History
Etymology
From Ancient Greek ῥῆγμα (rhêgma, “something broken or rent asunder; a breach, cleft, fracture”) (possibly ultimately from Proto-Indo-European *bhreg- (“to break”)) + English -carp (suffix meaning ‘part of a fruit or fruiting body’) (ultimately from Proto-Indo-European *kerp- (“to harvest; to pluck”)), modelled after schizocarp. The word was probably coined by the Scottish physician and botanist William Ramsay McNab (1844–1889): see the 1871 article from the journal Nature quoted below.
