barren in the heads I examined. B. is nearer to squalidus than A. 
or C. A careful examination when in the fresh state would be helpful 
in arriving at a more positive conclusion. I have seen plenty like 
B. at Oxford and Reading, and felt little doubt as to their hybrid 
origin.” — G. C. Druce. 
vS. viscosits^ L. On the ballast of the permanent way near Read- 
ing Station, Berks. Introduced since 1904. Not previously recorded 
for the county. August 1906 — G. Claridge Druce. 
Senecio, ? Odihani, N. Hampshire, 3[st July and 6th 
Sept. 1906. I am sending these specimens wishing to know how to 
name them. No. i came up spontaneously in a very little cultivated 
part of my garden. All sheets are from one plant 4 feet in height, 
and with a girth at the base of stem 2^ inches in circumference. 
No. 2 also all sheets from one plant, growing in a waste piece of 
ground not far off. This one had a more scattered growth than 
No. I, and was quite 5 feet in height. No other senecio was grow- 
ing near except S. vulgaris^ and before this they had not appeared, 
neitlier have I seen any but these two plants. I know not whether 
to refer them to erucifolius, L.,or to Jacobea, L., or whether they 
might be a cross between the two. — C. E. Palmer. “ No. i has 
pubescent achenes, No. 2 glabrous achenes. These are evidently 
a form of S.Jacobcea, L., how much of the variation is due to rich soil, 
and greater shade one can only surmise. So far as a named variety 
these plants come most nearly to .S. netnorosus, Jord., reduced to 
a var. of 6". Jacobcea^ in ‘ Lor. et. Barr. FI. Mons.’ p. 337. Rouy and 
Foucaud give the de.scription ‘ racine bisannuelle, tige plus elevee 
rougeatre, feuilles a pointour obovale, a segments plus larges et plus 
allonges, calatnodes petites en corymbe ample et lache floraison ordt. 
assez tardive.’ These specimens have green stems, but in other 
respect fairly answer the description. I notice, too, that the date of 
flowering agrees with that of this variety. — G. C. Druce. 
S. squalidus, L. Linley, Salop, 4th June 1906, Leg. G. Potts. 
This plant is invading Shropshire on the S.W. side, on the borders 
of Radnorshire ; and on the S.E. side by the Severn Valley.— W. H. 
Painter. “Achenes glabrous; see Rep. for 1904, 24-5.” — 
W. R. L. “ Correct as var. leiocarpus^ — G. C. Druce. 
Cnicus tuberosus, Roth. ? From Nash Point, Glamorgan, v.-c. 
41, 26th July 1906. I send another supply of this thistle (cf. Report 
1904) to say that it does not alter in appearance under cultivation, 
except to grow more luxuriant. I have not been able to get to it at 
Nash Point in the fruiting stage ; and it has not yet shown signs of 
fruiting in the garden, probably because it has not yet flowered very 
freely there. The root is thick, fleshy, and tuberous, much like that
