286 RKrORT OF THE BOTANICAL EXCHANfiK CLm. 



style considerably shorter than the fruit which distinj^uish the 

 former; but the nuts as conspicuously stipitate and the exterior 

 membranous keel as dentate as in Z. pedicellata. Reichenbach in his 

 " Fl. Germ. Excurs.," p. 7, describes a Z. gihherosa which may be the 

 present form, but of this I have no specimens. Perhaps it is figured 

 in lleichenbach's " Fl. Germ, et Helv,," but I have not access to 

 that work. With regard to the Orkney Zannichcllia, it differs from 

 authentic specimens of Nolte's Z. polycarpa, by having longer styles 

 with the stigma mostly deciduous, the nuts more slender and less 

 connivent. It is precisely similar to specimens sent out to Mr. 

 Watson by Prof. Reichenbach, under the name of ZannicheUux poly- 

 carpa, /?. temiissiinci, Fries, from the Island of Zealand. The true 

 poh/carpa appears to have been collected in brackish water, as Mr. 

 Watson has been good enough to present me with specimens col- 

 lected by Prof. Reichenbach in Nolte's station, which are labelled. 

 " In the Baltic Sea itself at Eeiligenhavn." It should be looked 

 for in the Lower Loch of Stenness, Orkney, in which the water is 

 brackish. — J. T. Boswkll. 



Zatmichellin " paliisiris." " Brook at Woodloea, near Warwick, 

 October, 1875." — H. Bromwicii. This appears to be the same 

 form as the plant just noticed from Mr. Warren. It has the group o 

 carpels pedunculate, and each carpel shortly stipitate. — J. T. BoswicLL.f 

 Jiuppia rostcJIata, Koch. " Marsh Dykes, Faversham, Kent, 

 September, 187o." — F. J. Hanbury. " Bidston Marsh, Cheshire, July, 

 1875." — R. Browx. This segregate is not named for either of these 

 countries in " Topographical Botany." 



Scirpiis carinatm, Sm. " By the Tamar, near Oawton, Beer 

 Ferris, S. Devon, 1875." Noticed from being from a recently-dis- 

 covered station ; it likewise occurs on the E. Cornwall side of the 

 river, where it was detected last summer by Mr. Ralfs, of Penxance. 

 I consider it a very unsatisfactory species, for whilst it sometimes has 

 stems bluntly trigonous for nearly their whole length, at others 

 they are round from two to three inches below the panicle, and 

 they vary in shape even on the same root, the smaller stems as a 

 rule being more conspicuously trigonous than the larger. — T. R. A. B. 

 Carcx punctata, Gaud. " Clilf by Bigbury Bay, S. Devon, 

 July and August, 1875." Grows rather sparingly on home low rocks 

 under a cliff, where it is probably not unfrequently dashed with spray 

 from the waves. It occurs mostly intermixed with coarse grassy 

 vegetation, and Carex extensa may be seen near it. The locality is 

 just four degrees west longitude. — T. R. A. B. 



Psamma baltica, R. & S. "Ross Links, ^Northumberland, 

 August, 1875." — AVm. Richardson ; also sent by Mk. Rrother.ston", 

 who observes : " If last season may be taken aa an average one, it 

 will be some time ere every botanist in the country gets an example 

 of this plant. When I visited Ihe station in August last I saw plenty 

 of plants, but very few of them were flowering. The common species 

 was the same in that respect. When seen growing together JP. 

 baltica is easily distinguished by the leaf ; it is much broader and 

 flatter than in P. arena ria, and the grass is altogether a stronger 

 growing plant."
