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

Rhynchostylis retusa (Foxtail Orchid) is indeed an epiphytic orchid that grows on tree trunks — Statement 1 is correct. Statement 2 is incorrect because the species is not endemic to North-East India; it is found across South and South-East Asia including Sri Lanka, Bangladesh, Myanmar, Thailand, Indonesia, Philippines, and Vietnam. Statement 3 is incorrect because while Rhynchostylis retusa (locally called 'Kopou Phool') is the State flower of Assam, it is NOT the state flower of Arunachal Pradesh — Arunachal Pradesh's state flower is Rhynchostylis retusa? Actually it is the state flower of Assam only; Arunachal Pradesh's state flower is the Lady Slipper Orchid (Paphiopedilum). Hence only Statement 1 is correct.
