Leaf fossils of Rosa lignitum Heer have often been documented as an accessory element in mixed mesophytic forests from the Oligocene and Miocene of central Europe. Its relationship to extant rose species is not yet firmly understood because leaf morphology contributes only marginally to the current taxonomy of the genus Rosa L. In this study, we investigate which extant rose species have structural leaf characters most similar to those of R. lignitum and whether the distribution and ecology of… 
Fruit fossils of Rosoideae (Rosaceae) from the late Pliocene of northwestern Yunnan, Southwest China
TLDR
The Rubus fossils suggest that Rubus was already establishing its modern diversity in northwestern Yunnan during the late Pliocene, which is thought to be largely driven by dramatic mountain uplifts and environmental complications associated with the southeastern extension of the Tibetan Plateau.
Phylogeny and biogeography of wild roses with specific attention to polyploids.
TLDR
The ancestral area reconstruction suggests that despite an early presence on the American continent, most extant American species are the results of a later re-colonization from Asia, probably through the Bering Land Bridge, and more recent exchanges between Asia and western North America than with eastern North America.
An image dataset of cleared, x-rayed, and fossil leaves vetted to plant family for human and machine learning
Abstract Leaves are the most abundant and visible plant organ, both in the modern world and the fossil record. Identifying foliage to the correct plant family based on leaf architecture is a

Phylogenetic Relationships in the Genus Rosa: New Evidence from Chloroplast DNA Sequences and an Appraisal of Current Knowledge
TLDR
Analyses indicate that migration into North America occurred at least twice within this primarily Old World genus, and are consistent with the notion that cultivated commercial roses have a relatively narrow genetic background.

TLDR
The complexity seen in Eocene Rosaceae suggests that hybridization and polyploidy may have played a pivotal role in the early evolution of the family.

TLDR
All forms are similar in minor venation and marginal characteristics, including modified rosoid teeth which are structurally similar to platanoid teeth found in the Hamamelididae.
Systematics and Leaf Architecture of the Gunneraceae
Cladistic and phenetic analyses of leaf and other morphological characters ofGunnera strongly support monophyly of the genus, with the Saxifragaceae s.str. as the closest sister group. This
Revision of Lyonothamnus A. Gray (Rosaceae) from the Neogene of Western North America
TLDR
A renewed taxonomy within an updated temporal framework provides an important first step toward understanding the evolution, diversity, paleoecology, and paleobiogeographic history of this unusual member of the Rosaceae.

Phylogenetic analysis of Cabombaceae and Nymphaeaceae based on vegetative and leaf architectural characters
TLDR
Although the value of vegetative and leaf architectural characters is shown, inclusion of atypical leaves, for example some types of submerged leaves, results in less resolved or robust trees.
Leaf Architectural Survey of Cercocarpus (Rosaceae) and Its Systematic Significance
In a survey of nearly all extant taxa of Cercocarpus (Rosaceae), the observed patterns of leaf architectural variation have resulted in new proposals of possible relationships within the genus. Leaf
Relationships between Nordic Dogroses (Rosa L. sect. Caninae, Rosaceae) Assessed by RAPDs and Elliptic Fourier Analysis of Leaflet Shape
TLDR
A novel combination of random amplified polymorphic DNA (RAPD) markers and elliptic Fourier analysis of leaflet shape is used to investigate relationships within and between the seven common dogrose taxa in the Nordic countries.
Different levels of morphometric variation in three heterogamous dogrose species (Rosa sect.Caninae, Rosaceae)
TLDR
Morphometric diversity was analysed on seedlings obtained from field collections in South Sweden of three species of Rosa dumalis, R. rubiginosa and R. villosa and showed that the three species are relatively distinct whereas two subspecies of the species were less well discriminated.
