Based on field research in south-central Poland, supplemented with a review of herbarium materials, we identified a stable bramble biotype with a range large enough (190 km distance between the outermost stands) to be described as a new regional agamic species, Rubus kaznowskii sp.nov. It belongs to the series Subthyrsoidei(sect. Corylifolii). Although R. kaznowskii has a unique combination of features, it can be potentially mistaken for R. gothicus . It differs from the latter species in many aspects, including: pruinose primocanes, denser indumentum of the abaxial leaf surface, and more curved prickles on the petiole. R. kaznowskii has mainly been observed on rusty soils, in habitats of mixed coniferous and mixed broadleaf forests, usually in sunny places, along forest margins and roads, in clearings and roadside thickets.

The genus Rubus is one of the largest taxonomically diverse and complex genera in the family Rosaceae. Morphology of pollen grains (equatorial and polar axes length, shape and size, aperture position, exine sculpture, perforations) is regarded as one of its main diagnostic features for identification of species and varieties. An attempt was made to fill the gap concerning the pollen micromorphology and ultrastructure of R. idaeus L. using light, scanning, and electron transmission microscopy. This study is a comparative analysis of micromorphological and ultrastructural traits of pollen from six raspberry cultivars. The pollen grains were classified as small or medium of shape prolato-spheroids. The parallel striae in the equatorial view in the exine sculpture were sometimes branched dichotomously in 'Glen Ample', 'Polka', and 'Polana', arcuate in 'Laszka' and 'Pokusa', or irregularly overlapping in 'Radziejowa'. The width of exine striae of biennial fruiting cultivars was much larger than in repeated fruiting cultivars. In terms of the increasing number of perforations per unit area of the exine surface, the cultivars were ranked as follows: 'Pokusa' < 'Glen Ample' < 'Laszka' < 'Polka' < 'Polana' < 'Radziejowa'. The thickest tectum, the highest and thickest columellae with the largest distances between them, and the thicker foot layer were demonstrated in 'Glen Ample'. The ectoexine constituted on average ca. 78-90% of the exine thickness. The findings may constitute auxiliary traits i.a. for identification of related taxa, interpretation of phylogenetic relationships, and pollination biology.
... Due to great morphological diversity, approximately 1300 species have been described within the genus (Davis 1990, Thompson 1997, Kurtto et al. 2010, and over 50 new species of brambles have been described in the recent two decades (e.g., Zieliński 2004, Zieliński & Trávniček 2004, Zieliński et al. 2004a, 2004b, Trávníček & Zázvorka 2005, Trávniček et al. 2005, Žíla & Weber 2005, Bijlsma & Haveman 2007, Király et al. 2015, Maliński et al. 2015, Wolanin et al. 2016, Beek 2017, Mikoláš 2017, Kosiński et al. 2018, Gupta & Dash 2018, Prosser & Király 2019, Wang et al. 2019, Xiong et al. 2019). However, due to widespread apomixis and repeated hybridization events within the genus, numerous morphologically defined entities have no taxonomic importance and should be assessed as temporal local biotypes (Holub 1992, Weber 1995, Kurtto et al. 2010, Sochor et al. 2015. ...
... In comparison to the north-western Europe, the number of east-central European bramble species is relatively low (Kurtto et al. 2010).

The Rubus flora of northern Wielkopolska (Greater Poland) is not yet fully discovered, but the recent studies on the genus Rubus suggest that it is clearly not as rich as in case of southern Wielkopolska. The results of the field observations show that the area of the Durowo Forest District contains 14 representatives of the genus Rubus, out of which the presence of four taxa has already been reported and confirmed. Only R. czarnunensis, species endemic to Poland and mentioned in this area in the early 20th century, was not rediscovered. The presence of two species, previously unknown in this area, R. nemoralis and R. seebergensis, have shifted their range limits by 16 km and 30 km to the north, respectively. A statistically significant higher number of bramble species occurred in pine forest growing on fertile deciduous forest habitats.

Rubus zielinskii M. M. Wolanin & M. N. Wolanin, a new species from south-east Poland is described and illustrated. Rubus zielinskii is a tetraploid (2n=28) belonging to the series Sprengeliani based on morphology. It is most similar to Rubus sprengelii from which it differs in the inflorescence, being leafy to the apex, the larger flowers, paler colour of the vegetative stem and straighter prickles. The species occurs mostly along forest roads, ditches and forest edges. A species conservation assessment for Rubus zielinskii determines its threat status to be Least Concern.

