THE NOMENCLATURE OF SOME SENECIOS. 259 



Calamar/rostis epigeios Roth. 5/'' Wicken Fen, in great abun- 

 dance. It is a very remarkable fact that neither in the special list 

 of Wicken Fen plants on p. 313 nor in the body of the Flora on 

 p. 270 does Babington record the species for this locality. I con- 

 sider it the most abundant plant in the Fen, more so than the 

 Schcejius, Cladimn, Peucedanum palustre, Agrostis canina, Lastrcea 

 Thelypteris, &c., which are in the Flora marked as being, and which 

 still are, abundant there. On the other hand, Babington does, on 

 both pages, record C. lanceolata Roth, though without the dis- 

 tinguishing mark of abundance in the locality. I have been unable 

 to find C. lanceolata there ; and Prof. Babington's own specimen 

 labelled " C. lajiceolata, Wicken Fen, Cambridgeshire, 20 Sept. 1855 " 

 is certainly C. epigeios, though a rather small specimen thereof. 

 Except in its differently coloured glumes (which have become 

 golden brown, as usual in the autumn), it is quite indistiuguish- 

 able from Newbould's specimens of C. epigeios from Sawston Fen. 

 The plant is still abundant in the latter locality (= Sawston Moor), 

 and is identical with that from Wicken, of which Mr. Arthur Ben- 

 nett wrote, "I suspect the f. you send thence is the var. densifiora 

 Ledebour, Flora Altaica " (vol. i. p. 87). When in flower the 

 panicle is generally streaked with a purplish black, which gives it 

 quite a different appearance from the light green one from the 

 woods of W. Cambs. The latter plant Mr. Bennett thought was 

 "perhaps the var. glauca Rchb." 



Sieglmgia decambens Bernh. 2. S.E. side of Dernford Fen, 

 sparingly. Very local in the county. 



Koeleria cristata Pers. 2. Gravel-pit near Whittlesford Station. 



Moli7iia varia Schrank. 5. Burwell Fen, 1893 ; I. H. Burkill. 



Lolium temidentum L. 3. Field by Kingston Wood, sparingly, 

 1895. 



Scolopendrium vulgare Sym. still grows in Dist. 4. 



Ophioglossum vulgatum L. 1. Mossy ground by N. end of Fleam 

 Dyke ; A. Shrubbs. 3. With Carex sylvatica Huds. in a thicket on 

 the ridge between Harlton and Haslingfield chalk-pits. 5. Baits- 

 bite, plentiful. 



THE NOMENCLATURE OF SOME SENECIOS. 



By James Britten, F.L.S. 



In so vast a genus as Senecio, any diminution of names is useful: 

 I therefore publish the following reductions, which result from a 

 comparison of the enmneration of species given by Mr. Hemsley in 

 the Botany of the Biologia Ceyitrali- Americana, ii. 235-248 (1881-2), 

 with that of Schultz Bipontinus in Flora, xxviii. 498 (1845) — a 

 list which was unfortunately overlooked by Mr. Hemsley when 

 preparing his work. These reductions are rendered the more 

 desirable because in most cases the two sets of names are retained 

 in the Index Kewensis as if representing different species. There 

 is, however, no question as to their identity in the instances I
