The Japanese dog tooth ( Erythronium japonicum ) is a plant from the family of Liliaceae (Liliaceae).
features
The Japanese dog tooth is a perennial, herbaceous bulb plant that reaches heights of 16 to 20 centimeters. The onion measures 5 to 6 × approximately 1 centimeter. There are often several daughter onions at their base. The leaf blade measures 10 to 11 × 2.5 to 6.5 centimeters and is elliptical to broadly lanceolate and glabrous. Their base is wedge-shaped, the tip blunt, pointed or prickly. The petiole is 3 to 4 inches long. The flowers are solitary and are located on long flower stalks. The tepals measure 50 to 60 (rarely from 35) × 5 to 11 millimeters. At its base there is a three-toothed black mark on the top. The stamens are less than 1 millimeter wide and not broadened in the middle.
The flowering period extends from April to May.
The number of chromosomes is 2n = 24.
Occurrences and names
The Japanese dog tooth is found in northeast China, Korea, Japan and the southern Kuril Islands. The species grows in humid forests in the lowlands.
Its Chinese name means "pig tooth flower" ( Chinese 猪 牙 花 , pinyin zhu ya hua ). In Japan it is called katakuri , which either comes from the fact that the lily ( yuri ) looks like a leaning ( katamu ) basket ( kago ) - katakago yuri → katako yuri → katakuri - or because the leaves of the plant like the cotyledons as part ( kata ) look like a chestnut ( kuri ), which can also be found in the Japanese spelling of the plant as 片 栗 .
Systematics
The species was first described by Joseph Decaisne in 1854 .
use
In Japanese cuisine and for Japanese sweets , the washed-out powder of the crushed tuber was used as starch until it was largely replaced by the much cheaper potato starch , which then also took its name and is now sold in Japan as katakuriko ( katakuri flour).
The Japanese dog's tooth is rarely used as an ornamental plant for the edges of trees, rock gardens and dry lawns.
