A large collaborative effort has yielded a comprehensive study of the phylogeny and a new
subfamilial classification of the grass family (Poaceae/Gramineae). The study was …

Microenvironmental heterogeneity is important in the ecology and diversification of the rich
palm flora that inhabits neotropical rain forests. At small-0.1-10 2 m-scales, neotropical rain …

Iridaceae are one of the largest families of Lilianae and probably also among the best
studied of monocotyledons. To further evaluate generic, tribal, and subfamilial relationships …

Plastid DNA sequences evolve slowly in palms but show that the family is monophyletic and
highly divergent relative to other major monocot clades. It is therefore difficult to place the …

Gynoecium and ovule structure was comparatively studied in representatives of the basal
monocots, including Acorales (Acoraceae), Alismatales (Araceae, Alismataceae …

The circumscription and relationships of genera within the tribe Melanthieae (29
representative taxa) were evaluated using parsimony analyses of ITS (nuclear ribosomal) …

Key innovations may increase the number of taxa in a clade that possesses the proposed
innovation in comparison to its sister group that lacks the trait through either increased …

Floral development of Araceae is compared with that of other basal monocots such as
alismatids and Acorus. Flowers of Araceae, Acorus and several alismatids with spicate …

The Bromeliaceae is characterized by a 2 n chromosome number of 50, but exceptions have
been reported. These include scattered polyploids and presumed aneuploid reductions in …

The Rapateaceae is a small, mainly Neotropical family of terrestrial or occasionally epiphytic
herbs that grow on mesic, nutrient-poor sites. Some recent studies suggest that the …
