44 ANNALS OF SCOTTISH NATURAL HISTORY 



Lavatera cretica, L., is chosen for the plant which in the 

 Catalogue is called L. sylvestris, Brotero. Potentilla Fragari- 

 astrum, Ehrh., is retained ; but it is antedated by P. fragaricz- 

 folia, GmeL, " Fl. Bad." ; and P. prostrata, Moench. " Meth." 

 Scirpus maritimus, var. conglobatus, Gray, 1821, antedates, 

 Koch, I believe. 



In the Catalogue brackets are used to enclose the names 

 of some authorities for varietal names. They appear to be 

 used when a writer has described as a species a plant to 

 which is now given only varietal rank, or when a writer has 

 placed it as a variety of a species which then bore a different 

 specific or generic name from the one now employed. 



Numerous exceptions to the rule will, however, be found. 

 The following are among the instances where the name of 

 the authority should be enclosed in brackets : Castalia 

 speciosa, var. minor, DC.; Drab a incana, var. confusa, Ehrh.; 

 Cerastium triviale, var. holosteoides^ Fries ; C. glomeratum, 

 var. apetalum, Dumort. ; Arenaria verna, var. Gerardi, Wahl. 

 (it was the Alsine Gcrardi, Wahl., see " Fl. Carp.," 1814); 

 Cytisus scoparius, var. prostatus, Bailey (Bailey described it as 

 a variety of SarotJiamnus]. Among the Roses, R. pimpinelli- 

 folia, f. sptnosissima, L., was described by Linnaeus as a 

 species ; R. glauca, var. VVatsoni, Baker, and var. celerata, 

 Baker, and f. Hailstoni were described by Mr. Baker as 

 varieties of R. canina ; and R. obtusifolia, f. concinna, Baker, 

 and f. Dcseglisei, Bor., were described by their authors 

 respectively as a variety of R. canina and as a species. 

 Polygala scrpyllacea, var. ciliata, Lebel ; Statice auriculcefolia, 

 var. intermedia, Syme ; Festuca elatior, var. pratensis, Huds. ; 

 Sali.r alba, var. vitellina, Linn. ; ^S. pJiylicifolia, var. nigri- 

 cans, Sm. ; Brachypodium gracile, var. glabrescens, Syme ; 

 Festuca rubra, var. falla.r, Thuill ; Scirpus rufus, var. bifolius, 

 Wallr. ; Carex flava, var. CEderi, Retz ; Lepidium hirtum, 

 var. canescens, Gren. et Godr. (of which more anon) ; Ulmus 

 surculosa, Stokes, var. suberosa, Ehrh., and var. glabra, 

 Miller ; Carduus pycnocepJialus, var. tenuiftorus, Curtis ; 

 Agropyron repens, var. barbatum, and var. obtusum, and 

 Narcissus Pseudo-narcissus, var. lobnlaris, are other examples. 



In the preface, as already alluded to, a statement is 

 made that pre-Linnean authorities for genera are not cited.
