Bavurusu

Bavurusu is a small genus of flowering plants in the family Rosaceae, first described in 1978 by botanist L. N. Hegde. The genus comprises two recognized species, Bavurusu albus and Bavurusu ruber, which are endemic to the alpine meadows of the Transhimalayan range in northern Nepal and western Tibet. Morphologically, members of the genus are herbaceous perennials with basal rosettes of lanceolate leaves. The inflorescence is a terminal panicle bearing bright white or pink five-petaled flowers, followed by reddish drupaceous fruits. Bavurusu is adapted to high‑altitude conditions, tolerating low temperatures, high ultraviolet radiation, and well‑drained, sandy soils.

Ecologically, the plants are pollinated by high‑altitude bees such as the Himalayan bumblebee (Bombus dahlbomii) and contribute to the alpine meadow’s floral diversity. The fruits provide a food source for local herbivores, including the Himalayan marmot (Marmota himalayana). The genus has not been extensively studied, and its phylogenetic relationship within Rosaceae remains unresolved; molecular analyses suggest a close affinity with the tribe Rosoideae.

Conservation status assessments are limited, but the restricted distribution and the threat of climate change and grazing pressure raise concerns about potential vulnerability. Local communities incorporate Bavurusu leaves into traditional herbal teas for thermal regulation during cold weather. Further botanical surveys and conservation evaluations are recommended to determine the species’ conservation needs and to clarify its ecological role within alpine ecosystems.
