The Club is indebted to Mr. F. J. Sheldon, B.Sc., for having 
undertaken the distribution, with the help of Mr. Sherrin, to

on their recent marriage. 
We welcome to the Club a valuable Continental member in 
Dr. Karl Rechinger of Vienna. 
Some useful determinations and notes by Mr. Pearsall upon 
Ranunculus , Euphrasia and Salix, which arrived too late for the 
last Report, are for the most part here appended. Also a 
necessary correction of my own to the Report, 1922 — 23.

Correction in Report, 1922 — 23. 
Both under the photograph and on p. 201 “ Cirsium eriophorum 
Scop, subsp. anglicum Petrak ” should read subsp. britannicum ■ 
Petrak. I did not know this until I received from Dr. Petrak 
that section of his Cirsiotheca Universa; and only last December 
at Brit. Mus. (Nat. Hist.) did I see his “Der Formenkreiss des 
Cirsium eriophorum in Europa,” in Bibliotheca Botanica, Stuttgart, 
1912. The mistake arose through Dr. Petrak having called the 
plant subsp. anglicum in his two letters to me in 1922 and 1923. 
Until last February I had not known of Dr. Druce’s useful 
review in B.E.C. Report, 1913, of Petrak’s paper, which the 
former mentions in Nature , Feb. 27, 1926, when referring to my 
letter on “ Flowering Plants as Epiphytes on Willows and 
Alders” ( Nature , Nov. 14, 1925). It is true that Petrak called 
the plant subsp. britannicum in 1912 and not in 1922, but the 
monograph of the genus Cirsium is still unpublished. — Ii. S.
