- D3 only
Show answer
Answer: (B) 1 and 3
The correct answer is 1 and 3.
Key Points
- Statement 1 is correct. Rhynchostylis retusa is a vigorous epiphytic orchid. Its long, drooping inflorescence looks like a brush or a tail, which is why it is commonly called the Foxtail Orchid. As an epiphyte, it grows on other plants only for physical support, and absorbs moisture and nutrients from the air and rain.
- Statement 2 is incorrect. The species is not restricted to North-east India. It has a vast distribution across South and Southeast Asia, including Sri Lanka, Thailand, Malaysia, Indonesia, Vietnam and the Philippines. Within India, it is also found in the Western Ghats and the Himalayan foothills.
- Statement 3 is correct. The Foxtail Orchid has deep cultural and symbolic value in North-east India. It is officially the State flower of both Arunachal Pradesh and Assam.
Additional Information
- In Assam, it is known as Kopou Phul and is an integral part of the Rongali Bihu festival, where female dancers wear the blossoms in their hair.
- The plant produces cylindrical, dense flowers, usually white with pink or purple spots, blooming in the pre-monsoon season.
- Conservation: Because of its popularity in the horticultural trade and loss of habitat, it is listed under Appendix II of CITES, which regulates international trade and helps ensure its survival in the wild.
- Medicinal uses: Various traditional systems use extracts of the plant to treat ailments such as asthma, skin diseases and joint pains.
Rhynchostylis retusa is the state flower of both Arunachal Pradesh and Assam, making it significant for Northeast India's cultural identity.
The species has wide distribution across South and Southeast Asia, not just Northeast India, which is a common misconception UPSC exploits.
UPSC tests orchid knowledge because many species are CITES-listed and face conservation challenges due to illegal trade.

Listed under CITES Appendix II for trade regulation
What is Foxtail Orchid
Rhynchostylis retusa is a vigorous epiphytic orchid named for its long, drooping flower clusters that resemble a fox's tail or brush. As an epiphyte, it grows on other plants for physical support while absorbing moisture and nutrients directly from air and rain.
Key Characteristics
Aspect | Details |
|---|---|
Growth Type | Epiphytic - grows on other plants for support |
Flower Structure | Cylindrical, dense clusters; white with pink/purple spots |
Blooming Season | Pre-monsoon period |
Common Name Origin | Drooping inflorescence resembles a foxtail or brush |
Local Name (Assam) | Kopou Phul |
Distribution Pattern
Region | Countries/Areas |
|---|---|
South Asia | India (Northeast, Western Ghats, Himalayan foothills), Sri Lanka |
Southeast Asia | Thailand, Malaysia, Indonesia, Vietnam, Philippines |
Within India | Arunachal Pradesh, Assam + Western Ghats + Himalayan foothills |
Cultural & Official Status
Official State flower of Arunachal Pradesh and Assam - rare for one species to represent two states
Integral part of Rongali Bihu festival in Assam where dancers wear blossoms in hair
Deep cultural symbolism in Northeast India beyond just official recognition
Traditional medicinal uses for asthma, skin diseases, and joint pains
Question Analysis
Statement 2 was the trap - while the orchid has deep cultural significance in Northeast India and serves as state flower for two northeastern states, it is not geographically endemic to the region. Its distribution spans multiple countries across South and Southeast Asia.
Endemic vs culturally significant: Species can have deep cultural ties to a region without being geographically restricted to it
State flower ≠ endemic species: Official state symbols may represent culturally important species found in multiple regions
Epiphytic vs parasitic: Epiphytes use other plants for support only, not for nutrients like parasites do
CITES Appendix II: Regulates trade but doesn't mean critically endangered - allows controlled commercial trade
Epiphytic Plants
Environment epiphytic
Epiphytic Plants: Adaptations & Ecological Role
Plants that grow on other plants for physical support only
Absorb nutrients from air, rain, and organic debris
Not parasitic - don't harm the host plant
Common in tropical forests with high humidity
Definition & Mechanism
Epiphytes are plants that grow on other plants (called hosts) purely for physical support and better access to sunlight. Unlike parasites, they don't extract nutrients from their host - instead they absorb moisture and nutrients directly from air, rainwater, and accumulated organic matter.
