Celebrating Nj Tea’S Unspecialized Pollination, W. John Hayden
Celebrating Nj Tea’S Unspecialized Pollination, W. John Hayden
Biology Faculty Publications
Specialized pollination systems are the source of some of the most compelling stories in natural history. There is something appealing to the human psyche about what seems to be a reciprocal agreement between a given plant and its dedicated pollinator: the plant attracts a pollinator and provides ample nectar and/or pollen as a reward for the pollinator’s service in moving pollen from anthers to stigmas while foraging for food. Of course, these organisms have neither signed agreements nor memos of understanding. Instead, it has merely proven to the benefit of the plant, over time, to form certain floral structures, and …
Nitrogen Fixation In Roots Of Ceanothus, W. John Hayden
Nitrogen Fixation In Roots Of Ceanothus, W. John Hayden
Biology Faculty Publications
Roots are usually out of sight and, therefore, out of mind.

The red roots of the 2019 VNPS Wildflower of the Year, Ceanothus americanus, are particularly important because they host symbiotic bacteria that perform the essential function of nitrogen fixation. These prominent, knobby, distinctively pigmented roots are also the inspiration for the common name Redroot, applied to many species in the genus.

Plantae Coulterianae: Thomas Coulter’S Californian Exsiccata, Gary D. Wallace
Aliso: A Journal of Systematic and Floristic Botany
An account of the extent, diversity, and importance of the Californian collections of Thomas Coulter in the herbarium (TCD) of Trinity College, Dublin, Ireland, is presented here. It is based on examination of collections in TCD, several other collections available online, and referenced literature. Additional information on historical context, content of herbarium labels and annotations is included. Coulter’s collections in TCD are less well known than partial duplicate sets at other herbaria. He was the first botanist to cross the desert of southern California to the Colorado River. Coulter’s collections in TCD include not only 60 vascular plant specimens previously …
