Floral development from initiation of primordia through anthesis was studied for three closely
related species of Agalinis. Objectives were to determine the developmental basis for the …

Many species of angiosperms have mixed mating systems in which a portion of progeny
result from self-fertilization and some from outcrossing. We show that Agalinis neoscotica …

Initiation of floral primordia begins in Agalinis densiflora with production of two lateral
adaxial calyx lobe primordia followed by a midadaxial primordium, and then primordia of two …

The sequence of events and morphology of structures were similar during early floral
development of Agalinis tenuifolia and A. fasciculata. The lateral-posterior calyx primordia …

Sagittaria (" arrowhead", Alismataceae) is a cosmopolitan monocotyledonous genus of
aquatic herbs. Five species occur in California, where Sagittaria montevidensis ssp. calycina …

We investigated the reproductive biology and breeding system of Gonolobus suberosus.
Individual plants produced an average of 25.5 flowers distributed among 3.85 …

Flowering pattern, flowering phenology, and mating system of the closely-related, interfertile
species Penstemon tenuiflorus and P. hirsutus are the same. Flowers are protandrous, but …

Premise of research. Most studies of Anacardiaceae embryology have focused on seed and
fruit development in different genera. None of them, however, included species of …

Staminate flowers of andromonoecious species are thought to be produced to increase
reproductive success through enhancing male function or diverting resources from …

The inflorescence of Anaphyllopsis americana (Engler) A. Hay consists of more than 100
flowers arranged in recognizable spirals. Each flower has four broad tepals enclosing four …
