Abstract Vestigial organs arise commonly during morphological evolution, but they need not be destined for elimination. Instead, vestigial organs may facilitate functional innovation because their freedom from functional constraints allows them to assume novel roles that their functional progenitor could not perform. We illustrate this vestigial transition between functions with an experimental study of the staminode of Penstemon flowers. Previous phylogenetic and developmental studies indicate… Expand
Evolution and Development of Staminodes in Paronychia (Caryophyllaceae)
TLDR
The results illustrate a dynamic history of staminodial evolution in Paronychia and that selection on the function ofStaminodes can differ across closely related species. Expand
Functional implications of the specialized staminal appendages in alpine ginger (Roscoea spp.: Zingiberaceae)
TLDR
The results suggest that the staminal appendages are an integral component of outcrossing in Roscoea spp. Expand
Evolution of the staminode in a representative sample of Scrophularia and its role as nectar safeguard in three widespread species
TLDR
Investigation of three Scrophularia species with different staminode sizes finds that large staminodes did not hinder nectar collection or modify pollinator-visiting time but acted as a barrier to reduce rainwater entry. Expand
Tail-like anther crest aids pollination by manipulating pollinator’s behaviour in a wild ginger
TLDR
This study provides a novel example of structure adaptation in which both the male and the female functions are enhanced by resource allocation on a male organ, expanding the knowledge of the sexual roles of the anther appendage. Expand
Pollination biology of Jacaranda oxyphylla with an emphasis on staminode function.
TLDR
The staminode of J. oxyphyllla is multifunctional and its importance for female reproductive success was attributed mainly to the secretion produced by capitate glandular trichome, which is involved in complex chemical interactions with pollinating Bees Euglossini. Expand
Phylogeny, taxonomic affinities, and biogeography of Penstemon (Plantaginaceae) based on ITS and cpDNA sequence data.
TLDR
The results from these analyses show that the current circumscription of subgenera and sections needs revision to reflect more closely the evolutionary relationships of species, and confirm the independent origin of hummingbird floral morphology in 10 clades. Expand
THE EFFECT OF STAMINODE REMOVAL ON FEMALE REPRODUCTIVE SUCCESS IN A WYOMING POPULATION OF THE ENDANGERED BLOWOUT PENSTEMON, PENSTEMON HAYDENII (SCROPHULARIACEAE)
ABSTRACT We examined the effect of removing the staminode of the rare Blowout penstemon, Penstemon haydenii, on female reproductive success in a south-central Wyoming population. We found noExpand
Staminodes influence pollen removal and deposition rates in nectar-rewarding self-incompatible Phanera yunnanensis (Caesalpinioideae)
Abstract Staminodes are sterile stamens that produce no pollen, exhibit diverse structures and perform various functions. Flowers of Phanera yunnanensis possess three fertile stamens with largeExpand
Dynamic nectar replenishment in flowers of Penstemon (Scrophulariaceae).
TLDR
A limited degree of nectar homeostasis is reported here for Penstemon, suggesting mechanisms for dynamic regulation of ninator offerings, at least within broad limits, and speculate about the proximate physiology underlying this behavior and its evolutionary significance. Expand
Sexual Dimorphism in Cryptically Dioecious Thalictrum macrostylum

  • Biology
  • International Journal of Plant Sciences
  • 2014
TLDR
Lack of germination in pollen from females and 1∶1 sex ratios strongly suggest that this species is cryptically dioecious, and greater per-flower stamen number and per-plant flower number in males suggest that stamen and pollen production are important to male fitness. Expand

The evolution of staminodes in angiosperms: patterns of stamen reduction, loss, and functional re-invention.
TLDR
Indirect evolution of staminode function allows greater flexibility of function by allowing staminodes to take over roles not performed by stamens, such as involvement in mechanisms to prevent self-pollination and mechanisms of explosive pollination. Expand

It has only been during the last 10 years, through the combined use of molecular and genetic approaches, that floral aberrations have started to regain the attention of biologists. Expand
Revision of Penstemon Section Habroanthus (Scrophulariaceae). III: Series Virgati
TLDR
Of the six species, only Penstemon virgatus is highly variable, it consisting of four well-marked subspecies which are distinguishable by use of a key, maps, specimen-citations and descriptions. Expand
Pollen presentation and pollination syndromes, with special reference to Penstemon.
TLDR
It is hypothesize that bees have higher rates of removal and lower rates of deposition than birds; therefore, bee-pollinated species should have anthers that open more gradually and less completely than bird- pollinated species. Expand
Pollen Removal by Bumble Bees and Its Implications for Pollen Dispersal
TLDR
A model of pollen dispersal indicates that a constant removal proportion would maximize dispersal when the number of visits a flower receives varies little, and diminishing proportional removal would allow plants to maintain pollen dispersals when the frequency of pollinator visits is uncertain. Expand
Fluctuating asymmetry in vestigial and functional traits of a haplodiploid insect
TLDR
It is suggested that vestigial traits exhibit higher FA because of relaxation of selection for functionality, and that haploidy does not necessarily lead to increased FA in males of haplodiploid taxa. Expand

TLDR
The English translation of Knuth's handbook of Flower Pollination concludes that portion of the handbook for which that author was himself responsible, and contains the observations made in Europe and the Arctic regions. Expand
Origin of floral asymmetry in Antirrhinum
TLDR
The first gene controlling floral asymmetry, cycloidea in Antirrhinum, has been isolated and expresses at a very early stage in dorsal regions of floral meristems, where it affects growth rate and primordium initiation. Expand

TLDR
It is suggested that analysis of PCR-product restriction-site variation is useful for phylogenetic reconstruction above the species level, and a monophyletic clade of North American Cheloneae is revealed. Expand
