If you want people to understand what plant you are talking about, you need to state both the full binomial (latin name) of the plant, that is, both the genus name and the species. For example, are you referring to Steyerbromelia plowmanii, Solanum plowmanii, Anthurium plowmanii, Attalea plowmanii... or some other species named after or by a guy called Plowman?
