A multivariate morphometric study of the iberian representatives ofPotentialla sect.Recta (Rosaceae)

Typification of the name 'Potentilla asturica' (Rosaceae)

“…After our revision of herbarium material of the Iberian taxa included within sect. Recta, we agree with the taxonomic proposal of Guillén & Rico (1988) and Rico et al (2003), and also with the appreciation of the scarce morphological variability of P. asturica. However, the study of the herbarium material has revealed a diagnostic character of this species shows some variability with respect to that established by Guillén & Rico (1998) and Rico et al (2003).…”

“…However, a multivariate morphometric study of the Iberian representatives of sect. Recta (Rico et al, 2003) supported the recognition of P. asturica as a separate species, being more closely related to P. hirta, with which it shares the same chromosome number, 2n=14 (Delgado & Rico, 2000) than to P. recta. As indicated by Rico et al (2003), P. asturica is the less morphologically variable Iberian species included within sect.…”

“…Recta (Th. Wolf) Juzepchuck, is a diploid endemic to mountain areas in northwestern Spain and northern Portugal (Guillén & Rico, 1998;Delgado & Rico, 2000;Rico et al, 2003;Pino Pérez et al, 2011). Although this taxon has sometimes been recognized at the subspecies level [P. recta subsp.…”

“…asturica (Rothm.) Soják] it is currently accepted at the taxonomic rank which was initially described (Delgado & Rico, 2000;Rico et al, 2003;Kurtto, 2009;Pino Pérez et al, 2011). A thorough literature survey and subsequent analysis of herbarium data on the genus Potentilla in the Iberian Peninsula, led to the realization that the name P. asturica needs to be lectotypified because Rothmaler (1935) mentioned several syntypes in the protologue.…”

Parallel origins of apomixis in two diverged evolutionary lineages in tribe Potentilleae (Rosaceae)

“…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, ; Asker & Fröst, ; Soják, ; Fröhner, ; Dobeš, ; Rico et al ., ; Paule, Scherbantin & Dobeš, ; Soják, ).…”
