574 the botanical exchange club of the BRITISH ISLES. 
yellow styles, non-ciliate ligules, and much narrower leaves, which 
are floccose beneath. The specimens are rather weak and imma- 
ture.— Edward S. Marshall. Though the leaves of No. 3533 
are not so long and linear-lanceolate as the most typical British 
specimens or the Scandinavian type, this is good H. angustum, 
Lindeb., in all other respects. Mr. Marshall has some reason 
for distinguishing this from H, strictum, and replacing it as a 
species. — E. F. Linton. 
Hieracium corymbosum, Fr., var. salicifolium (Lindeb.). [ref. 
3534]- Wooded banks of the Orchy, Dalmally, Argyle, v.-c. 
98, July 25, 1910. Styles sooty; ligules pale lemon )ellow, 
glabrous-tipped. Rev. Augustin Ley agrees with my suggested 
meaning ; the absence of floccose clothing on the underside of the 
leaves is probably due to shade. Very unlike typical corymbosn/n, 
as I know it in Scotland ; but Mr. Ley tells me that in Wales the 
two run into one another. — Edward S. Marshall. Agrees with 
some other plants we have so named ; floccose and pilose clothing 
is often denuded by shade. — E. F. Linton. 
Hieracium sabaudiim, L., var. calvaium, F. J. H. Origin, 
Aberedw, Radnor, cult. August 16, 1910. I must speak with doubt 
concerning the varietal name of this plant. It differs from the 
Carnarvonshire plant originally so named by Mr. Hanbury, in having 
its leaves oval or broadly oval, instead of broadly elliptic ; but agrees 
in its glabrous stem, black phyllaries, and especially in the com- 
paratively few leaves. — Augustin Ley. Mr. Hanbury describes 
this under H. boreale^ Fr., which I think should be retained for our 
species. The existence of true H. sabaudum^ L., in Britain has 
been freely disputed. — Edward S. Marshall. 
Taraxacum Icevigatum, DC. [ref. No. 2001]. Tubney, Berks, 
June 1909. This equals T. crythrospcrmum, Andr., according to 
Handel-Mazzetti ‘ Mon.’ p. 100, the T. Iczvigatum of English 
authors being for the most part T. obliquum, Dahlst., which is the 
Leontodo 7 i obliquum. Fries., and not the L. Icevigatus, Willd., sp. 
pi. iii. 1546, 1800. — G. Claridge Druce. The essential fruit is 
absent from my two specimens. De Candolle (‘ Prodromus,’ 
p. 146) gives his own name as the authority; and quotes Leontodon 
Iccvigatus, Willd., as a synonym. In his monograph Handel- 
Mazzetti says that Willdenow’s original plant has red achenes, and 
substitutes Icevigatum as the name for our erythrospermum ; thus 
introducing an altogether unnecessary confusion, and adopting a 
course which is contrary to the Vienna Rules. — Edward S. 
Marshall. Where is the disobedience to the Vienna Rules ? — 
G. Claridge Druce.
