Discovery and Naming
- Strobilanthes riteshii was discovered by Indian botanists during floristic surveys in the Western Ghats.
- The species is named “riteshii” in honour of Ritesh, acknowledging contributions to botanical research and conservation.
- Such discoveries indicate that new plant species are still being found in India, especially in ecologically sensitive regions.
Geographical Distribution
- Endemic to India
- Found exclusively in the Western Ghats
- Grows in:
- Moist deciduous forests
- Semi-evergreen forest regions
- Shaded forest floors at specific elevations
📌 Endemism makes the species highly vulnerable to habitat disturbance.
Morphological Features
- Growth form: Herbaceous flowering plant
- Leaves: Opposite arrangement, ovate to elliptic, with prominent veins
- Flowers:
- Attractive bluish-purple or violet colour
- Tubular shape (typical of Strobilanthes genus)
- Flowering pattern:
- Some species of Strobilanthes are plietesial (flower once in many years), though further study is ongoing for S. riteshii
Ecological Importance
- Contributes to understorey vegetation of forests
- Supports:
- Pollinators like insects and butterflies
- Forest ecosystem stability
- Acts as an indicator species for healthy forest habitats
Conservation Status
- Not yet assessed by IUCN Red List
- Faces threats such as:
- Habitat loss
- Deforestation
- Climate change
- Human encroachment
🔴 Being a narrowly endemic species, it requires urgent conservation attention.
