REPOBT OF THE BOTANICAL EXCHANGE CLUB. 183 



Caucalis latifolia, Linn. " Cornfields, near Kn<iiisliavern, Gloncester- 

 shire. Introduced." — T. B. Flower. 



Pici'is hierncioirhs, Linn., var. arcalis. " Sychtyn Lime rocks, Slirop- 

 shire." — Miss E. Jonks. The specimens sent by Miss Jones show that 

 P. arvalis, .lord, passes gradually into normal P. Jiieracioides. All Miss 

 Jones's specimens are taller, more slender, and with less spreadinj^ branches 

 than P. Jiieracioides as it grows on the chalk of the S.E. of England, and 

 a few of them have the snbnmbellate inflorescence which marks Jordan's 

 ])lant ; but in by far the greater number the branches which bear the 

 anthodes do not spring mostly from one point. 



Hieracixm pedinicidatimi,, Wallroth. Eaihvay bank, at Liveileith, Edin- 

 burgh. ]\Ir. Sadler sends a few specimens of this plant under the name 

 of H. stolouijiorum, W. and K. I have not access to Waldstein anil 

 Kitaibel's work ;* but it. is certainly not the H. stoloiiijhnim of Fries' 

 ' Epicrisis.' Of the latter I possess specimens collected at Frankfort-on- 

 the-Oder, sent me by the late Herr Buck. Fries quotes ' //. pedun- 

 culare,' Wallr., as a variety of //. Pilosella ; but as he quotes the same 

 page of the Sched. Crit. (406) as that on which Wallroth gives his //. 

 pedunculatum, no doubt Fries means to put //. pcdiincidatuiu as a variety 

 of H. Pilosella. Whether it be a variety or subspecies remains to be 

 proved by raising the plant from seed. 



Ilieracium dubinvi, Linn. Dr. Roy sends a specimen of a Hieracium 

 which was noticed several years ago, by the Eev. James Keith, of Forres, 

 on a piece of waste ground near that town. I believe it to be the plant 

 formerly named by Fries, H. collinum, but which he now considers to 

 be the true H. diibium of Linnaeus. The periclines of the only Forres 

 specimen I have seen are smaller, the peduncles longer, and the leaves 

 on the stolons less developed than in the ordinary form of the Scan- 

 dinavian //. duhiuni ; but Fries states that it is even more protean and 

 polymorphous than the very variable tl. prceaUum, which it replaces in 

 colder countries. I cannot, therefore, speak with certainty as to the name 

 of the Forres plant until I have seen a series of specimens. 



II. Borreri, Syme. Cultivated in Balmuto Garden. The root origi- 

 nally from Mr. Borrer, through Mr. H. C. Watson. It is probably the 

 //. jierfoUatiim, Frolich, though I have a specimen named ' H. Grenieri, 

 Fries,' collected at Freiburg by Dr. Lagger, and sent me last year by 

 Dr. Huter, which conies very near it, though it is more hairy, and with 

 larger and fewer anthodes. H. Gre)iieri is not described by Fries in his 

 ' Epicrisis Hieraciorum ;' but he proposes the name for a plant interme- 

 diate between H. cydoniifolimn, Vill., and //. prenaiithoides, Vill. Dr. 

 Hooker, in the ' Student's Flora,' quotes my //. Borreri as a synonym of 

 //. strictum, with which it has no affinity. Probably this is a clerical 

 error in the position of the synonym, which ought to have been placed 

 under prenanlhoides. 



H. strictum, Fries. Banks of the Devon between tlie Crook of 

 Devon and Rumbling Bridge, Kinross. It occurs very sparingly on rocks 

 by the river-side ; and as the plant seems to be very local, I have thought 

 it advisable to mention this station, although it has been long known in 



* The plant from the railway bank, at Grant on, Edinburf^'li, colleefed by Mr. 

 Sadler, in 186i), certainly agrc-os witli Waidstein and Jviluibel's bcuutifid "figure 

 of//, siolonijiontm. — 11. Trim en.
