Alliaceus Plants

Alliaceus Plants are primarily those of the genus Allium (Onion, Leek, Shallot, Garlic, Ramsons, Rocambole), or others nearly allied to it. The term is, however, extended to denote the possession of the characteristic odour and taste (due to the presence of an essential oil), presented in varying degrees by all members of that important genus. Thus the alliaceous flavour and odour are strongly developed in plants belonging to very different orders—e.g. the common treacle-mustard (Alliaria officinalis, natural order Cruciferae)—while certain species of Meliaceæ are used as garlic in Java.
