Oil-producing flowers of Sisyrinchium species (Iridaceae) and their pollinators in southern South America
(Elsevier Gmbh, 2001-12)
The floral relationships existing between the mainly New World genus Sisyrinchium (Iridaceae) and oil-collecting bees were investigated in southern South America. In addition to a single species known before as producing ...
The spatial dynamics of diversity in Centridini bees: the abundance of oil-producing flowers as a measure of habitat quality
(2011)
It is assumed that oil bees in the tribe Centridini and oil flowers in the family Malpighiaceae have a conservative evolutionary association, and it is postulated that they also have a tight ecological relationship. Here, ...
Notes on oil sources for the bee genus Caenonomada(Hymenoptera, Apidae, Tapinotaspidini)
(Sociedade Brasileira De Entomologia, 2009)
It is reported for the first time oil collecting by bees of the genus Caenonomada on flowers of Plantaginaceae. Females of Caenonomada unicalcarata were observed collecting oil on flowers of Angelonia cornigera, and males ...
Leaf and flower essential oil compositions of Gliricidia sepium (Fabaceae) from Costa Rica
(2015-04)
Gliricidia is a small genus of flowering plants in the Fabaceae family. Gliricidia sepium is a multipurpose tree native to Mesoamerica and possibly northern South America. The chemical composition of the hydrodistilled ...
Chemical variability between different organs of the medicinal plant casearia sylvestrisVariabilidade química entre diferentes órgãos da planta medicinal casearia sylvestris
(2018-01-01)
The phytochemical profile of essential oils and extracts from Casearia sylvestris leaves, flowers and fruits have been investigated here. Leaf and flower extracts were prepared by sonication and analyzed by thin-layer ...
Pterandra pyroidea: a case of pollination shift within Neotropical Malpighiaceae
(Oxford Univ PressOxfordInglaterra, 2011)
Influence of organic and chemical fertilization on the yield of flowers, contents and composition of essential oil of (Chamomilla recutita (L.) Rauschert)
(1999-12-01)
A field experiment was conducted with chamomile (Chamomilla recutita [L.] Rauschert), in an area of the Olericulture and Medicinal Plants of the Horticulture Department at UNESP - Jaboticabal Campus, with the aim to evaluate ...
Teasing out the functional groups of oil-collecting bees in the light of the pollination of Nierembergia flowers
(Springer, 2021-08)
Pollination interactions between plants bearing oil-flowers and oil-collecting bees are regarded as specialized, and within the major group of bees,oil-collecting bees are considered a special functional group of pollinators, ...
Evolutionary lability in floral ontogeny affects pollination biology in Trimezieae
(Wiley-Blackwell, 2021-05-21)
Premise There is little direct evidence linking floral development and pollination biology in plants. We characterize both aspects in plain and ornamented flowers of Trimezieae (Iridaceae) to investigate how changes in ...
