A Grammatical Dictionary of Botanical Latin

Reptatrix,-icis (s.f.III), abl.sg. reptatrice: a creeper, a crawler; in plants, perhaps denoting the development of stolons or rhizomes [> L. reptans,-antis (part.B): creeping, crawling + L. female agent suffix –trix,-icis (s.f.III)]; see agent.

NOTE: when used as an epithet it is a noun in apposition to the generic name (i.e. not an adjective).

NOTE: also that the epithet seems to be used only with genera of the feminine gender – the masculine agent suffix is –or,-oris (s.m.III);

NOTE: not –thrix,-thrichis (s.f.III), q.v., in Gk. comp.: ‘hair.’
