416 Rev. W. A. Leighton on the Determination of the 



C. hacillaris var. clavata, Del. hb. gives K + , which proves that 

 it must be united with macilenta. In Fries (L, Suec. 52) the 

 specimens of macilenta and bacillaris are intermingled, but the 

 ticket bears the name ' C. macilenta.' There exists also a state 

 oi macilenta with granulated cortex and with the reaction (K + ) 

 analogous to Florkeana." C. albicans varr. carcata and pseudo- 

 cornuta of Delise have K + . 



36. C. rigida, Tayl. (in Lich. Antarct. 119; Nyl. Syn. 1. 

 224 n.). 



Of this antarctic species I have seen no specimen. Dr. Ny- 

 lander {in litt.) says it belongs to the series K + , and is near to 

 C. digitata. 



5ii *** Erythrocarpa (K — ) . 



37. C. sanguinea, Flk. Of this I only possess a small fertile 

 specimen from Dr. J. D. Hooker, without locality. 



Var. anamica, Nyl. (Syn. i. 21 9) . This, Dr. Nylander informs 

 me {in Hit.), has the reaction K — . 



38. C. insignis, Nyl. This, Dr. Nylander says, has K — . 



39. C. cornucopioides,Yr. (E. Bot. t. 2051) = Richardson, 30, 

 31, 33, 33, 47, 48, 49; Schser. 50, 51 ; Heppe, 538; Fellm. 

 43; Anzi, C. C. ]4, 15; M. & N. 751 (in part), 752; Massal. 

 It. 213 ; Tuck. Am. Sept. 37; Mudd, Br. CI. 65, 66, 67 ; Leight. 

 Exs. 376, 404; Spruce, Amaz. 32, 33 {L gracilescens, Nyl.). 



My herbarium contains also specimens of this, in its various 

 modifications and states, from Untersontheim (Kemler), Upsal 

 (Dr. T. M. Fries), Labrador (Breutel), Australasia (Dr. J. D. 

 Hooker), Subat and Lheris (Dr. Philippe), Leicestershire and 

 Aberdovey, North Wales (Rev. A. Bloxam), Yorkshire (Mr. G. 

 Dixon), Basingstoke, Kent (Mr. R.S.Hill), Barmouth and Cader 

 Idris, North Wales, Wrekin, Caradoc, Long Mynd, Stiperstones 

 Hills, Shropshire. 



40. C. bellidiflora, Schar. (E. Bot. t. 1894) = T. M. Fries, 

 L. Scand. 12; Massal. 173; Anzi, C. C. 16; Schar. L. H. 39, 

 40,41,42; Fellm. 46. 



Of this my herbarium contains specimens also from Savoy 

 (Dr. W. Nylander), Newfoundland (Sir W. J. Hooker), Tatra, 

 Hungary (Dr. Harslingsky), Grimsel (Schserer), Ben Lomond, 

 Scotland, 1823 ft. (Sir W. J. Hooker). 



Var. Hookeri, Nyl. (Syn. i. 221) = Spruce, Amaz. 36, 38. 



I incline to think that this and the following, deformis, may 

 be united wiih cornucopioides,SiS being states only of the same plant 

 under different development resulting from locality, situation, 

 and humidity. 



41. a deformis, Hoffm. (E. Bot. 1. 1394 ; Dill. t. xv. f. 18 a) = 

 Fellm. 44; Anzi, C. C. 17; Richardson, 50, 51, 52, 53, 54;
