Siroi lily is the state flower of Manipur, but has unfortunately become a rare and endangered species in India.  In fact, in Manipur the flower is compared to a beautiful and modest girl. A postal stamp was issued by the Indian Postal Department to commemorate this flower. Frank Kingdon-Ward came to Manipur with his wife - Mackliniae for botanical research, in 1946. They set up base at Ukhrul in a building which they called "Cobweb cottage alias Bug bungalow" Frank made the exciting "discovery" of Siroi lily, and named it after his wife Jean Macklin.
