New species and varieties of Meconopsis. 1.
At the end of 2019 two papers describing new species of Meconopsis were published, with some other taxonomic changes.
In the first one, M. georgei and M. castanea are shown to be distinct species. They were originally published separately, but latterly had been thought to be variants of a single species. They are compared with the related M. bijiangensis, and a new species, M. atrovinosa, is described.

New species and varieties of Meconopsis. 2.
In the second paper, Toshio Yoshida and Sun Hang revised Meconopsis section Forrestianae. It is thorough and detailed work; there are several name changes, and no less than three new species, M. aprica, M. purpurea and M. wengdaensis. You can see a photograph of M. purpurea on our Home page.
M. xiangchengensis becomes a subspecies of M. lancifolia, which also gains two new subspecies, subsp. daliensis and subsp. shikaensis. Finally, a new variety of M. yaoshanensis, var. luojiensis, is described.
The reference is Harvard Papers in Botany, Vol. 24, No. 2, 2019, pp. 379–421.
New species and varieties of Meconopsis. 3, 4 and 5.
The references at the end of the papers mentioned in ‘New species and varieties of Meconopsis’ 1 and 2 alerted us to three other papers – and another six newly described species.
They are all included in our Classification web page, and if you follow the notes they will take you to the references.
Two new species of yellow Meconopsis
Two new Meconopsis in the series Integrifoliae have been described. M. uniflora is a dwarf, high-alpine species, originally known as M. integrifolia var. uniflora and more recently included in M. pseudointegrifolia. Harvard Papers in Botany, Vol 24, No. 1, 2019, pp. 41-46.
Toshio Yoshida has also described a species from Sichuan as Meconopsis wanbaensis. This is the same as a plant discovered by Jens Nielsen in 2012 about 40 km away. It has been in cultivation since 2012 under names including M. aff. pseudointegrifolia and M. lijiangensis.
In the same paper a new variety of M. pulchella, var. melananthera, is also described. Harvard Papers in Botany, Vol 24, No. 1, 2019, pp. 31-39.
