Iris dolichosiphon subsp. dolichosiphon
Iris dolichosiphon is a species in the genus Iris, it is also in the subgenus of Iris and in the Pseudoregelia section. It is a rhizomatous perennial, from China and Bhutan. It has long, thin dark green leaves, very short stem, and dark blue, purple, or violet flowers. That are mottled with white. It has thick white/orange beards. It has one subspecies, Iris dolichosiphon subsp. orientalis, from China, India and Burma. It has similar flowers. They are cultivated as ornamental plants in temperate regions
It has very short rhizomes, about 1 cm in diameter. They form dense clumps of plants, along the ground. Beneath the rhizome, are secondary roots that grow deep into the ground.
It has basal leaves can grow up to between 3–54 cm (1–21 in) long and between 0.2 and 1.4 cm wide. The leaves are around 23 cm (9 in) long at flowering time. They then extend after the blooming period is over, up to 54 cm (21 in) when the plant fruits. They grow 10 days before the plant flowers. They are dark green with waxy surfaces, linear, and gradually tapered to an acute apex (or point).
It has a very short stem, almost at ground level.
The stem has 3 or 4, membranous, spathes or bracts (leaves of the flower bud). They dry after flowering.
The stems hold 1 terminal (top of stem) flowers, blooming between April and June. The flowers can last for up to two days.
The flowers are 3–8.5 cm (1–3 in) in diameter, come in shades of blue, from dark blue, purple, to violet. They are mottled, or blotched, with white, or greenish-white.
The flowers are similar in form to Iris narcissiflora flowers, (another Pseudoregelia iris).
It has 2 pairs of petals, 3 large sepals (outer petals), known as the 'falls' and 3 inner, smaller petals (or tepals), known as the 'standards'. The falls are oblong, or spatulate (spoon like), 2.3–4.3 cm (1–2 in) long and 0.8 - 1.8 cm wide. They have a dense beard of clavate (club-shaped) hairs, that are orange tipped, at the junction of haft (bend on the petal) and blade (widest part of the petal). The deflexed (bent downwards) and spreading (horizontally) standards are 2–3.6 cm (1–1 in) long and 0.5 - 1.5 cm wide. They have brown and curled over margins.
