Three new Viola species from Yunnan China

Professor Huang Su-Hua from the Department of Biology of Yunnan University described three new Viola species found in Yunnan province in an article published in the Acta Botanica Yunnanica (issue 4, 2003). The new species are:

Viola jizushanensis
This species is similar to V. rockiana, but the leaves are smaller with serried netted stripes on the back and the flowers are small.

Viola subdelavayi
This is similar to V. delavayi, but the leaves are narrow oval-triangular shaped with serrated margins. The flowers are light yellow.

Viola binchuanensis
This is similar to V. moupinensis (the wild violet with the second largest leaves I've ever seen; the largest being
V. magnifica, which I just saw this past Thursday), but the plant is smaller with small white flowers.

Very interesting - thanks very much for sharing, violet_blue!

Acta Botanica Yunnanica is available online, at the link below, but only numbers 1 and 2 for 2003, so far; and for them none of the links (eg. abstract) works - oh how frustrating! :)

RE: Three new Viola species from Yunnan China

Do any of the species Viola binchuanensis, V. moupinensis or
V. magnifica have leaves with purple veins, midrib, and petiole?

RE: Three new Viola species from Yunnan China

V. moupinensis and V. magnifica don't have purple veins, midrib or petiole.

As to V. binchuanensis, I have never seen it and Prof. Huang's description of it was all in Latin which I cannot read so sorry I don't know.

RE: Three new Viola species from Yunnan China

Dear violet_blue,
Thank you for your helpful reply. I will try to get Prof. Huang's paper and translate the Latin. I photographed a viola in two places in NW Yunnan which had large leaves, and the purple veins I described, with smallish mauve-purple flowers below the leaves (which may have been because it was later in the flowering season and the leaves had grown taller than when they first appear). I have not been able to identify it from the key.
