Beyond pollination syndromes? Reflections on the classifications of Federico Delpino Open
Background Pollination syndromes are typically defined as idealized pollination modes based on a canonical set of traits. As such, they are often criticized as typological rather than empirical. These syndromes are attributed to the great …

How to lose a whorl: the evolutionary and developmental biology of apetaly Open
The general plan of the core eudicot flower involves two perianth whorls, a calyx, and a corolla. However, numerous eudicots, in multiple lineages, have only one perianth whorl, generally assumed to be the calyx, resulting in apetaly. Hist…

Fungal endophytes can modulate plant invasion Open
Symbiotic organisms may contribute to a host plant's success or failure to grow, its ability to maintain viable populations, and potentially, its probability of establishment and spread outside its native range. Intercellular and intracell…

Sexual system variation in the legumes (Fabaceae): prospects for morphological, evolutionary and genomic study Open
Although the great majority of legume species are cosexual with hemaphrodite flowers, a variety of sexual systems are observed in the family including monoecy, andromonoecy, androdioecy and dioecy. Such broad terms conceal much variation, …

Report of two distinct ribotypes in ITS sequences of Phalaris arundinacea (Poaceae) in western Canada and Alaska Open
Phalaris arundinacea L. (reed canary grass) is a widely occurring grass throughout the Northern Hemisphere. In North America, it is thought to consist of introduced agricultural forms from Europe as well as native populations. During a sur…

Floral phenology of an Andean bellflower and pollination by buff‐tailed sicklebill hummingbird Open
The Andean bellflowers comprise an explosive radiation correlated with shifts to specialized pollination. One diverse clade has evolved with extremely curved floral tubes and is predicted to be pollinated exclusively by one of two parapatr…

The distribution of sexual function in the flowering plant: from monoecy to dioecy Open
In flowering plants, male and female functions are usually closely associated in the same flowers, as predicted by resource allocation theory. However, the benefits of outbreeding can lead to unisexual flowers and the physiological control…
