Phytogeographical Excursion tn the British Isles. 23 
Lindman directed attention to a hitherto undescribed form of 
Polygonium aviculare, and Dr. Moss demonstrated the characters 
of several species of Salicornia and Quercus, which are described 
in his excellent papers on those genera. 
It may be added that the writer has purposely left almost 
unnoticed the Brambles and Roses, and has left unmentioned not 
only many of the planted trees observed, but numerous other 
forms which still require elucidation. 
The names of plants presumably new in name to Britain are 
printed in heavy type. A dagger (+) before a locality or county means 
that it is an addition to the records in Watson’s Topographical 
Botany and Mr. Arthur Bennett’s Supplement thereto. An asterisk 
(*) before a name means that the plant is alien to the British 
Flora, before a locality that the plant is presumably alien to that 
locality. The sign x means a hybrid. The numbers after a 
locality refer to comital numbers of Top. Bot. and Irish Top. Bot. 
The sequence and nomenclature is that of the writer’s List of 
British Plants, which by the kindness of the Delegates of the 
Clarendon Press was supplied to all the foreign members of the 
party. 
4. Thalictrum minus L., in one of its numerous forms was 
observed on an island in the Lower Lake, Killarney 2. 
T. collinum Wallr. is recorded for Killarney in the Cybele 
Hibernica. 
20. Ranunculous acris L. On Ben Lawers 88, the plant which 
Herr Freyn of Prag names for the writer R. Nathorstii Berl. was 
observed at high elevations. The variety BDor@anus (Jord.) 
occurred at Roundstone, Galway 16. 
22. R.bulbosus L. occurred in flower as a form with deeply 
cut leaves (perhaps brachiatus Schleich.) on the limestone rocks, 
near Ballyvaghan, Co. Clare 9, 
24. R. Flammula L. as the sub-species or species 26. R. 
Scoticus Marshall was noticed in loughs about Craigga More, but 
it may be that this form is not quite identical with the Scottish 
specimens. Dr. Glück is going to test its permanence of in 
cultivation. 
48. Caltha palustris L. : a form of this with smaller but con- 
tiguous sepals occurred on the margins of one or two of the 
Norfolk Broads, flowering in August. 
49. C. radicans Forster, near Butterston Loch,t Perth 7 
E. 89. 
77 bis. Castalia candida (Presl.) Schinz & Thellung (Nymphaea 
candida Presl. Delic. Prag. 224), was pointed out by Dr. Ostenfeld 
in a loch in the Dunkeld policies, |East Perth 89. In this locality 
it was in company with introduced species, and might possibly have 
been introduced with them. But its occurrence in undoubtedly
