Thungon (Asteraceae, Senecioneae), a new species from Eastern Himalayan state Arunachal Pradesh, India is described and illustrated. The new species is allied to Cremanthodium nobile (Franch.) Diels ex H.Lév. in having elliptic-obovate basal leaves, solitary, nodding capitula and hemispheric involucre, but differs by densely pale yellow tomentose stem, stem leaves 5-9, 1.6-2.1 cm distant, outer phyllaries 2.3-2.8 mm wide, inner phyllaries elliptic, 3-5 mm wide, apex acute, ray lamina creamy, oblong, 2-2.3 cm long, apex truncate, distinctly 3-dentate, ray tube 1.5-2 mm long, tubular florets creamy, 8-9 mm long and pappus 6-8 mm long.
