in Gole, Page et Sardesai, 2026.

Abstract
A new species of Elaeocarpus is described from the Kodaikanal region of Pulney Hills, India; it is morphologically allied to E. variabilis in having anther tips without setae or tuft of hairs and 3-locular pyrenes. It differs from the latter in having ovate, light-green sepals, and ellipsoid fruits enclosing ellipsoid pyrenes. Molecular phylogenetic analyses based on ITS and trnL–F regions revealed that Elaeocarpus pulneyensis is distinct from E. variabilis and support the novelty of the taxon.

Elaeocarpus  pulneyensis can be distinguished from the majority of species of Elaeocarpus from South India and Sri Lanka in having anther tips without setae or tuft of hairs. It is morphologically most similar to Elaeocarpus variabilis, the only other species which exhibits anther tips without setae or tuft of hairs and 3-locular pyrenes. Elaeocarpus pulnyensis can be distinguished from E.variabilis based on light green sepals (vs green or reddish brown), ellipsoid fruits (vs obovoid), pyrenes which are rounded at both base and apex (vs pyrenes which are tapering towards the base and rounded towards the apex), and a pyrene circumference at widest point of 6.3–6.7 cm (vs 4.8–5.4 cm).

Etymology. The specific epithet pulneyensis is derived from the type locality, Pulney Hills, situated in Kodaikanal, Tamil Nadu, peninsular India.

Abstract
Based on an ongoing taxonomic study on the genus Elaeocarpus, a new endemic Elaeocarpus speciesElaeocarpus mahamayensis, is described and illustrated from the Knuckles Mountain Range in Matale District (Sri Lanka). The new species had been already noticed by Zmarzty in 2001; during the revision of Elaeocarpus sect. Elaeocarpus in Southern India and Sri Lanka, she referred a herbarium specimen of this plant as “Elaeocarpus sp. B”. The stone of Elaeocarpus mahamayensis is similar to that of E. amoenus, E. coriaceus, E. montanus and E. taprobanicus, but their leaf characters differ. With this new addition, the number of Elaeocarpus species occurring in Sri Lanka is elevated to ten. The conservation status of E. mahamayensis based on the IUCN Red Data category guidelines is determined as Critically Endangered.
