richer in England than it was some centuries ago,—e.g., the elm, 
the walnut, and the horse chestnut, how abundant they were. 
As to the Hordeum murinum, he could not help thinking that it 
must have been plentiful in his boyish days, having a vivid 
recollection of the schoolboy tricks that used to be played him of 
putting the ears up his sleeves. Plants were confined to certain 
places very often, and did not range far beyond the spot where 
_they were introduced. The Atlantic plants were only found on 
the west coasts, for instance, and also in the south of Ireland 
certain plants were found that had their origin in Portugal. The 
Rosa hibernica is only found in one place in Ireland ; every other 
plant there was either European or American. As a curious 
instance of the appearance and disappearance of foreign plants, 
shortly after the Swinford Flax Mill, near Bitton, was built, the 
road was blue with the beautiful little flax flower, which dis- 
appeared together with the trade in that commodity. And he well 
remembered visits which he used to pay to a rough uncultivated 
field in the neighbourhood with his friends Buckle and Broome, 
often finding at least fourteen different species of orchids; but 
the plough being turned in all these had in ashort time vanished, 
and he was glad to say the corn crop, too, shortly after failed 
likewise. The London rocket, too, was a curious example of the 
movement of plants. It was well known that it first came in 
after the fire of London, never having been seen before. Owing 
to the extension of the railways it suddenly appeared near 
Newcastle-on-Tyne, having been introduced there in a ballast 
heap,, As to the great destruction of plants on Shapwick Moor, 
he found a very rare plant there in 1870, the Andromeda ; indeed, 
several plants were thought to have been extirpated, but really 
had not been. The Lpipactis rubra still exists at Painswick, and 
was, found by Sir Joseph Hooker during a visit there this 
year. Mr. Blomefield had spoken of that curious and rare plant, 
the Herminium monorchis, and its tuber-bearing peculiarity. He 
would mention the Crinum Capense as similar in its method of
