There are four main species within streptococci&colon; the mutans, salivarius, anginosus, and mitis groups. It is synonymous of streptococcus mitis. S. pneumoniae is a recently characterized member of the S. mitis group (1). The viridans group includes "S. oralis", "S. mitis", "S. sanguis", "S. gordonii" and "S. parasanguis". It has been classified as a member of the "Streptococcus mitis" group. The barons' Latin motto is "Felis demulcta mitis" (A stroked cat is gentle). However, this finding has since been disputed&colon; see Reports of "Streptococcus mitis" on the Moon. Two subspecies are recognized&colon; "L. p. pardalis" and "L. p. mitis". The silver monkey was previously considered a subspecies of the blue monkey ("Cercopithecus mitis"). Guzmania mitis is a plant species in the genus "Guzmania". Calamondin orange ("Citrus mitis") exhibits all of those activities. "Doctorum Principem/Melodia Suavissima/Vir Mitis", surviving in the manuscript Bologna Q15. Yellow and Grey Reindeer moss ("Cladonia mitis") provide ground cover. The species' host plant is the "Caryota mitis", also known as the fishtail palm. This would make "Persicaria mitis" an illegitimate name; however it has been conserved.
