Vaccinium paucicrenatum Sleumer has been re-collected from three different districts of Arunachal Pradesh approximately after 91 years subsequent to I.H. Burkill’s collection (no. 36976, K) from Ripsing of outer Abor Hills (presently a part of East and West Siang districts nearby Pashighat area) of Arunachal Pradesh on 8 March, 1912.   Due to poor description by the earlier workers, the present paper provides amplified description based on field and herbarium data including leaf anatomy (leaf stomata and vein-islets), detailed extended distribution, live and herbarium images and distribution map for easy identification in the field.

This is the first description of the Bangru language spoken in a remote corner of Kurung Kumey district, Arunachal Pradesh, Northeast India. On the basis of our data and analysis, we identify Bangru as a Tibeto-Burman language with as its closest genetic relatives Miji and Hruso, spoken further to the southwest in East and West Kameng districts. Based on these preliminary data and their analysis, Bangru is described as having 18 distinctive consonants, seven distinctive simple vowels and three distinctive diphthong vowels. The basic syllable structure is Ci(G)V(Cf). Bangru is furthermore characterised by the retention of Proto-Tibeto-Burman prefixes as reduced syllables. This paper also provides additional evidence for the validity of Shafer’s ‘Hruso’, with Hruso itself as its most aberrant member.

A thin linear belt of Permian Lower Gondwana rocks occur in the Eastern Himalayas from Arunachal Pradesh to Sikkim. The Lower Gondwana Group of rocks consists of shale, siltstone, sandstone, carbonaceous shale and coaly matter and is sandwiched between Miri Group and Siwalik Group of rocks. Heavy mineral composition of sandstones is extensively used in the provenance studies as they are the surviving remnants of the rather abundant but unstable mafic components of the source rock. The sandstones of Lower Gondwana Group bear the heavy mineral assemblage of chlorite, biotite, zircon, ilmenite, epidote, garnet, amphibole, chloritoid, brown tourmaline, magnetite, staurolite, rutile, and opaques which is indicative of a provenance of metamorphic rocks with input of igneous rocks. Provenance sensitive mineral index ratios were also calculated to see the variation in the ratio of two or more stable minerals with the same characteristics.

Abstract. Paul A, Dutta PK, Khan ML, Das AK. 2019. Rhododendrons: A major resource of fuelwood in high altitude region of Arunachal Himalaya, India. Biodiversitas 20: 2628-2635. This study highlights rhododendrons consumption for fuelwood in Tawang district of Arunachal Pradesh. Rhododendron spp. contributed the highest (60% and 58%), Quercus spp. (33% and 40%) while Alnus species (7% and 2%) of the total fuelwood consumption in villages between 1800-2100 m and 2100-2400 m altitude, respectively. Consumption was recorded highest (3.45 kg/capita/day) in villages between 2100-2400 m than 1800-2100 m altitude (3.24 kg/capita/day). Fuelwood consumption was not significantly varied with altitudes (U = 364, p = 0.864). However, it was significantly different among species at altitude 1800-2100 m (F = 6.205, p < 0.05) and 2100-2400 m (χ2 = 31.319, p < 0.001). Irrespective of altitude, consumption was significantly different among the species (χ2 = 41.289, p < 0.001). Rhododendron arboreum and Rhododendron thomsonii with a mean rank of 47.35 and 49.88, respectively, were the most used fuelwood, followed by Quercus griffithii (33.08), Quercus sp. (26.04) and Alnus sp. (8.65). The remote villages, mostly use fuelwood for boiling, cooking and space heating. Intensive consumption pressure will lead to habitat degradation and mount fuelwood crisis in coming years. The present pilot study could be a basis to develop suitable conservation and management of energy resources, particularly the rhododendrons.

Rhynchotechum alternifolium C.B.Clarke, a Gesneriaceae plant taxon earlier known from India and Myanmar, is reported here as an extended distribution to Bhutan. In India, earlier it was reported from Arunachal Pradesh, Assam, Manipur and Nagaland. The last observation of this taxon was in 1962 from Myanmar. During recent field exploration (2015), it is once again reported from Nagaland. Based on herbaria records, it is also recorded from Sikkim Himalaya. Brief taxonomic description along with photographic illustration and distribution map of the taxon is provided. Further investigation is required in the eastern Himalaya and North-eastern region of India to ascertain its present population status as well as IUCN status for conservation point of view.INTERNATIONAL JOURNAL OF ENVIRONMENTVolume-6, Issue-2, Mar-May 2017, Page: 1-8

Comolia abaetensis, an endemic new species from the Abaeté and Itapuã sand dunes, Bahia, Brazil, is described and illustrated. Additionally, field images and a geographic distribution map of the new species are provided, together with morphological and leaf anatomy comparisons among the most similar congeners, and a dichotomous key to the species that occur in Brazil. Comolia abaetensis is morphologically similar to C. ovalifolia, but differs from the latter by the following combination of characteristics: glabrous (rarely with sparse trichomes)internodes and hirsute nodes, glabrous leaf blades or rarely with sparse eglandular trichomes, abaxial surface predominantly red with green nuances, glabrous pedicels, cupuliform hypanthium, and filaments of the antesepalous stamens that are 5–6 mm long. Specimens of C. abaetensis have been confused with and/or tentatively determined as C. berberifolia. However, these two species are readily distinguished by the size of the leaves, the length of the trichomes and filaments, and the color of the abaxial foliar surfaces. Comparisons between the leaf anatomy ofC. abaetensis and C. ovalifolia are provided and the occurrence of emergences and hydathodes are here reported for the genus for the first time. Finally, we informally recommend a conservation status of Critically Endangered [CR B1ab (iv) + 2ab (iv)] for C. abaetensis.
