Vegetative characteristics

The felt blackberry is a shrub .

The alternate leaves are arranged in a petiole and a leaf blade. The leaf blade is pinnate unpaired and three or five parts . The upper side of the leaves is mostly covered with star hairs, and this often makes the leaves feel soft. The undersides of the leaflets | pinnate leaves are densely tomentose. The leaflets are petiolate. The terminal leaflet is oval, obovate or rhombic with a length of 3 to 7 millimeters. The stipules are linear with a width of 0.5 to 1 millimeter.

Generative characteristics

The flowering period in Spain extends from June to August. In the cylindrical or sometimes pyramidal, densely hairy inflorescence, there are no leaves in the upper part, and below that the leaves are three-part, sometimes they can be five-part.

The hermaphroditic flowers are radial symmetry and five-fold with a double flower envelope . The five sepals are hairy and fluffy white and bent back. The five white (dried yellow) petals are 8 to 11 millimeters long and 6 to 8 millimeters wide, mostly oval, sometimes obovate or almost circular. There are many stamens. The anthers are bare. The carpels are bare.

The felt blackberry is diploid and the number of chromosomes is 2n = 14.

Spread and endangerment

Rubus canescens is widespread from Europe to Western Asia and the Caucasus . There are localities for Portugal , Spain , France (including Corsica ), Belgium , Germany , Austria , Liechtenstein , Switzerland , Italy (including Sicily ), the Czech Republic , Hungary , Poland , Slovakia , Slovenia , Serbia , Croatia , Bosnia and Herzegovina , Bulgaria , Montenegro , Romania , Albania , North Macedonia , Greece (including Crete ), Moldova , Ukraine , Crimea , Israel , Jordan , Lebanon , Turkey , Syria , Azerbaijan and Georgia .

For Germany Rubus canescens is not considered endangered; For Baden-Württemberg the data situation is insufficient, in Bavaria (there it occurs only north of the Danube) and in Hesse it is rated as “not endangered”, in North Rhine-Westphalia it is very rare, in Rhineland-Palatinate , Saarland and in Thuringia it is considered endangered with an unclear status; it does not occur in other federal states.

Rubus canescens is in the Red List of Endangered and Rare Vascular Plants of the Principality of Liechtenstein 2006 as “Critically Endangered” (= CR). Rubus canescens occurs only in small populations and only at a few locations in Liechtenstein, so it is assumed that the species can disappear completely in Liechtenstein.

In Switzerland, Rubus canescens is listed in the 2016 Red List of Switzerland's vascular plants as “Least Concern” = “not endangered”.
