Notes on phenology and habitat
Sonerila travancorica
was collected with flowers and fruits from January to April. This endemic species is found only in the Agasthyamala Biosphere reserve in the southern Western Ghats (
Fig. 1
).
Sonerila travancorica
occurs in shady terrestrial habitats, but occasionally is found on the base of tree trunks or rocks with a relatively thick mossy substratum. It grows along the margins of sholas and near streams, waterfalls or dam areas at elevations above
1200 m
. It is found in association with
Sonerila brunonis
Wight & Arn. (Melastomataceae)
,
Digitaria ciliaris
(Retz.) Koeler
,
Bambusa
Schreb.
sp. (both
Poaceae
),
Impatiens
L. sp. (
Balsaminaceae A.Rich.
), and certain mosses.
Provisional conservation status
This species is known from six locations in Agasthyamala Biosphere reserve in
Kerala
and
Tamil Nadu
. The estimated Extent of Occurrence (EOO) is ca
300 km
² and Area of Occupancy (AOO) is
12 km
². The authors surveyed three locations and found a total of 230 mature plants. Since these locations are inside a protected area, the risk of a decline due to anthropogenic activity is small. Based on the above data, the species is provisionally assessed here as Endangered (EN) B1ab(iii, iv, v), D (
IUCN 2019
).
