Description:

ђ.  Shrubs Stems 0.5 - 1 m tall, with upright twigs. Spikes with different size, needle-shaped, straight or directed downwards. Leaves 4 - 6 cm long; Leaf stems bare, rarely dotted with small glandular hairs. The stipule narrow, 2 - 4 mm wide, tipped to the tip and deviate from the stem sideways, on the top naked, bottom and edge, covered with small glandular hairs; leaflets (5) 7 - 9 (11), round to slightly elliptical, 1 - 2 cm long, on the upper side naked, lower glandular (rarely almost naked or glandular in rare cases and rare hairs) vague or double glandular jagged. Flowers 3 - 8 cm in diameter, single; flower stems 1 - 3 cm long, bare or with glandular hair and needle-shaped spikes. The sepals  entire, narrowly lance, on the tip pointed, on the outside and on the edge covered to varying degrees with glandular hairs, and from the inner smooth; After blossoming remain stretched or upright. Petals white with creamy yellow hue, longer than sepals. The columns are white fibrous. Fruit spherical to ellipsoid or disk-shaped flattened, dark to pink.

Business importance. Decorative plant. It can also be used to strengthen erosion sites. Leaves in some regions of Bulgaria are used for tea. Fruits are used for coloring liquids and for medicinal purposes. They contain vitamin C on average 680 - 715 mg% of raw mass.

Note. R. myriacantha is a slightly polymorphic species. However, the degree of variability of some scars varies with the same specimens as well as the surrounding conditions. These are the indenture of the leaflets - vague or double glandular, glandular hairs on the lower side of the leaves. Given by Stoyan. Stef., Ph. Бълг. (1948), R. pimpinellifolia var. spinosissima S. Koch and R. pimpinellifolia var. ripartii Keller are the result of this variability and have no taxonomic value. They are ecological forms. The same is true of R. pimpiènellifolia var. serbica G. Braun, reported by Al. Drenovsky (VI Contribution to Ali Botush Fossil, 1935) Hybrid forms of R. pendulina X R. myrriacantha, which in taxonomic signs approach R. pimpinellifolia, are encountered.

Flowering Time: Flowers: V - VII.
