It differs in having denser hairs on the upper leaf surface which are much shorter, giving the leaf a rough appearance (not glossy); tepals which although pilose abaxially have shorter and more sparse hairs, and sparser and shorter hairs on the petioles and peduncles; it is also a smaller plant i.e. less than 30 cm (vs. up to 60 cm tall) and has shorter internodes i.e. less than 3 cm long on the erect stem (vs. up to 23 cm). It differs from <i>B. menglianensis</i> in having cauline leaves on the inflorescence (vs. absent), white ovaries with sparse red pilose hairs (vs. red or green ovaries which are glabrous), sparser and shorter white (vs. denser and longer red) pilose indumentum on the petioles and veins on the lower leaf surface, and leaves with an acuminate (vs. rounded to acute) apex. Type:— INDIA, Arunachal Pradesh, Siang district, Babuk, Kekar Monying, 15 February 2020, <i>M</i> <i>.</i> <i>Taram &amp; D.Borah 2094</i> (Holotype: ASSAM, Isotype: ARUN). Plant monoecious, perennial, rhizomatous, 15–30 cm tall. Stem erect when flowering, branched, 4–10 cm long, 5– 8 mm thick, internodes 0.3–3 cm long, longest on flowering stems. Stipule deciduous, slightly membranous, triangular 8–12 × 4–6 mm, sparsely pubescent, later glabrescent, greenish-white, margin entire, apex cuspidate, cusp <i>ca.</i> 3–4 mm long. Leaves 6–12 per plant. Petiole red, terete, 4–14 cm long, 3–5 mm thick, white pilose, ca. 0.2 mm long. Blade green, broadly ovate, 15–17 × 4–11 cm, strongly asymmetric, puberulous on both surfaces (adaxial surface hairs white, abaxial surface hairs pink, denser on veins); venation palmate, 6–7 veined; cordate at base, lobes overlapping slightly, margin irregularly serrulate, apex acuminate. Inflorescence axillary, 7–15.5 c [...]

The new species is easily distinguished from its allied species, P. leptanthum by its broad oblanceolate or broad elliptic, longer leaves, longer inflorescence, rachis stipitate glandular hairy, smaller peduncle, stipitate glandular hairy, pedicel stipitate glandular hairy and calyx stipitate glandular hairy, smaller flower, corolla tube broadly ovoid, shorter than limb, limb 1-lipped, smaller lobes, the entire abaxial surface and the base of adaxial surface densely stipitate glandular, smaller filaments, smaller style and smaller capsule.

Evaluation of ethnobotanical knowledge in Komkar-Adi Biocultural Landscape of Eastern Himalayan Region of India. Biodiversitas 21: 70-87. The present study was aimed to document the traditional ethnobotanical knowledge in Komkar-Adi Biocultural Landscape of Upper Siang District in Arunachal Pradesh (Eastern Himalaya), India. Data was collected from three villages of Geku circle, Upper Siang District between the year 2016-2019, covering more than 50% of the total households using semi-structured questionnaires, personal interviews, focused group discussions and transect walk with the core respondents. A total of 301 taxa falling in 203 genera and 85 families are recorded from the Komkar-Adi Biocultural Landscape (KABL), invariably used as food, medicine and cultural materials which is directly and indirectly linked with livelihood security, community survival, protection and preservation of the traditional culture and natur...

Thirty nine names are synonymized, after a detailed ecological study of live plants in the field and examination of herbarium specimens including types. Six new combinations with change in their status are proposed for six taxa.
