Recent re-examinations and new fossil findings have added significantly to the data
available for evaluating the evolutionary history of the monocotyledons. Integrating data from …

Orchids are the most diverse family of angiosperms, with over 25 000 species, more than
mammals, birds and reptiles combined. Tests of hypotheses to account for such diversity …

A DNA barcode is a DNA fragment used to identify species. For land plants, DNA fragments
of plastid genome could be the primary consideration. Unfortunately, most of the plastid …

Background At present, plant molecular systematics and DNA barcoding techniques rely
heavily on the use of chloroplast gene sequences. Because of the relatively low evolutionary …

Background Molecular evolutionary studies share the common goal of elucidating historical
relationships, and the common challenge of adequately sampling taxa and characters …

A taxonomic revision of Bromeliaceae subfam. Tillandsioideae is presented based on a
multi-locus DNA sequence phylogeny (viz., plastid DNA loci rpoB-trnC-petN, trnK-matK-trnK …

• Premise of the study: The opuntias (nopales, prickly pears) are not only culturally,
ecologically, economically, and medicinally important, but are renowned for their taxonomic …

Background Eriocaulon is a wetland plant genus with important ecological value, and one of
the famous taxonomically challenging groups among angiosperms, mainly due to the high …

Abstract Background and Aims The largest subfamily of orchids, Epidendroideae, represents
one of the most significant diversifications among flowering plants in terms of pollination …

Tropical rainforest hyperdiversity is often suggested to have evolved over a long timespan
(the 'museum'model), but there is also evidence for recent rainforest radiations. The …
