BOTANICAL NOTES FROM NORTH CARDIGANSHIRE. 



supersede G. germanica Willd., which is called Q. WetMeinii Murb. 

 This course, I think, few, if any, botanists will concur in, or follow. 

 I think rather that most will retain Willdenow's name, and that 

 they will, in doing so, be acting in accordance with the Laws. 

 This will necessitate giving a fresh name to O. *germanica Murb., 

 so that the result is that our nomenclature is encumbered with 

 three new names, instead of the one new name that alone would 

 have been necessary had the course indicated above been adopted. 

 The other two names quoted are not, of course, in binomial form ; 

 but they have at least the merit of possessing a definite meaning. 

 Much must not be said, therefore, concerning such matters of 

 detail so long as we, in this country, make use of, and advocate the 

 use of, such "specific" names as Ranunculus heterophyllus Web. ex 

 parte, Rumex aguaticus L. pro parte, or Sparganinm ramosum Huds. 

 pro parte. Such expressions, like those quoted above, are contrary 

 to the Laws ; while at the same time, unlike those quoted above, 

 they are useless, because indefinite— giving neither any clue to, nor 

 authority for, nor any reference to a description or other publi- 

 cation of, the particular "part" intended. 



BOTANICAL NOTES FROM NORTH CARDIGANSHIRE. 

 By J. H. Burkilii, B.A., and J. C. Willis, M.A. 

 These notes are the result of a short stay in the county of three 

 weeks, divided equally between the following places :— -Devil's 

 Bridge, Pont Erwyd, and Pont-rhyd-fendigaed. The region ex- 

 plored includes Plinlimmon and the hills to the south of it as far 

 as Llyn Berwyn, the valleys of the Rheidol and Ystwith, the 

 upper part of the valley of the Teifi, and also the Mynydd Bach 

 hills. The geological formation is wholly silurian. The literature 

 referring to the botany of Cardiganshire is meagre ; the following 

 table summarises it. Recorded in : 



1. Watson's Topographical Botany, 2nd ed., 1883 . 491 species. 



2. Morgan's Flora Cereticat Saperioris* 458 species, 



of which Watson does not record 125 „ 



8. E. Lees, in Phytologut, i. p. 88,* 70 species, of 



which Watson or Morgan do not record ... o ,, 

 4. Report, Scientific Society of the University College 



of Wales, 1892-3. 45* species, of which the 



three preceding do not record 9t „ 



Observed by us, 332 species, of which the preceding 



do not record 30 „ 



Total (Phanerogams and Vascular Cryptogams) . 660 „ 



t Or 8, if Lamium Galeobdolon was not found on the Cardigan side of the 

 Llyfnant.
