American Journal of Botany, EarlyView.Abstract Premise Species of Deuterocohnia (17 spp.) show extraordinary variation in elevation (0–3900 m a.s.l.) and growth forms, and many have narrow geographic distributions in the west‐central Andes and the Peru‐Chile coast. Previous research using few plastid and nuclear loci failed to produce well‐resolved or supported phylogenies.

Bumblebee cost-effectiveness for sunflower pollination in isolation cages
Ekonomika Poljoprivrede (1979), 2010 The lack of pollinators during sunflower seed production in isolation cages can lower the seed yield up to 90%. That is why we analyzed the cost-effectiveness of bumblebee usage as pollinators.

Hand pollination to increase seed-set of red helleborine Cephalanthera rubra in the Chiltern Hills, Buckinghamshire, England [PDF]
, 2007 In 2007 and in previous years, as part of ongoing attempts to improve red helleborine Cephalanthera rubra seed-set, hand pollination of florets has been undertaken at a small colony of this species in Buckinghamshire, southern England.

A Pyralid Moth (Lepidoptera) as Pollinator of Blunt-Leaf Orchid [PDF]
, 2017 (excerpt) As early as 1912, mosquitoes were observed bearing the pollen masses (pollinia) of the blunt-leaf orchid, Habenaria obtusata (Pursh) Richardson, in Reese\u27s Bog, a cedar swamp at the north end of Burt Lake, Cheboygan County, Michigan, near ...

American Journal of Botany, EarlyView.Abstract Premise The carnivorous plant genus Pinguicula (Lentibulariaceae) exhibits remarkable floral diversity associated with pollination, particularly in the largest subgenus Temnoceras, which spans Mexico and Central America. Despite this diversity, the relationships between species and the evolution of key floral traits remain unresolved. Here, we

Pollination patterns in safflower (Carthamus tinctorius L.) : a thesis presented in partial fulfilment of the requirements for the degree of Master of Agricultural Science in Plant Science at Massey University [PDF]
, 1981 The influence of environmental conditions on safflower (Carthamus tinctorius L.) floret characters and insects were studied in relation to pollination in this species.

American Journal of Botany, EarlyView.Abstract Premise High‐latitude plants initiate flower primordia at least 1 year before flowering. While impacts of rising temperatures on phenology in the flowering year are well studied, the effects of warmer temperatures in the initiation year (IY; the year before flowering) are virtually unknown.

Multifunctional Bracts in the Dove Tree Davidia involucrata (Nyssaceae:Cornales) [PDF]
, 2008 Although there has been much experimental work on floral traits that are under selection from mutualists and antagonists, selection by abiotic environmental factors on flowers has been largely ignored.

American Journal of Botany, EarlyView.Abstract Premise Declines in pollinator populations can reduce pollination services to plants, resulting in lower seed production. In response to these reductions, plants could increase the probability of pollinator visitation by plastically extending floral longevity.

Experimental evidence of pollination in marine flowers by invertebrate fauna
Nature Communications, 2016 Pollen transport by water-flow (hydrophily) is a typical, and almost exclusive, adaptation of plants to life in the marine environment. It is thought that, unlike terrestrial environments, animals are not involved in pollination in the sea.
