32 THE BOTANICAL EXCHANGE CLUB OF THE BRITISH ISLES. 
Callitriche vernalis , Kiitz. Portmeadow, Oxford, July, 1880. — 
G. C. Druce. Rather stagnalis ; see fruit and bracts. — C. C. 
Babington. C. platycarpa. — J. T. Boswell. 
Sedum Forsterianum , Sm., vars. glaucescens and virescens. These 
two (the former from dry exposed rocks at Stanner, the latter from 
shady damp rocks at the cascade of “ Water-break-its-neck,” Radnor- 
shire) were cultivated side by . side, in my garden, under similar 
conditions of light and temperature — /.<?., in a hot dry corner. This 
year the former threw up three times as many heads of bloom, the 
whole plant was more vigorous, and flowered nearly a fortnight earlier 
than the var. virescens. — Augustin Ley. Probably right, but it is 
impossible to be sure of critical forms of dried Sedums. — J. T. 
Boswell. 
Saxifraga sponhemica , Gmel. ? This can hardly be the true plant, 
judging by the presence of buds in the axils of the leaves of the root- 
shoots. It is connected by a perfect series with ordinary hypnoides. 
L., on the cliffs of the Llanthony Valley. — A ugustin Ley. Mr. Baker 
named the specimen submitted to him S. sponhemica. — J. G. 
Hclosciadium, ? Duddingston Loch, July, 1880. — R. H. 
Wood. This is the H. nodiflormn , var. longipedunculatum , F. Schultz, 
which, however, I include under var. repens in E.B., ed. iii., where I 
have mentioned this Duddingston Loch plant. — J. T. Boswell. 
Apiwn nodiflorum , b. repens , of my Manual. — C. C. Babington. 
Linnoea borealis , Gronov. Melberstain Woods, Berwickshire, 
June, 1880. Specimens gathered from a large bed (thirty to forty 
yards in diameter) in a Scotch-fir wood, near Lightfield. This station 
has been known for over forty years, and until the present year 
(1880), when Mr. Stobbs, of Gordon, found it in some other woods 
in Berwickshire, the only known locality in the district. — A ndrew 
Brotherston. 
Galium ochroleucum , Koch. Trusham, South Devon, 12th July, 
1880. In some quantity, on a dry stony hedgebank, with G. verum 
and G. Mollugo. — W. Moyle Rogers. Box Hill, Surrey. — G. 
Nicholson. 
Galium Mollugo , L., var. A dwarf form, with stems not more 
than half a foot long, forming dense masses on the dry coast sand- 
hills north of Deal. — J. G. Baker. I think that I have never seen 
this curious small form ; I presume that it is a form of G. Mollugo . — 
C. C. Babington. 
Galium Mollugo , L., var. Bakeri. Ufton Wood, Warwick, July, 
1878. — R. L. Baker. Not var. Bakeri. — J. G. Baker. 
Galium elongatum , R. Avon, Hill Wootton, Warwickshire, 
August, 1876. — H. Bromwich. The so-named form of G. palustre . — 
C. C. Babington. 
Carduus nutanti-crispus. Roadside, Stanton Wyville, Leicester- 
shire, August, 1880. — F. T. Mott. I call the larger single-headed 
specimen C. acanthoides ; the smaller, with small clustered heads, is 
very near, if not true C. crispus. — C. C. Babington. 
Ce?itaurea nigra , L., var. Teddington, Surrey, July, 1880. — J. G. 
Baker. I would call this var. decipiens without a ray. — J. T. Boswell. 
Hieracium chrysanthum , Backh. Ascent of Loch-na-gar, Aber- 
deenshire, 24th July, 1878. — J. Cosmo Melvill.