Epiphyte vs Other Plant Types
Type | Relationship with Host | Nutrient Source | Examples |
|---|---|---|---|
Epiphyte | Uses for support only | Air, rain, debris | Orchids, bromeliads, ferns |
Parasite | Harms host, extracts nutrients | Host plant tissues | Mistletoe, dodder |
Terrestrial | No host needed | Soil through roots | Most trees, shrubs |
Climber | Uses for support, roots in soil | Soil + some air moisture | Vines, ivy |
Ecological Adaptations
Aerial roots to absorb moisture from humid air and collect organic debris
Thick, waxy leaves to store water and prevent excessive water loss
Specialized scales on leaves to capture nutrients from rainwater
Often found in forest canopies where they access more sunlight than forest floor
Common Epiphytic Families
Orchidaceae - largest family of epiphytes including Foxtail orchid
Bromeliaceae - includes air plants and some pineapple relatives
Araceae - includes many tropical houseplants
Polypodiaceae - various fern species in tropical forests
State Flowers of India
Art And Culture State flower Arunachal Pradesh Assam
State Flowers of India: Cultural & Ecological Significance
Each Indian state has an official state flower representing cultural heritage
Rhynchostylis retusa is state flower of both Arunachal Pradesh and Assam
State flowers often reflect local biodiversity and cultural practices
Many state flowers are economically or medicinally important species
Cultural Significance
State flowers represent the cultural identity and natural heritage of Indian states. They are often species deeply integrated into local festivals, traditions, and daily life rather than just botanically significant plants.
Notable State Flowers
State | State Flower | Scientific Name | Cultural Context |
|---|---|---|---|
Arunachal Pradesh | Foxtail Orchid | Rhynchostylis retusa | Symbol of natural beauty |
Assam | Foxtail Orchid (Kopou Phul) | Rhynchostylis retusa | Used in Rongali Bihu festival |

Festival connections: Many state flowers have specific festival associations (Kopou Phul in Bihu)
CITES Conservation Framework
Environment
CITES: International Wildlife Trade Regulation
Convention on International Trade in Endangered Species - regulates wildlife trade
Three appendices with different levels of trade restrictions
Appendix II allows controlled trade with permits
Covers plants and animals threatened by international commerce
CITES Framework
CITES (Convention on International Trade in Endangered Species of Wild Fauna and Flora) is an international agreement regulating wildlife trade to ensure species survival. It doesn't ban trade completely but controls it through a permit system based on conservation status.
CITES Appendix Classification
Appendix | Conservation Status | Trade Restriction | Examples |
|---|---|---|---|
Appendix I | Critically endangered | Commercial trade banned | Tigers, elephants, great apes |
Appendix II | Vulnerable to over-exploitation | Controlled trade with permits | Foxtail orchid, many parrots |
Appendix III | Protected in specific countries | Country-specific controls | Two-toed sloth, walrus |
Appendix II Significance
Largest category - includes species that could become endangered without trade controls
Permits required for international commercial trade from exporting country
Monitoring mechanism - tracks trade volumes to prevent over-exploitation
Most orchids fall under Appendix II due to horticultural demand
India & CITES
India is a CITES signatory since 1976 - legally binding commitment
Wildlife Protection Act 1972 implements CITES provisions domestically
Directorate of Wildlife Protection serves as CITES Management Authority
Many endemic Indian species listed across all three appendices
Appendix II ≠ critically endangered: Allows controlled trade, stricter than Appendix III but less than Appendix I
CITES covers plants too: Not just animals - many commercially valuable plants like orchids included
Permits vs bans: Appendix II requires permits, doesn't ban trade completely like Appendix I
Conservation vs trade regulation: CITES regulates international trade, doesn't directly manage habitat conservation
