242 ANNALS OF SCOTTISH NATURAL HISTORY 



majority of cases is obtained. Erwin Janchen of Vienna, 

 an enthusiastic worker at nomenclature, has also published 

 a list of alterations which are necessitated in Fritsch's " Ex- 

 kursion Flora " of Austria, and also adopts a considerable 

 number of the foregoing names. He also chooses the 

 following names suggested by me in the " Annals " which 

 are not used by Rendle and Britten : Calamagrostis canescens, 

 PJiraginites vulgaris, Bronms hordeaceus, Polygonatuni odor- 

 atum, and Crepis mollis. With regard to one of these, Poly- 

 gonatuni odoratum, doubts have been expressed as to whether 

 Convallaria odorata, Miller, means our Polygonatuni officinale, 

 or rather refers to a form of P. inultiflorum. If that be 

 so, then our Polygonatuni should be called Polygonatuni 

 angulosum (Lam.), since Convallaria angulosa, Lam., "Fl. Fr.," 

 iii. 268 (1778), is earlier than P. officinale, Allioni, " Fl. 



Fed.," 131 (1785). 



The genus Erytlircea must be replaced by Centaurium, 

 Miller, "British Herbal," 1756, p. 62 ; and our plants are 

 C. unibellatum, Gilib. (Erythrtza Centaurium}, C. vulgare, Rafn. 

 (E. littoralis), C. latifoliwn (Sm.), C. pulchelluni, Druce, and 

 C. capitatum, Rendle and Britten, as Centaurion capitatum. 



Danaa cornubiense replaces Physospermum cornubiense 

 according to Dr. Janchen. Carex Hostiana, DC., has pre- 

 cedence over C. Hornschuchiana, Hoppe. ; and we must read 

 Alnus rotundifolia, Miller, vice A.glutinosa, Gaertn. ; and Dr. 

 Janchen gives good reason for rejecting Helianthemum 

 marifolium, Miller, in favour of H. camun, Baumg. it is the 

 Cistus canus, L., 1753. Coronopus vernicarius, M. and T., 

 replaces C.procumbens, Gilib. Inula squarrosa, Bernh., must be 

 substituted for /. Conyza, DC. ; and Dr. Janchen uses Matri- 

 caria suaveolens, Buchenau, instead of M. discoidea, DC. 

 Taraxacum vulgare, Schrank, precedes T. officinale, Wigg. ; 

 and Dr. Janchen uses Hieracium lanceolatum,Vill. i instea.d oflf. 

 strictum,Fries. 1 Rendle and Britten correct me in showing that 

 Nymphoides orbiculata, Gilib., must be written N. peltatum, 

 Rendl. and Brit, since peltatum was the oldest specific name. 

 Other corrections made by them are of Silene venosa, Gilib., 

 which they suggest should be .S. latifolia (Mill.), R. and B. ; 

 and if S. latifolia, Poiret, is not valid, then that must be so, 

 1 The Rev. W. R. Linton does not agree to this, but retains H. strictum, Fr.
