NOTES ON THE "LIST OF BRITISH SEED-PLANTS " 441 



367. Ulmus glabra Huds. (1762). Schinz & Thellung wish to 

 substitute for this U. scabra Mill. (1768). Hudson's plant is the 

 Wych Elm ; he has only two species, carnpestris and glabra, 



371. Betula. B. pendula Both Tent. Fl. Germ. i. 405 

 (1788) must replace B. verrucosa Ehrh. (1791). For B. alba, 

 Schinz & Thellung prefer to use B. tomentosa Reith & Abel 

 (1790), regarding alba L. as a nomen confusum. 



372. Alnus glutinosa Gaertn. 1791. For this must be substi- 

 tuted A. rotundifolia Mill. Diet. Abridgm. ed. 6, n. 1, 1771. 



386. Potamogeton Zizii Koch (1827). For this must be sub- 

 stituted P. angustifolius Bercht. & Presl Bostlin, 19 (1823) (see 

 A. Bennett in Journ. Bot. 1889, 265). Schinz & Thellung quote 

 P. Zizii as of Mert. & Koch in Bohlings Deutschl. Flora, 1823, 

 845, but the name is only mentioned there in synonymy. 



P. flabellatus Bab. (1851) is antedated by P. interruptus 

 Kitaibel ex Schult. Oesterr. Fl. ed. 2, i. 328 (1814). 



393. Alisma Plantago should be A. Plantago-aquatica L. 



404. Habenaria Montana. As shown by Gelakovsky (Lotos, 

 1870, 177), Orchis montana Schmidt is not a synonym of H. 

 chlorantha Bab. but a form of H. bifolia ; hence the name H. mon- 

 tana must be abandoned. The earliest name is Orchis virescens 

 Zollikofer in Gaud. Fl. Helvet. v. 497 (1829) ; and the plant must 

 stand under Habenaria as H. virescens Druce in Ann. Scott. Nat. 

 Hist. 1907, 244. 



[405. Ophrys fuciflora H. G. Beichenb. Schinz & Thellung 

 abandon this name as a nomen odiosum, which they say could 

 not be used in Swiss school-floras.] 



411. Epipactis. In his Dillenian Herbaria, 115, Mr. Druce 

 substitutes Helleborine Hill for Epipactis, and we agree with this 

 substitution, the reasons for which will be pointed out in the 

 next number of this Journal. The species will therefore stand 

 thus : 



Helleborine Hill (Brit. Herbal, 477) 1756 



1. H. latifolia Druce Dill. Herb. 115 (1907). 



2. H. media Druce /. c. 



3. H. violacea Druce I. c. 



4. H. atrorubens Druce I. c. 



5. H. longifolia comb. nov. 



Schinz & Thellung retain the name palustris for the last species, 

 as they consider that the use of Serapias longifolia by Linnaeus 

 in Sp. PI. ed. 2 as an aggregate precludes its use by him in a 

 more restricted sense in the Sy sterna, ed. 12. We however adhere 

 to the view already expressed in this Journal (p. 105). 



412. Cephalanthera grandiflora S. F. Gray. Schinz & 

 Thellung, following Janchen, employ his new combination for this 

 species — G. latifolia (Miller) E. Janchen in Mitteil. Naturw. Ver. 

 Univ. Wien, v. Ill (1907) — on the ground that Serapias Dama- 

 senium Miller ( = C. Damasonium Druce) is complicated and 

 confused, while S. latifolium is clear and obvious. Any confusion
