Satyrium microrrhynchum inflorescence

    Satyrium microrrhynchum inflorescence

    The inflorescence of Satyrium microrrhynchum is an erect, dense spike of non-resupinate, fragrant flowers. From 12 to 56 flowers are borne.

    The lip is positioned over each flower column, the other five perianth segments less elaborate, all pendent below the column. All of this sets the scene for insect partners to perform pollen transportation onto stigmas of neighbouring flowers.

    The pair of pollinia, male component of procreation, is positioned (as is usual in orchids), in the central flower column opposite the median sepal.

    In orchids, there are no stamens opposite the inner circle of perianth segments (the petals and lip), while the outer circle of segments also lacks stamens opposite the pair of lateral sepals (Johnson, et al, 2007, American Journal of Botany, 94(1), pp. 47-55; Wikipedia; www.orchidspecies.com).
