4 CONTRIBUTIONS FROM THE NATIONAL HERBARIUM. 



Castellia Tineo, PL Rar. Sic. 2: 17. 1846. 



Based on a single species, C. tuherculata Tineo, which is Festuca 

 tuberculosa (Moris) Richter. 



Ctenopsis De Notaris, Ind. Sem. Hort. Gen. 352. 1847. 



A single species, O. p&ctinella De Notaris. {Festuca pectinella 

 Delile.). Retained as a genus by Bentham and Hooker, but reduced 

 to Festuca by Hackel. 



Leucopoa Griseb. inLedeb. Fl. Ross. 4: 383. 1853. 



One species, L. sihirica Griseb. Bentham and Hooker reduce this 

 to Poa, and Hackel to Festuca. 



The species is clearly closely related to the West American Poas of 

 thQ fendleriana group. Its only distinctive character is the awn-like 

 excurrent midrib of the lemma, which character is approached by Poa 

 subaristata Scribner. The genus, if not maintained, belongs with Poa 

 and not with Festuca. 



Amph.ig'enes Janka, Linnaea 30: 619. 1860. 



Based on Festuca carpathica Dietr. 

 Prosphysis Dulac, Fl. Haut. Pyr. 67. 1867. 



The author quotes Nardurus Reichenb. as a synonym and includes 

 but one species, P. tenellus^ based on Nardurus tenellus Reichenb. 

 This plant is considered by Ascherson and Graebner to be the same as 

 Festuca maritima L. 



Synaphne Dulac, Fl. Haut. Pyr. 90. 1867. 



The only species is S. rigida {Sclerojpoa rigida Griseb.) 

 Distomomischus Dulac, Fl. Haut. Pyr. 91. 1867. 



The author quotes Vulpia Gmel. as a synon3^m and includes four 

 species in this sequence: P. sciuroides {Festuca sciuroides Roth), P. 

 myuros {Festuca my uros L.), P. ciliatus {Festuca ciliata Danth.) and 

 P. subuniglum.is {Festuca hromoides L.). None of these species are 

 figured. 



Drymonaetes Ehrh. 



This name occurs in Ehrhart, Beitrage 4: 147. 1789, but is first 

 technically published as a genus in a paper by Fourreau, Ann. Soc. 

 Linn. Lyon n. s. 17: 187. 1869. The only species is based on Festuca 

 gigantea (L.) Vill. 



Loretia Duval-Jouve, Rev. Sci. Nat. II. 2: 38. 1880. 



Four species were described by the author as belonging to this 

 genus, arranged as follows: Loretia setacea based on Festicca setacea 

 Guss. ; Z. incrassata based on Bromus incrassatus Lam. ; Z. geniculata 

 based on Bromus geniculatus L. ; and Z. ligustica based on Bromus 

 ligusticus All. No figures are published by Duval-Jouve, but he cites 

 plates for each of the above species.
