come under C. consimilis x nemoralis, though one of the parents may- 

 be C. Deheauxii, which occurs in S. England. My examples do not 

 show fruit, which is useful in dealing with these Centaurea forms, but 

 they agree with C. consimilis in the longly-ciliate, somewhat lax 

 araneuse phyllaries, and with C. nemoralis in the deeper-coloured 

 appendages and strongly inflated stem apex." — J. A. Wheldon. 

 " Mr Adamson remarks : — ' A very distiact small-headed form, which 

 seems like C. Deheauxii G. & G.' I do not think this will do for C. 

 Debeauxii G. & G., but I think it must be a nigra (including obscura 

 Jord. and nemoralis Jord. ) form, rather than coming under pratensis 

 Thuill., in which group Rouy (Fl. Fr.) places C. Debeauxii as a ' forme ' 

 of C. microptilon Gren," — C. E. Salmon. " C. nigra L. cf. sub.-sp. 

 nemoralis (Jord.) Gugler, acced. ad sub -sp. Debeauxii (G.G.) Gugler."

Centaurea melitensis L. Par, E. Cornwall, v.-c. 2, July 10, 1914. 

 This plant was in good quantity at Par this year. Many plants were 

 small, but there were three fine ones like good Centaurea nigra. — 

 C. C. ViGURS. "Yes."— A. Thellung. 



Centaurea ? [Ref. No. 627.] On cotton-seed refuse with 



many other aliens, Hythe Quay, Colchester, N. Essex, v.-c. 19, June 

 16, 1914. Near C. Calcitrapa L., but flower bright yellow; no 

 supplementary spines at base of large involucral spines ; leaves with 

 broader segments. — -G. C. Brown. " An early state of C. Calcitrapa 

 L., is it nof?" — E. S. Marshall. "This is C. Calcitrapa L." — R. S. 

 Adamson. "This is C. pallescens Del., var. typica Gugler and Thellung, 

 forma hyalolepis Gugler. See Thellung Adv. Fl. Montpellier p. 546, 

 1912."— A. Thellung. 



Centaurea aspera L. Hayfield, Tottington, v.-c. 28, July 23, 1914. 

 — F. Robinson. "Yes, var. genuina Willk." — R. S. Adamson. "Recte." 

 — A. Thellung. 



Carthamus tinctorius L. On rubbish by the canal, Litherland, 

 S. Lanes, v.-c. 59, September 5, 1914. — ^J. A. Wheldon and W. G. 

 Travis. "Yes." — A. Thellung. 



Picris Hieracoides L., var. gracilis (Jord.). Letcombe Castle, 

 Berks, August 1901. This variety is described by Rouy {Fl. Fr., x., 

 p. 23) as "plus grele, pauciflore, a pubescence plus tenue, bien moins 

 hispide ; feuilles pubescentes, a peine rudes, plus brievement dentees, 

 calathides ± contractees a la maturite. ' These characters we might 

 assume to be caused by the habitat — dry chalk downs — on which it 

 grew, — G. C. Druce. 



Crepis biennis L. Edge of cultivated land, Walton, v.-c. 28, June 

 9, 1914.— F. Robinson. " Yes ; not given for 28 in Top. Bot. This
