134 FURTHER NOTES ON HIERACIA. 



But there can be no doubt that we have three very distinct plants 

 in Britain, to which one or other of these names has usually been 

 applied. Two of these forms have already been distinguished, I 

 think beyond all doubt, and it is to the third, on Dr. Linde- 

 berg's authority, that I now apply Jordan's name. The head- 

 quarters of the plant in Britain are the limestone scars, dales and 

 pavements of Yorkshire. I have repeatedly sent the plant to Dr. 

 Lindeberg from these parts (a large ynurorum-like species with 

 softly hairy, dark green, very entire and roundish root-leaves 

 auricled at the base ; stem-leaves absent except in rare instances, 

 or where the panicle branches very low down) ; and these are his 

 determinations received from time to time: — " H. cinerascens 

 Jord. Fr. forma pedunculis periclinioque subglandulosis." " H. 

 cinerascens Jord. f." On specimens circulated through the Botanical 

 Exchange Club, under the name of H. crinigerum Fr., and which 

 were collected by the Rev. W. R. Linton at Clova, in August, 1887, 

 I made the note, " nearest H, cinerascens Jord., but peduncles 

 hardly hairy enough." Mr. Backhouse had changed Mr. Linton's 

 name to H. lasiophyllum Koch ; but when I sent them to Scandi- 

 navia, Dr. Lindeberg returned them as " H. cinerascens verum f. 

 minus glandulosa." I have a similar plant from " Falls of the 

 Bogie, Strathpeffer, E. Ross, 1889," collected by Mr. H. T. 

 Mennell. Specimens gathered by myself from clay cliffs by the 

 Almond, Perthshire, in 1888, and though less robust closely 

 resembling the Yorkshire form, were also placed to this species.

Linn of Campsie, Perth, July, 1874, collected by Dr. F. B. White. 

 Mr. Backhouse had named this plant " H. cestivwn Fr.,' ? below 

 which Dr. Lindeberg wrote, " Recte quidem I at Hierac. jestivum 



nil est llisi forma ancnstifolia Hip.rnr>ii nnrvmhnsi 



Hoc ergo : H. 



corymbosi, f. angustifolia." I purposely omit, for the present, 

 reference to any of the named varieties of H. umbellatum Linn., or 

 H. commutatum Beck. For the sake of making these notes as 

 complete as possible, I append references to the descriptions of 

 British Hieracia which have appeared since 1889.

 forme has already been used by Dr. Almguist, and Mr. Marshall 

 will doubtless suggest another.
