Genus	Hypochaeris	It is not clear to me what the derivation of this name is. The entry for Hypochoeris [note spelling] in Stearn’s Dictionary of Plant Names says “a name used by Theophrastus for this or a related genus,” and Hypochoeris was the named published by Linnaeus in 1753. However he published it subsequently as Hypochaeris. The prefix hypo- means “below, beneath or under,” and suggests physical directionality or location, not quantity or amount, as opposed to hyper-, “above or over.” Edmund Jaeger’s A Source-Book of Biological Names and Terms says that the root chaer- derives from the Greek choiros, “a young pig.” The Jepson Manual 1st edition says “Greek: less then joyous, from weedy habitat.” The Jepson Manual 2nd edition says “Unabridged note: Etymology differs from that in FNANM, where the etymology on the Greek ‘choeris’ for pig; the correct spelling is ‘chaeris’ for joy.” Flora of North America says: “Cat’s ear, swine’s succory [Greek hypo, ‘beneath,’ and choiras, ‘pig,’ alluding to pigs digging for roots].”
