We compared the floral biology of two sympatric populations of closely related species over two seasons. In 2018,  Nothoscordum bivalve  (L.) Britton bloomed from April 23 to May 7 and  Allium stellatum  Nutt. Ex Ker Gawl bloomed from August 28 to October 4. Erect, white flowers of  N. bivalve  were scented and had septal nectaries. Erect, pink-purple flowers of  A. stellatum  had septal nectaries, no discernible scent, and a style that lengthened over the floral lifespan. Both species were…

Floral Biology of an Alabama Population of the Federally Endangered Plant, Xyris tennesseensis Kral (Xyridaceae)
TLDR
It is concluded that, unlike some endangered plant species, insect pollination is not required for seed production by X. tennesseensis and flowers produce seeds without visitation by insects, likely by self-pollination.
Pollination Ecology of Cypripedium reginae Walter (Orchidaceae): Size Matters
TLDR
While a diverse range of floral visitors to C. reginae were observed over three seasons, only six medium-sized bees carried segments of massulate pollinia after three seasons of observation and collection, showing no relationship between the length of the secondary flowering stem, the number of foliage leaves on the same stem and thenumber of flowers produced at the terminus of the stem.
Comparative analysis of late floral development and mating-system evolution in tribe Collinsieae (Scrophulariaceae s.l.).
Species of Collinsia and Tonella, the two sister genera of self-compatible annuals that constitute tribe Collinsieae, show extensive variation in floral size and morphology and in patterns of stamen
Bee pollination of facultatively xenogamous Sanguinaria canadensis L.
TLDR
Facultative xenogamy in this spring flowering species is adaptive because the flowers were cross-pollinated by bees when conditions favored pollinator activity but self- pollinated whenpollinator activity was suppressed by cool and/or rainy weather.
Flowering Ecology of Some Spring Woodland Herbs
TLDR
It is suggested that flowering in early spring is a high-risk option in terms of insect- mediated sexual reproduction and constraints on flowering phenology are discussed, including the predictability of suitable conditions.
POLLEN‐OVULE RATIOS: A CONSERVATIVE INDICATOR OF BREEDING SYSTEMS IN FLOWERING PLANTS

  • Biology, Medicine
    Evolution; international journal of organic evolution

TLDR
The overall objective is to show that PIO's reflect the likelihood of sufficient pollen grains reaching each stigma to result in maximum seed set and suggest that PI O's are integrated with other facets of a plant's breeding system.
Pollen‐Pistil Interactions in North American and Chinese Cypripedium L. (Orchidaceae)
TLDR
There are additional factors aside from low pollinator visitation for low conversion rates of flowers into fruits in these Cypripedium species, which include inadequate pollen loads deposited on receptive stigmas (pollen limitation), coupled with environmental stress and/ or predation disrupting or destroying the slow processes of fertilization and/or fruit maturation.
Floral Biology and Self-Incompatibility in Some Australian Mistletoes of the Genus Amyema (Loranthaceae)
TLDR
In vitro pollination experiments revealed that xenogamous crosses are most successful in the production of pollen tubes in the style although geitonogamy may act as a 'fail safe mechanism' at varying levels under natural condltlons in A miquelii (Lehm, ex Miq) Van Tiegh.
Variation in Nectar Volume and Sugar Concentration of Allium ursinum L. ssp. ucrainicum in Three Habitats
TLDR
Both the amount and quality of nectar were affected by microclimatic conditions and soil properties and varied between populations at different habitats.
Comparative Floral Structure of Four New World Allium (Amaryllidaceae) Species
TLDR
Results from this study indicate that shape and distribution of cuticles are of systematic significance in conjunction with location of the septal nectary opening, development of ovarian processes, and shape of anther apexes.
