Abstract
A new triploid agamic species, L. leonardi-llorensii , is described from coastal populations of South-West Mallorca. The new species is closely related, on morphological grounds, to the endemic L. marisolii L. Llorens, from which it could be distinguished by several morphological characters (leaves without papillae, longer calyx, more flowers per spikelet) and by a different chromosome number ( 2n = 26, L. leonardi-llorensii ; 2n = 27, L. marisolii ). The relationships between both species are discussed, and it is suggested that both taxa might share some common evolutionary history despite their divergent chromosome number. The origin of L. marisolii from L. leonardi-llorensii through chromosome fission or by a hybridization event is considered.
Highlights
The Balearicrepresentatívesof the genus Limonium have been the subject of a considerable amount of taxonomic work not totally devoid of controversy (PIGNATTI, 1955, 1959, 1960, 1962, 1963,1971; ERBEN, 1986, 1988, 1989, 1993; LLORENS, 1986a, 1986b; LLORENS & TÉBAR, 1988; ROSSELLÓ & al., 1994; SÁEZ & ROSSELLÓ, 1996).ANALES JARDÍN BOTÁNICO DE MADRID, 56(1) 1998Limonium marisolii L
Limonium marisolii has been assigned to the L. gibertii complex (SÁEZ & ROSSELLÓ, 1996) on the basis of overall morphology, but this placement is currently tested by other cytological and molecular evidence (SÁEZ & al., unpublished data)
In the course of this revisión, attention was paid to the morphological differences encountered between the western and eastern populations of L. marisolii, which were supported by different chromosome numbers and cuticular micromorphology
Summary
The Balearicrepresentatívesof the genus Limonium have been the subject of a considerable amount of taxonomic work not totally devoid of controversy (PIGNATTI, 1955, 1959, 1960, 1962, 1963,1971; ERBEN, 1986, 1988, 1989, 1993; LLORENS, 1986a, 1986b; LLORENS & TÉBAR, 1988; ROSSELLÓ & al., 1994; SÁEZ & ROSSELLÓ, 1996).ANALES JARDÍN BOTÁNICO DE MADRID, 56(1) 1998Limonium marisolii L. This species has a narrow discontinuous distribution along southern Mallorca, where it grows on the sandy slopes and on calcareous rock crevices near the seashore. Limonium marisolii has been assigned to the L. gibertii complex (SÁEZ & ROSSELLÓ, 1996) on the basis of overall morphology, but this placement is currently tested by other cytological and molecular evidence (SÁEZ & al., unpublished data). In the course of this revisión, attention was paid to the morphological differences encountered between the western and eastern populations of L. marisolii, which were supported by different chromosome numbers and cuticular micromorphology. Evidence is presented here that supports taxonomic recognition for the western populations which are hereby described as L. leonardi-llorensii
