Ornithophily in the subtribe Maxillariinae (Orchidaceae) proven with a case study of Ornithidium fulgens in Guatemala [PDF]
Scientific Reports, 2022 Ornithophily has been long speculated to occur in the subtribe Maxillariinae (Orchidaceae), relying either solely on micromorphological analyses or scarce field observations of undefined species. In Guatemala we were able to observe regular visits of the

Nectar secretion in a dry habitat: structure of the nectary in two endangered Mexican species of Barkeria (Orchidaceae) [PDF]
PeerJ, 2021 Barkeria scandens and B. whartoniana are endangered, endemic taxa from Mexico. They are epiphytes adapted to dry habitats. Since these plants are xerophytic, their flowers were investigated for structural adaptations to nectar secretion.

Mixed Bat‐Hummingbird Pollination Assures Reproductive Success in a Highly Variable Upper Montane Species [PDF]
Ecology and EvolutionCallianthe sellowiana is a high‐altitude species endemic to the Atlantic Forest that exhibits floral traits overlapping between ornithophily (hummingbird pollination) and chiropterophily (bat pollination), with highly variable flower color and shape and ...

Flora of Ferruginous Outcrops Under Climate Change: A Study in the Cangas of Carajás (Eastern Amazon) [PDF]
Frontiers in Plant Science, 2021 Climate change has impacted biodiversity, affecting species and altering their geographical distribution. Besides understanding the impact in the species, it has been advocated that answering if different traits will be differently impacted could allow ...

Quantitative classification of Camellia japonica and Camellia rusticana (Theaceae) based on leaf and flower morphology [PDF]
Plant Diversity, 2021 In Japan, Camellia japonica and Camellia rusticana are naturally distributed. Despite differences in their habitats and morphologies, they have been classified by various researchers as either varieties, subspecies, or species.

Historical development of ornithophily in the western North American flora. [PDF]
Proceedings of the National Academy of Sciences of the United States of America, 1994 The 129 ornithophilous plant species in western North America have floristic affinities with one or the other of four geofloras: the Arcto-Tertiary flora (101 species), Madro-Tertiary flora (19 species), Madrean-Tethyan flora (8 species), and Neotropical flora (1 species).

THE GIANT LOBELIAS: PACHYCAULY, BIOGEOGRAPHY, ORNITHOPHILY AND CONTINENTAL DRIFT [PDF]
New Phytologist, 1975 SUMMARYRecent revisions of the Asian, Jamaican and African species of pachycaul lobelias raise a number of evolutionary and biogeographical problems. Discussion of the apparent forest pachycaul ancestry of the African species is applied to problems of biogeography, pollination and Continental Drift. The available facts are accommodated in an hypothesis,

Ornithophily in the Rhamnaceae: The pollination of the Chilean endemic Colletia ulicina
Flora: Morphology, Distribution, Functional Ecology of Plants, 2005 Abstract Colletia ulicina , an endemic species from the central region of Chile, displays red, tubular, scented, nectariferous flowers at the tip of its branches. Observations at two sites during two consecutive years indicate that the hummingbird Sephanoides sephaniodes (Trochilidae) visits the flowers on a regular basis.

THE POLLINATION OF MARCGRAVIA: A CLASSICAL CASE OF ORNITHOPHILY?
American Journal of Botany, 1922 Since the publication of Darwin's investigations upon the pollination of orchids, many biologists have tended to assume that flowers which are visited by insects and birds are pollinated by these animals, and that aberrant types of floral organization are adaptations to insure cross-pollination.
