Appearance and foliage leaf
The Siebolds primrose is a perennial herbaceous plant with heights of 12 to 25 (to 30) centimeters.
The leaves , standing together in a basal rosette , consist of a petiole and a leaf blade. The densely hairy petiole has a length of 4 to 12 (to 18) centimeters. The multicellular and grayish hair -bearing lamina is provided with a length of 4 to 10 centimeters and a width of (2) 3 to 7 centimeters ovoid -länglich to elongate and at Spreitengrund heart-shaped or rounded up to almost rarely truncated. The leaf margin is notched- lobed and the tip is rounded. The lobes are serrated and serrated.
Inflorescence and flower
The flowering time is in May. The 12 to 25 (up to 30) centimeter long inflorescence stem is hairy. The umbellate inflorescence contains 5 to 15 flowers and with a length of 4 to 10 millimeters linear-lanceolate bracts . The slightly hairy or balding flower stalks are 0.4 to 3 inches long.
The hermaphrodite flowers are heterostyle , radial symmetry and five-fold with a double flower envelope . The five 6 to 8 millimeters long sepals , which lengthen by up to 1.5 centimeters during fruit formation, are fused together in a bell-shaped manner from halfway or above. The lanceolate to ovate-lanceolate, hairy or hairless sepal teeth are more or less spread out. The five pink to lavender-purple and rarely white petals are fused to form a 0.9 to 1.3 centimeter long crown tube. The 1 to 2 (to 3) centimeter wide coronet has obovate , double-split petal lobes at the top. The Heterostylie the flowers shown by the fact that either the stamens spring slightly below the middle of the corolla tube and the pen is about as long as the corolla tube or the stamens the uppermost portion of the corolla tube spring and the stylus is about half as long as the corolla tube.
fruit
