Four Alien plants not in my List of British Plants were also 
gathered on the Excursion, viz., Saponaria orientalis L., an eastern 
species introduced with other Aliens at Galway Bay: Populus 
laurifolius Ledeb., the remains of cultivation in the Earl of

evidently planted at Southport. The last was identified by 
Professor Graebner.
