lish Botany,' until I had proved its specific identity by raising it from 

 seeds. Should the Tintern plant prove permanently distinct from the 

 E. platyphylla (or stricta) of our corn-fields, Reichenbach's name 

 must give place to some other which will more clearly distinguish it 

 from the E. stricta of ' English Botany;' unless, indeed, the Tintern 

 plant should prove to be the F,. stricta of Linneus, which does not ap- 

 pear likely. 



4. Hieracium rigidum ("Hartm.") — Here again the Society is in- 

 debted to Mr. Thwaites for a good supply of specimens, which it has 

 appeared desirable to send out to each member, as far as they will go. 

 Our native Hieracia are still very imperfectly understood, and no ex- 

 isting arrangement of names, or descriptions of the species, will fairly 

 stand the test of comparison with the facts in nature. Among others 

 which are not yet well understood by English botanists, is the species 

 intended under the name of H. rigidum, in Babington's Manual. 

 The specimens so labelled by Mr. Thwaites correspond passably well 

 with the description given in that work, and may be the ipsissinui 

 species intended by the name. But they by no means correspond 

 with the Teesdale specimens collected in 1844, by Mess. Gibson and 

 Backhouse, and (if I mistake not) mentioned in the ' Phytologist ' as 

 those of H. rigidum. At the time of writing this remark, my Nos. of 

 the 'Phytologist' for the three years preceding 1846 are absent from 

 home ; and therefore I refer to this work from memory only ; but four 

 specimens (not in flower, though with flower-buds visible) which were 

 kindly given to me by Mr. G. S. Gibson, labelled " Hieracium 

 rigidum " and " Hieracium rigidum, v. angustifolium " bear out 

 the remark. These Teesdale specimens, though not fully answer- 

 ing to Babington's description of " H. inuloides," correspond bet- 

 ter with specimens so labelled by the Scottish botanists, than with 

 the specimens of Mr. Thwaites. My nearest example to the latter, is 

 a specimen from Mr. Tatham, labelled " Hieracium rigidum," and lo- 

 cated from " Attermire Rocks, Settle." Under these circumstances 

 of doubt, the specimens are 'sent out to the members, in the hope of 

 eliciting definite information or suggestive remarks upon the species. 

 Is the name of " H. rigidum" correct? 



5. " Hieracium subandum ?" — There are a few specimens of a 

 plant thus interrogatively labelled by the Rev. Andrew Bloxam, who 

 finds them near Twycross, in company with H. sylvaticum and H. 

 boreale. This can scarcely be the species intended under the name 

 of " H. subaudum (Z.)," in Babington's Manual; for the leaves are 

 less " cordate clasping " at the base, than are those of specimens
