Haartman (1751) where in discussing hybrid plants Linnaeus denoted the supposed female parent species by the sign ♀, the male parent by the sign ♂, the hybrid by ☿ 'matrem signo ♀, patrem ♂ & plantam hybridam ☿ designavero'. In subsequent publications he retained the signs ♀ and ♂ for male and female individuals but discarded ☿ for hybrids; the last are now indicated by the multiplication sign ×.
