Four new species of Microchirita (Gesneriaceae) from Thailand

Abstract

Four new species of Microchirita (C. B. Clarke) Yin Z. Wang are here described: M. huppatatensis C. Puglisi and M. personata C. Puglisi, from Uthai Thani province, and M. hemratii C. Puglisi and M. lilacina C. Puglisi, from Tak province. Proposed conservation assessments are given for all species.

Eight new species of Microchirita (Gesneriaceae: Didymocarpoideae) from Thailand

“…Puglisi & Middleton (2017) revised the genus for Thailand, recognising 29 species, by far the highest concentration of species for a country across the range of the genus. Many of those 29 species were described only in recent years (Middleton & Triboun, 2013;Puglisi et al, 2016;Puglisi & Middleton, 2017), mostly based on collections made only shortly before. As new collections of Microchirita are made in areas previously insufficiently collected or not collected at all, it is perhaps unsurprising that more new species have come to light.…”

Microchirita minor (Gesneriaceae), a new species from north-western Vietnam

“…The genus currently comprises 39 species and six varieties (POWO 2022), including some species published in recent years (e.g. Puglisi et al 2016;Puglisi and Middleton 2017;Rafidah 2019). The genus Microchirita grows exclusively in limestone karst habitats of tropical Asia, of which, Thailand is considered to be the centre of diversity of Microchirita with 29 species recorded (Puglisi and Middleton 2017), followed by Indonesia, Cambodia, China, India, Laos, Myanmar and Vietnam (Puglisi and Middleton 2017;Rafidah 2017;Middleton 2018;Vu 2018;Wei 2018;Fu et al 2022;Wei et al 2022;Wen et al 2022).…”
