New Impatiens – Discovery of New Impatiens from India.
All Impatiens, including the newly discovered ones have beautiful bright coloured flowers, make them potential horticultural plants. Most of the terrestrial species can grow well in gardens. The only variation we observed is reducing the vigour of the flower. Several hybrids are grown in gardens. Majority of these are facing threat because of the road widening, deforestation and other developmental activities may lead to the loss of its natural habitat.
All papers were published in International journals- Phytotaxa and Webbia.
Impatiens Arunachalensis was discovered from Upper Siang District along the way Yingkiong to Pasighat. The plant possesses slender stem and 1-3 flowered inflorescence having pale purple colored flower with yellow and dark patches in the mouth and a long hooked spur is the identification feature.
The number of the individuals in the population is decreasing due to the widening of the road and other developmental activities. A few individuals have been noticed throughout the geographical range, hence reported as Critically Endangered.
