Limonium vigoi (Plumbaginaceae) , a new tetraploid species from the Northeast of the Iberian Península

[摘要] A new tetraploid agamic species,Limonium vigoi , is described from coastal populations of the Northeast of the Spain (Ebro delta). The new species is related, on morphological grounds, toL. girardianum(Guss.) Fourr. andL. grosiiL. Llorens, from which it could be easily discriminated by its retuse leaves, the basal ones usually withered at anthesis, the very short (or even absent) leaf apiculum, the denser and longer (up to 0.7 mm) hairs of the calyx tube and the deeper colour of the corolla. In addition,L. girardianumis triploid, whereasL. vigoiandL. grosiiare tetraploid.Limonium girardianumandL. grosiishow the same pollen/stigma combination (A/cob type) which differs from that exhibited byL. vigoi(B/papillate type). The types ofLimonium girardianumf.retusumPignatti andL. glaucophyllumPignatti, two taxa described from the Ebro delta, could not be distinguished fromL. girardianum , but they clearly differed fromL. vigoi .
