Consider the following statements about Rhynchostylis retusa (Foxtail orchid): 1. It is an epiphytic orchid. 2. The species is endemic to North-east India. 3. It is the State flower of Arunachal Pradesh and Assam. Which of the statements given above is/are correct?

Rhynchostylis retusa, commonly known as Foxtail orchid, is an epiphytic orchid that grows on tree trunks and branches in tropical forests, so statement 1 is correct. The species is NOT endemic to North-east India; it is widely distributed across South and Southeast Asia including India, Sri Lanka, Bangladesh, Myanmar, Thailand, Cambodia, Laos, Vietnam, Malaysia, Indonesia, and the Philippines, hence statement 2 is incorrect. It is the State flower of Assam (where it is called 'Kopou Phul') but NOT of Arunachal Pradesh, whose state flower is the Foxtail lily (Fritillaria) / Rhynchostylis is associated with Assam only — Arunachal Pradesh's state flower is the Foxtail orchid in some references but officially it is recognized only as Assam's state flower. Therefore statement 3 is incorrect. Only statement 1 is correct.
