Scientists from the Jawaharlal Nehru Tropical Botanic Garden and Research Institute (JNTBGRI), Palode, person discovered a caller evergreen histrion taxon from the confederate Western Ghats of Kerala. The recently discovered taxon identified successful the riparian forests of the Shendurney Wildlife Sanctuary has been officially named, Humboldtia nairiana.
The species, belonging to the genus Humboldtia, has been named successful honour of G.M. Nair, a distinguished works biotechnologist and erstwhile Director of JNTBGRI, acknowledging his outstanding contributions to botanical probe and works conservation, and connected the juncture of his 75th commencement anniversary. The archetypal breakthrough for the find began successful 2010 during a floristic exploration on the Cheenikkala-Pandimotta wood way wrong the Shendurney Wildlife Sanctuary. JNTBGRI scientists Santhosh Kumar E.S., Sabu T. and Shareef S.M. collected an antithetic and taxonomically intriguing specimen.
To cautiously observe and safeguard the plant, a fewer steadfast seedlings were brought backmost and successfully established ex-situ wrong the JNTBGRI Arboretum. After a prolonged juvenile phase, the cultivated trees began flowering and fruiting successful 2022. This allowed the probe squad to behaviour a broad morphological assessment, which confirmed that its chiseled vegetative and reproductive characters acceptable it isolated arsenic a brand-new taxon to science.
Medium-sized tree
Humboldtia nairiana is a medium-sized evergreen histrion that grows betwixt 5 to 8 metres successful height. While it shares a adjacent affinity to Humboldtia ponmudiana, it possesses unchangeable and distinguishing features including a unsocial warty, airy brownish bark with a chiseled creamy-white blaze; angled, glabrous branchlets; distinctly shorter, sparsely hairy, isometric stipules and appendages; larger flowers with comparatively agelong pedicels, and produces elliptic-oblong fruits with a shorter beak.
The taxon is strictly endemic to Kerala and is presently known lone from the biodiversity-rich Agasthyamala Biosphere Reserve astatine an elevation of astir 300 meters. Alarmingly, tract surveys bespeak a fragile chaotic population. The full known situation spans an country of little than 2 sq.km. and comprises little than 10 mature trees. Based connected the IUCN Red List criteria, the researchers person categorised the taxon arsenic ‘data deficient’ to item the contiguous request for extended tract tracking and strict situation extortion to forestall it from sliding into extinction.
