Serratula tinctoria , L. Burnham, 1895, and near Bulstrode, 1897, 
Bucks. New county record. — G. C. Druce. 
Serratula tinctoria , L., form intermediate between type and var. 
monticola , Boreau. Foot of Freshwater Downs, Isle of Wight, August 
1891. Coll. Capt. Steuart; comm. J. A. Wheldon. “I have gathered 
it in the same locality still more reduced as a plant, two inches high, 
and with a single capitulum.” — G. C. Druce. 
Centaurea nigra , L., var. decipiens , Thuillier. Freshwater Downs, 
Isle of Wight, September 1894. Coll. Capt. Steuart; comm. J. A. 
Wheldon. “ C. nigra , var. decipiens, Thuill., ‘ FI. Paris,’ ed. ii., 
p. 445 (as a species). A dwarf form of the above. There are 
specimens of the same plant in the National Herbarium from near 
Torquay, and Freshwater Downs. Dr. Beck, in the ‘Flora von Nieder- 
Oesterreich.,’ p. 1263, has two forms of C. decipiens-. (1) typica, lower 
leaves lobed ; (2) sub-jacea , leaves unlobed.” — E. G. Baker. “ Is C. 
serotina , Boreau, forma. A form probably due to injury of the 
terminal bud, or to unfavourable conditions of growth.” — J. Freyn. 
Centaurea , sp. Growing in patches here and there on the sand 
dunes on both sides of Tongue Bay. Typical Centaurea Scabiosa and 
nigra are plentiful on the dunes. M.ilness, and near Coalbackie 
26th and 31st July 1897. — E. S. Marshall and W. A. Shoolbred. 
“ I have not been able to match this in the general herbarium of the 
British Museum. It grew with C. nigra and abundance of C. Scabiosa, 
but had no appearance of hybridity. I believe it to be either a 
marked variety of the latter, which it resembles in inflorescence, or 
a new, distinct, but allied species.” — E. S. Marshall. “ An interesting 
variety of C. Scabiosa, L. Dr. Beck in the ‘ Flora von Nieder- 
Oesterreich,’ p. 1259, deals at some length with the forms and 
varieties of this plant. The primary characters he relies on for 
sub-dividing the varieties, are ‘(r) Hautrand und Anhaengel der 
Schuppen deren Nagel nicht verdeckend ; (2) Hautrand und Anhaengel 
der Huellschuppen sehr breit, schwarz die Nagel verhiillend, die 
Huelle daher schwarz ersheinend.’ Under division (1) come var. 
typica and badensis, Tratt. (‘Arch.,’ i., 8, t. 50, as species); five forms 
of the first being enumerated, some of them having entire lower leaves. 
Under division (2) come campestris and Kotschpana, Koch, (‘Synop.,’ 
ed. ii, 473; Reich, fil. ‘ Icon.,’ xv., 27, t. 44, fig. 1). I see there is a 
form of integrifolia, a. typica , but I have not seen specimens of this.” — • 
E. G. Baker. “ A very remarkable plant, which has not hitherto 
come under my notice. Judging from the character of the heads, it 
belongs to the group of forms designated C. Scabiosa, a. vulgaris, by 
Koch, in his ‘Synopsis;’ but the branching of the rhizome appears 
to be rosular, whereas C. Scabiosa develops terminal stems and has 
no rhizomes. This specimen is without the parts which I consider 
to be the most important, and a satisfactory decision can only be 
arrived at by several specimens. In any case, this Centaurea is highly 
interesting.” — J. Freyn.
