THE BOTANICAL EXCHANGE CLUB OF THE BRITISH ISLES. 
Sussex, Sept, 1882. — A. Bennett. Differs from Jordan’s arualis 
in having the heads much less umbellate. — J. T. Boswell. 
Taraxacum palustre , or udmn ? Sphagnum swamps, Devil’s 
Punch-bowl, Surrey, 13th May, 1882. — W. H. Beeby. I should call 
this palustre certainly. T. udum , of Jordan, as I understand it, is a 
much larger plant, with distinctly runcinate leaves and with a few of 
the outermost phyllaries reflexed, but I have seen heads from the 
same root with the phyllaries all applied, and some of them with the 
phyllaries reflexed. — J. T. Boswell. I considered the above to be 
palustre , and different from the plant referred to by Watson to T. 
udum , Jord., which latter occurs in various parts of Surrey. — W. H. B. 
* Crepis nicceensis , Balb. Pasture recently laid down near 
Pontrilas, Herefordshire, 21st June, 1882. — A. Ley. 
Hieracium anglicum , Fr., var. decipiens , Syme. Basaltic rocks, 
Cave Hill, Belfast, 5th July, 1882. — S. A. Stewart. 
H. anglicum , Fr. Strome Ferry, W. Ross, July, 1881. — G. C. 
Druce. Probably correct. — J. G. Baker. 
H. caesium , Fr. Great Doward Hill, Herefordshire, 2nd June, 
1882. Name on the authority of Mr. J. G. Baker. It grows inter- 
mixed with H. murorum , and under the same conditions of light and 
temperature, and differs from this species conspicuously (1) by the 
reddish green leaves, especially the under side of the root leaves ; (2) 
by the phyllaries more swollen, and of a much greyer green ; (3) by 
the straight peduncles ; and (4) by the slightly earlier period of 
flowering. —Augustin Ley. 
H. ccesium , var. cambricum. See “J. of Bot.,” vol. VIII., p. 362 
J. E. Griffith. 
H. tridendatum ? Harrogate, Yorks., 4th August, 1882. — E. F. 
Linton. This seems to me quite typical tridentaium. — J. G. Baker. 
H. corymbosum , Fries. Killin, Mid-Perth, August, 1882. I send 
up some more specimens of a Hieracium from Killin, of which, 
according to the Exch, Club Report for 1879, Dr. Boswell would not 
certainly pronounce whether it was H. strictum or H. corymbosum , 
though he inclined to the latter name. I hope with fresh specimens 
it may be more easy to decide which of the two forms it shall be 
called. It was fairly abundant this last summer, always growing 
down in the valley, and usually not far from one of the two streams 
which feed Loch Tay. — E. F. Linton. I cannot draw any clear line 
between crocatum and corymbosum. — J. G. Baker. This plant is 
referred to H. corymbosum by Mr. Backhouse. I still think this is 
H. corymbosum. The Rev. E. Linton was good enough to send me 
fresh specimens in 1882, but I was unfortunately from home at the 
time, and, on my return, they were too much withered to be 
recognisable ; and still more unfortunately, though I planted the 
roots, they did not grow. In no genus is cultivation more important 
than in Hieracia. Many species which closely resemble each other 
in the wild state become widely different when cultivated. H. 
anglicum and H. iricui?i are examples of this. — J. T. Boswell. 
H. corymbosum , Fr. Cliffs between St. Andrews and Kinkell 
Ness, N. E. Fife, 8th August, 1882 . — Charles Bailey. “ I 
think that your Hieracium from the neighbourhood of St. Andrews 
is H. corymbosum , Fries., though it differs a good deal from
