Pliytogeograpical Excursion in the British Isles. 319 
This newly described species was rather common in the general 
salt-marsh association to the north of Hayling Island. It is easily 
distinguished by its short and uniflorous “spikes.” 
2164. Dondla fruticosa Druce ( Suceda fmticosa Forskal). 
Shingle of Blakeney, in magnificent growth, nearly at its most 
northern station in Europe. 
2166. D. maritima Druce ( Suceda maritima). Both in the 
erect and prostrate (var. procumbent Druce) conditions at Hayling 
Island; also a procumbent large seeded form with seeds ripening 
earlier which is probably the var. macrocarpa moquin. 
2171. Polygonum Bistorta L. In meadows by the Teith 
Callander f87. 
2200. Rumex obtusifolius x nemorosus=R. Dufftii Hausskn. 
Monsal Dale (‘57. Greenfield, York f63. 
2207. Rumex maritimus L. Near Sutton Broad 27. 
2210. Rumex Acetosellci L. var. angiocarpus (Murbeck). The 
common plants of the British Isles. Noticed at Greenfield, York 63, 
Southport, Lancashire 59, near Penrith, Cumberland 70, near 
Whitbarrow, Westmoreland 69, Dunkeld 88, Perth, and at 
Perranwell, Cornwall 1. 
2210. Rumex Acetosa L. var. acetoselloides (Bah). Grew on 
Chewbrook Clough, above Greenfield +63, near the New Reservoir, 
pointed out by Dr. Ostenfeld. 
2219. Euphorbia hyberna L. Common in fruit at Killarney. 
2245. Ulmus glabra Miller. Tall trees nearly 100 feet high 
at *Mallow +5, * Killarney +2, *Callander +87. Probably planted 
in these localities. 
2246. U. stricta Lindley. Near *Gort, Galway f 15, Perranwell, 
etc. 1, near Beaulieu, etc. +11. 
2246. Ulmus hollandica Miller. *Meltham +63, Mallow +5, 
Killarney +2, near Cork. 
2247. Humulus Lupulus L. Near Clifden, close by a cottage, 
Galway *+16. 
2255. Betida alba L, (B. verrucosa Ehrh.). Plentiful near 
Honley 63, seen in Silverdale 69, Dunkeld 88, Aberfeldy 89, 
Trossachs 87, Killarney 2. But with this birch and B. pubescens 
were very numerous trees which could not be referred to either 
species. Some of these, as at Westwood 63 and Killarney, are 
probably true hybrids (B. alba x pubescens ), but in addition there 
are several well marked varieties including B. pubescens Ehrh. var. 
parvifolia (Wimm.) and var. carpatica W. & K. and another distinct 
looking tree which is common at Killarney and is perhaps somewhat 
nearer to B. verrucosa. B. piibescens Ehrh. occurred near Wood- 
bastwick 27, at Foulshaw Moor 69, Dunkeld 89, Aberfeldy 88, 
Trossachs 87. 
2267. Salix pentandra L. In several localities near Clifden, 
Galway, but perhaps originally introduced. 
2272. 5. daphnoides Vill. var. pomeranica (Willd.). Planted 
doubtless near Southport 59. Professor Graebner named it as 
the above. 
2276. 5. aurita x cinerea=S. lutescens A. Kerner. Several 
bushes of this were seen in the Wessenden Valley, Yorks. +63, also 
near Dunkeld, Perth E. 89, and at Clifden, Co. Galway. 
2291. Populus nigra L. Norfolk +27, +28, Meltham *+63. 
Large trees near Mallow +5.
