herbarium ; Dr. Hedlund's opinions (or suggestions), received 

 through Mr. Ley, do not appear to have been published. 



S. Aria x torminalis. Symond's Yat, 34 (1901) ! Gathered, 

 in company with Mr. Ley, as Pyrus latifolia Syme. Bicknor 

 Eocks, 34 (October, 1892), A. Ley: " Eipe fruit dry, mealy; 

 varying from pale orange to light red." Apparently quite fertile. 



S. minima x latifolia'^ Watersmeet, 4 N. Devon (June, 1906), 

 A. Ley. Gathered for P. latifolia var. decijnens (Bechst.). Cer- 

 tainly not the Minehead (5 S. Somerset) plant, so named ; there 

 is a decided look of minima about it. Mr. Ley told me that this 

 station produced a number of curious forms ; but S. ■minima is 

 hitherto only recorded from Brecon. 



S. salicifolia [now changed to S. rupicola] x tonimialis. Cefn 

 ■Coed, 42 Brecon (June, 1899), A. Ley. Issued as ''Pyrus scan- 

 ■dica?": Professor Koene believed it to be typical ^77<2 succisa 

 Koene. ' See B. E. C. Eeport, 1899, p. 605. The same hybrid, 

 ^' nearer S. torminalis," from limestone cliffs, Dan-y-Graig, 

 41 Glamorgan (May 28th, 1896), A. Ley ct IV. A. Shoolbred^ Koene 

 ■considered this to be his Aria suecica, typical (= Cratcegus Ana 

 L. var. suecica L. = Pyrus intermedia Ehrh. = P. deciiyiens 

 Bechst. = Sorbus scandica Er.). It is certainly not the same as 

 what Dr. Hedlund names S. scandica. See Journ. Bot. 1897, 

 pp. 99-100. 



S. incisa (Eeichb.). Limestone rocks, a little north of Weston- 

 super-Mare, 6 N. Somerset (June, 1909)! Eef. No. 3401. Dr. 

 Hedlund's note was as follows :— " Sorbus incisa (coll.). {S. incisa 

 ■ consists of several incipient species [Elementararten] , w^hich are 

 not easy to separate)." With this, which has lanceolate to oval- 

 lanceolate foliage, grew a very different plant (No. 3400), much 

 nearer to one of Mr. Ley's from Cheddar Gorge (1909), accepted 

 by Dr. Hedlund as Pyrus Aria Ehrh. var. incisa (Eeichb.) ; but 

 the latter has the leaves truncate-based, whereas in my No. 3400 

 ihey are broadly cuneate, and subentire in their lower third or 

 ■quarter. Both have roundish foliage. I think that the bulk of 

 what we have hitherto regarded as typical Pyrus Aria Ehrh. will 

 prove to be Sorbus i^orrigens Hedl., not yet described. 



Evidently much further study^of the British Sorbi is needed. 

 Dr. Hedlund's address is Alnarp, Akarp, Sweden. 



CAEEX PSEUDO-PAEADOXA S. GIBSON. 

 By C. E. Salmon, E.L.S. 



This plant has been lost sight of in recent years amongst 

 British botanists, owing to its confusion with G. teretiuscula 

 forms, and I have recently looked up the following details. 



Samuel Gibson (1790 ?~1849), in the Phytologist (i, 778, 1843), 

 fjave the name Carex Pseudo-paradoxa to plants which had been 

 ■sent him on two different occasions as C. teretiuscula and 

 C paradoxa, but which, to him, clearly differed from both. He
