Basal 10 flowers are hermaphrodite in a hermaphrodite inflorescence and other flowers are male. All flowers are male in male inflorescences. Each male flower is flattened and each tepal is fused with each stamen in an opposite position. Male inflorescences and flowers of Juglans\u00a0 are flattened and may use similar mechanisms in Sinowilsonia<\/em>. The mechanism of the flattening may give insight to the \u201cPlanation\u201d of the Telome theory (Zimmermann 1953, 1965).<\/p>\n

Approximately 10 flowers are formed at the base of a hermaphrodite inflorescence. Five stamen-tepal complexes are fused to cover gynoecium. Furthermore, a layer of tissue with white hair covers. It is unknown the white tissue is an outer tepal, bracteole, or a bract until we investigate the developmental process and expression patterns of genes involved in these organ development.<\/p>\n

A female inflorescence is composed of female flowers. In a female flower, a gynoecium is covered with a fused stamen-tepal complexes and a fused organ covered with white hair as in a hermaphrodite flower.\u00a0 However, anthers are rudimental and shorter filaments than those in hermaphrodite flowers are not fused with tepals. Tepals are bigger and more lobed than those in hermaphrodite flowers.<\/p>\n
