BRITISH PLANT LISTS AND THEIR DISCREPANCIES 237 



capillare of T. iiiajus^ which is found on the north bank of 

 Loch Tay (" Supp. Eng. Bot./' p. 4). According to Mr. 

 N. E. Brown the T. minus of the " Linn. Herb." is T. Kochii^ 

 Fries ; but I have followed Groves and Babington in putting 

 Kochii as a van of viajus. 



Under Ranunculus acr^is the " Lond. Cat." adds Friesianus^ 

 Rouy and Fouc. and rectus (Jord.) ; but omits parvulus 

 (Wahl.), a distinct looking plant from Cairngorm, and var. 

 Nathorstii (Berl.), which is an alpine Scottish form, named 

 for me by Herr Freyn, and said by him to be identical with the 

 foreign plant from northern latitudes. I await authoritative 

 identification of the first two varieties as distinct from our 

 British named forms. Boreau, not Jordan, appears to be the 

 author of R, rectus. I see Crantz named R. sai'dous in the 

 first edition of the Stirpes ; hence it should be written (if we 

 are certain sardous is synonymous with Jiirsutus^ Curtis) = 

 R. sardous^ var. parvulus (L.), as in the " Lond. Cat." The 

 " Lond. Cat." omits any reference to the submerged flower- 

 ing Batrachium from Rescobie Loch, which I have put under 

 Drouetii (following the " Manual ") as aspergillifolius (Hiern), 

 but which Mr. Williams has recently named eradicatus 

 (Laestad.). I have omitted under R. peltatzcs, var. quinque- 

 lobtis, Koch, and the hybrid of peltatus with trichophyllus. 

 There is also a hybrid Baudotii with /leterophyllus given in 

 the " Manual," which should be added to the List. 



I do not understand the references under Barbarea being 

 cited Br., while the species is B. vulgaris^ Ait. They both 

 date from the same page of the same publication, and if we 

 write Aiton for the species why not for the genus ? but I 

 prefer in common with most authorities to use Brown as 

 the authority, since it is now a matter of common knowledge 

 that he established that and many other genera and species 

 in Aiton's " Hortus Kewensis." To be consistent we might 

 as well attribute to Sowerby the species established by 

 Smith in " English Botany," and many names now attributed 

 to Brown would have to be cited as of Aiton. 



In writing Arabis ciliata var. Jiirsuta^ Koch, I followed 

 N. E. Brown in " Suppl. to Eng. Bot." Nyman, however, 

 only gives Ireland for ciliata, Br. ; so that Mr. Marshall may 

 probably be correct in writing var. hispida, Syme. In
