Etymology: Pycnospore is a compound built from two Greek-derived parts. The first, "pycno-", comes from Greek "puknos", meaning dense, thick or close-packed, and it appears in English scientific terms where something is crowded or compact. The second part, "spore", comes from Greek "spora", meaning seed or sowing, which entered English as a technical term for the reproductive units of non-flowering organisms such as fungi, algae and ferns. Put together, the word names a spore that is dense or compact in form, the kind of small reproductive cell a botanist would distinguish from looser or more loosely arranged ones. Its formation follows the same pattern as many scientific coinages, where classical Greek elements are joined to name a precise biological distinction rather than to describe anything in everyday speech.
