Meconopsis autumnalis

Meconopsis autumnalis, the Nepalese autumn poppy, is a yellow-flowered Himalayan poppy belonging to series Robustae, and is endemic to the Ganesh Himal range of central Nepal, where it was discovered in 2008 on a research expedition from the University of Aberdeen. In addition to several morphological features, the species is characterised by its late flowering period (as reflected in the specific etymology), which has more than likely resulted in a barrier to gene flow and subsequent evolutionary divergence from the closely related and sympatric species Meconopsis paniculata. The leaves (laminae) are hairy, pinnatisect and 33–55 cm long and 8–16 cm wide, with a petiole 11–25 cm (rarely 31 cm) long. The flowers are pale yellow with four (rarely six) petals each 4.3–5.6 cm long by 4.1–5.5 cm wide. Specimens of M. autumnalis had twice previously been collected, by famous plant hunter J. D. A. Stainton on his 1962 expedition with S. A. Bowes Lyon to central Nepal, and on the Flora of Gan......read more on Wikipedia.
