description

Tulipa altaica is a perennial , herbaceous plant that reaches heights of between 10 and 20 centimeters (less often up to 35 centimeters).

The egg-shaped onion has a diameter of 2 to 3.5 centimeters and is slightly elongated at the tip. The paper-like outer skin (onion cover) is brown and, when pressed down, is hairy or bald on the inside.

The stem axis is hairy protruding upwards. The three or four leaves are greyish green and ovate to lanceolate. They are variable in size, but do not protrude beyond the flower. They are between 0.6 and 3 centimeters (less often up to 5 centimeters) wide and bald or slightly hairy. The leaf margins are often wavy.

The single flowers are hermaphroditic and threefold. The six elongated or elongated-diamond-shaped, pointed to pointed tepals are between 2 and 3.5 inches long and 0.5 to 2 inches wide. They are yellow and tinged with greenish-purple or pink on the outside. The six stamens are 0.4 to 0.5 times as long as the tepals, glabrous and narrowed from the base. The pollen measures 38.4 to 40.3 × 53.7 to 67.2 micrometers. There are three apertures (germ openings) on the pollen grains . The exine is 1.9 micrometers thick. The stylus is very short.

After fertilization, broad ellipsoidal capsule fruits ripen , measuring 2.5 to 4 × 1.5 to 2 centimeters.

Tulipa altaica flowers in May and fruit in June and July. The number of chromosomes is 2n = 24, less often 48.

Occurrence

The main distribution area of Tulipa altaica is in the Altai Mountains. and broadcasts to the northwest of the Xinjiang Autonomous Region in the People's Republic of China and parts of Kazakhstan .

Tulipa altaica grows in thickets and on sunny slopes at altitudes between 1300 and 2600 meters.
