... Rhynchotechum Blume has been revised recently by Anderson and Middleton (2013) who recognized a total of 16 species, excluding the recently described species: R. nirijuliense Taram & D. Borah (Taram and Borah, 2020) (Anderson and Middleton, 2013;Sinha and Datta, 2016;Möller et al., 2017;Roy, 2017;Roy et al., 2019;Taram et al., 2020;Taram & Borah 2020) from which nine species (with the exception of R. permolle) are distributed in North East India while R. nirijuliense and R. calycinum are reported to be endemic to Northeast India. Among the ten species, eight species of Rhynchotechum have been reported from Arunachal Pradesh (Anderson and Middleton, 2013;Sinha and Dutta, 2016;Roy et al., 2019;Taram and Borah, 2020;Taram et al., 2020a) but the present field investigation has recorded seven Rhynchotechum species with immense foliar and floral diversity found in the state of Arunachal Pradesh. ...
A taxonomic investigation on the genus Rhynchotechum Blume (Gesneriaceae) in the state of Arunachal Pradesh, India was carried out during 2018-2022. The present revisionary studies have reported 7 taxa from Arunachal Pradesh. All the recorded species are enumerated here with taxonomic keys and notes based on morphological characters of living plants, along with the distributional ranges and colored photographs.
... Singh (Taram et al., 2021). While working on the floristic diversity of Eastern Himalayan state Arunachal Pradesh, India (Borah et al. 2019(Borah et al. , 2020dTaram et al. 2020aTaram et al. , 2020bTaram et al. , 2020cTaram et al. , 2021, the authors encountered an interesting species of Henckelia. Detailed study of Henckelia species of India and adjoining countries, including protologues, type specimens, other herbarium specimens and relevant taxonomic literature (Clarke, 1874(Clarke, , 1884Chatterjee, 1948;Don, 1825;Kanthraj et al., 2020;Krishna & Lakshminarasimhan, 2018;Sinha & Datta, 2016;Sirimongkol et al., 2020;Taram et al., 2020bTaram et al., , 2021Wang et al., 1998;Wood, 1974;Yang et al., 2019) ...
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.
... State is inhabited by 26 major tribes and 110 sub-tribes with rich traditional knowledge related to sustainable utilization of ethnobotanical species (Tag 2007;Taram et al. 2018). Recently, Roy (2017) and Taram et al. (2020) have reported some ethno-botanically significant species of Gesneriaceae like Rhynchotechum ellipticum, Rhynchotechum parviflorum and Boeica fulva from North East India. However, detail ethnobotanical studies are required for conservation and sustainable utilization. ...
The present ethnobotanical investigation reports 21 species of Gesneriaceae used by the indigenous tribal communities namely Adi, Galo, Nyishi, Tagin, Tangsa and Lisu of Arunachal Pradesh. Rhynchotechum parviflorum, Rhynchotechum ellipticum and Boeica fulva were found abundant and widely used as both food and medicinal purposes. However, Rhynchotechum nirijuliense, Rhynchotechum ellipticum, Rhynchotechum parviflorum and Rhynchotechum obovatum have showed highest use value (UV) indicating their ethnobotanical and cultural significance to the tribal communities while Importance value (IVs) of all the Gesneriaceae members were found ranging between 0.16-0.88. Boeica fulva and Rhynchotechum ellipticum has showed highest importance value (0.88 each) indicating their economic and cultural importance while the genera Lysionotus and Loxostigma are reported as ethnobotanical novelties.
... Although the earliest collections of gesneriads from Northeast India date back to the late 19th century, due to limited access to field sites, many areas had remained unexplored in the past century, resulting in a lack of recollections of gesneriads from this region. In the last decade, a revived interest in studies focused on plants from the family Gesneriaceae in India has resulted in updated generic concepts and new classifications (Sinha and Datta 2016;Möller et al. 2017;Roy 2017), the discovery of thirteen new gesneriad species Nampy 2015, 2020;Joe et al. 2016;Vadakkoot et al. 2018;Kanthraj et al. 2020;Taram and Borah 2020;Taram et al. 2020a;, and rediscoveries and range extensions of at least 17 species (Geethakumary et al. 2016;Alappatt 2020;Lahiri et al. 2020;Padal et al. 2020;Pandey et al. 2020;Taram et al. 2020b). ...
... While working on the floristic diversity of Eastern Himalayan state Arunachal Pradesh, India (Taram et al. 2018a, Taram et al. 2018b, Borah et al. 2019, Borah et al. 2020a, Borah et al. 2020b, Borah et al. 2020c) a remarkable species of Pseudobartsia was collected from Bomdila, West Kameng district at about 2500 m a.s.l. After a critical study including a comparison with its protologue and type specimens, it is identified as Pseudobartsia glandulosa, a little known, endangered small herb (Fig. 1). ...
While working on the floristic diversity of Eastern Himalayan state Arunachal Pradesh, India a remarkable species of Pseudobartsia was collected from Bomdila, West Kameng district at about 2500 m a.s.l. After a critical study including a comparison with its protologue and type specimens, it is identified as Pseudobartsia glandulosa, a little known, endangered small herb. The present collection is a rediscovery of this endangered species after the lapse of 179 years from India. Extended taxonomical description, color plates with the first available photographs are provided along with discussion on
habitat, phenology and conservation status.
... The plants are mostly found in tropical forests, preferring moist shady places near streams and river banks (Anderson & Middleton, 2013). The genus is also known to have ethnobotanical importance and is used by many tribes residing in Northeast India (Kayang, 2007;Ozah & Borah, 2018 (Anderson & Middleton, 2013;Sinha & Datta, 2016;Möller et al., 2017;Taram et al., 2020). ...
A new species of Rhynchotechum (Gesneriaceae), Rhynchotechum nirijuliense Taram & D.Borah, is described from Nirijuli of Papum Pare district in Arunachal Pradesh, Northeast India. The new species is compared to Rhynchotechum ellipticum and R. calycinum. A detailed description, colour photographs and notes on the distribution and ecology of the new species are provided.
Lectotypes are designated for four species epithets, including one second-step lectotypification, under the family Gesneriaceae Rich. & Juss., viz., Cyananthus umbrosa Griff., Didymocarpus griffithii Wight, Lysionotus pubescens C.B.Clarke and Petrocosmea parryorum C.E.C.Fisch., along with detailed notes on their typification.
