Iris qinghainica is a beardless iris in the genus Iris, in the subgenus Limniris and in the Tenuifoliae series of the species. It is a rhizomatous herbaceous perennial, from China. It has grey green leaves, a very short stem and 1–2 blue or violet flowers.

Description

Iris qinghainica has a knobbly rhizome. On top of the rhizome are maroon-brown, fibrous (or straw-like), remnants (of last seasons leaves), as sheaths (of the new leaves).[2][3]

It has linear, narrow, greyish green leaves, that are between {{convert|5|-|25|cm|0|abbr=on}} long and between 2–3 mm wide. They have no obvious veining and end in a sharp point (acuminate).[2][3]

It has a very short flower stem, that often does not emerge from the ground.[2]

Overall, (stem and flower) the flower can reach up to {{convert|10|cm|0|abbr=on}} long.[2]

It has 3 green, lanceolate, between {{convert|6|-|10|cm|0|abbr=on}} long and between 0.6–1.8 cm wide, spathes (leaves of the flower bud).[2][3]

The stems hold between 1 and 2, terminal (top of stem) flowers, blooming between June and July.[2][3]

The flowers are {{convert|4.5|-|5|cm|0|abbr=on}} in diameter, and are in shades of blue or violet.[2][3][2]

It has two pairs of petals, three large sepals (outer petals), known as the 'falls' and 3 inner, smaller petals (or tepals), known as the 'standards'.[3] The falls are narrowly oblanceolate (top wider than the bottom), {{convert|3|-|3.5|cm|0|abbr=on}} long and 5 – 8 mm wide.[2] They have a small white signal patch.

The standards are also narrowly oblanceolate, but much smaller, only 3 cm long and 4 mm wide.[2]

It has a filiform (thread-like) {{convert|3|-|6|cm|0|abbr=on}} long, perianth tube.[2][3]

Also, 1.8 – 2 cm long stamens, 1.5 cm long ovary and triangular-like, style branches that are 2.5 cm long and 3 mm wide.[2][3] They are the same shade of colour as the petals.

After the iris has flowered, it produces a seed capsule (not described) between June and August.[2][3]

Taxonomy

It is written as 青海鸢尾 in Chinese script and known as qing hai yuan wei in Pinyin Chinese.[4][5][6][7]

It has the common name of 'Qinghai Iris'.[7][8][9]

The Latin specific epithet qinghainica refers to the Chinese provinces of Qinghai, in the northwest of the country of China.

It was published by and described by Yu Tang Zhao in Acta Phytotaxonomica Sinica (of Beijing) Vol.18, Issue 1 page 55 in 1980.[10][11]

Iris qinghainica is endemic to China, in the Chinese provinces of Gansu and Qinghai.[4][5][2][6][9]

It is found in grasslands and meadows, on mountain slopes, and on loess hills.[4][5]

It is in temperate habitats, at altitudes of between 2500–3100 m above sea level.[4][5][6][9]
