Fertilisation always takes place outside the conceptacle, each oosphere becoming surrounded by a number of the ciliated antherozoids (fig. 797), one of which ultimately fuses with it, forming the oospore or zygote, which then secretes for itself a cellulose covering. The zygote generally germinates at once. Besides the sexual organs the conceptacles contain a number of barren hairs or paraphyses (fig. 794), which frequently are so numerous towards the top of the cavity as to protrude through the Please note that these images are extracted from scanned page images that may have been digitally enhanced for readability - coloration and appearance of these illustrations may not perfectly resemble the original Green, J.
