EEPOKT or THB BOTANICAL EXCHANOS CLUB. 281 



1875." A striking variety, of dwarf habit, having heads with a ray 

 of conspicuous patent ligulate florets, at least one-third the length of 

 the authodes (in the fresh plant). A few dozen of small plants were 

 growing in sand that had been blown from the shore up over a low 

 cliff. Noticed again in the spring of 1876. — T. E. A. B. This 

 seems precisely the plant mentioned in the Bot. Ex. Club Report cited 

 above. The second generation from the Cork plant retains the ray, 

 which is at first flat and then becomes revolute. Every seed seems 

 to germinate. If >S'. squalidiis be not in the neighbourhood of the 

 East Cornwall plant, my supposition that it is a variety of S. vulgaris 

 will be strengthened. Mr. Carroll, I believe, si ill thinks it a hybrid 

 between 8. vulgaris and S. squalidiis. — J. T. Boswell. Tregantle 

 is about five or six miles from Plymouth, in which neighbourhood 

 S. squalidus is unknown. — T. R. A. B, 



Bidens '' hgbrida.''' " Surrey side of Thames at Putney, October. 

 1875." — J. L. Wakren. This form of Bidens I have formerly, 

 received from Mr. Warren, gathered on the banks of the Willesden 

 Canal, Middlesex. I at that time thought it might be a hybrid between 

 B. cemua and B. tripartita, but I now believe it to be a luxuriant form 

 of B. tripartita, into the ordinary state of which it seems to pass 

 imperceptibly. It is distinguishable by the leaves being undivided — 

 that is, not having lateral lobes which give them their tripartite form. 

 The anthodes have a broader pericline and more numerous florets, 

 and the fruit has frequently three or even four awns, although the 

 lateral ones are always much longer than the inner and outer. The 

 root is precisely similar to that of ordinary B. tripartita, having the 

 root-fibres irregularly disposed, not produced from the lower nodes of 

 the stem as in B. certiua, from which it difi'ers also in the stalked 

 leaves, with much broader lamince, and the erect or suberect au- 

 thodes, — J. T. Boswell. 



Hieracium duhium, Linn., Fries. " Root from Selkirk, July, 1873. 

 There is certainly some mistake about this plant in the * Students' 

 Elora.' The description does not fit the Selkirk plant in several im- 

 portant points. The only other description that I have seen (except- 

 ing that in the Trans. Bot. Soc, Edinburgh) is that of H. duhium in 

 Withering, which is not the same plant. I will try next season to 

 get wild examples," — A. Brotheestok. I think this is H. jjratetise, 

 Tausch. — J, T, Boswell, 



Hieracium strictum, Eries. "Aberdona, Clackmannan, August, 

 1875." — Tom Deummond. Mr. Drummond also sends a plant from 

 Linmill in the same county, which he has labelled as a " broad-leaved 

 form" of this, but both Dr. Boswell and Prof. Babington have doubts 

 as to what this latter is. I have sent it out with a query against the 

 name. — T. R. A. B. May be IT. elatum, Fries, with the description 

 of which it agrees pretty well, except that the leaves of our plant are 

 not " inciso-dentatay — J. T. Boswell. 



Erica tetralici-ciliaris, Syme. "Near Penryn, W. Cornwall, 

 August, 1875. I have found this very fine and in great abundance 

 about half a mile from the station, where I obtained the specimens 

 sent in 1874. I noticed what I consider to be another hybrid form 

 with corolla as large as in Baleocia polifolia. I proposed taking a 

 supply for distribution at a subsequent visit, as only a few plants were
