A multivariate morphometric study of the Iberian representatives of Potentilla sect. Recta (Rosaceae)
Abstract
A multivariate analysis has been performed in order to study the polymorphisms of the three species ofPotentilla sect.Recta (Th. Wolf)Juzepchuk represented in the Iberian Peninsula:P. asturica
Rothm.,P. hirta L. andP. recta L. The variability of 20 characters (quantitative, binary and qualitative) has been evaluated in 76 collections mostly from
the Iberian Peninsula and from other European territories, but also from North America, and North Africa. The analyses performed
provide support for the recognition of the three species. The most discriminant among the quantitative characters is the width
of the long trichomes on the stem, and then the width of the long trichomes on the leaves and the maximum length of the long
trichomes. The interval of number of carpels, presence or absence of short eglandular trichomes and the abundance of long
eglandular trichomes (>3 mm) are the most discriminant ones among the qualitative ones. The taxonomical position ofP. asturica, which has been previously subordinated as a subspecies within the other two taxa, is discussed. Our results support a good
delimitation of this taxon which, on the basis of the morphological characters studied by us, seems to be morphologically
more close toP. hirta than toP. recta, but differs significantly from both. A key to the three species is provided.
... La identificación de estas plantas se ha basado en los criterios morfológicos utilizados por Tison & Malécot (2007) para separar esta especie de P. recta y de P. hirta. La delimitación de estas dos últimas especies en este trabajo no coincide completamente con la utilizada en el ámbito ibérico por Guillén & Rico (1997) y Rico et al. (2003). Según los criterios de Tison & Malécot (2007) parte de la variabilidad asignada a P. recta o P. hirta en los trabajos ibéricos -en especial la variabilidad extrema-podría entrar en la delimitación que el primer artículo atribuye a P. pedata. ...

La asignación taxonómica se ha basado en el criterio de Tison & Malécot (2007), comentando sucintamente la variabilidad expuesta para algunos taxones en trabajos de ámbito ibérico (Guillén & Rico, 1998;Rico et al., 2003). ...
... La interpretación de los caracteres de las estípulas de Guillén & Rico (1998) difiere de lo antes indicado, pues estos autores consideran que P. recta puede tener estípulas dentadas o enteras, mientras que P. hirta las tendría generalmente enteras pero en algún caso con dientes. La información proporcionada por Rico et al. (2003) es intermedia, ya que se indica que cerca de un tercio de los ejemplares estudiados de P. recta presenta estípulas dentadas, pero P. hirta siempre las presentaría enteras. ...

... Furthermore, morphometric variation in the leaves in many groups of Rosaceae has been used for delimiting species because of the leaves' extraordinary forms, venation, and margins (e.g. Crataegus : Dickinson 1986;Depypere et al. 2006;Piedra-Malagón et al. 2016; Sorbus L.: Aldasoro et al. 1998;Somlyay et al. 2016; Potentilla L.: Rico et al. 2003;Kolodziejek 2010;Dobes et al. 2013). We chose to follow the approach of Zapata and Jiménez (2012) along with additional methods to find out how many species can be recognized in the V. corymbosa complex considering distribution gaps and differences in the ecological conditions where subspecies grow. ...
Vauquelinia corymbosa (Pyreae, Rosaceae) is a shrubby sclerophyllous species largely restricted to the Chihuahuan Desert, distributed from Texas, Coahuila, and along the Sierra Madre Oriental to Hidalgo. According to a previous taxonomic revision, it comprises six subspecies. Vauquelinia corymbosa has noteworthy morphological variation, mostly in leaf characters, and the majority of its subspecies are restricted to certain areas of the desert. In this study, based on 16 morphometric characters and four anatomical characters collected from 201 specimens of the six subspecies throughout their distribution range,we ran a number of uni-, multivariate, and phylogenetic analyses to determine how many species can be recognized in this species complex. We also analyzed the gaps in morphology across geography to identify whether gaps in morphometric characters are indeed useful to separate species or if they are the result of variation related to geography. The results of the analyses coincided in recognizing that subsp. angustifolia should be considered a separate species and that the remaining subspecies are part of Vauquelinia corymbosa with remarkable morphological variation. Vauquelinia angustifolia has diagnostic characters such as very narrow leaves (0.4-0.6 cm at the middle and 0.2-0.4 cm at the base) and short petioles (1-1.5 cm) and it is restricted to the northeastern region of the Chihuahuan Desert.

