DANCING BUTTERFLIES OF THE EAST HIMALAYAS – NEW MECONOPSIS SPECIES FROM EAST BHUTAN, ARUNACHAL PRADESH AND SOUTH TIBET The Journal of Botanic Garden Horticulture, No. 14- Toshio Yoshida, Rinchen Yangzom & David Long (2017):
Abstract: The region from eastern Bhutan to Arunachal Pradesh of India and the adjacent south-eastern Tibet and northern Myanmar seems to be one of the last frontiers not only for Meconopsis hunting but also for other botanical exploration. Although there remain political difficulties for foreigners to approach the unsettled border between India and China, including the famous Tsari valley with its prominently rich flora, which was visited by Frank Ludlow, George Sherriff, Frank Kingdon-Ward and a few other plant hunters before 1950, some botanical and horticultural treasures in this region have gradually been revealed to recent travellers. As a result of examining the photographs taken by these travellers and our own botanical field research in eastern Bhutan in 2014, accompanied by subsequent herbarium studies, two species new to science are described. The first, from eastern Bhutan and adjacent Arunachal Pradesh and Tibet, has long been cultivated under the names M. grandis or M. grandis GS600, and has recently been described as M. grandis subsp. orientalis (Grey-Wilson, 2010). It is the national flower of Bhutan. However, the type of M. grandis from Sikkim belongs to a species quite distinct from the eastern populations and the latter is now described as a new species, Meconopsis gakyidiana. The second novelty, Meconopsis merakensis, is newly described from eastern Bhutan and adjacent Arunachal Pradesh. In the past this species was confused with the closely allied M. prainiana. The two species are isolated geographically, M. prainiana being found only much further to the north-east, in south-eastern Tibet, including the Tsari valley. The title of this article is based on a comparison made by Frank Kingdon-Ward of Meconopsis flowers with butterflies in Tibet (see below).
Key to Meconopsis gakyidiana and related species:
1a. Plant often forming a loose tuft with short or long rhizomes, taller in stature (to 120cm tall), with long stems; stem leaves more or less regularly alternate along long stems; lamina wider, with betony-like serration (remotely and regularly toothed with obliquely wedge-shaped sinus); bracts and upper leaves half clasping; fruit capsules shorter and thicker, to 5cm long, glabrescent or densely hairy …. 2

M. grandis
Key to Meconopsis prainiana and M. merakensis and their varieties:
1a. Fruit capsules ellipsoid, 1.5–2.5cm long; flowers usually half-nodding, widely opened and dish-shaped during fine weather; stems quite densely covered with patent spiny hairs ……….. 2 (M. prainiana)
2a. Petals pale blue to purple ……. M. prainiana var. prainiana (China (Xizang [south-east Tibet]): Temo La, Sang La, Nyima La, Nam La, Pab Ri in Tsela Dzong, Mira in Nyang Chu region, Shoga Dzong in Kongbo, Tsari Sama and Chiniung La in Langong, Bimbi La and Chikchar in Tsari)
2b. Petals pale yellow ………………. M. prainiana var. lutea (China (Xizang [south-east Tibet]): Shagam La on the south of Tsari, Mira La in Nyang Chu region)
1b. Fruit capsules sub-cylindrical, 3–3.7cm long; flowers usually deeply nodding, bowlshaped; stems less densely covered with spiny hairs …… 3 (M. merakensis)
3a. Petals bluish or purplish; plant usually growing larger, tip of elongate rachis often gradually narrowed and curved ……….. M. merakensis var. merakensis (East Bhutan: Merak and Sakten regions of Tashigang district. 3,800– 4,500m in elevation)
3b. Petals white or yellow; plant usually growing smaller, tip of rachis rarely curved ……. M. merakensis var. albolutea (India, Western Arunachal Pradesh, region around Orka La and Bhangajang, Milakatong La in Tawang district, Mago district; eastern Bhutan, Sakten region of Tashigang district; 3,800 –4,500m in elevation)

Meconopsis autumnalis and M. manasluensis (Papaveraceae), two new species of Himalayan poppy endemic to central Nepal with sympatric congeners by PAUL A. EGAN- Phytotaxa 20: 47–56 (2011)
Abstract– Two new species from Nepal, Meconopsis autumnalis and M. manasluensis, are described and illustrated with notes on diagnostic characters used to distinguish them from allied species. Sympatric speciation and the mechanisms to reproductively isolate the new species are discussed. In M. autumnalis, reproductive isolation from the widespread M. paniculata is the result of a shift in flowering phenology, whereas possible mechanisms preventing cross-fertilisation between M. manasluensis and the sympatric species M. pinnatifolia remain unclear.

I have updated eFI (efloraofindia) page on Meconopsis (Pl. click).
Attempts have been made to incorporate most of the species available in India & nearby areas with details & keys directly or through links as far as possible. It’s quite possible that there may be some discrepancy in the accepted names & synonyms taken from other links.
Species discussed so far in efloraofindia are given at the bottom of the page in the form of links against Subpages. On clicking them one can see all the details.
If someone can provide complete list of Indian species with source references it will be wonderful.
I have added list of Indian species based on Flora of India.
Thanks, … The species at other links match well with this list.
