Disentangling Phylogenetic Relationships in a Hotspot of Diversity: The Butterworts (Pinguicula L., Lentibulariaceae) Endemic to Italy
The genus Pinguicula (Lentibulariaceae) consists of about 100 carnivorous species, also known as butterworts. Eleven taxa are endemic to Italy, which represents a biodiversity hotspot for butterworts in Europe. The aim of our study was to provide a phylogenetic framework for the Italian endemics, in order to: a) investigate the relationships between species in this group; b) evaluate their actu...
متن کاملPhylogenetic analysis of Pinguicula (Lentibulariaceae): chloroplast DNA sequences and morphology support several geographically distinct radiations.
The genus Pinguicula is one of the three genera of the carnivorous Lentibulariaceae, comprising approximately 80 species. Phylogeny inference using nucleotide sequences of the chloroplast gene matK and the trnK group II intron, as well as a set of 32 morphological characters revealed five well-supported, major lineages within the genus. These lineages largely reflect radiations in clearly defin...
متن کاملConsequences of preformation for dynamic resource allocation by a carnivorous herb, Pinguicula vulgaris (Lentibulariaceae).
When resource availability changes frequently and unpredictably, natural selection favors flexible resource allocation; however, such versatility may be compromised in perennial plants that differentiate leaves or flowers a year in advance of their development (preformation). We investigated resource allocation by the carnivorous perennial Pinguicula vulgaris to determine whether increased reso...
متن کاملSympodial construction of Fibonacci-type leaf rosettes in Pinguicula moranensis (Lentibulariaceae).
BACKGROUND AND AIMS The leaf rosettes of the carnivorous Pinguicula moranensis follow a spiral phyllotaxis approaching a Fibonacci pattern while the stalked flowers arise from extra-axillary sites between the leaves. The organization of this rosette has been discussed by various authors, with various results. The aim of the present study was to clarify the development of the flowering rosettes ...
متن کاملPollen Morphology of Some Turkish Crocus L. (iridaceae) Species
The genus Crocus L. (Iridaceae) comprises about 80 species distributed mainly in the Mediterranean region. It is widely dispersed in Turkey; at present about 67 taxa (including subspecies and varieties) are recognized there (Mathew, 1984, 1988, 1995, 2000; Kerndorff and Pasche, 2003, 2004). The Turkish Crocus species have received attention by several workers, who have concentrated mainly on mo...
