vegetation at this spot was luxuriant, but there occurred also the 
usual form. Approaching var. mite Koch “ foliis caulinis sinuatis, 
rameis integris vel dentatis mitius spinosis.” — W. C. Barton. 
Centaurea obscura Jord. [478]. Rocky banks of R. Wye, 
Boughrood, Radnor, v.c. 43, Aug. 30, 1920. — W. C. Barton. All 
the specimens included in this gathering have the habit and large 
globose heads of C. obscura Jord., under which they must be 
placed. The phyllary-appendages recall those of C. nemoralis 
Jord., ranging in shape as they do from subulate, lanceolate- 
linear, at the base of the capitulum, with the upper series 
lanceolate and ovate-lanceolate, the uppermost only being round- 
ish. The appendages of C. obscura Jord. should be broadly ovate, 
roundish or reniform. The plant is certainly not C. nemoralis 
Jord., which besides the character of the linear-lanceolate 
phyllary-appendages, is distinguished by its smaller ovoid heads 
borne on more numerous branches. The appendages of this 
R. Wye plant are black or blackish-brown, closely imbricated or 
spaced, and then allowing the green phyllaries to be seen. The 
lowest series of appendages may be spreading or recurved. I 
associate this plant with others known to me, to which I have 
given a MS. varietal name denoting the resemblance to C. 
nemoralis Jord. Dr. Druce has also gathered somewhat similar 
forms in Essex and Caithness. — C. E. Britton. 
Hieracium rubicundum F. J. H. Walk Mill Bay, Orphir, 
Orkney, 3 Aug, 1920. — R. J. Burdon. Apparently so, with 
smaller heads than usual. — H.J.R. I think a small flowered 
form of this. — H. W. Pugsley. 
E. scoticum F. J. Hanb. [502]. Rocks near Penwyllt, Upper 
Tawe Glen, Brecon v.c. 42, Aug. 21, 1920. — W. C. Barton. 
These plants are identical with those gathered by the late Rev. 
A. Ley at Penwyllt, July 1906, and named E. scoticum F.J.H. 
The Welsh form. — J. Cryer. Yes ; looks very much like my 
Scotch scoticum. — LI. J. Riddelsdell. 
E. serratifrons Almg var. lepistoides Johanes. [505] teste J. 
Cryer. Railway banks, Aberedw, Radnor, v.c. 43, Aug 23, 
1920. — W. C. Barton. E. pellucidum Laes tad, top sheet ; I doubt 
if the others are (all) that. — H.J.R. 
E. mutabile Ley. (506). Railway banks, Aberedw, Radnor, 
v.c. 43, Aug. 23, 1920. — W. C. Barton. I agree, at least to 
most. — H.J.R.
