Reproductive biology of Launaea cervicornis: A keystone species of the Balearic coastal shrublands

Aerial seed bank and dispersal traits in Anthemis chrysantha (Asteraceae), a critically endangered species

“…Although normally the pappus is thought to be a structure favoring wind dispersal of diaspores to greater distances (Llorens et al, 2009), our study demonstrated that wind was not a primary dispersal agent of the achenes of A. chrysantha, and it is likely that wind has no significance in the secondary spread either. In fact, the achenes of this species have not a pappus-based wind dispersal strategy, most probably because of an only short length of the A. chrysantha pappus (Aguado et al, 2011).…”

1011. LAUNAEA CERVICORNIS: Compositae

“…Lloren et al . (2009: 461) have shown that L. cervicornis provides no evidence of any form of seed dormancy, and no mechanism stopping achenes germinating immediately, something evident with our collections at Kew. Other species, such as L. arborescens , exhibit the same lack of dormancy, which is most probably shared by other members of sect.…”

“…This is contrary to the statement by Llorens et al . (2009: 457), who considered that L. lanifera and L. arborescens also belonged in the same section. This is incorrect – Killian placed L. arborescens in L .…”

“…and, although Llorens et al . (2009) referred to both Killian (1997) and Schütz & Milberg (1997), Schütz & Milberg mentioned nothing about infrageneric placement of L. arborescens nor indeed any other species. [NB.…”

Biological and ecological traits of anthemis chrysantha J. Gay (Asteraceae), a critically endangered species

“…Although originally the pappus was thought to be a structure favoring wind dispersal of diaspores to greater distances (Llorens et al, 2009), our study demonstrated that the wind was not a primary dispersal agent of the achenes of A. chrysantha, and it is likely that wind has no significance in the secondary spread either. In fact, the achenes of this species have not a papus-based wind dispersal strategy, as demonstrates the short length of their pappus ; Chapter 1), as occurs in several species of Anthemis .…”
