NOTES ON THE M LIST OF BRITISH SEED-PLANTS " 435 



be kept for one, and we therefore follow Hudson in restricting it 

 to the British plant. A. annua L. sensu restricto (Hudson FL 

 Angl. 209, 1762), moreover antedates A. autumnalis L. Sp. PL 

 ed. 2, 771, as is seen from the fact that Linnaeus quotes Hudson's 

 book in his list of authors, and also refers to it in the text, e. g. 

 under Cistus polifolius, p. 745. 



6. Eanunculus divaricatus Schrank. Messrs. Groves have 

 shown (Journ. Bot. 1907, 379) that this is a nomen confusum, and 

 the same remark applies to i?. fceniculaceus Gilib. adopted' by 

 Schinz & Thellung. The plant should stand as R. circinatus 

 Sibth. Fl. Oxon. 175 (1794). 



[14. "Act.ea nigra Miller, Gard. Diet. ed. 8 (1768), n. 1," 



adopted by Schinz & Thellung, is non-existent. Miller's name is 



A. spicata (= A. spicata var. nigra L.) ; he distinguishes as 

 A. alba Linnaeus's var. alba.] 



16. Gastalia alba. The authority for this name should stand 

 as "Wood in Eees Cyclop, vi. (1806). 



28. Barbarea lyrata Aschers. This name depends on 

 Erysimum lyratum Gilib., which was a mere substitution for 

 E. Barbarea L., and therefore still-born. The name should stand 

 as B. vulgaris [E. Br. in] Ait. Hort. Kew. ed. 2, iv. 109 (1812). 



29. Arabis stricta Huds. (1778) is antedated by A. scabra 

 All. in Misc. Taur. v. 74 (1774). 



34. Alliaria alliacea as we have pointed out above can- 

 not stand, being founded on Erysimum alliaceum Salisb., a still- 



born name. The name to be adopted is A. officinalis Andrzj. ex 

 Bieb. Fl. Taur.-Cauc. iii. 445 (1819). 



45. Teesdalea Br. should be Teesdalia. 



56. Helianthemum marifolium Miller must give place to 

 H. canum Baumgarten Enum. Stirp. Transsilv. ii. 85 (1816). As 

 Dr. Janchen points out, Cistus mar i fold us L. is a plant with some- 

 what pointed leaves, restricted to the south of France, while 

 H. marifolium Mill, is a synonym of Cistus canus L., the British 

 plant. 



H. polifolium Mill. In his monograph of Cistacece in the 

 Pflanzenreich, W. Grosser regards Cistus polifolius L. Sp. PL 

 ed. 2, 745, as a form of G. apenninus L. Sp. PL ed. 1, 529, and 

 therefore takes the earlier name for the aggregate species. But we 

 think this extension of the species will hardly commend itself to 

 British botanists. 



H. Cham^ecistus Mill. Janchen (in litt) suggests replacing 

 this by H. nummularium Mill. ( =s Cistus nwmnularius L.). 

 But there is no evidence either from Miller (whose plant has 

 white flowers) or Linnaeus, who cites for the sole habitat Mont- 

 pellier, that this is the British plant, and the specimen in the 

 Linnean herbarium does not appear to be H. Chamcecistus. 



57. Viola sylvestris Lam. This should be cited as of 

 Kitaibel in J. A. Schultes Oesterr. Fl. iv. pt. 1, 423 (1814). La- 

 marck's name is merely a substitution for V. canina L. in its
