Tulipa akamasica is a plant species from the genus Tulipa in the lily family (Liliaceae).

Features
Tulipa akamasica is growing upright. The species reaches heights of 9 to 25, rarely up to 30 centimeters. The onions are spherical-elongated and measure 17 to 20, rarely up to 25 × 12 to 18 millimetres. Extensions are not formed. The outer onion skins are dark brown to blackish brown and unhaired, the inner ones are lighter brown with a ring of hair around the base plate and a shaggy strip on the neck. The hair is brownish and usually 2 to 3 millimeters long. The stem is erect, with short, fluffy whitish hair, uniflorous and measures 2 to 2.5 millimeters in diameter at the thickest point. The lower part is green, the upper half has a reddish-brown tint. The underground part of the stem is about 6 centimeters long and whitish. The three to seven foliage leaves are initially channel-shaped and become flatter with increasing age. They are green, slightly blue-green on the underside and have neither hair nor eyelashes. The lower leaves measure 130 to 305 × 4 to 12 (rarely from 3 and up to 16) millimeters, the upper ones remain shorter and are usually 2 to 3 millimeters wide. They are pointed up to pointed and reach approximately the height of the flower.

The individual flower has a diameter of seldom from 60, usually 70 to 75 millimeters, is hairless and opens to a loose star. The bud is straight. The petals are bright red. On its inside, there is a basal black, usually very irregularly toothed, occupying about 10 to 20 percent of the leaf length. This is followed by an approximately 1.5 millimeter wide band, which is yellow on the inside and red on the outside. The lower third of the coat leaves is often greenish at flowering time. The limbs of the flower shell differ slightly. The outer coat leaves are inverted lobe-shaped, narrowed at the base, 31 to 41 × 10 to 15 millimeters in size and pointed or sometimes blunt. The inner coat leaves are perverted, narrowed at the base, 33 to 38 (rare to 42) × 17 to 19 (rare from 13 and up to 20) millimeters in size and dull to more or less pointed. The stamens are longer than the fruit knot and uneven. The dust filaments are 6 to 6.5 millimetres long and purple-like or whitish on the base. Their base is hairy and widened. The dust bags are 3.5 to 4 millimeters long and purple colored for flowering, later they turn brown and often reach a length of 8 to 10 millimeters. The pollen is yellow. The fruit knot is 8 to 3.5 millimetres in size, almost sedentary, hairless and yellow. The three scars are seated and yellow-white.

The species blooms in March and April and fruits in May.

Tulipa akamasica is diploid, its chromosome number is 2n = 2x = 24.