Rubus lindebergii P. J. Müll. (Rubus sect. Rubus, ser. Discolores), widely distributed in northwestern Europe, is recorded for the first time from northwestern Poland. Its locality is separated from the closest stands of this species in northern Germany by a distance of about 200 km. The species has been observed mainly in moderately fertile habitats of fresh mixed broadleaf forests, usually in fairly sunny places, along forest margins, by forest roads, in clearings, and in wayside thickets.
Rubus prissanicus, a new regional apomictic species, is described from north-western Poland. It is similar to R. lindleianus and R. langei, however it differs from the former species by broader leaflets and less numerous prickles on the inflorescence axis, and from the latter by unequally serrate leaflet margin, and from both these species by different types of trichomes on abaxial leaflet surface. Unlike other Polish species of R. ser. Rhamnifolii, in which the indumentum of abaxial leaf surface consists mainly of branched hairs, simple trichomes are the main component of indumentum of R. prissanicus leaves. The new species has been observed mainly on fertile soils, in broadleaf forest habitats, usually in fairly sunny places, along forest margins, by forest roads, in clearings, and in wayside thickets.
In forests of the Kolbuszowa Plateau, bramble thickets are common mainly in young forest plantations and clear-cut areas. 11 bramble species were found in 20 plantations visited during the field study. The most frequent bramble species in young forest plantations include: Rubus plicatus, R. nessensis, R. hirtus, R. idaeus, while less frequent are: R. gracilis, R. ambrosius and R. apricus. The largest patches of brambles were found in plantations established on sites of mixed pine-oak forest, subcontinental lime-oak-hornbeam forest and dried alder carrs. Rubus thickets in young forest plantations occur together with numerous species characteristic of communities classified into the following classes: Vaccinio-Piceetea, Querco-Fagetea, Epilobietea angustifolii, Molinio-Arrhenatheretea and Nardo-Callunetea. Brambles growing in young forest plantations can be roughly divided into three groups: I - species with thin, prostrate and rooting stems (R. hirtus, R. apricus, R. pedemontanus), which may significantly affect the growth of tree seedlings if bramble specimens or diaspores are present at the time of tree planting; II - species with strong, poorly branched and arcuate stems (R. plicatus, R. gracilis, R. ambrosius, R. glivicensis), whose negative effect on tree seedlings depends on the potential of a tree species to produce quickly a high and dense thicket thereby overshadowing the lower vegetation; III - species with erect and relatively sparsely growing stems (R. idaeus), which do not pose any threat to young forest plantations. Species with intermediate biological traits (e.g. R. nessensis) may have a negative impact on young plantations, as they generate large and dense bush, however, in most cases, their populations grow rather sparsely and do not hinder the development of tree seedlings.
In the Kolbuszowa Plateau forest areas, aggregations of brambles were observed most often in young forest plantations
and forest clear cuts. In the 20 plantations that we examined, 11 bramble species were found. The most common bramble species
in young forest plantations were Rubus plicatus, R. nessensis, R. hirtus, R. idaeus and more rarely R. gracilis, R. ambrosius and
R. apricus. The largest bramble aggregations occurred in plantations located in mixed pine-oak forests, subcontinental lime-oakhornbeam
forests and drained black alder forests. In young forest plantations the Rubus species were accompanied by species
characteristic for the Vaccinio-Piceetea, Querco-Fagetea, Epilobietea angustifolii, Molinio-Arrhenatheretea and Nardo-Callunetea
associations. There are three groups of bramble species which occur in young forest plantations: I – species with thin, prostrate
and rooting stems (R. hirtus, R. apricus, R. pedemontanus), the negative impact of which on tree seedlings could have been very
significant if the bramble specimens or diaspores had been present at the moment of tree planting; II – species with strong, poorly
branched and arched stems (R. plicatus, R. gracilis, R. ambrosius, R. glivicensis), which negative influence on tree seedlings
depends on the capability of the species to produce a big, dense bush in a short period of time thereby increasing shade; III – species
with erect and relatively sparsely growing stems (R. idaeus), which are not a threat for the young forest plantations. Species with
intermediate features (e.g. R. nessensis) may have a negative impact on young plantations generating a large, dense aggregation,
however in most cases their populations only grow sparsely and do not hinder the growth of tree seedlings.
