Biscutella L. Ser. Lyratae Malin. (Cruciferae) in Italia.—Discussione sui caratteri morfologici e tassonomia

Biscutella pseudolyrata (Brassicaceae, Biscutelleae), a new species endemic to NW Morocco based on morphological and molecular evidence

“…sepal and petal size, infructescence density or fruit features and indumentum; Table 1), the broad leaf variation in B. boetica does not include in any case the characteristic lyrate leaves found in B. pseudolyrata, even though in the latter species they can occasionally be spatulate to oblanceolate in a single population or individual after reduction or lack of lateral lobes (see, for instance, P04657216 and P04743559). A similar morphological variation pattern of leaves had also been described previously for other close relatives such as B. maritima (Raffaelli 1991) andB. raphanifolia (Vicente &al.…”

“…Leaf size, however, was very variable even within a single population, like in other related species (cf. Raffaelli 1991;Vicente & al. 2016a), and no special indumentum types were observed with regard to other members of the series, which makes those characters have little value for taxonomic purposes (cf.…”

“…Over 200 herbarium specimens were visually examined, and both qualitative and quantitative analyses were conducted on 26 herbarium specimens (see below), mostly on well-developed, flowering and fruiting plants. The characters observed or measured were selected from those typically used in the literature on the genus (Malinowski 1911;Guinea 1964;Maire 1967;Raffaelli 1991;Vicente & al. 2016a), together with those considered relevant according to our own experience.…”

Diversification of Biscutella ser. Biscutella (Brassicaceae) followed post-Miocene geologic and climatic changes in the Mediterranean basin

“…Biscutella didyma is the type of the series (and also the genus) and it has been treated in rather conflicting ways, sometimes including a huge number of infraspecific taxa in several regional floras and monographs (cf. Quézel and Santa, 1963;Guinea andHeywood, 1964, 1993;Maire, 1967;Pottier-Alapetite, 1979;Hedge, 1968Hedge, , 1984Raffaelli, 1991;Boulos, 1999;Fennane, 1999). Some names have usually been connected to that species at contrasting taxonomic ranks, such as B. ciliata DC., B. columnae Ten., B. depressa Willd., B. depressa var.…”

Taxonomic circumscription of the N African endemic Biscutella raphanifolia (Brassicaceae) based on morphological and molecular characters

“…Nevertheless, the morphological and phylogenetic data obtained are congruent with considering all those clades as separate species, as usually accepted in recent times (cf. Raffaelli 1985Raffaelli , 1991.…”
