Abstract:

Pancratium donaldii (Amaryllidaceae), a rare and narrowly endemic plant, has been rediscovered after a gap of 92 years in the Mahadev hill ranges of Khatav Tahasil, located in the eastern part of Satara district, Maharashtra. Until now, the species was known only from its type localities in Panchgani and Satara. The new record, about 45 km from Satara and 97 km from the Panchgani Table Land, represents a significant extension of its known distribution. The Mahadev hill ranges form part of the north-western Deccan Plateau and are characterized by semi-arid conditions with lateritic soils. Here, P. donaldii was observed thriving in rocky crevices and shallow soil patches along open hill slopes exposed to intense sunlight. The surrounding vegetation is dominated by xerophytic herbs and shrubs, reflecting the region’s harsh, dry climate and limited rainfall. The rediscovered population was studied in detail, with a complete morphological description supported by high-resolution photographs and illustrations for easy identification. The species is distinguished by its striking large, fragrant white flowers, slender linear leaves, and bulbous base. Ecological observations suggest that P. donaldii has a very narrow habitat preference, surviving only in exposed, rocky terrain with minimal vegetation cover.This rediscovery highlights the urgent need for conservation action. Given its highly restricted range and habitat specificity, the species is vulnerable to habitat disturbance. Targeted field surveys across the Deccan Plateau are recommended, both to locate additional populations and to assess the conservation status of other rare or overlooked species in the region.
