have all his Briggsii sheets. He told me in later years that he 

 found it apparently dying out, and so was disposed to regard it 

 as "possibly a quite abnormal form." To me it has looked like a 

 csesian hybrid, and for that reason I have omitted it from my 

 Handbook and from successive editions of the London Catalogue. 

 His '' fusco-ater " {" B. oigoclad^is ? " oi Handbook and London 

 Catalogue) is certainly a very different looking plant, and is not 

 only locally abundant in England but also extends to Ireland, 

 and in a modified form to the Channel Islands. It was Dr. 

 Focke who first suggested the name " B. oigocladus " for it as 

 " probably right," and to that view he held for several years. If 

 he is right, as he probably is, in now declining to accept our 

 plant as M. & L.'s B. oigocladus, it should, I suppose, either 

 remain in our list for the present as " i?. oigocladus Eogers (non 

 M. & L.)," or be altogether omitted until a more satisfactory con- 

 clusion is reached. There seems to me no room for doubt that I 

 have rightly placed it among Eu-Badulce, where B. Briggsii 

 could hardly be put. 



Dr. Focke's recent treatment of B. anglosaxonicus Gelert and 

 B. uncinatns P. J. Muell. was referred to at some length in Journ. 

 Bot. 1905, pp. 76, 77, 203, and in their case little need be added 

 here. He still holds that B. anglosaxonicns may come under 

 B. ajncidatus Wh. & N.; but he adds (p. 231) the following 

 notes: — "Species potius collectiva quam limitibus definita 

 videtur, sed quamvis planta valde variabilis sit, specimina typica 

 e terris longe distantibus ssepe inter se optime congruunt. Praeter 

 banc formam satis constantem Eogers /. c. distinguit varietates : 

 curvidens A. Ley, vestitiformis et raduloides. Speciei notas 

 atque limites bene exposuit O. Gelert I. c. sub B. anglosaxonico. 

 Haud raro vero difficile est specimina sicca a B . raduld et 

 acanthode distinguere." B. melanoxylon Muell. & Wirtg. This 

 name, given us in the first instance by Dr. Focke {vide Journ. Bot. 

 1897, p. 47) for a plant widely distributed in Scotland, and 

 occurring in several Welsh and English counties, is now [B^tbi 

 Eurojjcei, p. 216) withdrawn by him as incorrect, and " B. furvi- 

 color Focke nov. nom." substituted for it, with a short description 

 and the statement that it is " like B. melanoxylon, but differs in 

 its concolorous leaflets." None but British localities are given 

 for it. 



When we come to the Eu-Badulce — i. e. to the Badula as 

 strictly and rather narrowly limited in my Handbook (p. 5) — we 

 find substantial agreement with our names. But a place is 

 found for my subsp. anglicanus under B. macrostachys P. J. 

 Muell., as a near ally of B. radula — an arrangement for it with 

 which I have no quarrel, though on the whole I still prefer a 

 closer association of it with B. radula itself, together with 

 echinatoides, my other subsp. under the species radida, now left 

 so by Dr. Focke as " var. vel ex Eogers subsp." Both these 

 plants, easily recognized and very widely distributed in England 

 and Ireland, are quite obviously less distinctly eu-radulan than 

 B. radula itself, but they seem most helpfully placed in the closest
