Abstract
Attention has been drawn to selected examples of unusual features in the embryology of angiosperms. The study of reproductive processes through microcinematography reveals sequential stages in living material which add a new dimension to our investigations. The unusually elongated embryo sacs inMoquiniella, synergid haustoria inCortaderia andQuinchamalium, aggressive invasion by chalazal endosperm haustorium in the pedicel inOlax andOpilia, zygotic mantle inAcrotrema, highly polyploid suspensor cells inPhaseolus, undifferentiated embryo inEriocaulon, and integumentary embryos in Compositae and Orchidaceae are briefly discussed. The association of bacteria with the flower and seed ofArdisia is essential for its perfect growth. Angiocarpy inTambourissa, intracarpellary pollen grains inButomopsis, and free-nuclear proembryo inPaeonia are typical gymnospermous characters in confirmed angiosperms.
