Morphological and ITS sequence divergence were assessed between the two presently recognized taxa of the endemic genusCuminia (Lamiaceae), on Masatierra of the Juan Fernandez Islands. Morphological studies were based on leaf morphology of 51 individuals. Individuals ofC. fernandezia have narrow and lanceolate leaves with cuneate to acute bases and apices, whereas individuals ofC. eriantha have broadly ovate leaves with rounded bases and acute to obtuse apices. The two taxa can also be…

A systematic study of Glechoma L. (Lamiaceae) based on micromorphological characters and nuclear ribosomal ITS sequences

The petal and sepal micromorphology of five species of Glechoma (Lamiaceae) was investigated to evaluate their taxonomic significance, and a molecular phylogeny using the sequences of internal

This work investigates the diversiWcation of Micromeria on the Canary Islands and Madeira at the interand infraspeciWc level using inter simple sequence repeat PCR (ISSR), the trnK-Intron and the trNT-trnL-spacer of the cpDNA and a low copy nuclear gene.

Consideraciones sobre la sistemática de las familias y los géneros de plantas vasculares endémicos de Chile Systematic considerations of Chilean endemic vascular plant families and genera

This study aims at discussing modifications in taxonomy and contributing to the correct delimitation of endemic genera, using updated databases and bibliographic sources and emphasizing the discussion on those genera with ambiguous classification status.

Radiation of the endemic genus Dendroseris (Asteraceae) on the Juan Fernandez Islands: evidence from sequences of the its regions of nuclear ribosomal DNA

Phylogenetic relationships among nine of the 11 species of the endemic genus Dendroseris on the Juan Fernandez Islands were inferred from nucleotide sequences of the internal transcribed spacer regions (ITS) of the 1 8-26S nuclear ribosomal DNA, supporting the hypothesis of rapid adaptive radiation of DENDroser is on the islands.

Evolution of Rhaphithamnus venustus (Verbenaceae), A Gynodioecious Hummingbird-Pollinated Endemic of the Juan Fernandez Islands, Chile

It is hypothesized that evolution of floral features in R. venustus is a result of a change from pri­ marily insect to hummingbird pollination; loss of thorns may result from ab­ sence of herbivores in the Islands.

Systematics, biogeography and conservation of Lactoridaceae

Recommendation is that the lone species of Lactoris is placed as a monotypic order, Lactoridales, allied most closely to Aristolochiales, and also near Piperales, and genetic variation within and among populations as measured by isozymes and RAPDs is low.

ITS Sequences and the Phylogeny of the Genus Robinsonia (Asteraceae)

ITS sequences provide strong support for the monophyly of Robinsonia, and relative rate tests indicate that the molecular clock cannot be rejected for ITS sequence evolution in Robinsonia.

Use of RAPD markers to document the origin of the intergeneric hybrid×Margyracaena skottsbergii (Rosaceae) on the Juan Fernandez Islands

Bands of random amplified polymorphic DNA (RAPDs) were used as markers to test the hypothesis that the species xMargyracaena skottsbergii, which is endemic to the island of Masatierra in the Juan

Endemism in the vascular flora of the Juan Fernandez islands

The Juan Fernandez archipelago contains 361 vascular plant species including 53 ferns, 65 monocots, and 243 dicots, which are definitely in a fragile state with 75% of the species being regarded as either extinct, threatened, rare, or occasional.

Systematic relationships of theLactoridaceae, an endemic family of the Juan Fernandez Islands, Chile

Cladistic analyses indicate that the Lactoridaceae family is a relatively derived member of theMagnoliales, with affinities to Annonaceae, Eupomatiaceae, Himantandraceae, andMyristicaceae.

Natural Interspecific Hybridization in Gunnera (Gunneraceae) of the Juan Fernandez Islands, Chile

Natural interspecific hybridization between Gunnera bracteata and G. peltata in the Juan Fernandez Islands, Chile, is analyzed morphologically and chemically and it is suggested that introgressive hybridization is occurring in Quebrada Villagra between these two wind-pollinated species.

Chromosome numbers from the flora of the Juan Fernandez Islands

Eighteen chromosome counts are reported from populations in 12 species from the Juan Fernandez Islands, Chile, plus three counts from taxa of the adjacent main land. First reports are given for
