Taraxacum officinale^ var. T. cor?iiculatufn, DC. On limestone, 
near Shirley, Derby, May, 1895. This departs from erythrosper^num^ 
Andrz. in the achenes being pale with only a slight rufous tinge, and 
by the horns being for the most part strongly developed. Possibly, 
however, it may be a limestone form of the latter. — Wm. R. Linton. 
T. officinale^ var. Kniveton, Derby, May, 1895. On limestone 
debris. Inner phyllaries simple at the tip, outer not fully reflexed. — 
Wm. R. Linton. Messrs. Groves write : — ‘AVe have not made out 
these limestone forms of Taraxacum.” 
Hieracium callistophylhwi, F. J. Hanb. Root from near Kings- 
house, vice-county 98, Argyle. Garden, Milford, 5th June, 1895. — 
E. S. Marshall. “Yes.”— F. J. Hanbury. 
H . . Limestone scars on Ingleboro, July, 1895. — Geo. 
Webster. “These are all H. anglicum, Fr.” — F. J. Hanbury. 
H. murorum., L. pt. var. cordigerum, Norrlin. Scarp, Outer 
Hebrides, Scotland, September, 1894. Coll. W. S. Duncan. Com. 
Arthur Bennett. “ These are all anglicum.” — F. J. Hanbury. 
II. anglicum, Fr. var. b. acutifolium, Backh. Basalt cliffs, Cave 
Hill, Belfast, 20th July, 1895 (“Yfi a 7 iglicum, Fr.” for one specimen; 
the other indeterminable; either an anglicum form, or else “iY. iricum., 
Fr.,” F. J. Hanbury). Basaltic rocks, Sallagh Braes, Co. Antrim, 17th 
July, 1893. (“One sheet correct; the others var. d. lo 7 igibracteatui 7 iff 
F. J. Hanbury). Basaltic cliffs, Agnew’s Hill, Co. Antrim, 7th July, 
1895. (“Correct.” — F. J. Hanbury). The ten specimens I send 
are from three localities in a range of over twenty miles on the seaward 
escarpments of the basalt plateau of Co. Antrim. The leaf-dentition 
varies considerably, but they all seem to me referable to the above. — 
S. A. Stewart. “ This parcel is much mixed. One sheet, retained 
by me, is no form of H. anglicu 77 i at all. The rest I have placed as 
above.” — F. J. Hanbury. 
H. 77 iuroru 77 i., L. Walton Craig, Keswick. Coll. Bolton King, 
1879. Cultivated, 15th July, 1895. — C. E. Palmer. “These speci- 
mens are all H. anglicu 7 n, var. c. j aculifoliu 77 i.” — F. J. Hanbury. 
H. cloven se., Linton, var. b. Griffithii, F. J. Hanb. Nant Francon, 
August, 1894. — Jno. E. Griffith. “This is the plant described by 
me under the above name. But Mr. Linton has since pointed out to 
me strong reasons why it should not be united with H. clovense, with 
which I concur. The name had better stand, therefore, as simply 
H. Griffithii” — F. J. Hanbury. 
H. Farrense, F. J. Hanb. Great Ormes Head, August, 1894. — 
Jno. E. Griffith. “These appear to me to be correctly named, but 
I feel sure the specimens are cultivated examples, and, if so, ought to 
be so described on the labels.” — F. J. Hanbury.
