Floral Biology of North American Oenothera Sect. Lavauxia (onagraceae): Advertisements, Rewards, and Extreme Variation in Floral Depth
We studied the floral biology of five North American members of Oenothera L. sect. Lavauxia (Spach) Endl. (Onagraceae L.) in field and common greenhouse settings. Oenothera sect. Lavauxia floral morphology ranges from small, cleistogamous flowers (O. flava subsp. flava (A. Nels.) Garrett in Garrett) to some of the longest-tubed flowers in North America (O. flava subsp. taraxacoides (Wooton & St...
متن کاملTaxonomic changes in Oenothera sections Gaura and Calylophus (Onagraceae)
The long-recognized genus Gaura was shown recently to be deeply nested within one of two major clades of Oenothera. New molecular data indicate further taxonomic changes are necessary in Oenothera sect. Gaura. We make these changes here, including three new combinations, in advance of the Onagraceae treatment for the Flora of North America. The new phylogenetic studies show that several pairs o...
متن کاملThe correct name in Oenothera for Gaura drummondii (Onagraceae)
In 2007, Wagner and Hoch proposed the new name Oenotheraxenogaura W.L.Wagner & Hoch for the species then known as Gauradrummondii (Spach) Torrey & A. Gray (non Oenotheradrummondii Hooker, 1834). However, the authors overlooked the availability of Gaurahispida Bentham (1840) for this species. Accordingly, we herewith make the appropriate new combination for this species, Oenotherahispida (Bentha...
متن کاملThe correct name for a subspecies of Oenothera fruticosa L. (Onagraceae)
In 1978 when Straley adopted the name Oenothera fruticosa L. subsp. glauca (Michx.) Straley for one of the two recognized subspecies of O. fruticosa it was the correct name for this taxon; however, since that time the botanical code has changed so that now an autonym is treated as having priority over the name or names of the same date and rank that established it. This change means that since ...
متن کاملClimate and life-history evolution in evening primroses (Oenothera, Onagraceae): a phylogenetic comparative analysis.
Evolutionary ecologists have long sought to understand the conditions under which perennial (iteroparous) versus annual (semelparous) plant life histories are favored. We evaluated the idea that aridity and variation in the length of droughts should favor the evolution of an annual life history, both by decreasing adult survival and by increasing the potential for high seedling survival via red...