The morphological variations between selected five Galium species from Libya, and the role of soil factors that affect their distribution in their natural habitats were investigated. Thirty-seven macromorphological characters (11quantitative, 26 qualitative) representing vegetative parts were subjected to numerical-taxonomic analysis. Five branches and clusters were distinguished; each was linked to a specific species. Representatives of these groups were clustered together according to characters with high factor loading in the Principal Components Analysis (PCA). The results showed congruence between the UPGMA clustering and PCA in suggesting five species groups. Seventeen soil factors were used in this assessment of soil factors responsible for the distribution of the 5 species of Galium. Calcium and chloride ions content exhibited the most significant difference (p=0.05) among the five species groups, while the other examined soil variables showed no significant differences. The relationship between the examined soil variables and the studied populations of Galium species was assessed by Principal Components Analysis (PCA). Each of the studied species of Galium was affected by one or more of the examined soil parameters.
... In Potentilla series Argenteae, Aureae, Collinae, Graciles, Multifidae, Niveae, and Rectae, and in Alchemilla, the expression of apomixis is associated with complex patterns of taxonomic differentiation, suggesting an evolutionary significant role of apomixis and polyploidy for diversification (Wolf, 1908;Asker & Fröst, 1970;Soják, 1989;Fröhner, 1995;Dobeš, 1999;Rico et al., 2003;Paule, Scherbantin & Dobeš, 2012;Soják, 2012). ...
We synthesized the results from a flow cytometric seed screen and the literature to infer the phylogenetic origin and the geographical and taxonomic distribution of apomixis in tribe Potentilleae (Rosaceae). We distinguished between regular sexuality and apomixis, the zygotic and parthenogenetic origin of the embryo, and the pseudogamous (i.e. sexual) versus autonomous origin of the endosperm. The combined evidence provides information on reproductive modes for 11 genera and 120 species. For the first time records on reproductive mode are provided for the genus Farinopsis, 29 species (from five genera), and seven series of Potentilla. Regular sexuality was observed in Aphanes, Argentina, Comarum, Dasiphora, Drymocallis, Farinopsis, Fragaria, Horkeliella, Potentilla, and Sibbaldia. Reliable evidence for apomixis is restricted to two evolutionary lineages of Potentilleae: the Potentilla core group and Alchemilla/Aphanes. Early evolutionary divergence of these lineages (approximately 50 Mya), characterized by pseudogamous and autonomous apomictic seed formation, respectively, suggests parallel origins of apomixis. Apomixis is shown to be taxonomically widespread in the whole Northern Hemisphere distribution range of Potentilla, a pattern that is explained by hybrid transfer and repeated intercontinental dispersals. Taxonomic and geographical coverage is discussed with reference to species diversity centres of genera.
Potentilla asturica, an Iberian endemic species included within sect. Recta, is typified.

Wibel (sect.Argenteae

Rupr. (sect.Chrysanthae
Wolf) was studied using multivariate statistical methods. According to k-means clustering,P. canescens stands closer toP. heidenreichii of the sect.Rivales than toP. argentea. P. collina, the other representative of sect.Argenteae, is not connected withP. canescens at all. Therefore,P. canescens should belong to sect.Rivales and not to sect.Argenteae.

Wolf were identified.P. impolita specimens did not cluster out into a separate cluster as didP. collina, P. canescens andP. heidenreichii, but formed mixed clusters with different varieties ofP. argentea s.str. Therefore,P. impolita is not worthy of the rank of species and evidently not even that of subspecies, and should be treated as a variety—P. argentea var.incanescens

