Can andromonoecy explain low fruit : flower ratios in the Proteaceae?
Biological Journal of the Linnean Society, 1991There are several possible explanations for the low fruit: flower ratios commonly observed in the Australian Proteaceae—some proximate and others ultimate. One of these, namely that some flowers on a plant are functionally male (andromonoecy), has recently received considerable attention.

Fruit set increases with maleness in the andromonoecious Acacia caven
Flora - Morphology, Distribution, Functional Ecology of Plants, 2014In long-lived plants, sexual expression can be highly variable in time and space. The extent to which sexual dimorphism of flowers is expressed in the same or in separate individuals, may have implications for the plants’ dependence on pollen vectors, the compatibility of the pollen received, and the potential for setting fruit.

ANDROMONOECY AND VARIATION IN PHENOTYPIC GENDER OF PASSIFLORA INCARNATA (PASSIFLORACEAE)
American Journal of Botany, 1988We studied the perennial vine Passiflora incarnata Linnaeus (Passifloraceae) in Alachua County, Florida, from May to August 1983 to determine the breeding system and investigate seasonal changes in phenotypic gender of individual plants. Passiflora incarnata is an obligate outcrosser, incapable of self‐fertilization.

Andromonoecy in Four Australian Species of Leptospermum
Australian Journal of Botany, 1990Leptospermum myrsinoides, L. juniperinum, L. laevigatum and L. lanigerum are recorded as being andromonoecious, with the proportion of total flowers that is functionally male averaging 36, 42, 48 and 14% respectively at Wilson's Promontory during the 1981-83 flowering seasons.

A Conserved Mutation in an Ethylene Biosynthesis Enzyme Leads to Andromonoecy in Melons
Science, 2008Andromonoecy is a widespread sexual system in angiosperms characterized by plants carrying both male and bisexual flowers. In melon, this sexual form is controlled by the identity of the alleles at the andromonoecious ( a ) locus. Cloning of the

Regulation of Pollen Production in Anthriscus sylvestris, an Andromonoecious Species
International Journal of Plant Sciences, 1994Pollen production per anther was investigated in relation to the gender and biomass of the flowers, their positions in the umbel, the number of flowers, the proportion of male flowers, and the sequence of flower development (order of umbel) in the common European andromonoecious species Anthriscus sylvestris. Male flowers have significantly less pollen

Floral correlations in an andromonoecious species, Commelina communis (Commelinaceae)
Plant Species Biology, 2003Abstract The sizes of various floral organs of andromonoecious Commelina communis were measured to test the hypothesis that size correlations among floral organs are regulated by natural selection.

Male flowers are better fathers than hermaphroditic flowers in andromonoecious Passiflora incarnata
New Phytologist, 2011• The diversity of plant breeding systems provides the opportunity to study a range of potential reproductive adaptations. Many mechanisms remain poorly understood, among them the evolution and maintenance of male flowers in andromonoecy. Here, we studied the role of morphologically male flowers ('male morph') in andromonoecious Passiflora incarnata. •

ANDROMONOECY IN <i>GALIUM ODORATUM</i> (RUBIACEAE)
Ботанический журнал, 2023The manifestation of sexual polymorphism in the sweet woodruff Galium odoratum was studied in the Moscow region during 2021–2023. The plant is a common perennial herbaceous, long-rhizome, polycarpic sciophyte. We find that at low illumination (less than 15% of total sunlight) only perfect flowers are formed.
