Carex aquatilis, Walil., b. Watsoni. Banks of the Thurso River, 

 Caithness. July, 1875. Clyde-side at Kenmure, 5 miles above 

 Glasgow, June, 1876. — G. Horn. This seems really to be the type 

 of the species. — J. T. Boswell. 



C. ccanthocarpa, Degland. ; C.fulva, var. sterilis, *E. B.,' ed. 3, 

 vol. X., p. 153 ; C. fidva, Koch et Auct. plur. (non Smith). Marsh 

 at Piggar, Swanbister, Orphir, Orkney. August, 1875. I found 

 one or two tufts of this growing in company with C. flava and 

 C.fulva {Hornsuchianana, Hoppe.) I have no doubt it is a hybrid 

 between these two plants. It grows in much denser tufts than the 

 latter, and the herbage is of a paler and yellower green ; but its 

 affinities and habit agree with fulva, Sm., not with flava, L. (See 

 Mr. R. A. Pryor's remarks on this in ' Journal of Botany,' 1876, 

 p. 366-370.) My experience has agreed with that of the late M. 

 Boreau, for the plant has remained unchanged under cultivation 

 for two years, but it has produced no mature fruit. The perigynium, 

 either in the wild or in the cultivated Orkney plant, has not become 

 inflated ; the differences which C. ccanthocarpa exhibits in different 

 localities, — in some approaching more towards C. flava, and in 

 others to C.fulva, — are indications of its hybrid origin, as well as 

 its intermediate characters and habit, and, above all, its abortive 

 fruit. The Orkney specimens are the only British ones of 

 C. xanthocarpa that I have yet seen. — J. T. Boswell. 



Anthoxanthum Puelii, Lee. et Lam. On peaty ground, near the 

 south-eastern extremity of Lindow Common, Hundred of Maccles- 

 field, Cheshire, the rifle-range being about a quarter of a mile N.W. 

 August 26, 1876. {Vide 'Journ. Bot.,' October, 1876, p. 809.) It 

 grew freely on peaty ground, which, I am of opinion, from its 

 appearance, originally formed part of the adjacent waste bog, but 

 has been reclaimed at some distant date. It is crossed by a cart- 

 track, apparently used for conveying turf from the moss. Most of 

 the ground in question was covered with grass and weeds, but 

 there were some patches of potatoes. Extending over a length of 

 from twenty to thirty yards, the Anthoxanthum grew in fair quantity, 

 with all the appearance of being native, among grass and common 

 weeds (no introduced plants.) It is, however, possible it may have 

 been introduced with grass-seed. On closer examination of the 

 specimens, I find some differ slightly from the example gathered 

 by Mr. Briggs, and furnished me through the Exchange Club, in 

 having all the parts rather larger, and the spikes and whole plant 

 more robust. The peculiar scent is also stronger. All these 

 differences may, however, be owing to the richness of the peat -soil 

 on which they grew. The seeds of this grass may probably have 

 been introduced when this part of the old bog was reclaimed. — 

 Robert Brown.
