Abstract
Gynodioecy in the herbaceous polycarpic plant, Lomelosia songarica, from Tajikistan was identified and is described here for the first time. Three populations were studied in 2022. The plants produce flowers of two types, bisexual and pistillate, occurring on individuals of three different variants: hermaphrodite (bisexual flowers only), female (pistillate flowers only), and gynomonoecious (bisexual and pistillate flowers). The marginal flowers in floral units are irregular (transversely zygomorphic), the median ones are almost regular (actinomorphic). Two types of bisexual flowers have been identified, differing in the degree of androecium development: 1) all four stamens are fertile and produce viable pollen; 2) partially androsterile, i.e., one, two, or three stamens are sterile due to incompletely developed pollen, in this case the anthers remain closed. In pistillate flowers, rudiments of the androecium are preserved, represented by staminodes which produce no pollen. Bisexual flowers are larger than pistillate ones by most of the studied parameters. There are two types of L. songarica populations: monomorphic (consisting only of hermaphrodite individuals) and heteromorphic (gynodioecious). In the gynodioecious population, the frequency of hermaphrodite, female and gynomonoecious individuals was subequal (33.3%). The article addresses the adaptive significance of the gynomonoecious individuals of this species serving as an alternative to strictly female individuals in light of the presence of exclusively cross-pollination due to strict intra- and interfloral protandry and synchronicity of flowering of the floral units within synflorescences.
