Breeding systems play an essential role in plant sexual reproduction and influence
speciation and extinction processes. However, our understanding of the breeding systems …

Perfume flowers (sensu Vogel 1) produce intense scents that function both as attractants
and as the sole rewards for pollinators. The scent is collected exclusively by male …

The authors provide a new circumscription for genera of the “Cryptanthoid complex” of
Bromeliaceae subfam. Bromelioideae, originally composed of Cryptanthus, Lapanthus …

Reproductive isolation is of fundamental importance for maintaining species boundaries in
sympatry. Here, we examine the genetic and morphological differences between two closely …

The study of pollen morphology has historically allowed evolutionary biologists to assess
phylogenetic relationships among Angiosperms, as well as to better understand the fossil …

Aim Pilosocereus is one of the richest and most widespread genera of columnar cacti,
extending from south‐west USA to southern Brazil. Most species occur in the seasonally dry …

Here, we explore the historical and contemporaneous patterns of connectivity among
Encholirium horridum populations located on granitic inselbergs in an Ocbil landscape …

Geophytes, plants with buds on underground structures, are found throughout the plant tree
of life. These below ground structures allow plants to inhabit highly seasonal and …

The tank-epiphytic clade of berry-fruited bromeliads, also known as the Core Bromelioideae,
represents a remarkable event of adaptive radiation within the Bromeliaceae; however, the …

The role of geography and ecology in speciation are often discussed in the context of
phylogenetic niche conservatism (PNC), the propensity of lineages to retain ancestral niche …