Infraspecific variation of Estonian Potentilla erecta (L. ) Rausch. was studied with different morphometrical methods. Both P. erecta sap. erecta and ssp. strictissima (Zimm. ) A. J. Richards were identified with ssp. strictissima prevailing; however, several specimens are morphologically of an intermediate type. Representatives of the two taxa haveno geographical or ecological preference in Estonia, and since it wasnot possible to statistically delimit them, we preferred to treat these taxa as varieties: P. erecta var. erecta and P. erecta var. strictissima (Zimm. ) Hegi.
This new release of the package contains 27 FORTRAN and 4 BASIC programs written for IBM-PC and compatible machines and Apple Macintosh II, Plus and SE personal computers. Widely used standard multivariate methods and specific data analytical techniques, some of them suggested by the author, are represented in the package. The procedures programmed include hierarchical and non-hierarchical clustering, fuzzy classifications, block clustering, ordination, character ranking, comparison of classifications and ordinations, consensus methods, Monte Carlo simulation of distributions of partition agreement, simulated sampling based on digitized point patterns, and information theory functions for evaluating species assemblages. This paper gives general information on the programs; technical details are presented in the user’s manual.
Chromosome numbers in 80 populations belonging to 18 species of Potentilla L. subgen.Potentilla from the Iberian Peninsula and two of P. maura, a North African endemic taxon, have been counted. The basic number of chromosomes is always x=7 and these chromosomes are small (between 1 and 2 μm). For three species, the number of chromosomes is reported for the first time and, for another six, this number has been established in Iberian representatives. Moreover, new ploidy levels have been obtained for P. hispanica and P. crantzii with regard to their entire distribution area, and in P. cinerea and P. neumanniana for the Iberian Peninsula. Some taxonomic, phylogenetic and phytogeographic comments are made for several species or groups of species from the West Mediterranean region. In 13 species only one ploidy level has been found, but six species have several ploidy levels. Seven ploidy levels occur in the investigated taxa. The frequency of each ploidy level represented within Iberian Potentilla is analysed and the data are compared with those available for taxa from the rest of the distribution area of the genus.
A palynological study by LM and SEM was made of 26 taxa of Potentilia L. subg. Potentilia. It is more precise on material from 110 populations, mainly from the western Mediterranean. On the basis of morphometry, the subg. Potentilia can be said to have a stenopalynous nature, due to the absence of significant differences between the taxa studied and to the high degree of overlapping shown by their range of variation. With respect to ornamentation, which is striate, only P. rupestris pollen can be separately identified by a much more marked striation than the other species studied. An attempt was made to observe the taxonomic and phylogenetic relationships between the species of the natural groups of Potentilia on the basis of their pollen characters.
The morphological variation of four Baltic representatives of the genus Potentilla section Aurea–P. neumanniana, P. arenaria, P. subarenaria and P. crantzii was studied with multivariate methods. Altogether 41 characters were used. The most important characters for the phenetical classification are those of the epidermis: characters of stellate and glandular hairs and numbers of cells. Macromorphological characters are less important, the most useful of these being the length of sepals and stipules and the number of teeth of the central leaflet. All four species are significantly distinct. Even P. subarenaria, a putative hybrid of P. arenaria and P. neumanniana, is clearly separated. At the same time, the species are morphologically quite variable, and it is possible to distinguish subclusters (morphotypes) within P. neumanniana, P. subarenaria and P. crantzii, which are also statistically distinct. The varieties described by Wolf (1908) under the name P. verna (P. neumanniana) do not agree well with the morphs in our material. However, it can be admitted that var. typica and var. neumanniana axe prevalent, var. pseudo-incis? and var. incis? occur occasionally; only var. longifoli? can be quite clearly delimited.
The circumscription ofPotentilla has varied widely. To investigate the monophyly ofPotentilla and the phylogenetic relationships of associated genera we used nuclear ribosomal internal transcribed spacer (ITS) DNA sequences. Fourteen species ofPotentilla (sensuWolf 1908) were included, some of which represent proposed segregate genera (such asArgentina, Comarum, Drymocallis, Duchesnea, Pentaphylloides, andSibbaldiopsis), and 17 other genera ofRosoideae, usingPrunus as outgroup. Our most parsimonious tree strongly implies thatPotentilla is not monophyletic. Forcing the monophyly ofPotentilla yields distinctly longer trees. Several morphological features appear to have evolved several times independently, including the swollen receptacle (strawberry) and ternate leaves. In order to minimise nomenclatural change and to name only well supported clades,Potentilla should be split into several genera, while other previously recognised genera such asDuchesnea, Horkelia, andIvesia are best included inPotentilla. We suggest, however, that a phylogenetic nomenclature (sensude Queiroz & Gauthier 1994) might be a better solution.
