a kind of generic names that has of late become more common than Linnæus probably would have approved, though he has once or twice allowed it; I allude to those compounded either of two established names, or of one combined with any other word. Of the former number is Calamagrostis, formed of Calamus and Agrostis, two Linnæan names; and this is no where sanctioned by any good authority. Happily the genus to which it has negligently been applied is an Arundo. Of the latter sort is Cissampelos, formed of Cissus, another established genus, and Ampelos, a Vine; the latter not among Linnæan names: also Elæagnus, constructed of two old Greek names, neither of which is now in botanical use by itself. These are both expressly allowed by Linnæus, nor indeed can there be any objection to the latter. Cissampelos may certainly justify Hyoscyamus, composed of Cyamus and a word denoting swine; if not, this would prove an objection to the reestablishment of Cyamus, much more to the purpose than any that has been advanced; for Hyoscyamus having been so long and universally used in systematic
