pachysandra (n.)

genus of small, evergreen plants, 1813, from Modern Latin (Andre Michaux,1803), from Greek pakhys "thick" (see pachy-) + anēr (genitive andros) "man" (from PIE root *ner- (2) "man"), which is used in botany to mean "stamen, having stamens" (the plant is notable for its four stamens).
