Pollination Syndromes of New World Salvia Species with Special Reference to Bird Pollination1
TLDR
This paper presents a complete list of all currently accepted New World Salvia species and their classification according to their pollination syndromes, focusing particularly on bird-pollinated species. Expand
Floral diversity and pollen transfer mechanisms in bird-pollinated Salvia species.
TLDR
It is considered that the driving force behind the diverse modes of reduction is the necessity to increase the distance between nectar and pollen, thereby ensuring pollen deposition on the bird's feathered head. Expand
The staminal lever mechanism in Salvia L. (Lamiaceae): a key innovation for adaptive radiation?
TLDR
A brief review of morphological key innovations in plants, elucidating their evolutionary significance in flower–pollinator interactions, and new data on Salvia, a genus being examined as an example for presumed adaptive radiation are brought together. Expand
The Staminal Lever Mechanism in Salvia L. (Lamiaceae) ‐ a Review
TLDR
It is hypothesized that structure and functioning of the staminal levers play a major role as key structures in speciation in Salvia. Expand
Mice pollinate the Pagoda Lily, Whiteheadia bifolia (Hyacinthaceae) — First field observations with photographic documentation of rodent pollination in South Africa
TLDR
Findings support the hypothesis that pollination syndromes can be used to make testable predictions about floral trait evolution due to pollinator selection. Expand
Bird pollination in South African Salvia species
TLDR
It is concluded that each of the birds could act as a pollinator and that the three co-occurring Salvia species are not mechanically isolated from each other. Expand
Hummingbird pollination in Salvia haenkei (Lamiaceae) lacking the typical lever mechanism
TLDR
To understand pollen transfer in a species lacking the lever mechanism, field investigations were carried out and morphometric measurements of both the flowers and museum skins of the observed hummingbird species were confirmed. Expand
To be on the safe site – Ungroomed spots on the bee’s body and their importance for pollination
TLDR
It is confirmed that pollen deposition on the bees’ safe sites improves pollen transfer to stigmas of conspecific flowers sti. Expand
Nectar feeding by the Cape rock elephant-shrew Elephantulus edwardii (Macroscelidea) — A primarily insectivorous mammal pollinates the parasite Hyobanche atropurpurea (Orobanchaceae)
TLDR
Cape rock elephant-shrews were found to be pollinators of Hyobanche atropurpurea (Orobanchaceae), a member of a holoparasitic plant genus, lacking up to now any detailed pollinator observations. Expand
Stefan Vogel's analysis of floral syndromes in the South African flora: An appraisal based on 60 years of pollination studies
TLDR
This study provides support for the concept of floral pollination syndromes by demonstrating the existence of strong associations between floral phenotypes and pollinators in a region of high biodiversity. Expand
