13 to 16, inclusive, which represent, respectively, Bro7rnii< eredm^ 

 B. derilis^ B. arven^l^^ B. mpei\ Fesiuea c/ujantea^ and F, elattor. 



In the fifth edition of the same work, 1754, the description, with a 

 few very insignificant changes, is the same as in the first edition, but 

 the citations of Dillenius and of Sclieuchzcr are omitted. 



In the first edition of Liinueus's Species Plantaruni, 1753, from 

 which the genus must h}^ common acceptation date, ideven species are 

 described in the following sequence: F. omna^ F, ditrliusvula^ F. 

 rul)Ta^ F. amethyst i)ia^ F, luyuros^ F. marJtuna^ F. decumhens^ F. 

 elrftioi\ F. fiuitan^^ and F. crisitata. 



Of these species F. deeumlyen^ is the type of the genus Sieglingia of 

 liernhardi; F. faltaux is Pan leaiana Jlidtav-^ Kunt/e, and F. er?stata 

 is the t^'pe of the gemis Kocleria of Persoon. 



The remainhig species are generally included by authors in the genus 

 Festuca, so that whethtM' we accept the first species, F, ovlna^ as the 

 type of the genus, or follow the historic method of residues, the result 

 in this genus is practically the same. 



Numerous other genera have, however^ been proposed for species 

 usually included in, or first referred to, Festuca, Chronologically con- 

 sidered these are as follow^s: 



VulpiaGiiiel. Fl. Bad. 1: 8. 1805. 



Only one species included, V. m/ynros {Festiiea myiirnn L,). 



Schedonorus Beauv. A^rowt. 99, 1812. (Spelled '' Si'henodoruH " in the index of 

 tlie same work.) 



Jiascd on seven species, of wdiich the first is Fcstuca elatior L. 

 Beauvois' plate also seems to })e of this species, but if so it is very 

 faulty. 



Sclerochloa Beaiiv. Agrost. 97, 177. 1S12. 



Based on Poa dam L., Poa procumhciu'^ Schreb., and Poa divaricata 

 Beauv., all of which are nomina niida^ though ^^ Poa dura L." [Cy)w- 

 Hurus duvHs L.) is evidently an error for Poa dvra Scop. Beauvois 

 figures S. dura. 



Technically, perhaps, Sclerochloa is not published by Beauvois, in 

 which view the genus would date from Beauvois in Reichenbach, Icones 

 Florae (jermanicae 1: 23. 1S34, where the first species is likewise 

 S. dura. 



This genus is generally accepted. 



Tragus Panzer, Denksdir. Acad. Mfini:!!. 1813: 296, 1814. 



Nine species were included b}^ the author, none of which arc figured. 

 The first in position is T. elatior {Festuca elatior L.). 

 There is an older Tragus of Haller, 1768.
