not the Hortus Kexvensis come forth to secure our re-

I have only to add a few words respecting a kind of 

 generic names that has of late become more common 

 than Linn2eus probably would have approved, though 

 he has once or twice allowed it ; I allude to those com- 

 pounded either of two established names, or of one com- 

 bined with any other word. Of the former number is 

 Calamagrostis, formed of Calamus and Agrostis^ two 

 Linnaean 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 Cissiis, another established 

 genus, and Ampelos, a Vine ; the latter not among Lin- 

 naean names : also Elceagmis^ constructed of \.\\o old 

 Greek names, neither of which is now in botanical use 

 by itsejf. These are both expressly allowed by Lin- 

 n^us, nor indeed can there be any objection to the latter. 

 Cissampelos may certainly justify Ht/osci/amus, comiposed 

 of Cyamiis and a word denoting swine ; if not, this would 

 prove an objection to the reestablishment of CyamuSy 

 much more to the purpose than any that has been ad- 

 vanced ; for liyoscyamus having been so long and uni- 

 versally used in systematic botany, could scarcely give 

 place, even to its venerable prototype. On the same 

 ground only can several new generic names used in the 

 fern tribe, be admitted. These are formed out of Pte- 

 ris, the established generic appellation of a common 

 Brake, with some other Greek word prefixed ; as A?igi- 

 Gpteris, a Brake with a capsule, Tmesipteris^ a cloven 

 Brake, and Ccenoptem a neiu Brake. Whatever may
