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.
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.
Pollination syndromes in African Marantaceae.
TLDR
The longevity of Marantaceae individuals and the omnipresence of their pollinators allowed the specialization to a given functional pollinator group, indicating potential pathways of pollinator shifts.
Bilabiate flowers: the ultimate response to bees?
TLDR
Bilabiate blossoms protect their pollen against pollen-collecting bees and at the same time render their pollination more precisely, indicating the high selection pressure towards the bilabiate syndrome.
Stamen Development in Salvia L.: Homology Reinvestigated
TLDR
Stamen development in twenty‐one Salvia species from different sections and with highly diverse staminal structures is studied, finding the sterile theca at the end of the lower connective arm, but because of secondary growth processes, its relative position is different in the adult stage.
Why Africa matters: evolution of Old World Salvia (Lamiaceae) in Africa.
TLDR
The phenotypic diversity in African Salvia is associated with repeated introductions to the continent and many important evolutionary processes, such as colonization, adaptation, parallelism and character transformation are reflected in this comparatively small group.
Towards a new classification of Salvia s.l.: (re)establishing the genus Pleudia Raf.
TLDR
Since Salvia is already highly heterogeneous in species distribution, morphology, and chromosome number, it is preferred to split the genus into molecularly well-supported clades, which may facilitate monographic studies and more focused analyses of character evolution within or between the clades.
Pattern analysis in pseudanthia
TLDR
Pseudanthia have developed along independent evolutionary lines and are not bound to a particular inflorescence structure.
